A great choice if you want to be prepared for all the vagaries of fate. The set covers a very large amount of work, for all occasions. With it, we have the most basic tools always at our fingertips. However, you should also be aware of kits that have been designed for the craftsman’s specific tasks. The following is a detailed review of specific tool kits and their features:
For work with cars
The set that solves the main automotive problems. This equipment has a place in your trunk, your own garage or even at the service station. A distinctive feature of the set is the obligatory presence of a large number of sockets and adapters of different sizes, ratchets, wrenches, extensions, open-end wrenches, etc. Such a set will protect you from unforeseen breakdowns on the road, or help rescue a friend. In our Internet-shop you can read reviews of our customers about Dnipro-M head sets.
This set specializes in repair and processing of steel, wood and plastic. As a rule includes adjustable wrench, chisels, taps, dies, metal saw, vice, pipe cutters, measuring and other tools. Find widespread use among plumbers and hobbyists to build something in the garage.
The main criterion for selecting a tool kit for electricians is the quality of protection against dangerous voltage levels. For this purpose the manufacturer uses special materials and grip systems that withstand a voltage of 1000 V and provide the necessary safety at work. Such sets in practice include screwdrivers (including for precision work), pliers, side cutters, pliers, pliers, testers for measuring voltage in the network and other auxiliary devices.
For carpentry work
Consisting of planer, trowel, chisels, drills, rasp, bits, carpenter’s hacksaw, jigsaw, measuring and other tools. Such a narrow-profile set is considered professional, and a “universal” set of tools will not always be able to qualitatively compensate for all the necessary functionality.
The most popular hand tool kits are automotive. According to data for 2016, car owners in Ukraine is 202 per thousand people, which means that potentially every fifth resident of the country may need to repair a car.

Into what kinds are links divided?
Our online marketing agency will tell you all the details. All links are divided into two large types: internal and external.
These links lead to a particular site from other resources. External reference mass is formed from them. Find out how often resources refer to a particular site.
There are several types of external links:
- Natural. Put them for people, not for robots. Such links must have information that may be useful to visitors of the site. Most often, these links are placed on the resources of a thematic nature. From natural links is formed a quality link mass.
- Purchased or rented links. Usually such SEO-links are purchased at special exchanges. It is quite possible that search engines negatively evaluate those sites, links to which are placed at such exchanges. Usually put the commercial anchors. In this case there is no advisory nature. These links are usually put for search engines. Sites submitted to the links exchangers, often incredibly spammed. Sanctions of search engines are often probable since such links are perceived extremely negatively by search engines.
There are several variants of external links:
- So in thematic publications are placed article links.
- Crowded links are placed in Комментарии и мнения владельцев on blogs, forums and social networks.
The following types of external links are distinguished:
Anchor. In this case, the anchor is the text, rather than the URL of a page.
There are several types of anchor links:
- Commercial. In this case, the anchors are key queries of a commercial nature. Examples: the words “buy”, “price”, “cost”.
- Branded. These anchors contain the name of a brand or company. An example. Volga Company. Another option. a link to the company’s site without http. Example: “volga.ru”.
- Pseudo-organic anchors. These are the words “here”, “here”, “at the link”.
Anchors can be any phrases or words belonging to the groups listed above. Example: if the article is about cosmetology, a link to the site of a cosmetics company can be placed with the anchor “manufacturer of the best Russian cosmetics.Anchorless links
In this case, the anchor is a link with the mandatory protocol https or http.
Links in the form of images. They are attractive unusual design, but they often do not carry any information that may be useful.
Such links redirects people to those pages which are within a certain domain name. These are links in the menu of the resource, product catalog, etc.д. They are used for easy navigation within the site.
Search engines evaluate not only external reference mass. They also make sure to assess the importance of pages on one site. This is why it is so important to think about the internal structure of the resource and create the right relinking. This will become the optimal systems of quality website promotion in search engines.
Such a man is simply impossible not to notice: he is always confident, charismatic, attractive. He is fashionably and tastefully dressed, and making new acquaintances for him is not worth any difficulty. These types are often successful in their careers, especially in a creative environment. Despite all the charm, such men have their downsides. For example, for them it is always important to the opinion of others, so they spend all their efforts to please everyone. In addition, there is little chance that such a chosen one will be faithful and most likely will switch to other girls.
Types and kinds of power plants
Depending on the energy source, the following types of power plants are distinguished:
- Thermal power plants (TPPs) that use natural fuel. They are subdivided into condensing (CHPP) and combined heat and power (CHPP)
- Hydraulic power plants (HPPs) and pumped storage power plants (PSPPs) that use energy from falling water
- Nuclear power plants (NPPs), using the energy of nuclear decay
- Diesel power plants (DPS)
- Thermal power plants with gas turbine units (GTU) and combined cycle plants (CCPP)
- Solar power plants (SPP)
- Wind power plants (WPPs)
- Geothermal power plants (GEOTPPs)
- Tidal power plants (TPS)
Most often in the modern energy industry distinguish traditional and unconventional power.
Conventional power generation is mainly divided into electric power and thermal power.
The most convenient type of energy. Electrical, which can be considered the basis of civilization. Conversion of primary energy into electric energy at power plants.
A huge amount of electricity is produced and consumed in our country. It is produced almost entirely by three main types of power plants: thermal, nuclear, and hydro.
Approximately 70% of the world’s electricity is generated in thermal power plants. They are divided into condensing thermal power plants (CHPP), which produce only electricity, and combined heat and power plants (CHPP), which produce both electricity and heat.
In Russia about 75% of energy is produced by thermal power plants. Thermal power plants are built in areas where fuel is extracted or in areas where power is consumed. It is profitable to build HPPs on full-flowing mountain rivers. Therefore, the largest HPPs are built on Siberian rivers. the Yenisei, the Angara. However, HPP cascades are also built on lowland rivers. the Volga, the Kama.
NPPs are built in areas where a lot of energy is consumed and other energy resources are scarce (in the western part of the country).
Thermal power plants (TES) are the main type of power plants in Russia. These plants produce about 67% of Russia’s electricity. Their location is influenced by fuel and consumer factors. The most powerful power plants are located in places where fuel is extracted. Thermal power plants using calorific, transportable fuel are oriented to consumers.
A schematic diagram of a thermal power plant is presented in Fig.1. Note that in its design there can be several circuits. The heat from the fuel reactor can go not directly to the turbine, but give its heat in the heat exchanger to the heat of the following circuit, which can already go to the turbine, and can pass its energy to the next circuit. Also, any power plant includes a system for cooling the spent coolant to bring the coolant temperature to the required value for the repeated cycle. If there is a settlement near the power plant, this is achieved by using the heat of the spent coolant to heat water for home heating or hot water supply, and if not, the excessive heat of the spent coolant is simply discharged into the atmosphere in cooling towers. Cooling towers in non-nuclear power plants are most often used as condensers for exhaust steam.
Main equipment of thermal power plants. Steam boiler, turbine, generator, steam condenser, circulating pump.
In the steam generator boiler during fuel combustion heat energy is released, which is converted into water steam energy. In the turbine, the energy of water vapor is converted into mechanical energy of rotation. The generator converts the mechanical rotational energy into electrical energy. The CHP scheme is different in that in addition to electric energy it generates thermal energy by taking a part of steam and using it to heat water, supplied to the heating lines.
There are thermal power plants with gas turbines. Working body and them. gas with air. Gas is released during combustion of fossil fuel and mixed with heated air. The gas-air mixture at 750-770 ° C is fed into the turbine, which rotates the generator. TPPs with gas turbines are more maneuverable, easy to start, stop, regulate. But their capacity is 5-8 times less than that of steam.
The process of electricity generation in a thermal power plant can be divided into three cycles: chemical. combustion process, as a result of which heat is transferred to steam; mechanical. The thermal energy of steam is converted into rotational energy; the electrical. mechanical energy is transformed into electric energy.
The total efficiency of a thermal power plant consists of the product of the efficiency (η) of the cycles:
The efficiency of an ideal mechanical cycle is determined by the so-called Carnot cycle:
where T1 and T2. steam inlet and outlet temperatures of the steam turbine.
At modern thermal power plants T1=550°C (823°C), T2=23°C (296°C).
Practically taking into account losses ηtce=36-39%. Due to full use of thermal energy, CHPP efficiency = 60-65%.
Nuclear power plant differs from thermal power plant in that the boiler is replaced by a nuclear reactor. The heat from the nuclear reaction is used to produce steam.
The primary energy in a nuclear power plant is internal nuclear energy, which is released during nuclear fission as tremendous kinetic energy, which, in turn, is converted into thermal. The plant where these transformations take place is called a reactor.
Heat transfer medium (water, inert gases, etc.) flows through the reactor core.д.). The heat carrier carries the heat away to the steam generator, giving it back to the water. The steam produced flows into the turbine. The reactor power is regulated by special rods. They are injected into the core and change the neutron flux and therefore the intensity of the nuclear reaction.
Natural nuclear fuel of a nuclear power plant. uranium. A layer of concrete several meters thick is used for biological shielding from radiation.
Burning of 1 kg of coal produces 8 kWh of electric energy, and burning of 1 kg of nuclear fuel produces 23 mln. kWh of electricity.
For more than 2000 years mankind has been using the Earth’s water energy. Now water power is used in three types of hydroelectric power plants (HPPs):
- Hydraulic power plants (HPPs);
- Tidal Power Plants (TPG), which harness the tidal energy of the seas and oceans;
- Pumped storage power plants (PSPP), which accumulate and utilize energy from reservoirs and lakes.
Hydropower resources in the turbine of hydroelectric power plants are converted into mechanical energy, which is converted into electrical energy in the generator.
Thus, the main sources of energy are solid fuels, oil, gas, water, the energy of decay of uranium nuclei and other radioactive substances.
All main types of power plants have significant negative impact on the nature. TPPs pollute the air; the slags from coal-fired plants occupy vast areas. Reservoirs of plain HPPs flood fertile floodplain lands, cause land swamping. Nuclear power plants are not safe either.
The future belongs to unconventional energy sources such as wind, tide, solar and the Earth’s internal energy.
Construction of a metal hammer. how to choose a set? Types and purpose of the tool. How it differs from the carpenter’s hammer? Features of models with a round striker
A hammer is the first instrument in the house. And hammer a nail, and split a nut, and deburr a wire. It is the father of all equipment and tools. The development of the production of hammers is characterized by a high level of progress, so for each activity it is easy to find the most effective tool. If you do locksmith work, then you will need a locksmith hammer. No master can do without this percussive tool.

The purpose of a locksmith’s hammer
Mankind has known and used a hammer for a long time. since the dawn of time. It is the very first tool of labor, as well as a weapon of primitive man at the same time. People improved and changed the hammer as they progressed. The materials of the hammers of ancient times corresponded to the development of people and changed in this sequence: bone. wood. bronze.
The design of a hammer in our days has not changed: the butt plate, the striking part with the striker and the handle. The striker and the handle are connected by a hole in the body and a wedge driven into the handle. The tail can be of various shapes. The body is usually made of steel, but can be made of copper, wood, lead, and rubber. The handle is most often made of wood, metal or plastic.
There are many kinds of hammers. Physicians and architects, cooks and musicians, not to mention carpenters, locksmiths, mechanics and builders, use hammers in their work. The most famous hammers are copper hammers, sledge hammers, planer’s hammers, carpenter’s hammers, mason’s hammers and locksmith‘s hammers.
It is the latter that the locksmith’s hammer with a round beater is the most common and versatile. Its purpose is to extend, direct and increase effort of human hand, make a sharp blow to the needed point and help other tools. chisels, chisels, punches.
It is convenient for striking at a variety of work: bending, chopping, riveting, straightening, piercing holes, hammering and flattening. A locksmith’s hammer is used to hammer nails, break concrete or ceramic tile, and shape metal tubes.
Construction of a locksmith’s hammer
Locksmith hammer differs from the usual one by the fact that it has two different beats in the construction: a plain one, which is used for hammering nails, and tapered towards the end, which is convenient for breaking different objects and surfaces. The tool has slightly convex, not beveled and not oblique surface of the striker, without burr, chamfer, burrs, potholes and cracks.
The price of locksmith hammers with a square hammer is cheaper, that is why this variety is widely spread in the locksmith practice for the light works. But hammers with a round striker have one advantage, which is that the striking part greatly outweighs the back part, which provides greater accuracy and striking force.
The impact force through a locksmith’s hammer depends on the severity level of the working part and the movement of the tool. This speed is controlled by man, and the severity of the work piece is controlled by the manufacturer. The striking part of the tool is made of thermally treated steel to ensure high strength and hardness. Therefore, the material used to create hammers is varied.
The striking part of the hammer is usually mounted on an ergonomic handle made of fiberglass or wood. For the handle are used predominantly hard wood (hornbeam, beech, dogwood or birch) and have a length not less than 250 millimeters for hammers. Locksmith hammers weigh 0.4 to 0.8 kilograms.
Making a locksmith‘s hammer
A locksmith’s hammer has one vulnerability: the section of the hammer handle that sits under the striker. When hammering pins, nails, wedges problems arise, especially at the initial stage of their fastening, masters often miss the target and usually hit the nail not with the striker, but with this part of the handle.
This results in chipping and potholes on the handle. Hammers very often become loose, flying off the handle, or break. And buying a locksmith hammer does not guarantee the opposite, since the locksmith hammers do not have a special tongue for protection, as, for example, in the axes.
Of course, in retail outlets and construction stores you can find hammers with plastic or metal handles, which are completely free of the problem of getting the head on, but the traditional locksmith hammers are those with a wooden handle. They also fit more securely in the hand and are warmer to the touch.
So today we will make a locksmith hammer with his own hands with a wooden handle. Remember, all you have to do is get the handle firmly and securely attached to it once, and it will work unquestioningly.
The handle of a locksmith’s hammer
So, let’s start with making a handle for the locksmith’s hammer. Let’s talk about dimensions first: the handle should have an oval cross section, approximately 250 350 millimeters long, tapering smoothly to the end, on which the tool head will be slipped on. The best grip is in beech, oak, birch, maple, hornbeam, ash or mountain ash. It is absolutely unacceptable to make handles from easily prickly wood: spruce, pine, alder or aspen.
often the handles for locksmith hammers are made of birch wood. For this you will need a small board from which it is necessary to grind the shape of the handle in accordance with the technological card of the locksmith hammer manufacturing, and then sand it well with a construction sandpaper.
If you cut a handle from a thick birch tree branch, it is absolutely essential that you dry it in a warm, well-ventilated and shady place. Do not dry wood with artificial heat sources such as heaters, electric fireplaces or radiators, because the wood will inevitably crack and lose its strength.
If the wooden handle for the locksmith’s hammer will not be dried enough, then it will dry out over time and shrink in volume. And that’s why the head will dangle on it, constantly trying to fly off the handle of the hammer. To make the handle even smoother it is advisable to coat it with a special furniture varnish. That’s it, the handle for the locksmith’s hammer is ready, you can move on to the next step.
Connecting the head to the handle
If the knob is too thick, you should first work its thin end with a rasp, and then with sandpaper. The end of the locksmith hammer handle should finally form a flat cone. Place the head of the locksmith’s hammer on the handle, making sure it is perpendicular to the axis of the handle.
Hold the handle firmly vertically with the head of the hammer up, striking the hard surface from the back wide end downward. The head of the locksmith hammer with each blow slowly but surely fits on the expanding handle, hardening more and more on it. At further blows, the tool head is stationary, indicating that it is firmly “seated” in the handle.
Dislocating the handle of the hammer
There are several methods of making a locksmith hammer, but the most reliable is to use wedges. You can make your own locksmith hammer wedges. Prepare a place for the wooden wedge. So he did not go to the side and did not spoil the handle, make a narrow chisel notch that has a depth of about 5 millimeters, at an angle to the longitudinal axis of the locksmith hammer 30 degrees.
The wooden wedge is a wedge that is about 3 millimeters thick, about 15 millimeters wide, and between 30 and 50 millimeters long. The wedge should taper smoothly towards the front, but the end should be blunted.
After you drive the wooden wedge 15-20 mm into the handle of the mallet, saw off the top part of the handle that protrudes from the head of the hammer with a fine-toothed hacksaw so that it protrudes beyond the head at least 2-3 mm.
Cut the second wedge from a strip of metal of the same shape and size as the wooden wedge, but make it shorter, not more than 20 millimeters long. Take a sheet of iron, which is about half a centimeter thick. Sharpen the wedge on a special machine and hammer it into the handle at the same acute angle to the longitudinal axis of the hammer of 30 degrees, but from the centerline on the other side.
After hammering the metal wedge completely “flush” into the handle of the hammer, the work of making a locksmith’s hammer can be considered over. Then it is worth placing the lock hammer in water for 5 hours to allow the wood to swell. When the wood dries, the locksmith hammer will not wobble anymore.
Using a locksmith’s hammer
To hammer a nail into the board with a nail hammer is not such an easy task, even if it seems so at first sight. If you have made a bad hammer, then under it will break the surface and appear dents, and this is not the most pleasant outcome. To hammer a nail, make sure it goes into the work surface. Finish the job with 2-3 strokes.
The nail must enter at least one-third of the way into the work surface for the joint to be strong. Drive nails at an angle to produce a stiff joint. The board will not split, if the nail will have a diameter no larger than one fourth of its thickness. If you are hammering a nail into a thin board, first bite off the tip with a wire cutter, which can tear and split the wood. It is easier to hammer a nail into wet wood than into dry wood.
When hammering a nail into dry wood, use pliers to keep the middle of the nail from bending as it resists the dry wood. Boards, which are about 10-12 centimeters wide, are fastened with one nail, wide boards are nailed with two nails. If you need to nail several nails, then arrange them in a staggered order in several rows, not in a straight line. A fairly convenient substitute for nailing with human fingers is a wooden clothespin or a narrow strip of paper that is folded in half.
