7. Cutting machine: it is mainly used to cut aluminum and wood at different angles, and it can be divided into metal material cutting machine and nonmetal material cutting machine. Pay attention to tighten the saw blade and wear goggles when using it.
8. Electric wrenches and electric screwdrivers: Both electric wrenches and electric screwdrivers are used for loading and unloading threaded connectors. The transmission mechanism of electric wrench consists of planetary gear and ball spiral groove impact mechanism. The electric screwdriver adopts jaw clutch transmission mechanism or gear transmission mechanism.
9. Concrete vibrator: used for tamping concrete when pouring concrete foundation and reinforced concrete members. Among them, the high-frequency disturbing force of electric direct-connected vibrator is formed by the motor driving the eccentric block to rotate, and the motor is powered by 15Hz or 2Hz intermediate frequency power supply.
1. Electric planer: used for planing wood or wooden structures, and can also be used as a small planer when mounted on a bench. The cutter shaft of the planer is driven by the motor shaft through the belt.
11. Marble machine: generally, stone is cut, and dry or wet cutting can be selected. Common saw blades include dry saw blade, wet saw blade and wet and dry saw blade. Jiezhuang is used to cut wall and floor tiles.
the difference between electric tools and pneumatic tools. electric tools are tools that use low-power motors or electromagnets as power and drive the working head through the transmission mechanism.
what is the difference between p>PK and pneumatic tools? Pneumatic tools are mainly tools that use compressed air to drive a pneumatic motor and output kinetic energy to work.
PK result 1. Working ability: Both of them provide many different working modes, but the speed adjustment and output power adjustment of pneumatic tools are simple, and they are smaller and lighter under the same output power. In addition, the pneumatic tool can provide more choices in the speed range, and there is no fever or overload fault. When the overload occurs, the starting tool only stops rotating, and once the overload phenomenon is relieved, it will resume normal operation.
2. Environmental adaptability: In terms of environmental application ability, pneumatic tools have stronger water resistance. Although soaking in water is harmful to tools, it is not as harmful as electric tools with hardware. Moreover, because the pneumatic tool can use the internal combustion engine air pump, it can adapt to various bad or harsh environments.
3. Economy: In terms of economic performance, the initial investment of electric tools is less, but the long-term use of energy consumption is higher, and the cost of tool maintenance and replacement is also higher. The initial investment of pneumatic tools requires the establishment of pneumatic pipeline equipment, but the long-term use is low in energy consumption and tool maintenance.
selection and purchase of power tools 1. usage: distinguish between household and professional tools according to needs, because most power tools are designed for professionals, and you should distinguish between professional and general household tools when purchasing. Usually, the difference between professional tools and general household tools is in power. The professional tools have higher power, and the general household input power does not need to be large.
2. Appearance: the pattern of the outer package is clear and undamaged, the plastic box is firm, and the buckle is firm and durable. The appearance of the tool is uniform in color, with no obvious shadow, dent, scratch or bump on the surface of plastic parts, assembly dislocation between shell parts ≤.5mm, smooth coating on aluminum castings and no oil stain on the surface of the whole machine. When held by hand, the handle of the switch is flat, and the length of the cable is generally not less than 2 meters.
3. nameplate parameters: qualified products with "3C" certification should be selected, and nameplate parameters of electric tools should be consistent with those on CCC certificate. The detailed address and contact information of the manufacturer and factory should be on the tool manual. The nameplate or certificate should have the traceable batch number of the product.
4. Convenience: A compact and highly integrated electric tool will undoubtedly be more convenient to use than a large and single-function product. It is recommended that you compare related products horizontally when purchasing household electric tools, and try to choose electric tools with rich functions, small size, simple structure and easy storage.
5. Safety: Hold the tool by hand, turn on the power supply and operate the switch frequently to make the tool start frequently, and observe whether the on-off function of the tool switch is reliable. At the same time, observe whether there is any abnormality in the TV and fluorescent lamp at the scene. So as to confirm whether the tool is equipped with an effective radio interference suppressor.
6. Vibration and sparks: when the tool is powered on for one minute, hold it by hand during operation. The hand should not feel any abnormal vibration obviously. Observe the commutation sparks, which should not exceed 3/2 level. Generally, when looking in from the air inlet of the tool, there should be no obvious arc on the commutator surface.
7. Noise: Most household electric tools will produce certain noise when used, but there are also high and low levels of noise when used. It is suggested (especially for families with children and the elderly) to try out the household electric tools to see if the noise of the electric tools is within the acceptable range.
Precautions for the use of electric tools Food 1. Class II products should be selected in general occasions, and Class II or III products should be selected in damp places or places with good electrical conductivity such as metal frames. Class III products should be selected in narrow places such as metal containers, pipelines and boilers. If Class I products are used, other necessary safety measures shall be taken according to safety requirements.
2. Before use, carefully check it, the appearance is free from damage, the switch action is flexible without jamming, and the power lead and the shell of the power tool should be in good condition. The insulation resistance between winding and shell measured by 5V megohmmeter shall not be less than .5 megohmmeter. Hand-held power tools with metal shell should have reliable protective grounding wire.
3. The power socket must match the power plug of the electric tool, and keep the equipment away from rain and humid environment. When using electric tools outdoors, use an extended power cord that is allowed to be used outdoors, and keep the power cord away from heat sources, oil stains, sharp edges or moving tool parts. The operating switch should be placed within the reach of the operator.
4. Take personal protective equipment and wear appropriate clothes according to the form and characteristics of electric tools. Before opening the electric tool, remove the adjusting screwdriver or wrench and move it away. During use, strictly observe the relevant safety operation regulations, connect and use it correctly, do not overload, stay awake, concentrate and operate the electric tool rationally.
