Q:Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug

In recent years, leakage protection performance and the reliability greatly, has become a standard power supply, reliability of human protection over ground protection to a certain extent, but the impact of grounding protection and leakage protection to human body protection, so many hand-held electric tools to cancel the earthing protection, relying instead on leakage protector. And use the two eye plug.Look at the instructions for the hand-held power tools with two plugs. All require that the power supply be equipped with an electric leakage protector.

Q:What other tools are there for the furniture except the pistol hole?

As we all know, a hand drill is an AC power supply or a DC battery powered drilling tool. It is a kind of hand held power tool.

Q:Is there an electric tool for screwing bolts? It's bolts, not screws

The 2 floor is good! Electric wrenches, pneumatic wrenches, front with prominent slot, you can clamp different sleeve, find the corresponding sleeve with buckle...

Q:What kind of power tools are hand drills? 1, 2 or 3?

I class: in the prevention of electric shock protection, in addition to relying on basic insulation, but also the need for zero protection.Class II: the tool itself has double insulation or insulation without the need to protect the ground.Class III: Powered by a secure, ultra low voltage power supply, no voltage higher than the safety supply voltage is generated within the tool.The above is the classification of insulation categories.

Q:What are the common rotors of power tools?

Electric drill: the main specifications are 4, 6, 8, 10, 16, 19, 23, 25, 32, 38, 13, 49mm and so on. Figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. The electric screwdriver adopts the embedded clutch, transmission mechanism or gear drive mechanism. The specifications include M1, M2, M3, M4, M6 and so on.

Q:What's the difference between a flashlight and an electric screwdriver?

As the mechanical component, the electric screw driver can work without the electric batch power supply, and the batch power supply provides the energy and the related control function for the electric screwdriver. Drive the motor. Since the parameters of the motor are different, the speed will be different when the power of the batch power supply is the same.

Q:Is the motor of an electric tool the alternating current motor or the direct current motor?

The motor of a general electric tool is an alternating current motor.

Q:Is BOSCH's power tools good or MAKITA's power tools?

MAKITA electric tool features:The utility model has the advantages of small noise, strong power, good performance, long service life, light body, strong and durable, easy operation and convenient repair. The utility model is the necessary high-quality product for professional personnel or amateur DIY personnel.

Q:What is the working principle of power tools?

AC motor, AC motor of induction motor, its strong induction current (eddy current) magnetic field generated in the rotation of the magnetic force on the rotor copper bar, continuous cutting, according to Lenz's law, the induced current has the effect of relative motion occurs against the rotor magnetic field and the rotor is, with the magnetic field and rotation. But the rotor rotation speed of the high speed magnetic field does not transform, otherwise it will not be able to cut the copper lines.

Q:Is Li Xiang power tool good?

I was doing a power tool, you said this is a good point, I suggest you buy brand electric tools, East into a really good, but you buy when I suggest you go to the East into the store to buy if to go to other places to buy will be expensive, and not necessarily the East into true. There are a lot of imitation in East into sell, buy electric tools as long as buy a good brand of machine authentication
