Q:How about plug wires and cables for power tools?

Class II tools, that is, insulated structures, all double insulated power tools. The specified voltage is over 50V, and the grounding device is not allowed in class II tools. Generally insulated enclosures. Generally speaking, the design of II tools made use of personal protective equipment operator to some reliable method in the tool, the tool has a double protective current, guarantee in the fault state, when the basic insulation failure, insulation and reinforced insulation provided by additional electric shock protection.

Q:How to detect the rotor of power tools?

Rotor spark. 1) the carbon brush and commutator rotor, no free contact. 2) the connection spring on the carbon brush nest is burned, and the person who is burned is not able to connect normally. A vicious circle, sparks plus sparks. Machine failure will also occur.

Q:What's the name of an electric tool for riveting screws into wood? Not understand!

An electric drill can be used! But it can't adjust the torque! There are four types of professional screw twisting tools!

Q:Which is good between pneumatic tools and power tools?

The utility model relates to an electric tool, which is a hand-held or movable mechanical tool, which is driven by an electric motor or an electromagnet, and is driven by a transmission mechanism to operate the working head. Electric tool has the characteristics of portability, simple operation, multiple functions, can greatly reduce labor intensity, improve work efficiency, realize the mechanization of manual operation, which is widely used in building, housing decoration, automobile, machinery, electric power, bridges, gardening and other fields, and poured into the family.

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

You can see the cable plug, the aluminum shell is inserted three I tools, is grounded, the aluminum shell and some II tools, because it has a plastic insulation between the stator and the aluminum shell, so it is the installation of two wire plug.

Q:What devices must be available for all hand held electric tools?

Anti leakage, splash prevention, anti movement, anti overheating

Q:What power tools are used as cage birds?

An electric drill or a small bench drill, drill speed is the best because of the speed change drill, drill hole spacing and easy consumption. If you want to do with special accessories can also change the distribution of wood milling, milling machine, special safety and easy to do.

Q:What are power tools?

There are many kinds of power tools! Hammer, impact drill, electric scissors, electric planer, grinder, plastic welding gun, pistol drill, electric iron, curve sawing machine and so on, there are a lot of marble.

Q:What are the commonly used rotor types for 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.The hammer and drill: used for concrete, brick and building components on drilling, slotting, dehairing. With expansion bolts, installation can improve the speed and quality of pipeline, machine equipment; impact hammer principle is to rely on the internal movement of the piston impact force, impact principle of impact drill is running in gear impact force, so the impact hammer is greater.

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.
