20mm Electric Hammer

Q: How are hand powered tools classified into class I, class II, class III?: Class I protection against shock of the product depends not only on the basic insulation of the equipment, but also on additional safety precautions. The method is to connect the electrically conductive parts that may be touched with the protective wires in the installed stationary lines so that the accessible, electrically conductive parts are not electrified in the event of basic insulation damage. Such products are: hand-held power tools, mobile daily appliances, mobile mechanical and electrical equipment.

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: How are the I, II, and III classes of power tools classified?: The popular point is that:The 1 type of tool is metal housing with ground wire.The 2 type of tool is the insulated housing.The 3 type is low voltageOfficial point of explanation can be searched for power tool category ~!

Q: What is the working principle of power tools?: A direct current motor called a direct current motor. Due to the magnetic field circuit and armature circuit of the different links, can be divided into series motor, motor, compound motor;

Q: Power tools are power tools?: Divided into electric, pneumatic, gasoline tools, currently on the market these 3 main types. I've been a tool for over 10 years

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 kind of material does the power tool case have?: In 1895, the German overtone produced the world's first direct current drill. The outer shell is made of cast iron and can drill holes in the steel plate 4mm. Then there was a three-phase power frequency (50Hz) electric drill, but the motor speed failed to break through the 3000r/min. In 1914, there was a single-phase electric motor driven by a series of exciting motors, and the motor speed was over 10000r/min. In 1927, the power supply frequency of intermediate frequency electric tool 150~200Hz, it not only has the advantages of high speed single-phase series motor, and has the advantages of simple structure, reliable three-phase motor, but because the need if current supply is limited.

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: What material does the power tool housing fit?: Electric drill: the main specifications are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm and so on. The figures refer to the steel whose tensile strength is 390N/mmThe maximum diameter of a drill drilled on a material. 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. An electric screwdriver adopts a clutch, a transmission mechanism, or a gear drive mechanismThere are M1, M2, M3, M4, M6 and so on.

Q: What are power tools?: Electric tools divided into many categories: hammer drilling, grinding, sawing, cutting, assembling, charging, cutting and so on, each class has a lot of varieties.
