Hit car glasses for escaping Safety Hammer

Q:Is the motor of an electric tool the alternating current motor or the direct current motor?: The series motor is usually used. The series motor is connected in series because the stator and rotor windings are connected together, so when the current is reversed, the magnetic field is reversed, so the torque direction remains the same. However, according to this principle, the motor works at 180 degrees after the torque is gone, so even the AC motor, but also need to reverse, in order to work like a DC motor.The rectifier also needs to be rectified if it is operated under the direct current. The rectifier bridge is very small. On the circuit board, there are four diodes close together, mostly rectifier bridge

Q:What safety problems should we pay attention to when using electric drills or hand-held power tools?: The motor inlet shall be provided with a ground or zero connection device.(4) wearing shoes must be worn while wearing protective gloves such as insulating gloves.(5) each use of tools must be strictly checked.

Q:How are hand powered tools classified into class I, class II, class III?: Simple methods are: hand-held electric tools for metal shell for class I. The plastic case is of the type ii. Class III uses safe voltage.

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: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 other tools are there for the furniture except the pistol hole?: It is mainly used in construction, decoration, furniture industry, opening for objects or objects in the past, also known as hammer in some industries.Well, there are more drilling tools on the market now.

Q:What are the common rotors of power tools?: 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.Concrete vibrator: used for pouring concrete foundation and reinforced concrete members, tamping concrete to eliminate air holes and increase strength. The high-frequency disturbing power of the electric direct acting vibrator is driven by an electric motor to rotate the eccentric block, and the motor is powered by an 150Hz or 200Hz intermediate frequency power supply.The planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive.Electric tools commonly used bearing type: 606, 607, 608, 626, 627, 628, 629, 6000, 6001, 6003, 6004, 6200, 6201, 6202, 6203, 6303, 61907, 688 commonly used carbon brush models: 50#, 408#, 43#, 44#, 303#, 21#, 6M etc.

Q:What material does the power tool housing fit?: The hammer and drill: used for concrete, brick and building components on drilling, slotting, dehairing. Combined with expansion bolt, various pipelines can be improvedInstallation speed and quality of machine tools.Concrete vibrator: used for pouring concrete foundation and reinforced concrete members, tamping concrete to eliminate air holes and increase strength. Among them, electric straightThe high frequency disturbing force of the combined vibrator is driven by the motor to rotate the eccentric block, and the motor is powered by 150Hz or 200Hz intermediate frequency power supply.The planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive

Q:Compared to pneumatic tools, what are the advantages of electric tools?: The pneumatic tool is more environment-friendly, energy-saving, and has better environmental adaptability, and is safer than an electric tool. The pneumatic tool has the advantages of simple structure, convenient operation, long service life and convenient maintenance

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
