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

Each of these devices has a "back" logo indicating double insulation protection, and the double insulated layer forms insulation protection between the outer shell and the inner part of the tool, thereby preventing the occurrence of electric shock. So no three plug in,

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:How about plug wires and cables for power tools?

Class I tools are common type power tools with a rated voltage of over 50 volts. Class I tools not only rely on basic insulation but also include an additional safety measure in the protection against electric shock. The method is that the accessible conductive parts and protection has been installed in the fixed line in the (ground) wire together, make accessible conductive parts in the basic insulation does not become damaged in the charged body. Plug for three pin plug type tool.

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

If the factory is assembled, use an electric screwdriver! Only suitable for twisting small screws! Because the torque itself is not large! Like you twist it on a wood, use a Zigong drill, or a rechargeable drill! Because of these two belts with adjustable torque! Unlike an electric drill, it always turns that way! This torque is automatically separated by reaching a certain torque! If you screw a big screw, it's an electric wrench!

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:Which is good between pneumatic tools and power tools?

Pneumatic tools are the mainstream trend, pneumatic tools more suitable for long time work, rather than power tools, permanent fever, and even burned out the internal parts, pneumatic tools can be seen more secure. Power tools initial investment is low, but long-term use of energy consumption is higher, and tool maintenance and replacement costs are higher, and pneumatic tools more environmentally friendly, long-term use cost is much lower than the electric.

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:Compared to pneumatic tools, what are the advantages of electric tools?

Compared with electric tools, pneumatic tools have the advantages of light weight, large output, little trouble, easy operation, convenient maintenance and little maintenance.

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

A flashlight is a drilling tool powered by alternating current or direct current batteries. It is a hand-held electric tool.The main components of a drill are a drill chuck, an output shaft, a gear, a rotor, a stator, a casing, a switch and a cable.Electric torch (pistol drill) -- a tool used for drilling metal, wood, plastics, etc.. When equipped with positive and negative reverse switch and electronic speed regulating device, it can be used as electric screwdriver. Some models are equipped with rechargeable batteries, which can work normally within a certain period of time without external power supply.

Q:What is the working principle of power tools?

An electric motor that rotates by alternating current is called an alternating current motor. There are many kinds, mainly:A, the series excitation motor - rectifier DC generator for AC motor, namely into this kind of motor, at the same time shift due to alternating current in the magnetic field and the armature circuit, therefore, the direction of the torque constant remains unchanged, the machine is kept turning. This kind of motor can also be used as AC and DC, so it is also called universal motor". Vacuum cleaner, sewing machine and other household appliances, etc..B, an induction motor -- a device that rotates the rotor in the rotating magnetic field and causes the rotor to rotate due to the action of eddy currents. Rotating magnetic field is not caused by mechanical method, but by alternating electric flux in the number of electromagnets, so that the magnetic properties of the cycle of change, can be seen as a rotating magnetic field. Usually three-phase induction motor (with three pairs of magnetic poles) is used. The motion of the DC motor is just the opposite of the direct current generator. In the generator, the induced current is formed by the induced electromotive force, so they are in the same direction. In an electric motor, the current is supplied by an external power supply, and the direction of the induced electromotive force is in opposition to the armature current I.C and synchronous motor - the motor with the armature from one pole to the second pole, just the same as the current that turns into the current. This kind of motor cannot start on its own and must be operated by another motor or special auxiliary winding so that the proper frequency can be reached before it can be switched on. If the load changes and the speed changes, the speed is not in line with the AC frequency, so that the pace of disturbance, tend to stop or cause damage. Due to restrictions, it is not widely used.
