- Q: How the first electric screwdriver
- 1, according to the need to distinguish between home or professional use, most power tools are designed for professionals, when shopping, should distinguish between professional and general family tools. Usually the professional and general household tools in different power, large power tools for professional use, to facilitate professionals to reduce the workload, the general household tools because the project is small, the workload is relatively small, so the input power tools need not be huge.2. The outer packing of the tool should be clearly patterned and not damaged. The plastic case is firm and the plastic case should be firmly and durable.3, the appearance of the tool should be uniform color, no obvious effect of plastic wire surface and dent, no scratch or bump traces, assembling dislocation between parts of 0.5mm shell, aluminum casting coating is smooth and beautiful without defects, the surface shall be free from dirt and stains. When holding by hand, the handle of switch should be smooth. The length of cable should be no less than 2 meters.4, the tool nameplate parameters should be consistent with the CCC certificate. The instructions should have detailed address and contact information of the manufacturer and the manufacturer. The nameplate or certificate shall have a batch number traceable to the product.5. Hold the tool by hand, switch on the power supply, operate the switch frequently, make the tool start frequently, and observe whether the switch of the tool switch is reliable or not. At the same time to observe the scene of TV sets, fluorescent lamps are abnormal. To verify that the tool is equipped with a valid radio interference suppressor.
- Q: What is the torque requirement of a household electric tool motor?
- Because I want to choose a high-end motor, with electric tools, electric motor is very expensive, at least have to more than 2000, good 50 thousand, but little noise, asked the motor manufacturers, he said that when the actual work is it has a torsion index, because the power is not the way to quota, but is the torque it can be. For example, how large saw blades can carry saws, and how long and thick wood can be sawed. However, this kind of motor is generally not used by woodworking, and is mostly used by precision equipment. I can't just try to play with such expensive things.
- Q: What type of motor is used in electric tools?
- The speed regulating motor is composed of a taper driving wheel and a pressure plate, pressed by a set of disc springs, and the input shaft is connected with the driving wheel by a key to form a pressing active device. A group of tapered planetary friction wheel inside between the driving wheel and the pressing plate, lateral sandwiched between the taper ring and fixed speed cam, and friction; when the compression of the active device operation, the friction wheel to do pure rolling, the fixed cam ring and the governor does not move, so the friction wheel in the rotation for public transport, through the planetary friction wheel central shaft and a slider driven by planetary gear bearing rotation.
- Q: What is the cause of the burning of electric motor tools?
- (1) the installation and maintenance of motor, mistakenly triangle motor winding connection with Y connection, or mistakenly Y connection with the triangle. (2) winding phase, inter turn short circuit or earthing lead to winding current increase and unbalanced three-phase current, which makes motor overheating. (3) pole group coil connecting each phase coil number of incorrect or uneven distribution, resulting in the no-load current of three-phase unbalance, and the current is too large; when the motor is running the three-phase current imbalance, noise and vibration, motor overheating. (4) the stator and rotor become friction heated. (5) the cage rotor of induction motor is broken or the winding rotor winding is broken. The motor output is insufficient and overheated. (6) motor bearing overheating.
- Q: In decorating power tools, can the cutter for cutting tiles be used for cutting boards and grooving on walls?
- As long as the tool head will do, cut tiles, concrete and other commonly used alloy cutting pieces, cut wood, with serrated slices, cut steel and other metal, usually with a grinding wheel.Cutting machine this thing brand is not very important, buy a quality check not much, also one hundred and fifty dollars or so.
- Q: The insulation resistance of two kinds of hand-held power tools is not less than
- Insulation resistance is the most basic insulation index of electrical equipment and electrical circuit. For the handover test of low voltage electrical equipment, the insulation resistance of the motor, the distribution equipment and the distribution line shall not be lower than 0.5M at ambient temperature (for the running equipment and circuit, the insulation resistance shall not be lower than 1M /kV).
- Q: How does the power tool gear select the lubricant?
- Mainly depends on the nature of the work. Gear with high speed movement should be made of a large penetration grease (softer) to reduce resistance; and a kind of impact grease, such as impact drill, should be made of a small penetration grease (stiffer). Gear large and high speed places, when the temperature is high, it is easy to throw out the grease, to choose high temperature and penetration of the small, small gear, small gap, the use of needle penetration, and so on
- Q: What tools are needed for motor maintenance?
- If the motor is checked, the meter, shake meter (DC resistance measurement, interphase insulation, ground insulation, etc.) will be used
- Q: How are power tools assembled?
- Electrical accessories (full) wrench, multimeter (clip), hammer, screwdriver, sandpaper
- Q: What power tools are used to make holes in ceramic tiles?
- First use a glass drill to blow through the tile (pistol drill will do), and then hit the drill bit to hit the wall (must impact drilling).
