Q:How does the power tool gear select the lubricant?
Lubricating oil is used in all types of vehicles, machinery and equipment in order to reduce friction, protection machinery and processing of liquid or semi solid lubricant, lubrication, cooling, mainly to rust, cleaning, sealing and buffering effect.
Q:What is the cause of the burning of electric motor tools?
The direct cause of motor burnout is high temperature.The common fault of motor is divided into mechanical fault and electrical failure in two categories, including: electrical fault of stator and rotor winding short circuit, open circuit, and start the equipment failure; mechanical failure including: excessive vibration, overheating of bearing, the stator and rotor friction and abnormal noise.
Q:How are power tools assembled?
If the new motor coil wrapped back, to observe whether qualified cover whether can cover, there is no breakage phenomenon, using a multimeter to measure resistance balance is grounded, if not balanced or grounding coil can be usedRemove the insulation paint left in the stator and remove rust from the rotorReady can be installed, Bahrain slowly turn the rotor to see if there is no card feeling, if there is a hammer at the end cover fixed nut OK good agreement, remember the Bahrain check whether the grounding resistance is the balance of three-phase
Q:What power tools are used to make holes in ceramic tiles?
If the tiles are homogeneous and of relatively high hardness, the ideal is to use an inlaid alloy drill bit (also a glass drill) and a multi-function electric drill. The first is the use of surface rotation function, after the surface would have to be careful, even with a hammer hammer function with rotary hammer through the high hardness of the ceramic tile; at the same time to water (usually plastic Coke bottles, bottle through a small hole can be cooling, high hardness) or ceramic tile will make alloy annealed alloy embedded bit on a rotating and lose the hardness of scrap.
Q:How to distinguish between true and false vicese electric tools
Vicese the authenticity of the product from the following two methods to identify:1, security code inquiriesVicese each of the products are displayed on the fuselage anti-counterfeit labels, scratch coating security encoding only, the user can directly call the security code query on the phone to check the authenticity according to the voice prompts;2, look at the outer packingThe packaging of vicese generous, small products commonly used colored kraft paper packaging boxes, packaging boxes exquisite; molding box plus plus cowhide box set. Packaging cottage and rough, poor printing quality, the basic can be determined not genuine;
Q:What are the motors that are often used in hand held electric tools?
Most power tools are series excited motors with an electric brush inside.The motor has the characteristics of small size, high power and high speed.But it can not work for a long time, and some can be controlled by thyristor.
Q:Why should the power tools be powered off when the people leave?
Mainly for the safety of production, to prevent accidents.
Q:What power tools are used in electric stone carving tools and engraving inscriptions?
Electric carving machine for carving art equipment, including miniature electric carving machine, small electric engraving machine, the whole cast iron structure of small electric engraving machine, bed after aging treatment, eliminate stress by rolling stone nuts of double ball screw, ensure the operation precision, and has the characteristics of high rigidity, high precision, high efficiency, stable operation, no noise. Electric engraving machine is the wood, stone, MDF and other materials engraving operations, applicable to process production, toys, handicrafts industry, decoration and furniture industry, flooring, wall panels, building materials and other industries.
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:In decorating power tools, can the cutter for cutting tiles be used for cutting boards and grooving on walls?
General family use, then buy more than 100 units, you can, because the amount of small, so buy 110 models can do, cut or buy, buy, then buy large manufacturers. Jiangsu East and strong factory production license can definitely Shijia. These two are 180 yuan. You can look at the price on the Internet first. I operate electric tools, absolutely. Cut the board and the wall as long as you change the saw blade
