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).

Q:Is power driven tools power tools?: It is a necessary tool, is the direct driving power, such as a hammer, drill, etc..Second, the power tools do not distinguish between DC and AC, so the charging type is also an electric tool.Third, the air pump is an electric tool, but the tool fittings, such as the spray gun and the pneumatic wrench, belong to the pneumatic tool.

Q:What power tools are available for air conditioning? Quick drilling: Since water is added, there must be mud leaking when drilling, which can cause walls to be dirty and difficult to clean up. There is also a method of drilling without water. The disadvantage is that the drill wears very much.

Q:What's the function of the capacitor in the power tools?: You don't ask very clearly, I think you ask the capacitor is the starting capacitorAC electric tools to turn up, you need a rotating magnetic field, while the individual current single-phase motor can not form the rotating magnetic field, so the need for a starting capacitor to phase to phase current, the two winding of the generated nearly 90 Eve joy difference, to produce a rotating magnetic field. Household fans, for example

Q:Know the power tool type and how to find the corresponding carbon brush: We are mainly based on speed, current density, size and commutator performanceWe choose carbon brushes by experimenting with a lot of carbon brushes, and then record them and choose the ones that best meet the requirementsDifferent carbon brushes have different characteristicsSome special wear, no-load long endurance timeYes, especially for spark controlYes, especially good for EMCAnd so on, at present, I basically can only rely on the experiment and experience, as if there is no other good way.

Q:What brand of power tools are better?: Ken, all kinds of electric tools are good, I recommend you a sign. Shen shen. The quality has nothing to say. The price is not very expensive. Now the production of hammer. Drill, grinder. Cutting machine, 7 inch, 9 inch. The quality is exceptionally good. I'm selling well, and I hope to adopt it. There's still a lot to ask me. I did the repairs, too

Q:Why use helical gears for power tools?: Minimum number of tooth bevel gear undercutting is not standard spur gear less, therefore, the helical gear drive can achieve a more compact body.

Q:Are the metal housings of the two types of power tools grounded?: Generally speaking, the design of II tools made use of personal protective equipment operator to some reliable method in the tool, the tool has a double protective current, guarantee in the fault state, when the basic insulation failure, insulation and reinforced insulation provided by additional electric shock protection.

Q:Grease for electric tools: Color lighter, indicating a temperature resistance is not good, there is resistance to extreme pressure and shear resistance and other properties are not good.

Q:The difference between a power cell and an energy storage battery and an electric tool battery: Power battery mainly includes lead-acid battery, Ni Cd battery, Ni MH battery and lithium battery four kinds.Lead acid battery (VRLA), the electrode is mainly made of lead and its oxide, and electrolyte is a kind of accumulator of sulfuric acid solution. It is the main power battery in the market at present, but it is not recognized by the market because of its high pollution, large volume and heavy weight.
