Q:The torch is smoking, but what's wrong with it?

Flashlight in the normal use of smoke in the process of generalization, there are four reasons:First, the electric drill made of aluminum wire is used for too long and the temperature is too high;Two is an electric drill, the load is too heavy, the current is too large;Three is the electric drill forced air-cooled, poor airflow;Four is the electric drill, the motor winding has the breakdown,

Q:How does electric drill rotor stator friction generate heat?

If there is no friction at the beginning, the following procedure shall be taken:1. Two check the position of the bearing shell, if worn or damaged, such as, basic machine.2. No, please note that when friction occurs in the engine, there is no such phenomenon in the refrigerator. The rotor needs replacing.3. Check for loose wire problems.

Q:When you play an electric drill, how do you know if there is any steel bar in the wall?

Bosch detectors can be used to detect, in general, reinforced concrete walls, block walls at most, in the middle of a steel bar.

Q:Hold the electric drill, turn to the right direction, turn the drill down, up, backward, turn left

You take the screws off the handle, and that's where the wires are out of contact

Q:Electric hammer drill chuck dismantling method

Due to the rotation of the drill bit in the hammer also produced a rapid reciprocating motion along the direction of the drill rod (frequent impact), so it can be fast drilling on the brittleness of cement concrete and stone material. You can use high-grade hammer switch, the electric hammer drill in different working condition, only rotation is not only the impact of shocks, both impact and rotation can not rotate.

Q:How to change the electric drill to positive reversal?

Impact drill: the impact mechanism of impact drill with ball type two and type. A ball impact electric drill consists of a moving plate, a fixed plate, a steel ball and so on. Brake disc is connected with a main shaft through threads, and with 12 balls; fixing by pins fixed on a casing, and a 4 ball, in the role of thrust, 12 ball 4 ball rolling along, the hard alloy bit to produce rotary impact motion, can drill a hole in the brick, brick, concrete and other brittle materials. The utility model can make the fixed disk rotate with the moving disk without impacting, and can be used as an ordinary electric drill.3. (hammer): hammer drill holes in any material, the most widely used.

Q:You need to punch holes in the wall and hang the picture. How do you use the drill?

Bits in the drill bit may be wooden drills, not hard enoughWhen drilling, the drill bit clamps vertically into the wall, the movement will be relatively big, all rightThe size of the drill is marked on the handle of the drill

Q:Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug. Listen to the teacher, the father said, as if the earth will leak

In recent years, leakage protection performance and the reliability greatly, has become a standard power supply, reliability of human protection over ground protection to a certain extent, but the impact of grounding protection and leakage protection to human body protection, so many hand-held electric tools to cancel the earthing protection, relying instead on leakage protector. And use the two eye plug.Look at the instructions for the hand-held power tools with two plugs. All require that the power supply be equipped with an electric leakage protector.

Q:Stainless steel plate drilling, with drill + twist drill, drilling what skills?

Hello, I am a maintenance worker for the food factory. I drill at no more than a few hundred tons of stainless steel on 2mm per month. Here are some tips for drilling stainless steel! 1, if the hole is larger than 6mm, use the 3.2mm-4mm drill to drill holes, and then drill the big bit. 2, find a nail or sharp object and leave a hole in the center of the drill. 3, the electric drill chuck must clamp the twist drill bit, the twist drill short is better, the edge of the twist drill does not need to be too sharp, too sharp. 4, drill speed should be 80-120 the best effect, the bigger the speed drill down, drill out, stainless steel plate behind the return, don't think the drilling. 5, stabilize the site, uniform force, point electric drill. 6 bit, do not eat, then don't hesitate, quickly remove it, usually a new drill drill can not simply stainless steel, we get a new bit, is the first mill, then drill! 7, I wish you a pleasant drilling.

Q:Hammer and hammer which is good, general household, expansion bolts installed in the wall of the hole

A good bit of impact drill can replace the hammer with a hammer, but can not replace the impact drill. Time for cutting concrete like hammer, not rotary drilling.
