The hand drill is smoking, but there is still something wrong

The eating bag line inside the motor burned.

The main thing is the aging of the rubber ring on the piston and the hammer, the large cylinder is erected, the mouth is facing down, if the hammer can fall freely, the rubber ring must be aging, the aging of the rubber ring can hear the sound of the piston and the hammer hitting each other when working, after dismantling the machine, you can find that the end face of the piston and the hammer is shiny, and the impact seed is short and can also cause no impact (can be compared with the new impact seed) without oil may also cause impact weakness.

If the above conditions are normal and there is no impact, then you must observe the large cylinder to see if there are cracks, and those with cracks need to be replaced. If the motor rotates after starting, the hammer head turns and the sound of compression cannot be heard, it may be that the connecting rod is broken or the eccentric wheel is broken.

Precautions for the use of electric drills:

1. Check whether the power cord is damaged before use. If so, it must be wrapped with insulating tape, and should not be soaked in water and trampled indiscriminately during use, and should not touch heat sources and corrosive media.

2. For the hand drill with metal shell, it must be protected and grounded.

zero) measures.

3. Before use, confirm that the hand drill switch is in the off state to prevent the plug from being plugged into the power socket.

When the electric drill suddenly turns.

4. The electric drill should be idling before use, and check whether the transmission part is flexible, whether there is abnormal noise, whether the screws are loose, and whether the sparks of the commutator are normal.

There are four reasons why the hand drill smokes during normal use:

First, the electric drill wound with aluminum wire has been used for too long and the temperature is too high;

Second, the load of the electric drill is too heavy and the current is too large;

the third is that the forced air and cold airflow of the electric drill is not smooth;

Fourth, the winding of the electric drill motor is faulty, the first two situations cause smoke, and it is stopped in time after the smoke is found, and it can continue to be used after cooling, and the latter two cases must be found out and repaired before they can be used.

The smoke of the hand drill is still rotating and the speed is not reduced, indicating that the problem is not very big, the probability of belonging to the first three situations is larger, if it is rotating but the speed is significantly reduced, it must be a motor failure, which needs to be repaired.

It's best to take it apart and take a look at it first. It should be a short circuit in the stator. The rotational speed will drop significantly. Take it to the repair shop, and you can get it for a few dozen quick bucks.

Summary. Hello dear, it's a pleasure to serve you. The hand drill smoked, but it also turned the reason: 1The hand drill is smoking, because the current is too high, causing the plastic wire on it to smoke due to the high temperature.

Hello dear, it's a pleasure to serve you. The hand drill smoked, but it also turned the reason: 1The hand drill is smoking, because the plastic liquid on it is not lifted due to the excessive current, and the temperature is too high and the smoke is smoking.

2.It didn't stop because there was no good protection on it. For example, temperature control sensors or electric rubber segments or flash flash detection. It shows that your hand drill lacks protection measures.

3.So it's just a plastic thread, and the temperature leakage is too high and it smokes. The hail has not yet formed a short circuit or open circuit. In this case, the hand drill can work normally, which is a normal phenomenon.

Personal advice if the hand drill is already smoking. Don't use it anymore. It's dangerous.

Is there a problem with the motor of the electric drill, it may be a problem with the brushes, or the coil is short-circuited.

A hand drill is a drilling tool powered by AC power or DC batteries, and is a kind of hand-held power tool.

Hand drill structure.

Hand drill is the largest selling product in the power tool industry, widely used in construction, decoration, pan-furniture and other industries, used to make holes in objects or penetrate objects, and some industries are also called electric hammers.

The main components of the hand drill: drill chuck, output shaft, gear, rotor, stator, casing, switch and cable.

Hand drills (pistol drills) – tools used to drill holes in metal materials, wood, plastic, etc. When equipped with a forward and reverse switch and an electronic speed control device, it can be used as an electric screwdriver. Some models are equipped with rechargeable batteries, which can work normally for a certain period of time without an external power supply.

Special models: Right angle drills --- suitable for use in confined workspaces. (The head of the drill is 90 degrees to the fuselage, and the required working space is reduced.) ）

First of all, please make sure that your electric drill is plugged in and that the power supply is working properly. If there is no problem with the power supply, it may be caused by the failure of the drill itself.

Second, check that the drill bit is installed correctly and that it is aligned with the drilling position. If the drill bit is not installed correctly or is not aligned with the drilling position, the drill will be very difficult to turn and may get stuck or burn out.

Finally, check the mechanical parts of the drill for damage or aging. If there is a failure in the mechanical part of the drill, such as gear damage, bearing aging, etc., it will also cause the drill to not work properly.

To sum up, if your drill is difficult to turn and smokes, it is recommended to send the drill to a professional repair shop for repair.

The most likely place to fail when buying a hardware hand drill is mainly its motor and armature winding.

1. Motor repair.

1. Performance: After power-on, the motor does not respond, resulting in the failure of the hand drill to operate normally;

Solution: If the motor cannot operate normally, the body of the electric drill should be disassembled to see if the fuse is blown or the power cord is blown out, if there is such a problem, the fuse or power cord should be replaced immediately; It is also possible that the armature winding or stator winding is damaged, which has to be replaced or repaired; It is also possible that the bearing is rusty, and the shaft should be covered with lubricating oil or derusted.

2. Performance: The motor rotates slower and slower, resulting in the reduction of the impact force of the hand drill and the inability to operate normally.

Solution: Brushes should be replaced immediately due to severe and slow wear and tear.

3. Performance: The noise of the motor is too loud when operating, and the electric drill cannot help trembling.

Solution: Due to the wear of brushes or bearings, the brushes and bearings have to be replaced.

2. Repair of armature windings.

The armature winding is a properly important component in the hand drill, and its damage will cause the hand drill to not be able to perform normal operation. Common faults include short circuits and open circuits in armature windings.

1. Short circuit of armature winding: due to the damage of the insulating surface layer of the adjacent coil in the coil of the armature winding, the coil cannot be energized, and then the normal operation is affected. Therefore, when it is found that the coil is damaged or the surface insulation material of the wire turn is damaged, we should replace the coil in time to maintain the normal operation of the armature winding.

2. Armature winding circuit break: can be detected with an all-round measuring table, if the resistance value between the two commutators is greater than the normal parameters, then there must be a broken circuit between the coils between the two commutators, and the coils between them should be replaced immediately.

These are the analysis of the problem of repairing the hand drill and its brief repair method, I hope it can be helpful to you. Thank you!

You can see if it's sweeping the hall, or the rotor grinding the stator. Or maybe the rotor is pregnant.
