Electric drills, as a common product among power tools, are widely used in multiple fields such as home decoration, industrial production, and auto repair. However, many users often neglect the daily maintenance of electric drills when using them. This not only affects the service life of the electric drill but may also lead to potential safety hazards. This article will provide a detailed introduction to the maintenance knowledge of electric drills, helping you better maintain and care for them and extend their service life.
First, the importance of electric drill maintenance
During the operation of an electric drill, due to the need for ventilation and heat dissipation, dust is prone to accumulate inside. These dusts will cause the lubricating oil on gears and bearings to mix, deteriorate and dry up, accelerating wear. Therefore, regular cleaning and maintenance of the electric drill can not only improve its rotational accuracy but also reduce excessive clearance caused by bearing wear, thereby extending the service life of the electric drill.
Second, specific methods for the maintenance of electric drills
(1) Cleanliness
Regular dust cleaning: After using an electric drill, the dust inside it should be cleaned regularly. A clean vacuum cleaner or soft-bristled brush can be used for cleaning to prevent dust accumulation from affecting the performance of the electric drill.
Clean the rotor and commutator: Loosen the casing of the electric drill, remove the rotor, and sand the commutator on the rotor with sandpaper to remove dirt and oxide layers.
Clean the bearings: Inspect the bearings before and after the rotor. If the bearings are well sealed, only the surface needs to be cleaned. If the seal is damaged, the bearing should be replaced in time.
(2) Lubrication
Add grease: After cleaning the interior of the electric drill, an appropriate amount of grease should be added between the gear pair and the bearings. It is recommended to use greases of brands such as "Mobil" or "Shell".
Regularly change the lubricating oil: According to the usage frequency of the electric drill, regularly change the lubricating oil to ensure the lubrication effect inside the electric drill.
(3) Inspection and Replacement
Check the carbon brushes: Regularly inspect the wear of the carbon brushes. If the carbon brushes are shorter than 7-8 millimeters, replace them with new ones in a timely manner.
Check the wires: Inspect the wires of the electric drill for any damage or aging. If so, replace them in time.
(4) Storage
Dry environment: Electric drills should be stored in a dry and well-ventilated place to avoid moisture and corrosion.
Avoid collision: When storing the electric drill, avoid collision or dropping to prevent damage to the internal structure of the electric drill.
Third, precautions for the maintenance of electric drills
(1) Pre-operation inspection
Check all components: Before using the electric drill, it is necessary to check whether all components are intact to ensure operational safety.
Check the circuit lines: Ensure that the circuit lines are intact, without any damage or aging.
(2) Precautions during operation
Avoid prolonged operation: During the use of the electric drill, it should be avoided to run continuously for a long time to prevent overheating.
Maintain standardized operation: When operating an electric drill, it is necessary to maintain standardization, ensure that the electric drill operates at a constant frequency, and avoid danger.
(3) Maintenance after operation
Unplug the power cord in time: After the operation is completed, the power cord of the electric drill should be unplugged in time to reduce the danger caused by the short circuit of the electric drill.
Regularly inspect the motor and controller: Regularly check the motor, controller and leakage circuit breaker to ensure the normal operation of the electric drill.
Fourth, Summary
The maintenance of electric drills is the key to ensuring their efficient operation and extending their service life. Regular cleaning, lubrication, inspection and replacement, as well as paying attention to the storage environment and operation norms, can effectively reduce the wear and failure rate of electric drills.
