1, the motor starting equipment, to timely clean the external dust, dirt, wipe the contact, check whether the wiring parts have burn marks, grounding wire is good.
2, check, clean the motor terminal. Check whether the wiring screws of the junction box are loose.
3. Check each fixed part of the screw and tighten the loose nut.
4. Clean the motor. Clean the dust and oil pollution outside the motor frame in time. If the environment is dusty, clean it once a day.
5, the insulation capacity of the insulation material varies according to the degree of dryness, so it is very important to check the drying of the motor winding. The presence of factors such as damp working environment and corrosive gases in the working room will destroy the motor insulation. Common is winding grounding fault, that is, insulation damage, sh.en.hua... 22 Make the charged part and the shell and other metal parts that should not be charged, such a failure will not only affect the normal operation of the motor, but also endanger the person. Therefore, the motor in use, should often check the insulation resistance, but also pay attention to check the motor housing grounding is reliable.
6. Check the transmission device, check whether the pulley or coupling is broken or damaged, and whether the installation is firm; Whether the belt and its coupling buckle are in good condition.
7, the maintenance of the motor's carbon brush, in the operation of the motor, the wear of the carbon brush is a very important factor leading to the scrap of the motor, so pay attention to the maintenance of the motor's carbon brush when using the motor, that is to say, in the process of use to regularly replace the new carbon brush, so that in the process of use can be more smooth.
8, bearing inspection and maintenance. Bearings should be cleaned and replaced with grease or lubricating oil after use for a period of time. The time of cleaning and oil change should be determined by the working condition of the motor, the working environment, the degree of cleanliness, and the type of lubricant, generally every 3-6 months, it should be cleaned once and replaced with grease. When the oil temperature is high, or the motor with poor environmental conditions and more dust should be cleaned and oil changed frequently.
9, in the operation of the motor, there is often a problem that the motor makes a strange sound, mainly the cooling fan, in the process of use due to the timely cleaning of the dust above the cooling fan, resulting in the abnormal operation of the motor in the process of operation, so in the process of using the motor to ensure that the motor's cooling fan is clean.
10, in order to avoid rust on the explosion-proof surface, oil or 204-1 replacement type anti-rust oil should be applied on the explosion-proof surface.
11. When assembling the motor, the wind cover and fan should be taken first, and the bolts of the end cover and bearing cover should be manually assembled with the sleeve plate. Then, the log or copper rod should be extended along the axial impact shaft to make the end cover and the frame leave and the rotor should be removed. Remove the parts, the explosion-proof surface should be placed upward, and covered with rubber or cloth padding, fastening bolts, spring pads, etc., carefully do not lose.
12. When dipping and assembling, the insulating paint or dirt attached to the explosion-proof surface should be cleaned, and hard objects such as iron sheets should not be scratched, but uneven places can be ground with a whetstone.
