Dalan oil pump motor reminds you: in order to ensure the normal operation of the motor, prevent the occurrence of faults, and ensure the safe and reliable operation of the motor, in addition to normal use and maintenance, regular inspections should be carried out to perform maintenance work.
Dalan oil pump motor reminds you: in order to ensure the normal operation of the motor, prevent the occurrence of faults, and ensure the safe and reliable operation of the motor, in addition to normal use and maintenance, regular inspections should be carried out to perform maintenance work. The time interval for regular maintenance can be determined according to the form of the motor and the environment in which it is used.
details as follows:
1, the starting device of the motor
1 It is necessary to clean the external dust in time, wipe the contacts, check the wiring parts for burn marks, and whether the grounding wire is good.
2 Check and clean the motor terminals. Check the junction box wiring screws for looseness and burns.
3 Check each fixed part of the screw, including the anchor screw, end cap screw, bearing cap screw, etc. Tighten the loose nut.
2, inspection of insulation
1 The insulating ability of the insulating material varies depending on the degree of drying, so it is very important to check the drying of the motor windings.
2 The working environment of the motor is humid, corrosive gas in the working room and other factors exist, which will destroy the electrical insulation.
3 Commonly, the winding ground fault, that is, the insulation damage, causes the live part to collide with the metal part that should not be charged, such as the casing.
4 When the motor is in use, always check the insulation resistance, and pay attention to check whether the grounding of the motor casing is reliable.
3, clean the motor
1 Remove dust and sludge from the outside of the motor frame in time. If the use of the environment is more dusty, it is best to clean it once a day.
2 Check the transmission, check the pulley or the coupling for strength and damage, and whether the installation is firm; whether the belt and its coupling buckle are intact.
3 During the operation of the motor, the wear of the carbon brush is an important factor that causes the motor to be scrapped. Therefore, when using the motor, pay attention to the maintenance of the motor carbon brush, that is, periodically replace the new carbon during use. brush.
4 Make sure that the motor cooling fan is clean during the use of the motor.
4, bearing inspection and maintenance
1The bearing should be cleaned after use for a period of time, and the grease or lubricant should be replaced.
2 The cleaning and oil change time should be determined according to the working condition of the motor, the working environment, the degree of cleaning and the type of lubricant. For every 3-6 months of operation, it should be cleaned once and replaced with grease.
3 When the oil temperature is high, or the motor with poor environmental conditions and dust is often cleaned and oil changed.
5, the assembly of the motor
1 When assembling the motor, first remove the hood and fan, then assemble the end cap and the bearing cap bolt with the sleeve wrench, and use the log or copper rod to impact the shaft extension in the axial direction, so that the end cover and the base are separated, and finally take Lower rotor.
2 Explosion-proof motor shall not be assembled casually; when assembling the test, the explosion-proof surface of the part shall not be used as the fulcrum of the crowbar, and it is not allowed to hit or impact the explosion-proof surface.
3 Explosion-proof surface should be placed upwards, and covered with rubber or cloth pad, fastening bolts, spring pads, etc. should not be lost.
4When varnishing and assembling, the insulating paint or dirt attached to the explosion-proof surface should be cleaned, and it should not be scratched with hard objects such as iron sheets, but it can be ground with oil stone.
