If the equipment is frequently damaged, it will affect its service life, so the daily maintenance of the series motor of the high-pressure cleaner must be in place.
1. Cleaning the series motor of the high pressure washer: timely remove the dust and sludge outside the frame of the series motor of the high pressure washer. If the environment is dusty, clean it once a day.
2. Daily inspection of series motor of high pressure washer: check the connection terminals of series motor of high pressure washer. Check whether the terminal box wiring screws are burnt or loose; check the screws of each fixed part and tighten the loose nuts; check whether the transmission device, pulley or coupling is bold or damaged, and whether the belt and its coupling buckle are intact.
3. High-pressure cleaner series-excited motor starting equipment: clean the external dust in time, wipe the contacts, check whether there are burn marks on each wiring part, and whether the grounding wire is good.
4. Inspection and maintenance of the bearings of the series-excited motor of the high-pressure cleaner: the bearings should be cleaned after a period of use, and the grease or lubricating oil should be replaced. The time for cleaning and oil change depends on the working conditions of the motor, working environment, cleanliness, and the type of lubricant. It should be cleaned every 3-6 months and the grease should be changed again. When the oil temperature is high, or the motor with poor environmental conditions and more dust, clean and change the oil frequently.
5. Check the insulation of the series-excited motor of the high-pressure cleaner. The insulating ability of insulating materials varies with the degree of dryness. The presence of factors such as humid working environment of the motor and corrosive gas in the working room will destroy the electrical insulation. The common ground fault is the winding ground fault, which causes the live part to collide with the metal part that should not be live, such as the case. This kind of fault not only affects the normal operation of the motor, but also endangers personal safety. Therefore, in the use of the series motor of the high-pressure cleaner, the insulation resistance should be checked frequently, and attention should be paid to whether the grounding of the motor casing is reliable.
6. Annual repair of series-excited motor of high-pressure cleaner: conduct a thorough and comprehensive inspection and maintenance of the motor, add missing and worn components of the motor, completely eliminate dust and dirt inside and outside the motor, check the insulation, clean the bearing and check its Wear conditions. Find problems and deal with them in time.
