1. Always check the position of the oil level. If it does not meet the requirements, it must be adjusted to meet the requirements. When operating with the hard-toothed residual oil pump, the oil level shall be the center of the oil mark.
2, the oil change period according to the actual conditions of use and whether it can meet the performance requirements, etc., at the discretion of the user. General new hard tooth surface residual oil pump, when pumping clean and dry gas, it is recommended to change the oil after working for about 100 hours. After the black metal powder is not visible in the oil, the oil change period can be extended in the future.
3, often check the oil quality, found that the oil should be replaced in time to replace the new oil, to ensure that the hard tooth surface residual oil pump works properly.
4. Under normal circumstances, the hard tooth surface residual oil pump should be inspected after 2000 hours of operation, check the aging degree of the silicone seal, check whether the exhaust valve piece is cracked, and clean the dirt deposited on the valve piece and the exhaust valve seat. Clean the parts of the entire hard-toothed residual oil pump chamber, such as rotors, rotary vanes, springs, etc. Generally cleaned with gasoline and dried. Botaibang can clean the rubber parts and dry them with a dry cloth. Take care and gently touch it.
5. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the center line of the oil mark. The lubricating oil should be replaced or replenished in time.
6, check the hard tooth surface residue pump pipeline and joints with or without looseness. Turn the hard tooth surface residual oil pump by hand to see if the hard tooth surface residual oil pump is flexible.
7. After re-assembly, it should be tested. Generally, it must be run for 2 hours and oil change twice. Because it will leave a certain amount of volatile matter in the hard-toothed surface residual oil pump after cleaning, it will be put into normal operation after it is running normally.
8. Start the motor. When the hard-toothed residual oil pump is running normally, open the outlet pressure gauge and the imported hard-toothed residual oil pump. After the appropriate pressure is displayed, gradually open the gate valve and check the motor load.
9, try to control the flow and head of the hard-toothed residual oil pump within the range indicated on the sign to ensure that the hard-toothed surface residual oil pump operates at the highest efficiency point to obtain the maximum energy-saving effect.
10. When the hard-toothed residual oil pump is to be stopped, first close the gate valve, pressure gauge, and then stop the motor.
11, the hard tooth surface residual oil pump during operation, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature must not exceed 80C.
12, the hard tooth surface residual oil pump in the first month of work, after 100 hours to change the lubricant, after each 500 hours, change the oil once.
13, often adjust the packing gland to ensure that the drip leakage in the packing chamber is normal (in order to drip out is appropriate).
14, regular inspection of the wear of the bushing, should be replaced in time after the wear is large.
15, the hard tooth surface residual oil pump is long-term use, the pump should be completely dismantled, dry the oil, the rotating parts and joints are coated with grease, and kept safe.
16, when the hard-toothed residual oil pump is used in the cold winter season, after parking, the oil plug screw plug of the lower part of the pump body should be unscrewed to release the medium to prevent freezing cracking.
