According to the air conditioning and refrigeration market was informed that the vacuum pump is generally widely used in low temperature equipment, papermaking machinery, pharmaceutical chemicals, food machinery, industrial furnaces, electronics industry, vacuum equipment, oil, mining, foundation treatment and other fields. How do you know about the vacuum pump repair and maintenance? Xiaobian today for you to expose some of the vacuum pump maintenance tips. 1, always check the oil level position, do not meet the requirements must be adjusted to meet the requirements. With vacuum pump operation, the oil level to the center of the oil standard. 2, the oil change period according to the actual conditions of use and can meet the performance requirements and other considerations, by the user discretion. General new vacuum pump, pumping clean and dry gas, it is recommended to change the oil around 100 hours once. Oil to be seen after the black metal powder, the oil may be extended after the expiration date. 3, regular inspection of oil quality, oil deterioration should be found in a timely manner to replace the new oil, to ensure that the vacuum pump is working properly. 4, under normal circumstances, the vacuum pump should be overhaul after 2000 hours of work, check the aging degree of plastic seal, check whether the exhaust valve cracking, cleaning the valve plate and exhaust valve seat on the dirt. Clean the entire vacuum chamber components, such as the rotor, rotary vane, springs and so on. General use of gasoline cleaning, and drying. After cleaning the rubber parts with a dry cloth can be dry. When cleaning the assembly should be carefully handled and bruised. 5, add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, the lubricating oil should be replaced or replenished in time. 6, check the vacuum pump pipe and joints with loose phenomenon. Rotate the vacuum pump by hand to see if the vacuum pump is flexible. 7, reassembly should be carried out after the trial run, the general shall be empty for 2 hours and change the oil twice, due to cleaning in the vacuum pump will leave a certain amount of volatile, to be functioning properly, and then put into normal work. 8, start the motor, when the vacuum pump is operating normally, open the outlet pressure gauge and import vacuum pump, depending on the appropriate pressure showed, the gradual opening of the valve, while checking the motor load conditions. 9, try to control the vacuum pump flow and head of the range indicated on the sign to ensure that the vacuum pump at maximum efficiency point of operation, in order to get the maximum energy-saving effect. 10, to stop using the vacuum pump, first close the gate valve, pressure gauge, and then stop the motor. 11, the vacuum pump in operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C. 12, vacuum pump in the first month of work, after 100 hours to replace the oil, after each 500 hours, oil change time. 13, often adjust the packing gland, to ensure that the drip filling room is normal (as drops into leakage is appropriate). 14, check the wear and tear of the sleeve regularly, after wear and tear should be promptly replaced. 15, long-term deactivation of the vacuum pump, pump all the necessary open, dry the water, the rotating parts and joints coated with grease installed, safekeeping. 16, the use of vacuum pumps in the winter season, after parking, the lower part of the need to unscrew the drain plug to the media net. Prevent cracking.
