1, start the motor, when the vacuum pump is operating normally, open the outlet pressure gauge and import vacuum pump, depending on their display of the appropriate pressure, and gradually open the gate valve, while checking the motor Load conditions. 2, the vacuum pump in operation, the bearing temperature can not exceed the ambient temperature 35. 3, 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. 4, 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. 5, 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 the 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. 6, the same conditions in the tube to clean up, to ensure smooth piping. 7, try to control the vacuum pump flow and head of the range indicated on the sign to ensure that the vacuum pump in the highest efficiency point of operation, in order to get the maximum energy-saving effect. 8, reassembly should be carried out after the trial run, usually to be empty for 2 hours and oil change twice, because cleaning will leave a certain amount of volatile in the vacuum pump, to be functioning properly, then put into normal work. 9, check the vacuum pump pipe and joints with loose phenomenon. Rotate the vacuum pump by hand to see if the vacuum pump is flexible. 10, vacuum pump in the first month of work, after 100 hours to replace the oil, after each 500 hours, oil change time. 11, often adjust the packing gland to ensure normal drip filling room indoor (as a drop of leakage is appropriate). 12, add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, lubricating oil should be replaced or replenished promptly. 13, unscrew the vacuum pump head diversion plug, pouring diversion (or cited pulp). 14, close the outlet valve and outlet pressure gauge and import vacuum gauge. 15, move the motor, try to see whether the motor steering is correct. 16, check the wear and tear of the sleeve on a regular basis, after wear and tear should be promptly replaced. 17, the use of vacuum pumps in the winter season, after parking, the lower part of the need to unscrew the drain screw to release the media net. Prevent cracking. 18, long-term deactivation of the vacuum pump, the pump should be all open, dry the water, the rotating parts and joints coated with grease installed, safekeeping. 19, if there is an abnormal sound vacuum pump should stop immediately check the reasons. 20, to stop using the vacuum pump, first close the gate valve, pressure gauge, and then stop the motor. 21, 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. (Vacuum oven vacuum pump maintenance)
