A vacuum pump is a power equipment for evaporators, and its stable operation is related to the working status of the entire evaporation system. Therefore, how to maintain the vacuum pump during the operation of the evaporation equipment? It is important to pay attention to the maintenance and upkeep of vacuum pumps, extend their service life, and improve their efficiency. The maintenance methods for vacuum pumps are also crucial.
What maintenance methods do we need to use for vacuum pumps in daily use? Share the maintenance methods for vacuum pumps with everyone. The daily maintenance and upkeep methods of vacuum pumps are generally divided into two types: regular routine maintenance and maintenance methods during use. The following are specific maintenance methods, which can be briefly understood by everyone.
1, Regular maintenance methods for vacuum pumps
1. Regularly check the oil level position, and adjust it to meet the requirements if it does not meet the requirements. Ensure that the oil level reaches the center of the oil mark when the vacuum pump is running.
2. Regularly check the oil quality, and if the oil deteriorates, replace it with new oil in a timely manner to ensure the normal operation of the vacuum pump.
3. Regularly inspect the vacuum pump pipeline and joints for any looseness. Rotate the vacuum pump by hand and see if it is flexible. And check the wear of the shaft sleeve. If there is significant wear, it should be replaced in a timely manner.
4. The oil change period for vacuum pumps should be considered based on actual usage and whether they can meet performance requirements. Generally, for new vacuum pumps, it is recommended to change the oil every 100 hours of operation. After the black metal powder is not visible in the oil, the oil change period can be appropriately extended in the future.
5. In general, after 2000 hours of operation, a vacuum pump needs to be repaired to check the aging degree of the rubber seal, check whether the exhaust valve plate is cracked, and clean any dirt that has settled on the valve plate and exhaust valve seat. Clean the rotor, rotor, spring, etc. in the entire vacuum pump chamber with gasoline, and dry them. For rubber parts, clean them and wipe them dry with a dry cloth. When cleaning and assembling, be sure to handle it gently and be careful not to damage it.
2, Usage and maintenance methods for vacuum pumps
1. The maintenance method for the vacuum pump during operation is that the bearing temperature of the vacuum pump should not be higher than the ambient temperature by 35 ℃.
2. The maintenance method for vacuum pumps in the cold winter season should pay attention to antifreeze during use. After parking, unscrew the drain plug at the bottom of the pump body to drain the medium completely. Prevent frost cracking.
3. When the vacuum pump needs to be stopped, the gate valve and pressure gauge should be closed first, and then the motor should be stopped to reduce the damage caused by sudden power outage.
4. If the vacuum pump is not used for a long time, it is necessary to dismantle all the pumps, dry the water, apply grease to the rotating parts and joints, and store them properly.
5. After reassembling the vacuum pump, a trial run should be carried out. Generally, it needs to run empty for 2 hours and change the oil twice, as there will be a certain amount of volatile substances left in the vacuum pump during cleaning. After normal operation, it can be put into normal operation.
The above is the maintenance method for vacuum pumps, hoping to be helpful to everyone.
