Vacuum oil purifiers may need to operate uninterruptedly for a long time, or even a few years for maintenance, such as large nuclear power plants, power plants, steel production lines, etc. However, the downtime of the general oil filter is relatively long, and in many cases it may not be used for a long time. The interval between two uses may be several months before starting up. So at this time we must pay attention to the precautions for the shutdown of the oil filter. This is directly related to the service life and operating performance of the oil filter.
The order of first shutdown is: first turn off the heater (remember that this must be the first to turn off), if you do not turn off the heater first, it may lead to idle heating, which will cause the machine to burn out, and even cause dangerous accidents such as leakage. Second, after turning off the heater, we need to continue to keep the vacuum pump and oil pump running. If the machine is shut down directly under high oil temperature, the high temperature oil may adversely affect the seals. When the oil cools below 50 degrees, turn off the vacuum pump and oil pump, and open the pressure relief valve on the vacuum tank to release the vacuum. Due to the low internal pressure, it may not be possible to remove the oil inside the machine. When removing the oil in the tank, we can take reasonable use of the oil pump and the opening and closing of the ball valves to effectively remove the remaining oil inside the machine. At the same time, we need to note that if the machine is not used for a long time, the oil inside the machine must be completely drained. So that it can be started smoothly next time, and will not pollute the nature of the oil next time.
At the same time, we need to pay attention to the maintenance of the machine during shutdown:
1. After a long time of use, we need to pay attention to check whether the electrical equipment and wiring have burned black, and if found, solve the problem in time.
2. After long-term use, we need to replace the vacuum pump oil in the vacuum pump regularly.
3. Clean the filter element before it is not used regularly or for a long time to prevent impurities from hardening and coking and blocking the filter element.
4. The water condensed by the condenser must be drained out every time to prevent water from corroding the body.
The above are the precautions for the shutdown of the oil filter, which is an important means for us to ensure the life and normal use of the machine.
