To ensure the normal operation of the machine to extend its useful life, in the use of to strengthen the maintenance work.
1, the machine should be at a temperature of -10 ℃ -60 ℃, relative humidity less than 85%; the surrounding air without corrosive gases, no powder, no explosive dangerous environment work.
2, should regularly check the vacuum pump oil level, regularly add to maintain the oil level in the window 1/2 to 3/4 position; vacuum pump imported 30 or 0 vacuum pump oil for oil.
3, when it is observed that the oil in the pump turns black or white, there is a drop of water in the oil, or the viscosity increases, then the oil is proved to be contaminated and the oil should be replaced immediately. Under normal circumstances every 1-2 months to work continuously replace the oil.
4, with the device in addition to the water device should be based on the moisture content of the package, periodically drain from the rear of the device drainage, drainage and then put on the pipe plug, the general water will automatically decompose, without discharge.
