The reason for the low vacuum degree: Pump oil pollution, too little or dilution; the pumping time is too short; the treatment of gas filter plugging: Cleaning the vacuum pump, replacing the vacuum pump oil; cleaning or replacing the exhaust gas filter

Second, the cause of big noise faults: the vacuum pump coupling wear or rupture; the exhaust filter is blocked or the installation position is not positive; there is leakage treatment method: replacing the vacuum pump; cleaning or changing the exhaust filter and installing correctly; check whether the solenoid valve has leak and exclude

Three, vacuum pump oil spray failure reason: suction valve 0-type ring shedding; spin chip abrasion treatment method: Unplug the vacuum tube on the pump nozzle, remove the suction nozzle, remove the pressure spring and suction valve, gently stretch the O-ring several times, and then embed it in the groove, and then reinstall it;

IV. Cause of oil leakage of vacuum pump: plug valve in return to oil window loosening treatment method: Remove the return valve, wash, remove oil window, wrap up with raw material or thin plastic film.

Fifth, vacuum pump lampblack fault Reason: suction filter plugging or pollution; pump oil pollution; Plug treatment method of return valve: cleaning or replacing the exhaust filter; replacing the new oil; cleaning the return valve

6. No heating failure reason: heating strip burn; heating time relay burn off; hot-line burn-off, heating transformer bad treatment method: Replacing the heater, with the hot line, and installing firmly; replace the heating transformer

7, non-discharge gas failure reason: cooling time relay bad; the vent valve line short circuit; The method of sticking or burnout treatment: replacing the time relay; locating and connecting; removing the cleaning or replacing
