1. Low vacuum: Cause of the problem: the pump oil is polluted, too little or diluted; the pumping time is too short; the suction filter is clogged. Treatment method: clean the vacuum pump, replace the vacuum pump oil; extend the pumping time; clean or replace the exhaust filter
2. The cause of noise is large: the vacuum pump coupling is worn or broken; the exhaust filter is blocked or the installation position is not correct; there is a leaking treatment method: replace the vacuum pump; clean or change the exhaust filter and install it correctly; check whether the solenoid valve is Have air leaks and exclude
3. Vacuum pump injection failure Cause: The suction valve 0-ring is off; the rotary vane wear treatment method: unplug the vacuum tube on the pump nozzle, remove the suction nozzle, take out the compression spring and the suction valve, and gently pull the O-type Loop a few times, re-insert it into the groove, then install it; change the rotating piece
4. Vacuum pump oil leakage Fault reason: oil return valve is blocked; oil window is loose. Treatment method: remove the oil return valve, clean; after draining oil, remove the oil window, wrap the raw material tape or thin plastic film
5. Vacuum pump soot fault Cause: The suction filter is clogged or contaminated; the pump oil is contaminated; the return valve is blocked. Treatment method: cleaning or replacing the exhaust filter; replacing the new oil; cleaning the return valve
6. No heating Cause: The heating strip is blown; the heating time relay is burnt out; the heating wire is blown, the heating transformer is broken. Treatment method: replace the heater; replace the heating wire and install it firmly; replace the heating transformer
7. Do not deflate. Cause: The cooling time relay is bad; the bleed valve line is short-circuited; the bleed valve is stuck or burned. Treatment method: replace the time relay; find and connect; remove the cleaning or replace
8. Bubble bag Failure reason: the pressure valve is broken or blocked; the pressurized gas path is not smooth at the same time. Treatment method: replace or clean the pressure valve; smooth out the pressure and pressure.
