1. Pump oil pollution, too little or too thin to clean the vacuum pump, replace the new vacuum pump oil; pumping time is too short to extend the pumping time; pumping filter plugging cleaning or replacing the exhaust filter; there is a leak, close after pumping Power supply, check the solenoid valve, pipe joint, vacuum pump suction valve and the seal around the working chamber for leaks.
2. The vacuum pump coupling is worn or broken and replaced; the exhaust filter is clogged or the installation position is not correct, the exhaust filter is cleaned or replaced and installed correctly; if there is a leak, check whether the solenoid valve is leaking and removed.
3. The suction valve O-ring is removed and the vacuum tube on the pump nozzle is removed. The suction nozzle is removed, the compression spring and the suction valve are taken out, and the O-ring is gently stretched several times to re-insert it into the groove. It can be installed; the rotary vane wears and replaces the rotary vane.
4. The oil return valve is blocked. Remove the oil return valve and clean it (see the instruction manual for details); when the oil window is loose, after draining the oil, remove the oil window and wrap the raw material tape or thin plastic film.
5. The suction filter is clogged or contaminated to clean or replace the exhaust filter; the pump oil is contaminated to replace the new oil; the return valve is blocked. The cleaning return valve
6. The heating strip is blown to replace the heating strip; the heating time relay is burnt out (the two lamps are on at the same time, the OMRON lamp is yellow), the time relay is replaced; the heating wire is blown to replace the heating wire, and the installation is firm; the heating temperature band is controlled. Poor contact, repair or replacement of the switch; control of the heated AC contactor without reset repair (blowing foreign matter with airflow) or replacement; heating transformer bad replacement
7. Heating time relay bad contact or burnout, adjust time relay to contact or replace with socket; control heating AC contactor does not reset repair or replace
8. The heating time and heating temperature are not adjusted and adjusted to be suitable; the attached cloth on the heating cloth is gently scraped off with the nails; the pressure solenoid valve does not operate to clean or replace the solenoid valve; the airbag is damaged to replace the airbag; the pressurized air tube is damaged. Repair or replacement; no bleed cooling time relay is bad (in the electrical box) Replace time relay; bleed valve line open circuit find and connect; vent valve stick or burn out remove cleaning or replacement
9. The package bead without heating is short-circuited with the heating device (usually short-circuited with the brazing sheet). Adjust the position of the brazing sheet, or rest the bagging strip.
10. The studio is not covered. The studio is tightly closed; the motor is reversed (be careful not to change the ground wire, the color line is the ground wire); the fuse is broken (the indicator light is on) Replace the same specification insurance
11. There is no power supply to check whether there is power supply; the travel switch does not work to adjust the travel switch dial; the fuse is broken (the indicator light is on) Replace the same specification, the insurance is frequently burned, there is a short circuit to find and eliminate; the motor reverse time is too long, any two-phase power cord Exchange installation (except ground wire); oil viscosity is too high, clean the pump and change the oil in the fuse box, there is a short circuit repair
