Vacuum packaging machines are mainly used in food, pharmaceutical, and daily chemical industries.
In the process of using
vacuum packaging machine , the following common problems are encountered: 1. Low vacuum 2. High noise 3. Vacuum pump injection 4. Vacuum pump oil leakage 5. Vacuum pump oil smoke 6. No heating 7. Heating is not Stop 8. Sealing uneven, not tight or unsealing steel box deformation adjustment steel box 9. While heating, without heating 10. Pump does not pump vacuum 11. Closing cover does not work, etc. 1. Pump oil pollution, too little or too thin Clean the vacuum pump and replace the new vacuum pump oil; the pumping time is too short to extend the pumping time; the suction filter is clogged to clean or replace the exhaust filter; there is a leak, after the pumping, turn off the power, check the solenoid valve, pipe joint, vacuum pump There is no air leakage at the gas valve and the seal around the working chamber.
2. The vacuum pump coupling is worn or broken. The exhaust filter is clogged or the installation position is not correct. Clean or replace the exhaust filter and install it correctly. Check the solenoid valve for leaks and remove it.
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 to remove the oil return valve and cleaned (see the instruction manual for details); after the oil window is loosened and drained, 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 to clean the return valve 6, the heating strip is blown to replace the heating rod; the heating time relay is burned out (starting is Both lights are on at the same time, OMRON lamp color is yellow), replace time relay; add burn and replace and add, and install firmly; control heating temperature band switch bad contact, repair or replace; control heating AC contactor does not reset repair (with airflow Blowing off foreign objects) or replacing; heating transformer bad replacement 7. Heating time relay bad contact or burnout, adjusting time relay to contact or replace with socket; control heating AC contactor not resetting repair or replacement 8, heating time and heating temperature not adjusted Good adjustment to the appropriate; on the heating cloth there are attachments to gently scrape off the attachment with the nail; the pressure solenoid valve does not operate to clean or replace the solenoid valve; the airbag is damaged to replace the airbag; the pressurized gas pipe is damaged repair or replacement; no deflation cooling time The relay is broken (in the electrical box) to replace the time relay; the bleed valve line is broken and found and connected; the deflation valve is stuck or burned out Cleaning or replacement 9. The package bead without heating is short-circuited with the heating device (usually short-circuited with the brazing sheet) to adjust the position of the brazing sheet, or the bagging strip of the bag is closed, and the working chamber is not covered tightly; the motor is tight; Reverse (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, no power to check whether there is power supply; the travel switch does not operate to adjust the travel switch paddle; the fuse is broken (the indicator light is on) Replace the same specification, the insurance is frequently burned, and there is a short circuit to find and eliminate; the motor reverse time is too long, any two-phase power line is replaced and installed (except the ground wire); the oil viscosity is too high, the pump is cleaned and the oil pick-up box has a short circuit.
