Troubleshooting of DZD ~ 400 vacuum packaging machine. The vacuum machine does not exhaust under pressure and cannot open the cover

if the vacuum machine cannot open the cover, it indicates that it has been vented. Only when there is negative pressure after venting, it cannot open the cover. You see, the bulging of the bag is actually the natural reaction of negative pressure to the bag after vacuum. The sound of exhaust after normal vacuum sealing is actually the sound of air intake. But when you see the bag flattened, you think it is exhaust. In fact, it is the reaction after the air pressure in the vacuum chamber reaches the normal pressure

the vacuum cover is sucked and checked from two places:
a. the delay device plug-in is damaged or moved
B. the vent solenoid valve does not work
Troubleshooting: replace the plug-in or delay device, check the control circuit, repair or replace the solenoid valve

this data is from Baidu map, and the final result is subject to the latest data of Baidu map

it should be an exhaust fault. You can open it to check the relevant lines. Qingdao Aixun vacuum packaging machine first applied the liquid crystal control panel in China. The air extraction and deflation time is adjustable and visible, which facilitates the operation and reduces many faults.
