Vacuum packaging machine fault analysis

Double chamber vacuum packaging machine has the advantages of superior function, convenient maintenance, easy operation and wide application. Today, mainly for the introduction of the causes of vacuum packaging machine failure and solutions. 1. The vacuum pump does not move, the possible reasons are as follows: The travel switch is not pressed, please close the cover. Adjust the travel switch, electric cover open type, please adjust the lever. Vacuum pump time relay damaged, please replace. The vacuum pump motor is damaged, replaced or repaired. 2. The vacuum chamber can not reach the vacuum degree for the following reasons: The vacuum pump is worn or damaged and can not reach the vacuum level. The trachea is loose, the tube is ruptured, the seal of the straight chamber is damaged, the solenoid valve is damaged, and so on, causing the air to flee into the vacuum chamber. Vacuum pump oil is not enough. Pumping time is not enough. 3. The vacuum chamber can not be opened, the possible reasons are as follows: The deflation solenoid valve fails to open. Electric cover opener may damage the cover motor, rod stuck. 4 processing after the bag left the air, may have been like the original Bu :.. Sealing Article reset is not good, due to exhaust bag when the mouth pressure died. Can not be out of the bag of air. The sealing bead is not flexible, the bag mouth crushed, resulting in air can not be extracted. 5 abnormal sound when operating, tripping, exhaust black smoke, dripping oil. Blocking the air inlet, there are foreign objects in the pump. Vacuum pump oil is not enough, or use non - standard oil due. Long-term operation of the pump and its overheating, or running at high temperatures, please keep the machine ventilated and heat. Long-term use leads to the aging of the stand-alone pump motor, the aging of the solenoid valve of the vacuum pump, leading to the degradation of the insulation performance, and the like. Please replace the parts or contact the manufacturer Heat seal failure 1. Can not seal, the possible reasons are as follows: Heat seal switch not selected, the heating power is not turned on. Heating element damaged. Heating element power connection disconnected. Heating time set to 0. Heating time relay damaged. The closing solenoid valve does not move, the airbag does not bulge (or the airbag is damaged). 2. The sealing pattern is uneven. The air bubbles and the sealing are not strong. The reasons are as follows: The sealing tape is not clean enough and there is foreign matter. Heating time or temperature is too low. Airbag inflation is not enough, leading to seal pressure is not tight. Cooling time is not enough, causing shrinking bubbles. The heating strip is damaged. The surface is not smooth enough.
