How to maintain the vacuum pump of vacuum packaging machine


Vacuum packaging machine can automatic suction the air inside the bag, finishing vacuum sealing process after reaching the preset vacuum , also can blended into nitrogen or other gases, and then complete the sealing process.Vacuum packing machine is often used in food industry, because after vacuum packaging, food antioxidant, so as to achieve the purpose of long-term preservation, vacuum packaging machine include vacuum system, pneumatic system, electrical control system, pneumatic control system, vacuum system is primarily a vacuum pump, vacuum pump mainly include water ring vacuum pump, rotary vane vacuum pump, rotary piston vacuum pump, roots vacuum pump,oil diffusion pump, dry scroll vacuum pump, turbo molecular vacuum pump, and vacuum packing machine is mainly use the rotary vane vacuum pump.

How to maintain the vacuum pump of vacuum packaging machine

1, vacuum pump oil

Vacuum pump operation must keep oil level in the oil window height of 1/2 to 3/4.Should always check the oil level and oil pollution (suggest once a week).

2, replace the vacuum pump oil and oil filter
If oil contaminated and blackened, emulsion or thicken to oil change timely.Oil change at the same time, the oil filter should be changed.And please clean vacuum pump before joining the new oil.

Clean vacuum pump and replace vacuum pump oil steps:

(1) turn off the vacuum pump put away the hot oil.
(2) spin on the drain plug, running 5-10 seconds, put to the best of the oil.
(3) into the cleaning oil to three-quarters of the oil window height.
(4) vacuum pump running 5-10 minutes.
(5) Stop the pump, put away the oil.If oil is let down the turbidity, can not meet the requirements, repeating steps 3 and 4, until the release of oil is transparent.
(6) screw on the drain plug operation for 5-10 seconds.
(7) put all the oil.
(8) Was injected into rules of new oil.

3, change the exhaust filter
If vacuum pump temperature increased significantly, two motor current to achieve or exceed the rated current, pump outlet have lampblack, should check whether the exhaust filter is blocked, such as congestion, should be replaced in a timely manner.Can install at the pump lubrication exhaust pressure gauge, check whether the filter is blocked.When the pressure is greater than 0.6 bar pressure (table) replaceable exhaust filters.

4, cleaning suction filter
Suction strainer shall be kept clean, in order to avoid the pumping speed drop.

5, storage
If the pump not use for a long time, should put all the oil and cleaning the rotary vane vacuum pump,then inject new oil is placed in a dry place.
