Customers who have used the vacuum packaging machine know that the core component of the vacuum packaging machine is the vacuum pump, which plays a very important role in the vacuum pumping function of the vacuum packaging machine. However, if the vacuum pump failure, for the entire food vacuum packaging machine equipment, the vacuum work can not be completed. So if the vacuum pump has a small fault, how should the staff carry out the correct maintenance.

1、 The vacuum pump of vacuum packaging machine does not work or has serious noise, which may be caused by the following reasons:

1. Solution: check the incoming line of power supply or replace the fuse core.

2. Vacuum pump reversal, solution: power supply commutation.

3. IC main contact point poor contact, solution: adjustment or replacement.

4. ISJ normally closed contact bad, solution: adjust or replace.

5. Vacuum pump time-out does not stop, the reason is ISJ does not work, solution: maintenance or replacement.

2、 The reasons for not reaching the specified limit vacuum degree are as follows:

1. Vacuum pump oil too little or pollution, solution: add oil or change oil.

2. Solution: clean the vacuum pump, replace the exhaust filter, and check the check valve.

3. Solution: check the gas path and eliminate the leakage.

4. 2DT iron core is stuck and does not reset. Solution: maintenance or cleaning.

3、 There may be the following reasons for insufficient or no vacuum in vacuum packaging machine:

1. Air leakage of packing bag, solution: replace the packing bag.

2. There is no vacuum in the heat seal gas chamber during vacuum. Solution: 1dt doesn't work, and maintenance is eliminated.

3. 1dt iron core on the sealing gasket or magnetic cover seal ring leakage, solution: maintenance or replacement.

4、 The reasons for no heat seal may be as follows:

1. Nickel chromium skin burned, solution: replace.

2. The heat seal circuit is loose and open circuit. Solution: tighten and re connect.

3. 2C main contact bad contact, solution: adjust or replace.

4. 2C does not work. Solution: check whether 1sj normally open and 2sj normally closed contacts are in good condition.

5、 The reasons for insufficient sealing strength are as follows:

1. Temperature time adjustment is too low, too short, solution: readjustment.

2. Vacuum time adjustment is too short, solution: readjust to make it ≤ -0.08mbra.

3. The heat seal gas chamber is broken, the solution is to replace it.

The above is a small collection of vacuum packaging machine vacuum pump does not work some of the situation and how to solve, there is the vacuum packaging machine work may encounter problems and solutions.
