Do you know how to change the oil of a double-chamber vacuum packing machine?

I know that the main component of the vacuum packing machine is the vacuum pump. If the vacuum pump is short of oil, it will affect the operation of the vacuum packing machine. Therefore, we must change the oil of the vacuum pump in time to ensure that the vacuum packing machine can operate normally. So do you know how to change the oil of the vacuum pump?

The tools that need to be prepared for the first choice of oil change are: wrenches, vacuum pump oil (mostly No. 100 vacuum pump oil, depending on the corresponding mark on the vacuum pump label), and container.

The specific steps are as follows: 1. Open the casing and find the vacuum pump. 2. Place the pre-prepared container under the oil drain hole (for those without oil drain hole, we need to remove the housing fixing bolts of the vacuum pump and the double-chamber vacuum packaging machine, and take out the pump to prevent the oil from entering the housing ) 3. Use a wrench to remove the bolt of the oil drain hole. After removal, the oil in the vacuum pump will flow out. After the flow is exhausted, re-tighten the bolt. 4. Use a wrench to open the bolt of the oil filling hole of the vacuum pump. 5. Put the pre-prepared vacuum pump oil into the vacuum pump through the oil filling hole. 6. When the vacuum packing machine vacuum pump oil to be added reaches the position indicated in the above figure (usually at the half position of the oil level display line), stop refueling, and then tighten the refueling hole bolt to complete the oil change operation.
