How to use vacuum cooling tank 

For example , the 20-110mm pe pipe vacuum cooking tank

You need to first check whether the water is coming out of the vacuum pump and whether there is any air leakage.

Water pump and filter drains need to be closed with valves

It is necessary to ensure that water comes out of the vacuum pump system before starting vacuuming

There is a flange in the middle of the water tank that needs to be blocked, and there is a partition between the two vacuum sections of the water tank that needs to be blocked with rubber skin and flange, otherwise the vacuum cannot be sucked up.

Check the working status of the vacuum pump

The first step is to close all drain valves. The second step is to fill the water tank with water. The third step is to find sealing objects at both ends of the water tank. The fourth step is to turn on the water pump and vacuum pump. Open the white transparent water supply pipe valve in front of the vacuum pump to 1/2. Then measure the vacuum degree of the water tank and see if the pressure gauge displays between 0.1 and 0.7mpa.
