Working principle:
The working chamber is a confined space connected to a vacuum pump and pressure sensor via a vacuum line. The vacuum pump continuously works to extract the gas in the working chamber, and the pressure in the working chamber will be less and less than the standard atmospheric pressure. The intake air is fed through the intake valve to balance with the pumping to obtain the required vacuum. A hand valve is installed in the front stage of the vacuum pump to manually adjust the pumping capacity of the vacuum pump. The vacuum pump is equipped with a gas ballast valve. When the pump is used to pump steam, make sure the gas ballast valve is open.
