First, the rotary pump is used to pump the system to 10-2 Pa. The diffusion pump oil is heated and boiled, and the gas molecules in the system are continuously brought to the pump's side arm elbow bulb at a high speed from the ejected oil vapor flow. The working range of the mechanical vacuum pump is reached and is withdrawn, thereby gradually obtaining a high vacuum.
A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physicochemical method to evacuate a pumped container to obtain a vacuum. Vacuum pumps are devices that improve, create, and maintain vacuum in a closed space in a variety of ways. In fact, according to the principle of vacuum pump operation, vacuum pumps can be basically divided into gas trap pumps and gas transfer pumps. Vacuum pump applications include power, petrochemical, pharmaceutical, paper, environmental, metallurgical, food, beverage, electronic coating and other industries.
