When we talk about vacuum pump, we have to mention rotary vane vacuum pump. Rotary vane pump is composed of pump body, rotor, rotary vane, end cover, spring, etc. So, do you know how to use it? Today, I’d like to show you how to use rotary vane vacuum pump. Rotary-vane vacuum pump is low, i...

Liquid Ring Vacuum Pump were originally used as self-priming pumps. It is composed of impeller, pump body, suction and exhaust disc, water ring, suction port, exhaust port and auxiliary exhaust valve formed by water in the pump body wall. In many industrial production process, such as vacuum filt...

1. working principle of pneumatic valve: The pneumatic valve is set for the removal of condensable gas by rotary vane vacuum pump. Usually the gas removed by the pump is a mixture of permanent gas and condensable gas. In the process of compression and exhaust, when the partial pressure of condens...
