Tag: water ring vacuum pump

The working principle of water ring vacuum pump is to use water as the sealing medium to generate vacuum by rotating the water ring. Specifically, the main parts of water ring vacuum pump include pump body, water ring, impeller, inlet and outlet. When the water ring in the pump body rotates, a closed space is formed between the water ring and the pump body, and the gas at the inlet port is sucked into the inside of the water ring, and with the rotation of the water ring, the gas is compressed and discharged from the pump body. Due to the fast rotation speed of the water ring, the residence time of the gas inside the water ring is very short, so the water ring vacuum pump can produce a high vacuum degree.

The water ring vacuum pump is equipped with an eccentric rotor with fixed vanes, which is a rotary variable volume vacuum pump that throws water (liquid) to the stator wall, the water (liquid) forms a liquid ring concentric with the stator, and the liquid ring and the rotor vanes together constitute a variable volume.
