Water ring vacuum pump (referred to as the water ring pump) is a rough vacuum pump, which can obtain the ultimate vacuum of 2000~4000Pa, and the vacuum pump unit vacuum can reach 1~600Pa. Its strengths: The structure is simple, the production accuracy is not high, and the processing is simplified. Compact structure, high pump speed, can be directly connected with the motor, without slow installation. Therefore, with a small structural scale, a large amount of exhaust gas can be obtained, and the air volume is also small. The compressed gas is essentially isothermal, ie, the temperature of the compressed gas process changes little. Because there is no metal friction surface in the pump chamber, there is no need to smooth the discontinuity in the pump and wear is minimal. The seal between the roller and the fastener can be completed directly by the water seal. Inhale evenly, work steadily and reliably, operation is simple, maintenance is convenient. kitchen electric food mixer,electric food mixers,electric food stand mixer Ningbo GOLMA Electric Appliance Co., Ltd. , https://www.golmahome.com
