How The Vacuum Pump Works

1. What is the China Air Compressors function of the vacuum pump? What kinds of vacuum pumps are commonly found in refineries? The vacuum pump is designed to create a vacuum in the equipment or container that functions below ambient atmospheric pressure or high vacuum. Vacuum pumps commonly used in refineries consist of steam plane vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What is the working theory of the steam aircraft vacuum pump? It consists of a nozzle, a combining chamber, an growth chamber, and a pressure store. In operation, water vapor is sprayed from the nozzle into the combining chamber at a higher speed (1200-1500 m/s). At this time, a particular negative pressure is produced at the nozzle, to ensure that the pumped gas is flushed into the combining chamber from the gas inlet and blended with water vapor. And get some energy from the water vapor. When the combined gas stream enters the diffuser chamber, the velocity steadily decreases along the axis, and the pressure steadily raises along the axis stream until it really is discharged above the atmospheric pressure. Because of the continuous work, the gas in the equipment is constantly extracted, thus causing vacuum pressure (negative pressure) state in the equipment.

3. What are the characteristics of the steam aircraft vacuum pump? The steam jet vacuum pump entrains the pumped gas at a high speed of drinking water vapor, so it has the characteristics of huge pumping capability, high vacuum, simple manufacture, convenient installation and maintenance, etc. Currently, the vacuum distillation device of the refinery The majority of the vacuum pumps utilized are steam aircraft vacuum pumps.

4. What is the structure of the water ring vacuum pump? What is the working theory of the water ring vacuum pump? The water ring vacuum pump comprises a pump casing, an impeller, a water ring, a suction chamber, a discharge chamber, and a vent hole.
