1. What is the function of the Sprial Gear Reducers vacuum pump? What kinds of vacuum pumps are generally used in refineries? The vacuum pump is designed to create a vacuum in the equipment or container that works below ambient atmospheric pressure or high vacuum. Vacuum pumps frequently used in refineries include steam jet vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What’s the working theory of the steam plane vacuum pump? It consists of a nozzle, a blending chamber, an growth chamber, and a pressure outlet. In operation, water vapor is usually sprayed from the nozzle in to the blending chamber at a higher speed (1200-1500 m/s). At the moment, a specific negative pressure is produced at the nozzle, so that the pumped gas can be flushed into the mixing chamber from the gas inlet and blended with water vapor. And get some good energy from the drinking water vapor. When the blended gas stream enters the diffuser chamber, the velocity steadily decreases along the axis, and the pressure gradually boosts along the axis circulation until it really is discharged above the atmospheric pressure. Because of the continuous function, the gas in the equipment is consistently extracted, thus causing vacuum pressure (negative pressure) state in the equipment.

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

4. What is the structure of the water band vacuum pump? What’s the working principle of the water ring vacuum pump? The water ring vacuum pump is composed of a pump casing, an impeller, a water band, a suction chamber, a discharge chamber, and a vent hole.
