THE WAY THE Vacuum Pump Works

1. What is the function of the vacuum pump? What kinds of vacuum pumps are generally used in refineries? The vacuum pump is made to create a vacuum in the equipment or container that functions below ambient atmospheric pressure or high vacuum. Vacuum pumps generally used in refineries consist of steam aircraft vacuum pumps, water band vacuum pumps and reciprocating vacuum pumps.

2. What’s the working basic principle of the steam aircraft vacuum pump? It contains a nozzle, a blending chamber, an growth chamber, and a pressure outlet. In operation, water vapor is certainly sprayed from the nozzle in to the blending chamber at a high speed (1200-1500 m/s). At the moment, a particular negative pressure is generated at the nozzle, so that the pumped gas is certainly flushed into the blending chamber from the gas inlet and mixed with water vapor. And get some energy from the drinking water vapor. When the combined gas stream enters the diffuser chamber, the velocity steadily decreases along the axis, and the pressure steadily boosts along the axis circulation until it really is discharged above the atmospheric pressure. Because of the continuous work, the gas in the gear is continually extracted, thus causing vacuum pressure (negative pressure) state within the equipment.

3. What are the features 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 large pumping capability, high vacuum, simple produce, convenient set up and maintenance, etc. Presently, the vacuum distillation device of the refinery The majority of the vacuum pumps used are steam plane vacuum pumps.

4. What is the Gas-cooling Vacuum Pumps structure of the water ring vacuum pump? What is the working basic 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.
