THE WAY THE Vacuum Pump Works

1. What is the function of the Gas-cooling Vacuum Pumps vacuum pump? What kinds of vacuum pumps are generally found in refineries? The vacuum pump is made to create vacuum pressure in the equipment or container that works below ambient atmospheric pressure or high vacuum. Vacuum pumps frequently used in refineries consist of steam aircraft vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What is the working principle of the steam plane vacuum pump? It consists of a nozzle, a mixing chamber, an expansion chamber, and a pressure store. In operation, drinking water vapor is definitely sprayed from the nozzle in to the mixing chamber at a high speed (1200-1500 m/s). At the moment, a particular negative pressure is generated at the nozzle, to ensure that the pumped gas is definitely flushed into the combining chamber from the gas inlet and blended with drinking water vapor. And get some energy from the drinking water vapor. When the mixed gas stream enters the diffuser chamber, the velocity gradually decreases along the axis, and the pressure steadily boosts along the axis flow until it really is discharged above the atmospheric pressure. Because of the continuous function, the gas in the equipment is constantly 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 higher speed of water vapor, so it gets the characteristics of huge pumping capability, high vacuum, simple produce, convenient set up and maintenance, etc. Currently, the vacuum distillation unit of the refinery The majority of the vacuum pumps utilized are steam plane vacuum pumps.

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