THE WAY THE Vacuum Pump Works

1. What is the function of the vacuum pump? What types of vacuum pumps are commonly found in refineries? The vacuum pump is designed to create a vacuum in the gear or container that works below ambient atmospheric pressure or high vacuum. Vacuum pumps typically used in refineries consist of steam aircraft vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What’s the working basic principle of the steam plane vacuum pump? It consists of a nozzle, a mixing chamber, an expansion chamber, and a pressure wall plug. In operation, water vapor is usually sprayed from the nozzle into the combining Taper Pulleys chamber at a higher 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 good energy from the water vapor. When the combined gas stream enters the diffuser chamber, the velocity steadily decreases along the axis, and the pressure gradually boosts along the axis flow until it is discharged above the atmospheric pressure. Due to the continuous work, the gas in the gear is consistently extracted, thus causing vacuum pressure (negative pressure) state within the equipment.

3. What are the features of the steam plane vacuum pump? The steam jet vacuum pump entrains the pumped gas at a high speed of water vapor, so it has the characteristics of large pumping capability, high vacuum, simple produce, convenient set up and maintenance, etc. Currently, the vacuum distillation unit of the refinery Most of the vacuum pumps used are steam jet vacuum pumps.

4. What is the construction of the water ring vacuum pump? What is the working basic principle of the water ring 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.
