THE WAY THE Vacuum Pump Works

1. What is the role of the vacuum pump? What types of vacuum pumps are commonly used in refineries? The vacuum pump is designed to create vacuum pressure in the equipment or greenhouse motor container that operates below ambient atmospheric pressure or high vacuum. Vacuum pumps typically used in refineries include steam aircraft vacuum pumps, water ring vacuum pumps and reciprocating vacuum pumps.

2. What is the working basic principle of the steam plane vacuum pump? It consists of a nozzle, a combining chamber, an growth chamber, and a pressure outlet. In operation, drinking water vapor is usually sprayed from the nozzle in to the mixing chamber at a high speed (1200-1500 m/s). At this time, a specific negative pressure is produced at the nozzle, so that the pumped gas is flushed into the combining chamber from the gas inlet and mixed with water vapor. And get some good energy from the drinking water vapor. When the blended gas stream enters the diffuser chamber, the velocity gradually decreases along the axis, and the pressure gradually raises along the axis movement until it really is discharged above the atmospheric pressure. Due to the continuous function, the gas in the equipment is continually extracted, thus causing a vacuum (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 higher speed of water vapor, so it has the characteristics of large pumping capacity, high vacuum, simple manufacture, convenient installation and maintenance, etc. Presently, the vacuum distillation unit of the refinery The majority of the vacuum pumps used are steam plane vacuum pumps.

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