1. What is the role of the vacuum pump? What kinds of vacuum pumps are commonly found in refineries? The vacuum pump is designed to create a vacuum in the equipment or container that functions 
2. What’s the working basic principle of the steam plane vacuum pump? It contains a nozzle, a blending chamber, an growth chamber, and a pressure store. In operation, drinking water vapor is usually sprayed from the nozzle in to the combining 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 combining chamber from the gas inlet and mixed with drinking water vapor. And get some good energy from the water vapor. When the blended gas stream enters the diffuser chamber, the velocity steadily decreases along the axis, and the pressure gradually increases along the axis movement until it really is discharged above the atmospheric pressure. Because of the continuous work, the gas in the gear is constantly extracted, thus causing a vacuum (negative pressure) state in 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 drinking water vapor, so it has the characteristics of huge pumping capability, high vacuum, simple produce, convenient installation and maintenance, etc. Currently, the vacuum distillation device of the refinery The majority of the vacuum pumps used are steam jet vacuum pumps.
4. What is the construction of the water ring 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 ring, a suction chamber, a discharge chamber, and a vent hole.
