The solution to the problem of cavitation of vacuum pump under high vacuum condition is to improve the external conditions such as the working environment of water ring vacuum, the temperature of circulating water and the temperature of suction gas as far as possible, so as to reduce the occurrence of cavitation of water ring vacuum pump.
Aiming at the manufacturing accuracy of water-ring vacuum pump, this problem is mainly the understanding and improvement of the design ability and manufacturing accuracy of water-ring vacuum pump manufacturer, which is also a test of the production capacity of water-ring vacuum pump manufacturer.
The single stage water ring vacuum pump can not meet the production requirements, but the unit cost is too high. The traditional 2SK water ring vacuum pump has many shortcomings. Aiming at various reasons, a DZKB multi-stage water ring vacuum pump is designed. Under high vacuum condition, its efficiency is 20% higher than that of single stage pump, and its performance is more stable than that of 2SK water ring vacuum pump. It is suitable for various chemical industries.
In order to improve the pumping capacity of water-ring vacuum pump in high vacuum and reduce the noise caused by air erosion, and to reduce the damage of cavitation to the internal parts of the vacuum pump, a new type of high-efficiency air ejector is specially designed. The efficiency of the new type of high-efficiency air ejector is 30% higher than that of the traditional air ejector. When used in conjunction with the water-ring vacuum pump, the pumping capacity of the water-ring vacuum pump can reach 75% of the standard air volume in the high-truth state. Above.
In the long-term cooperation with customers, vacuum pump factory also invests a lot of manpower, material resources and energy to help customers solve "difficult and complicated diseases". Especially environmental protection issues, and then the water ring vacuum pump and environmental protection equipment are closely linked. Thus a vacuum environmental protection waste liquid treatment system is designed, 100% of which adopts physical environmental protection treatment method to eliminate secondary pollution.
