Through the analysis of the global vacuum pump market, we can see that the market and application fields of various vacuum pumps are constantly changing and developing. China's vacuum pump manufacturing industry has a long history and a solid foundation. Domestic vacuum pumps have been applied and verified in various fields. Some pumps are also exported to foreign countries, recognized and praised by foreign users. It should be said that China's vacuum pump manufacturing industry still has a huge development space in the domestic and foreign markets.
Although the water ring vacuum pump belongs to the crude vacuum pump, it still has a large market in the fields of petroleum, chemical industry, electric power, light textile, paper making, medicine and so on. In foreign countries, the sales volume of water ring pump accounts for 14% of the total vacuum pump market, second only to dry pump. Because most of water ring pumps are castings with low processing requirements, they are labor-intensive products, so domestic water ring pumps have a competitive advantage in price. The key is to improve design, reduce volume, reduce weight, improve efficiency and reduce energy consumption.
