Selection method of 2BV water ring vacuum pump

Selection method of 2BV water ring vacuum pump

At present, the manufacturers of 2BV water ring vacuum pump in the market are close to saturation and the users' usage is increasing. However, many new users don't have a special understanding of 2BV water ring vacuum pump. They often refer to the purchase situation of other customers in the same industry to choose efficient and professional 2BV water ring vacuum pump. But in fact, 2BV water ring vacuum pump mainly depends on the exhaust pressure required by the vacuum degree required by the air volume required by the customer's work, so the customer should consider the appropriateness of these aspects when purchasing.

Three selection methods of 2BV water ring vacuum pump

I. specifications with lower speed

At present, the most widely used axial suction and exhaust single acting 2BV water ring vacuum pump in the market, with multiple rotating speeds for products of the same specification. Compared with the large-scale 2BV water ring vacuum pump, the impeller is larger and the rotating speed is lower. It can be found that the rotating speed of the large-scale pump is lower, the power consumption is smaller and the operating efficiency is higher. Therefore, it is recommended that customers choose the products with lower rotating speed when purchasing 2BV water ring vacuum pump.

II. Water temperature impact should be considered

At present, the performance curve and technical parameters of 2BV water ring vacuum pump design in the market have some errors with the actual water supply temperature of most users' products in the domestic market. Therefore, when choosing the 2BV water ring vacuum pump, the customer needs to choose the product whose technical parameters are slightly higher than the actual water temperature when leaving the factory, so as to avoid the phenomenon that the water temperature is too high and cannot be used normally in actual use.

III. Effect of suction resistance

For some customers in special industries, the distance between the gas suction location of 2BV water ring vacuum pump and the vacuum pump needs to be considered. The greater the distance, the greater the loss of suction resistance will increase accordingly. Therefore, when selecting the high-performance 2BV water ring vacuum pump, it is necessary to consider the thickness and straight curve of the pipeline, try to follow the principle that the pipeline should be thick, not thin, not straight, not curved, and reduce the right angle elbow to improve the suction efficiency of 2BV water ring vacuum pump.

The above technical points are problems that customers often encounter in the actual use process. Therefore, customers should first avoid the above possible problems when purchasing 2BV water ring vacuum pump. If customers have special requirements, manufacturers can provide corresponding technical parameters according to the actual needs so as to fully meet the use needs of customers.
