2BV Water Ring Vacuum Pump Model

Before using, we should first determine the type of 2BV water ring vacuum pump to determine whether it is the product we need. Different models of the corresponding use of equipment will also have a certain difference, choose the right model can help use. If the model is incorrect, it will not work properly.

1. According to the technological parameters of the device, the physical and chemical properties of the conveying medium and the structural characteristics of our products and the suitable working position, we can decide which series of pumps to choose.

2. Then determine the rated flow rate of 2BV water ring vacuum pump.

3. Determine its rated lift.

4. Then the rated motor of 2BV water ring vacuum pump is determined.

5. Looking at the type spectrum of the selected series of pumps, which type of frame should the flow rate and head fall into, we can preliminarily determine the selected type. Usually, under different rotational speeds, one type may be selected.

6. Check the performance curve of the preliminary selected model and check whether the NPSHr of the pump meets the requirement of NPSHa of the device.

7. Check the performance curve to verify whether the rated working point of the selected model falls in the effective working area of the pump. Comparing the efficiency, speed (lower speed, longer service life) and price of the pump comprehensively, the model of 2BV water ring vacuum pump is determined.
