(Summary description)The essence of changing the valve switch on the outlet pipeline of the customized Centrifugal Pump price is to change the pipeline characteristic curve. When the valve is closed small, the local resistance of the pipeline increases, the pipeline characteristic curve becomes steep, the operating point moves from M to M1, and the flow rate decreases from QM to QM1.

How much do you know about the flow regulation knowledge of customized Centrifugal Pump price? Let's take a look at it briefly!
1. Change the opening of the valve
The essence of changing the valve switch on the outlet pipeline of the customized Centrifugal Pump price is to change the pipeline characteristic curve. When the valve is closed small, the local resistance of the pipeline increases, the pipeline characteristic curve becomes steep, the operating point moves from M to M1, and the flow rate decreases from QM to QM1. When the valve is opened larger, the pipeline resistance decreases, the pipeline characteristic curve becomes flatter, the operating point moves to M2, and the flow rate increases to QM2.
It is quick and convenient to use the valve to adjust the flow rate, and the flow rate can be continuously changed, which is suitable for the characteristics of continuous chemical production. So the application is very wide. The disadvantage is that the valve is closed for hours, the resistance loss increases, and the energy consumption increases, which is very uneconomical.
2. Change the speed of the pump
Changing the speed of the pump is essentially changing the characteristic curve of the pump. The original speed of the pump is n and the working point is M. If the speed of the pump is increased to n1, the characteristic curve of the pump H——Q will move up, the working point will be moved from M to M1, and the flow will be increased from QM to QM1. If the pump speed is reduced to n2, the operating point is moved to M2, and the flow rate is reduced to QM2.
The above is about the flow regulation knowledge of customized Centrifugal Pump price.
