How to adjust the pressure of the booster pump, where is the gate valve of the booster pump
Everyone for the main use of the booster pump is how much to understand some of it, for example, when the pressure of the electric water heater is insufficient in the home, it must be assembled a booster pump, so after assembly, you can meet the requirements of tap water, so how to adjust the pressure of the booster pump? Where is the gate valve for regulating the pressure of the booster pump? Today like gate valve for your detailed explanation!
First, how to adjust the pressure of the booster pump
The key to regulating pressure of pipeline booster pump is as follows:
1, throttle valve regulation: a simple way is to adjust the opening of the pump outlet valve, adjust the total flow and pump head.
2, flow back regulation: part of the liquid flow out of the pump through the oil valve back to the pump inlet, and then change the pump transport pipeline in the practice of displacement.
3, according to the change of temperature to adjust the total flow, when the ambient temperature is low, the use of oil station heating, heating station in the middle of the method.
4, active regulation: composed of intelligent transmitter active automatic control system, regulator and regulating valve by intelligent transmitter, regulator and regulating valve regulation of the material composition.
5, change the pump speed ratio adjustment: Q2/Q1= N2/N1,H2/H1=(N2/N1),N2/N1=(N2/N1) in the formula: Q1, H1, N1 centrifugal pump speed ratio is N1 of the total flow, pump head and output power. The total flow, pump head and output power of Q2, H2 and N2 centrifugal pumps when the speed ratio is N2. This set of formulas is called the fundamental Law of market share. When the speed ratio changes less than 20%, can be high efficiency will not change, with its development data error is not large.
6, change the impeller number and change the impeller diameter change method: multistage pump changes the impeller number change method. If the processing process must reduce Q and H, you can remove one or several impeller in the multistage pump.
7, laser cutting impeller aperture: reduce the impeller aperture in the pipeline booster pump, and then change the performance and characteristics of the centrifugal pump curve, adjust the total flow, pump head and motor power to transformer intention.
Two, where is the gate valve of the booster pump
1. Promote a regulating valve at the outlet of the pump, adjust the opening of the gate valve to complete the adjustment of the outlet pressure of the pump;
2, from the pump outlet lead a pipe to the pump channel, in the pipeline modification of a regulating valve, according to the adjustment of the gate valve to complete the adjustment of the pump outlet pressure;
3, frequency conversion control, according to the soft starter to adjust the pump speed ratio, complete the adjustment of the pump outlet pressure;
4, in the middle of the motor and pump refit flow liquid optical fiber coupler, according to the adjustment of the flow liquid optical fiber coupler to adjust the pump speed ratio, complete the adjustment of the pump outlet pressure
