Water pressure regulation of hot water booster pump
The water pressure regulation of the hot water booster pump is an important part to ensure that users get stable and appropriate water pressure. The following is a detailed description of the water pressure regulation of the hot water booster pump:
1. Regulation method
Throttling regulation:
By adjusting the opening of the pump outlet valve, the flow rate and lift can be controlled, and then the water pressure can be adjusted.
When the valve opening increases, the flow rate increases, and the water pressure may rise accordingly; conversely, when the valve opening decreases, the flow rate decreases, and the water pressure may decrease.
Backflow regulation:
A part of the liquid discharged by the pump is returned to the pump inlet through the reflux valve, thereby changing the actual displacement in the pump delivery pipeline to achieve the purpose of regulating water pressure.
This method is usually used in occasions where precise control of water pressure is required.
Use a pressure regulating valve:
The pressure regulating valve is a common water pressure regulating device that can control the speed and pressure of the water flow by adjusting the size of the outlet valve.
Connect the pressure regulating valve to the outlet of the hot water booster pump. By adjusting the opening of the valve, the water flow rate can be gradually increased or decreased to achieve the required water pressure.
Adjust the pressure switch:
For hot water booster pumps equipped with a pressure switch, the water pressure can be changed by adjusting the pressure adjustment knob on the pressure switch.
Counterclockwise rotation increases water pressure, and clockwise rotation reduces water pressure.
It is recommended to adjust only a small amount each time and test whether the water pressure meets the requirements.
Change the speed of the pump:
By changing the speed of the hot water booster pump, its flow, head and power can be adjusted to achieve the purpose of adjusting the water pressure.
This method usually requires the use of equipment such as frequency converters to achieve precise control of the pump speed.
2. precautions
Avoid overpressure: When adjusting the water pressure, ensure that the water pressure does not exceed the pressure bearing capacity of the hot water booster pump and the pipeline system to avoid damage to the equipment and pipelines.
Stability: The adjusted water pressure should remain stable and should not fluctuate significantly or change suddenly.
Safety: During the process of adjusting the water pressure, attention should be paid to safe operation to avoid dangerous situations such as electric shock and scalding.
Regular maintenance: To ensure the normal operation of the hot water booster pump and the stability of the water pressure, the pump and pipeline system should be maintained and inspected regularly.
In summary, water pressure regulation of hot water booster pump is a complex and important process. It is necessary to select the appropriate adjustment method according to the actual situation and pay attention to safety and stability during operation.
