The automatic booster pump is divided into several types according to different types of automatic switches. Different types of adjustment pressure methods are slightly different:
Spring pressure switch: This kind of pressure switch is the most primitive, and it mainly uses the pressure generated by the water pressure to compress the spring to turn on and off the circuit. The general lower limit pressure value of the switch can not be adjusted, and the corresponding screw on the spring switch can be adjusted to adjust the position of the upper limit switch so as to adjust the upper limit pressure value. However, the pressure value cannot be set accurately and only the blind adjustment can be performed.
Electronic voltage regulator switch: There are two types of switch, which can be started by the lower limit pressure, and the water level floating head position (depending on the flow impact force) to stop and rely on the upper and lower pressure values ​​to start and stop. Relying on the lower limit pressure value and starting the water level floating head position stop can not be adjusted; another kind of starting and stopping depending on the upper and lower limit pressure value can only adjust the upper limit stop pressure value through the end face screw, and can not accurately set the pressure value.
Differential pressure circuit switch: This is controlled by the microcomputer chip and a simple program, relative to the above two biggest progress is that you can accurately set the upper and lower limit start and stop pressure values ​​through the menu. Different switch activation settings are not the same, refer to the manual or contact us for more information.
Frequency control: This is the most advanced automatic pressure control method. Through a complex program to control the pump speed and start and stop. The common frequency conversion pump control has a separate pressure setting key. Long press the pressure setting key to activate the pressure setting. Press the up and down or left and right arrows to change the target pressure value. If some manufacturers use non-pump-specific inverters, it is necessary to adjust the pressure in the form of a percentage of the internal set range of the parameters. The specific adjustment method is related to the brand of the inverter.
