1: The working principle of water-flow automatic booster pump: Push the water-flow sensor (water-flow switch) in the pump through the flow of water pipe (4L per minute). The sensor transmits the signal to the controller in the pump. The controller controls the pump motor and the pump works to supply water under pressure.
Advantages: compact structure, simple principle and low price
Defect: Water flow switch is easily blocked.
2: Pressure type automatic booster pump
Working Principle: The pump is controlled by the pressure sensor (upper and lower limit) in the induction pipe of the pump. When the pressure in the pipe reaches the upper limit of the pump pressure sensor, the pump stops working and starts when the pressure sensor is lower than the lower limit of the pump pressure sensor.
Advantages: Open water can be extracted at a low price.
Defects: The contacts in the pressure sensor are easy to sinter (the pump can not work). If the impeller is not used for a long time, it will be easy to jam with the pump body (water rust) and the motor will burn out after the jam. When the water flow is small, the pump pressure sensor will not stop running between the upper limit and the lower limit.
3：电子稳压式自动增压泵工作原理：经过水流感应器(高灵活度)和压力感应器(电子式，没有工作电流)感应水管 压力和水流来控制水泵开停。当水管内压力降落，水泵压力感应器给水泵控制器一个信号，水泵启开工作，同时水流 感应器也感应到有水流活动，水泵工作，当用水量渐渐减少，压力到达上限压力感应器给控制器提供停机信号，但是水流感应器还是提供的工作信号(只是流量减 小)水泵控制器还是控制水泵工作，直到水流感应器感应不到水流和压力感应器到达上限水泵才中止工作。
3: The working principle of the electronic pressurized automatic booster pump: through the flow inductor (high flexibility) and pressure inductor (electronic, no working current) induction pipe pressure and water flow to control the start and stop of the pump. When the pressure in the pipe falls, the pump pressure sensor gives a signal to the pump controller. The pump starts to work. At the same time, the water flow sensor also senses the flow activity. The pump works. When the water consumption decreases gradually, the pressure reaches the upper limit and the pressure sensor provides the stop signal to the controller. However, the water flow sensor still provides the working signal (only the flow rate decreases) to the pump controller. It is to control the operation of the pump until the flow sensor can not sense the flow and pressure sensor reaches the upper limit of the pump.
Advantages: stable outlet pressure, compact structure, long service life, with water shortage maintenance defects: slightly higher price
4: Frequency conversion constant pressure water supply pump (system) working principle: through the pressure sensor induction pipe pressure, output electronic signal to the frequency converter to control the speed of the pump motor, play a constant pressure role.
Advantages: saving electricity, adjustable working pressure, long service life, light voice defects: high price is what Xiaobian said about hot water booster pump knowledge, I hope you can better understand hot water booster pump after reading. Hot water booster pump is a very good delivery equipment, especially in domestic water, industrial water, cooling system water and regional heating system is very important. In addition, hot water booster pump is also very commonly used in chemical industry, textile, wood processing and metallurgy. Because of its excellent stability, easy maintenance and noise. The sound is also very small.
