What is the principle of household tap water booster pump?

The working principle of the household tap water pressure pump is similar to that of a pressure booster. It applies a very low pressure to a large-diameter air-driven piston. When this pressure acts on a small-area piston, a high pressure is generated. The booster pump can be operated continuously via a 5/2-way air-controlled directional valve. The high-pressure plunger controlled by the one-way valve continuously discharges the liquid. The outlet pressure of the booster pump is related to the air driving pressure. When the pressure between the driving part and the output liquid part reaches equilibrium, the booster pump will stop running and no longer consume air. When the output pressure drops or the air drive pressure increases, the booster pump will automatically start running until the pressure balance is reached again and automatically stop.

The household tap water pressurization pump uses a single air-controlled non-balanced gas distribution valve to realize the automatic reciprocating motion of the pump. The gas drive part of the pump body is made of aluminum alloy. The wetted part is made of carbon steel or stainless steel depending on the medium. Generally, pumps have two ports: air intake and exhaust. The air inlet that can produce a pressure lower than normal pressure (i.e. atmospheric pressure) is called "negative pressure"; the air inlet that can produce a pressure higher than normal pressure is called "positive pressure". Pressure"; for example, a vacuum pump is often referred to as a negative pressure pump, and a booster pump is a positive pressure pump. There is a big difference between a positive pressure pump and a negative pressure pump. For example, the gas flow direction, the negative pressure pump means that the external air is sucked into the exhaust nozzle; the positive pressure is sprayed out from the exhaust nozzle; such as the level of air pressure, etc.
