How to adjust the pressure of booster pump?

Just adjust the air pressure switch. Open the box of air pressure switch with a screwdriver, usually marked with+,-or size, and adjust according to this.

Air pump, that is, "air pump", is a device that draws air from a closed space or supplements air from a closed space. Air pumps are mainly divided into electric air pumps, manual air pumps and pedal air pumps. Electric air pump, an air pump powered by electricity, continuously compresses air through electricity to generate air pressure.

Electric air pump, mainly used for air extraction, sewage treatment, electroplating blowing, biogas digester aeration, tunnel ventilation and so on. On the switch box of 0 1 air pump, there is an air inlet switch (red) with a small hole beside it, which can be opened with a screwdriver. The pressure adjusting spring of the air pump (you can see the external hexagon nut above) is used to adjust the pressure. Turn on the air pump and open the air valve.

Adjust the nut counterclockwise and observe the numerical change of the pressure gauge. When the pointer reaches 4-5 kg. Select the pressure. Reassemble the air inlet switch box of air pump. The working pressure for cleaning domestic water pipes is 4-5 kg. Clean the heating pipe with 7-8KG pressure. The pressure cannot be adjusted to more than 8 kg.
