How to adjust the pressure of domestic pressure tank

Open the plastic shell of the pressure switch, which has two structural types: large and small spring columns and a large spring column. If it is necessary to increase the pressure, tighten the screw on the big spring post clockwise, and if it is necessary to reduce the pressure, loosen the screw on the big spring post.

The pressure tank uses the compressibility of air in the tank to adjust and store water and maintain the required pressure, so the installation height of the tank can be unlimited.

Pressure tanks are usually installed between the water distribution pump and the pipe network. After the water pump is started, it supplies water to the pipe network, and the excess water is stored in the water tank, so that the water level in the water tank rises, the air in the water tank is compressed, and the pressure increases accordingly. When the pressure in the tank reaches the specified upper limit pressure value, the indicator of the electric contact pressure gauge communicated with the tank top through the pipeline connects the upper limit contact, and sends a signal to cut off the power supply and stop the pump.

Precautions:

1. The pump unit of this equipment should be inspected frequently, maintained regularly and filled with lubricating oil. If the centrifugal pump and check valve are found to be leaking, the flange screws should be tightened or asbestos roots should be replaced in time, and the pump foot bolts should not be loosened to prevent damage to the machine. ?

2, electrical automatic control system, should be waterproof and dustproof, often check the line insulation, whether the connecting bolt is loose and whether the fuse is in good condition, and so on and so forth.

3. It is best to wrap the outside of the pressure gauge with transparent material to prevent damage. ?

4. If the pressure tank paint falls off, it should be painted and maintained in time to prolong its service life.
