Stop water intake when the water intake does not reach the set level

Analysis and maintenance: This fault is mainly due to the poor performance of the water pressure switch, so that when the air pressure in the gas collecting room has not reached the specified pressure, the contact will be converted from the disconnected state to the closed state in advance and stop the water inlet, the specific reasons and treatment methods are:

(1) The water pressure switch water level control spring precompression becomes smaller, as long as the adjusting screw increases the precompression of the water level control spring can be solved. If the water level control spring becomes less elastic or loses elasticity, the water level control spring should be replaced.

(2) The groove on the hydraulic switch CAM is worn or damaged, and the CAM can generally be solved by replacing it.
