Commitment to Excellence in Production
It is used to monitor the pressure in piping or equipment and automatically control the start and stop of equipment (e.g., pumps, solenoid valves, compressors, etc.) through preset high-pressure (HP) and low-pressure (LP) thresholds, to realize pressure protection or automatic make-up/exhaust functions.
Tip: Use a pressure gauge to monitor the adjustment in real time, and lock it after adjustment to prevent it from loosening.
High pressure protection: When the pressure switch detects that the system pressure is too high, it cuts off the power to the solenoid valve and closes the fluid path.
Low pressure protection: when pressure is too low, disconnect the solenoid valve circuit to prevent idling or leakage.
Safety protection: to avoid overpressure damage to equipment (e.g. compressor, piping) or low pressure leading to loss of efficiency (e.g. insufficient refrigerant).
Automation control: Automatically start and stop the solenoid valve according to the pressure signal without manual intervention.
Pressure range: The set value of the pressure switch should cover the working pressure of the solenoid valve (e.g. high pressure switch ≤ solenoid valve pressure limit).
Electrical compatibility: Both voltages/currents should be the same (e.g. 24V DC or 220V AC).
Possible cause:
Pressure switch setting is wrong (higher than actual pressure).
Pressure connection clogged or diaphragm damaged.
Circuit wiring faulty (e.g. contacts oxidized).
Need to check:
Is the solenoid coil burned out.
Are the pressure switch contacts conducting/disconnecting properly.
Is the control wiring disconnected.
Adjust the pressure switch: increase the differential pressure (difference between Cut-out and Cut-in).
Add cushioning devices: e.g. accumulators or damping holes.
Check the solenoid valve response speed: too fast switching may cause pressure fluctuations.
Avoid vibration or shock.The high voltage switch is mounted on the high voltage side of the system and the low voltage switch is mounted on the low voltage side.
