Routine maintenance and spare parts recommendations for D series purge system products

Each quarter:

● Check whether the filter element and oil-water separator need to be replaced. Depending on the condition of the filter element, decide whether the next inspection time 

should be advanced to every month or postponed to half a year or one year;

Every 1 year:

● Check whether the low voltage alarm point is normal;

● Whether the pressure holding function is normal;

● Whether there is leakage in the external pipeline connection;

Every 3~5 years:

● Replace the battery;

● Whether the gland and joints are loose;

● Whether the purge time changes;

● Whether the pressure gauge functions normally;

● Check whether the sensor accuracy has changed significantly and whether it needs to be adjusted;

● Check whether the safety valve of the pressure relief unit is opened normally and whether there is a large deviation in the opening pressure;

● Whether each signal output contact can output signals normally and whether the interlocking function is normal.

Recommendations for spare parts for positive pressure cabinet purging equipment

Every half year:

● Check whether the pressure balance hole of the embedded device is blocked;

Every year:

● Check whether the low pressure sensor is functioning properly

● Check whether the flow sensor is operating normally

● Check whether the remote transmission signal is output normally

● Check whether the battery is normal

Every three years:

● Check whether the low pressure sensor value is normal

● Check whether the flow sensor value is normal

● Check whether the red and green flipping balls flip normally

● Check whether the timing module is timing normally

● Check whether the pressure holding value of the pressure relief unit is normal.

● Replace the battery
