first, the cartridge plugging alarm 200 is removed from the hydraulic oil filter. One end of the oil extraction pipe 110 is then connected to the output port of the hydraulic pump of the backup hydraulic system. Then, the end of the first shunt 120 away from the oil extraction tube 110 is connected to one input port of the filter cartridge plugging alarm 200, and the end of the second shunt 130 away from the oil extraction tube 110 is connected to the other input port of the filter cartridge plugging alarm 200.

Finally, the differential pressure gauge 150 readings are observed and the operating condition of the cartridge plugging alarm 200 is observed. The cartridge plugging alarm 200 is externally powered.
The principle of detecting the cartridge clogging alarm 200 is as follows:
the pressure value of the hydraulic oil delivered from the first shunt tube 120 to the filter element blockage alarm 200 is set to be P 2 The pressure value of the hydraulic oil delivered from the first shunt tube 120 to the filter element blockage alarm 200 is set to be P 1 Setting P delta as the value displayed by the differential pressure table and P at the same time 1 And P 2 Is a difference in (c).
When P Δ= 0, it is checked whether the indicator lamp of the cartridge clogging alarm 200 emits light. If the indicator lights illuminate, the filter element blockage alarm 200 is abnormal. It is confirmed that the filter is not clogged, and the alarm is alarmed. If the indicator light is not illuminated, the filter cartridge plugging alarm 200 will perform well in the absence of a pressure differential condition.
When 0 < P delta < delta P, the knob on the hydraulic diverter valve 140 is adjusted so that the differential pressure value is between 0 and the original value of the cartridge plugging alarm 200. In the process of adjusting the knob, if the indicator light emits light, the filter element blockage alarm 200 is abnormal. It is confirmed that the filter is blocked but not severe, and the alarm gives an alarm. If the indicator light is not illuminated, the cartridge plugging alarm 200 will perform well in low plugging conditions.
When p= Δp, it is checked whether the indicator lamp of the cartridge clogging alarm 200 emits light. If the indicator light is not lighted, the filter element blockage alarm 200 is abnormal. It was confirmed that the filter had been severely clogged, while the alarm had not been given an alarm. If the indicator lights illuminate, the cartridge plugging alarm 200 will perform well under high plugging conditions.
