flows into the pump body assembly 1, one inlet end of the communicating pipe 402 is communicated with other conveying equipment, when the hydraulic oil passes through the flowmeter body 401, the flowmeter body 401 monitors the flow value, when the flow rate is obviously reduced, the flow property of the hydraulic oil is poor when the hydraulic oil passes through the filter assembly 3, at the moment, the pressure difference between the inlet and the outlet of the filter assembly 3 can be monitored through the differential pressure sensor 5, when the pressure difference exceeds a normal range, the inside of the filter assembly 3 is indicated to be blocked, so that the pressure difference between the liquid inlet end 302 and the liquid outlet end 303 is overlarge, then, when in normal use, the hydraulic oil passes through the communicating pipe 402 and the liquid inlet end 302, the hydraulic oil mixed with impurities enters the filter pipe 304, the impurities are filtered and blocked by the filter core plate 305 and the filter holes 306, the filtered clean hydraulic oil flows to the liquid outlet end 303 through the filter core plate 305 and the filter holes 306, impurities slide and accumulate at the tail end of the discharging pipe 307 through the filter pipe 304 under the action of gravity, after long-time use, the accumulated impurities are more and more, the differential pressure sensor 5 and the flowmeter main body 401 respectively monitor that the differential pressure is overlarge and the flow value is reduced, and an abnormal signal is transmitted

mounted, each sealing block 119 is clamped in corresponding to the position of the positioning block 118, the rotating block 121 rotates in the rotating groove 120, when the driving rotating shaft 113 rotates, the two movable shafts 122 and the pressure oil gears 123 on the surfaces of the movable shafts are driven to be meshed and rotated, when the pressure oil gears 123 start to rotate, the two pressure oil gears 123 are meshed with each other, in the rotating process of the pressure oil gears 123, the gap of the pressure oil gears 123 is gradually communicated with the volume of the inner cavity of the protective housing 102, a negative pressure area is formed, under the action of negative pressure, liquid enters the inner cavity of the protective housing 102 from the liquid inlet 105, when the pressure oil gears 123 continue to rotate, the negative pressure area is gradually communicated with the liquid outlet 103, at the moment, the liquid is pushed out of the inner cavity of the
