Embodiment Construction
[0019] Below in conjunction with accompanying drawing, invention will be further described.
[0020] a kind of like figure 1 In the oil pump filter screen life detection device shown, the filter screen 1 is arranged at the oil inlet of the oil pump, and it is characterized in that the detection device includes an ECU control unit, a flow meter 2 and a warning unit arranged on the oil inlet road of the oil pump, and the flow rate Meter 2 detects the oil inlet flow signal of the oil pump, and its output end is connected to the flow signal input end of the ECU control unit, and the ECU control unit is connected to the warning unit. When the flow signal collected by the flow meter 2 is greater than the flow signal of the ECU When the flow threshold set in the control unit is reached, the ECU control unit controls the warning unit to issue a warning.
[0021] Further, the ECU control unit includes a comparator and a controller, the output terminal of the flow meter is connected to...
