The degree that the strainer blocks up may show out on the piezometer in filtering oil vehicle running process , respond to the strainer cleaning or changing a strainer in time (to have all filtering oil vehicle special use but be for replacement's using while pressure reaches 0.35 MPa,order if necessaries is other), Gage pressure continues rising when exceeding 0.4 MPa , just meeting proper motion opens a relief valve , part oil liquid essence fliteration does not pass henceforth , returns to an oil pump directly attract the oil cavity, therefore filtering oil vehicle output rate of flow just is able to come down, to play filter oil vehicle's to avoiding damaging role.

在滤油车运行过程中滤芯堵塞的程度可在压力表上显示出，当压力达到0.35MPa时，应及时清洗或更换滤芯(备有滤油车专用滤芯可供更换用，如需可另外订购)，表压继续上升超过0.4MPa时，安全阀便会自行开启，此后部分油液不经过精过滤，直接回到油泵吸油腔，所以滤油车的输出流量便会下降，以起到避免损坏滤油车的作用。
