S tart the motor to rotate, but the engine does not start: the stick, boom oil way logic valve is polluted, the oil filter or orifice installed in the front is blocked, so the hydraulic circuit is closed (hydraulic lock), remove the stick, boom oil way logic valve, clean the oil filter or orifice.ġ. boom rising speed is slow: the logic valve of boom oil circuit is polluted, the piston of logic valve of boom oil circuit is removed, cleaned, the logic check valve of boom oil circuit is polluted, stuck in the closed position, or the piston is stuck in the middle position, in this case, there will be noise during boom rising, the logic check valve is removed and cleaned.ģ. T he speed of the stick in and out is slow: the reason is that the logic valve of stick oil circuit is polluted, the piston orifice is blocked or the piston is stuck at the open position, so the oil output by the main pump always flows back to the hydraulic oil tank.Ģ. Fault analysis of logic valve and logic check valve:ġ. when the operating handle is in the middle position, the boom, stick and bucket move towards the side without load (such as boom, bucket opening, etc.), the secondary relief valve opens when the pressure is lower than the specified pressure, so that the secondary relief valve cannot achieve the pressure required by the cylinder load. If there is not enough pressure when a working device performs two actions (such as stick retracting and extending), check the oil filter in the hydraulic oil tank (damaged sealing debris may be found in the oil filter).Ĥ. I nsufficient power of a working device (boom rising or falling, bucket opening or closing, stick extending or retracting): the reason is that the secondary overflow valve is out of order. T he power of some working devices is insufficient (only limited to 450lc).The boom, stick, bucket, right and left traveling power are insufficient, and the main overflow valve fails.ģ. R eason for insufficient power of all working devices of r130 and r320 series: the main overflow valve has failed, so the normal working pressure cannot be established.Ģ. įault analysis of primary and secondary relief valves:ġ.
