Roller vibration pump solenoid valve is new. Point road no problem. Sometimes there is no vibration. Sometimes not stop, you can always, flameout, restart no longer. Is it the pump problem? Under the guidance of an old master
The time has stopped, and there has been no vibration since it started
The senior man is right. Check the control circuit and check the vibration switch. Is the road down or loose?. If the line is normal, the pressure gauge to check the oil pressure, the various models and tonnage are different, look at instructions. To determine whether there is a problem in the oil circuit, some hydraulic oil is too dirty, deposited in the hydraulic oil filter, but also cause vibration failure...... I'm talking so much. I hope you can tell me the cause of the trouble after the repair. Thank you
Upstairs said is extremely, check control circuit. I add the following points: 1: ask: do you say the solenoid valve for the new? Why is it new? What was the trouble before?. 2: asked: "you say that the circuit is no problem, how to judge?" According to where? I put forward the inspection idea: first, judge the circuit problem: take the solenoid valve coil at both ends, turn on the power, open the Qiang Qiangzhen or weak earthquake. With a screwdriver into the coil inside the hole, if there is magnetic, that the line is through, the size of the shock, try. Instead, the coil is not called. There's something wrong with the line.
