Excavator mechanical accessories for SK200-6E short-line hydraulic pump proportional solenoid valve YN35V00004F1

Proportional electromagnet failure causes ① Due to the plug assembly wiring socket (base) aging, poor contact and electromagnet lead welding and other reasons, resulting in the proportional electromagnet can not work properly (can not pass the current). At this time, you can use the meter to detect, if the resistance is found to be infinite, you can re-solder the lead, repair the socket, and ensure that the socket is stable. The possible failures of wire assembly include coil aging, wire burnout, internal coil disconnection and excessive temperature rise. Too high temperature rise will lead to insufficient output force of the proportional electromagnet, and other failures will also make it lose function. For the problem of excessive temperature rise, you can check whether the current exceeds the standard, whether there is poor enamel insulation and the valve core is blocked by dirt, and find out the reasons and eliminate them; In the case of disconnection or damage, the entire wire assembly needs to be replaced.
