混凝土的运输离不开自动上料搅拌车，所以搅拌车就显得非常重要了，搅拌车是由多个部件组成的，所以偶尔会出现故障，比如电磁先导阀有故障等等，下面小编就给大家一一介绍一下这些故障的方法。

The concrete can not be transported without the automatic feeding mixer, so the mixer truck is very important. The mixer truck is composed of multiple parts, so there are occasional failures, such as the failure of the electromagnetic pilot valve. The following brief section will introduce the solutions to these failures one by one.

若电磁先导阀的进、排气孔被油泥或其他杂物堵塞，封闭不严，活动铁芯被卡死，电路有故障等，均可导致换向阀不能正常换向，对于前三种情况应清洗先导阀及活动铁芯上的油泥和杂质，而电路故障一般又可分为电路故障和电磁线圈故障两类。

If the inlet and outlet holes of the solenoid pilot valve are blocked by oil sludge or other impurities, the sealing is not tight, the movable iron core is stuck, and the circuit has faults, etc., the directional valve can not reverse normally. For the first three cases, the oil sludge and impurities on the pilot valve and movable iron core should be cleaned, and the circuit faults can generally be divided into circuit faults and solenoid coil faults.

在检查电路故障之前，要先将换向阀的手动旋钮转动几下，看换向阀在额定的气压下是否正常换向，若能正常换向，则是电路有故障；

Before checking the circuit fault, turn the manual knob of the reversing valve a few times to see whether the reversing valve reverses normally under the rated air pressure. If it can reverse normally, the circuit is faulty;

检查时，可以用仪表测量电磁线圈的电压，看是否达到了额定电压，如果电压过低，应进一步检查控制电路中的电源和相关联的行程开关电路。

During the inspection, the instrument can be used to measure the voltage of the solenoid coil to see whether the rated voltage is reached. If the voltage is too low, further check the power supply in the control circuit and the associated travel switch circuit.

如果在额定电压下换向阀不能正常换向，则应检查电磁圈的接头是否松动或接触不实，检查方法：拔下插头，测量线圈的阻值（一般应在几百欧姆几千欧姆之间），如果阻值太大或太小，说明电磁线圈已损坏，需要更换。

If the reversing valve can not reverse normally under the rated voltage, check whether the connector of the solenoid coil is loose or not in contact. Check method: unplug the plug and measure the resistance of the coil (generally between several hundred ohms and several thousand ohms). If the resistance is too large or too small, the solenoid coil is damaged and needs to be replaced.
