混凝土搅拌机是由多个部件组成的，比如专用车底盘、上装罐体、换向阀等等，其中换向阀会偶尔出现故障，而混凝土搅拌机电路有故障会导致换向阀异常！下面来讲讲什么情况吧。

　　Since the feeding mixer is composed of a number of components, such as special car chassis, tank, reversing valve and so on, the reversing valve will occasionally fail, and since the feeding mixer circuit failure will lead to abnormal reversing valve! So let's talk about what's going on.

　　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，对于有些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 electromagnetic pilot valve inlet and vent by sludge or other sundry jam, closed lax, activity core was jammed, a fault circuit, etc., all can lead to directional valve can't normal commutation, for some cases should be cleaning pilot valve and activity sludge and impurities on the iron core, and circuit fault in general can be divided into two categories, the failure of circuit and electromagnetic coil.

　　在检查混凝土搅拌机电路故障之前，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；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。

　　Before checking the circuit fault of the feeding mixer, the manual knob of the reversing valve should be turned several times to see whether the reversing valve is normal under the rated air pressure. If it can be normal, the circuit is faulty; When checking, you can use a meter to measure the voltage of the electromagnetic coil to see if it reaches the rated voltage. If the voltage is too low, you should 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，则应检查混凝土搅拌机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 cannot normal reversing reversing valve, under rated voltage should check the loading truck mixer magnetic ring joint is loose or contact false, inspection method: remove the plug, measuring coil resistance （generally should be in the hundreds of ohm to thousands of ohms）， if the value is too big or too small, explain the electromagnetic coil is damaged, need to change.

　　混凝土搅拌机电路有故障会导致换向阀异常的相关内容便是这样了，所以说平常使用的时候不仅要做好相关的检查工作也要定期对其进行维护。更多了解就来网站www.zkhntjbj.com看看资讯吧！

　　Since the feeding mixer circuit failure will lead to abnormal reversing valve related content is such, so it is not only necessary to do a good job of related inspection work but also to regularly maintain it. For more information, please visit www.zkhntjbj.com.
