混凝土攪拌機是由多個部件組成的，比如專用車底盤、上裝罐體、換向閥等等，其中換向閥會偶爾出現(xiàn)故障，而混凝土攪拌機電路有故障會導致?lián)Q向閥異常！下面來講講什么情況吧。

　　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.

　　若電磁先導閥的進、排氣孔被油泥或其他雜物堵塞，封閉不嚴，活動鐵芯被卡死，電路有故障等，均可導致?lián)Q向閥不能正常換向，對于有些情況應清洗先導閥及活動鐵芯上的油泥和雜質(zhì)，而電路故障一般又可分為電路故障和電磁線圈故障兩類。

　　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.

　　在檢查混凝土攪拌機電路故障之前，要先將換向閥的手動旋鈕轉(zhuǎn)動幾下，看換向閥在額定的氣壓下是否正常換向，若能正常換向，則是電路有故障；檢查時，可以用儀表測量電磁線圈的電壓，看是否達到了額定電壓，如果電壓過低，應進一步檢查控制電路中的電源和相關(guān)聯(lián)的行程開關(guān)電路。

　　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.

　　如果在額定電壓下?lián)Q向閥不能正常換向，則應檢查混凝土攪拌機磁圈的接頭是否松動或接觸不實，檢查方法：拔下插頭，測量線圈的阻值（一般應在幾百歐姆幾千歐姆之間），如果阻值太大或太小，說明電磁線圈已損壞，需要更換。

　　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.

　　混凝土攪拌機電路有故障會導致?lián)Q向閥異常的相關(guān)內(nèi)容便是這樣了，所以說平常使用的時候不僅要做好相關(guān)的檢查工作也要定期對其進行維護。更多了解就來網(wǎng)站www.wishnailspa.com看看資訊吧！

　　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.wishnailspa.com.
