1.自上料攪拌車的換向閥使用的時間長了容易出現閥芯密封圈磨損、閥座和閥桿損傷的情況，導致閥內氣體泄漏，閥的動作緩慢或不正常換向等故障。解決方法：需要更換密封圈、閥桿和閥座，或將換向閥換新。
1. The reversing valve of the self feeding mixer truck is prone to wear of the valve core seal ring, damage of the valve seat and valve stem after a long time of use, resulting in gas leakage in the valve, slow action of the valve or abnormal reversing and other failures. Solution: replace the sealing ring, valve rod and valve seat, or replace the reversing valve.
2.自上料攪拌車的換向閥如果出現不能換向或者換向動作緩慢的情況，一般是因彈簧被卡住或損壞、潤滑不良、油污或雜質卡住滑動部分等原因引起的。解決方法：我們應先檢查自上料攪拌車油霧器的工作是否正常，潤滑油的粘度是否合適。解決方法：應更換自上料攪拌車潤滑油，清洗換向閥的滑動部分，或更換彈簧和換向閥。
2. If the reversing valve of the self feeding mixer can not reverse or the reversing action is slow, it is generally caused by the spring being stuck or damaged, poor lubrication, oil stain or impurities blocking the sliding part, etc. Solution: We should first check whether the oil atomizer of the self feeding mixer works normally and whether the viscosity of the lubricating oil is appropriate. Solution: Replace the lubricating oil of the self feeding mixer truck, clean the sliding part of the reversing valve, or replace the spring and reversing valve.
3.若電磁先導閥的進、排氣孔被油泥或其他雜物堵塞，活動鐵芯被卡死，封閉不嚴，電路有故障等，均可導致換向閥不能正常換向，對于前三種情況解決方法：應清洗先導閥及活動鐵芯上的油泥和雜質，而電路故障一般又可分為電路故障和電磁線圈故障兩類。
3. If the inlet and outlet holes of the solenoid pilot valve are blocked by oil sludge or other debris, the movable iron core is stuck, not tightly closed, and the circuit has a fault, etc., the reversing valve can not reverse normally. For the first three cases, the solution is to clean the oil sludge and impurities on the pilot valve and the movable iron core, and the circuit fault can generally be divided into circuit fault and solenoid coil fault.
在檢查自上料攪拌車電路故障之前，要先將換向閥的手動旋鈕轉動幾下，看換向閥在額定氣壓下是否可以正常換向，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聯的行程開關電路。如果在額定電壓下換向閥不能正常換向，則應檢查電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，如果阻值太大或太小，說明電磁線圈已損壞，需要更換。
Before checking the circuit failure of the self feeding mixer truck, turn the manual knob of the reversing valve a few times to see if the reversing valve can normally reverse at the rated air pressure. If it can, the circuit is faulty; 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. 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. If the resistance is too large or too small, the solenoid coil is damaged and needs to be replaced.
