混凝土的運輸離不開(kāi)自動(dòng)上料攪拌車(chē)，所以攪拌車(chē)就顯得非常重要了，攪拌車(chē)是由多個(gè)部件組成的，所以偶爾會(huì )出現故障，比如電磁先導閥有故障等等，下面小編就給大家一一介紹一下這些故障的方法。

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.

若電磁先導閥的進(jìn)、排氣孔被油泥或其他雜物堵塞，封閉不嚴，活動(dòng)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，對于前三種情況應清洗先導閥及活動(dòng)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(xiàn)圈故障兩類(lèi)。

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.

在檢查電路故障之前，要先將換向閥的手動(dòng)旋鈕轉動(dòng)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；

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;

檢查時(shí)，可以用儀表測量電磁線(xiàn)圈的電壓，看是否達到了額定電壓，如果電壓過(guò)低，應進(jìn)一步檢查控制電路中的電源和相關(guān)聯(lián)的行程開(kāi)關(guān)電路。

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.

如果在額定電壓下?lián)Q向閥不能正常換向，則應檢查電磁圈的接頭是否松動(dòng)或接觸不實(shí)，檢查方法：拔下插頭，測量線(xiàn)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(shuō)明電磁線(xiàn)圈已損壞，需要更換。

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.

自動(dòng)上料攪拌車(chē)的電磁先導閥故障怎么處理大家都了解了嗎？希望這些知識能給駕駛攪拌車(chē)的朋友帶倆幫助。希望您在使用攪拌車(chē)進(jìn)行工作時(shí)會(huì )有一個(gè)很好的檢查保養操作，更多相關(guān)內容就來(lái)我們網(wǎng)站http://m.jackpetty.net咨詢(xún)了解吧！
