每個城市都會有一定數(shù)量的攪拌站，這是因為城市中高樓大廈的建設(shè)離不開混凝土，而混凝土的運輸離不開自動上料攪拌機，所以自動上料攪拌機就顯得非常重要了。那么自動上料攪拌機換向閥出現(xiàn)故障怎么處理呢？

Every city will have a certain number of mixing stations. This is because the construction of high-rise buildings in the city cannot be separated from concrete, and the transportation of concrete cannot be separated from the automatic feeding mixer, so the automatic feeding mixer is very important. Then how to deal with the failure of the reversing valve of the automatic feeding mixer?

1、自動上料攪拌機的換向閥不能換向或者換向動作緩慢，一般是因潤滑不良、彈簧被卡住或損壞、油污或雜質(zhì)卡住滑動部分等原因引起的。此時，我們應(yīng)先檢查油霧器的工作是否正常，潤滑油的粘度是否合適。必要時，應(yīng)更換潤滑油，清洗換向閥的滑動部分，或更換彈簧和換向閥。

1. The reversing valve of the automatic feeding mixer cannot be reversed or the reversing action is slow, which is generally caused by poor lubrication, stuck or damaged spring, oil stain or impurities stuck on the sliding part. At this time, we should first check whether the oil atomizer works normally and whether the viscosity of lubricating oil is appropriate. If necessary, replace the lubricating oil, clean the sliding part of the reversing valve, or replace the spring and the reversing valve.

2、自動上料攪拌機的換向閥經(jīng)長時間使用后容易出現(xiàn)閥芯密封圈磨損、閥桿和閥座損傷的現(xiàn)象，導(dǎo)致閥內(nèi)氣體泄漏，閥的動作緩慢或不正常換向等故障。此時，需要更換密封圈、閥桿和閥座，或?qū)Q向閥換新。

2. After long-term use, the reversing valve of the automatic feeding mixer is prone to wear of the valve core sealing ring, damage of the valve stem and valve seat, resulting in gas leakage in the valve, slow action of the valve or abnormal reversing. At this time, it is necessary to replace the sealing ring, valve rod and valve seat, or replace the reversing valve.

3、若電磁先導(dǎo)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(dǎo)致?lián)Q向閥不能正常換向，對于前三種情況應(yīng)清洗先導(dǎo)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。

3. If the inlet and outlet holes of the electromagnetic pilot valve are blocked by oil sludge or other sundries, the sealing is not tight, the movable iron core is stuck, and the circuit is faulty, etc., the reversing valve can not be normally reversed. For the first three cases, the oil sludge and impurities on the pilot valve and the movable iron core should be cleaned. Generally, the circuit fault can be divided into circuit fault and electromagnetic coil fault.

在檢查電路故障之前，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；

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

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(yīng)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。如果在額定電壓下?lián)Q向閥不能正常換向，則應(yīng)檢查電磁圈的接頭是否松動或接觸不實。

During the inspection, the voltage of the solenoid coil can be measured with an instrument to see whether the rated voltage is reached. If the voltage is too low, the power supply in the control circuit and the associated travel switch circuit should be further checked. If the reversing valve cannot normally reverse under the rated voltage, check whether the connector of the solenoid ring is loose or not.

檢查方法：拔下插頭，測量線圈的阻值（一般應(yīng)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。

Inspection 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, it indicates that the electromagnetic coil has been damaged and needs to be replaced.

自動上料攪拌機是由多個部件組成的，比如專用車底盤、上裝罐體、液壓系統(tǒng)、副車架、換向閥等等，其中換向閥也會偶爾出現(xiàn)故障，以上就是故障的處理方法內(nèi)容了，您可以作為參考使用，更多問題就來我們網(wǎng)站http://www.wishnailspa.com咨詢吧！

The automatic feeding mixer is composed of several parts, such as the chassis of the special vehicle, the loading tank body, the hydraulic system, the sub frame, the reversing valve, etc. the reversing valve also occasionally fails.
