全自動混凝土攪拌車的換向閥常見故障

來源:http://www.oamenibuni.com/ 時間:2021-04-30

1.全自動混凝土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 automatic concrete mixer has been used for a long time, which is easy to cause the valve core seal ring wear, valve seat and stem damage, resulting in gas leakage in the valve, slow action or abnormal reversing of the valve. Solution: the sealing ring, valve stem and valve seat need to be replaced, or the change-over valve needs to be renewed.
2.全自動混凝土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:我們應先檢查全自動混凝土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:應更換全自動混凝土攪拌車潤滑油,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 automatic concrete mixer can not change direction or the reversing action is slow, it is generally caused by the spring stuck or damaged, poor lubrication, oil or impurities stuck in the sliding part and other reasons. Solution: we should first check whether the oil mist device of automatic concrete mixer works normally and whether the viscosity of lubricating oil is appropriate. Solution: replace the lubricating oil of the automatic concrete mixer, 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 exhaust holes of the solenoid pilot valve are blocked by oil sludge or other debris, the movable iron core is blocked, the sealing is not tight, and the circuit is faulty, the reversing valve can not be normally reversed. For the first three cases, the solutions are as follows: the oil sludge and impurities on the pilot valve and the movable iron core should be cleaned, and the circuit faults can be generally divided into circuit faults and solenoid coil faults.
在檢查全自動混凝土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 fault of the full-automatic concrete mixer, turn the manual knob of the reversing valve several times to see whether the reversing valve can change direction normally under the rated air pressure. If it can change direction normally, there is a fault in the circuit; During the inspection, the voltage of the electromagnetic coil can be measured by the instrument to see if it reaches the rated voltage. 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 can not change direction normally under the rated voltage, check whether the connector of the solenoid coil is loose or not. Check method: pull off the plug and measure the resistance of the coil. If the resistance is too large or too small, it means that the solenoid coil is damaged and needs to be replaced.
