全自动混凝土搅拌车的换向阀常见故障

来源:http://www.zkzdsljbc.com/ 时间:2021-04-30

1.全自动混凝土搅拌车的换向阀使用的时间长了容易出现阀芯密封圈磨损、阀座和阀杆损伤的情况,导致阀内气体泄漏,阀的动作缓慢或不正常换向等故障。方法:需要更换密封圈、阀杆和阀座,或将换向阀换新。
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.全自动混凝土搅拌车的换向阀如果出现不能换向或者换向动作缓慢的情况,一般是因弹簧被卡住或损坏、润滑不良、油污或杂质卡住滑动部分等原因引起的。方法:我们应先检查全自动混凝土搅拌车油雾器的工作是否正常,润滑油的粘度是否合适。方法:应更换全自动混凝土搅拌车润滑油,清洗换向阀的滑动部分,或更换弹簧和换向阀。

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.若电磁先导阀的进、排气孔被油泥或其他杂物堵塞,活动铁芯被卡死,封闭不严,电路有故障等,均可导致换向阀不能正常换向,对于前三种情况方法:应清洗先导阀及活动铁芯上的油泥和杂质,而电路故障一般又可分为电路故障和电磁线圈故障两类。
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.
在检查全自动混凝土搅拌车电路故障之前,要先将换向阀的手动旋钮转动几下,看换向阀在额定气压下是否可以正常换向,若能正常换向,则是电路有故障;检查时,可以用仪表测量电磁线圈的电压,看是否达到了额定电压,如果电压过低,应进一步检查控制电路中的电源和相关联的行程开关电路。如果在额定电压下换向阀不能正常换向,则应检查电磁圈的接头是否松动或接触不实,检查方法:拔下插头,测量线圈的阻值,如果阻值太大或太小,说明电磁线圈已损坏,需要更换。
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.
