怎样能够自上料搅拌车的气压不足问题?

概述:1 检查自上料搅拌车的液压泵是否可以输出液压油。如果是新的液压泵,则没有液压油输出,泵体可能有铸造缺陷(收缩,沙孔等)。使吸油腔和油压腔相互连通
1.检查自上料搅拌车的液压泵是否可以输出液压油。如果是新的液压泵,则没有液压油输出,泵体可能有铸造缺陷(收缩,沙孔等)。使吸油腔和油压腔相互连通,从而失去油压能力,应由制造商及时更换泵体。如果不是新的液压泵并且没有液压油输出,则可能是泵的转向错误,零件严重磨损或损坏,应及时更换。
1. Check whether the hydraulic pump of self feeding mixer can output hydraulic oil. If it is a new hydraulic pump, there is no hydraulic oil output, and the pump body may have casting defects (shrinkage, sand hole, etc.). The pump cavity and the oil pressure should be connected to each other by the manufacturer, so that the oil pressure can not be replaced in time. If it is not a new hydraulic pump and there is no hydraulic oil output, it may be the wrong steering of the pump, and the parts are seriously worn or damaged, so it should be replaced in time.
2.如果自上料搅拌车的液压泵有油输出,请检查溢流阀是否正常工作。如果不正常,则可能是压力油回路中的阀门由于灰尘或其他原因而卡住并且处于回油位置,从而导致压力油回路与溢流管线或管路之间发生短路。接头松动,或压力油回路中有一个接头。某些阀严重泄漏,或者液压缸和液压马达的密封件损坏,从而导致严重泄漏。的方法是拆卸相关的阀门进行清洗,检查密封间隙和各种密封装置的尺寸,如有损坏,请更换密封装置。
2. If the hydraulic pump of self feeding mixer has oil output, please check whether the relief valve works normally. If the pressure between the oil return circuit and the oil return circuit is not in the normal position, it may be caused by dust or other reasons. The connector is loose or there is a connector in the pressure oil circuit. Some valves have serious leakage, or the seals of hydraulic cylinder and hydraulic motor are damaged, resulting in serious leakage. The elimination method is to dismantle the relevant valve for cleaning, check the sealing clearance and the size of various sealing devices, if there is damage, please replace the sealing device.
3.如果自上料搅拌车的液压泵的输出流量随压力的增加而显着下降,而压力未达到指定值,则是由于液压泵磨损后的间隙增大所致。方法是测量液压泵的容积效率,以确定该泵是否可以继续使用。严重磨损的零件应修理或更换。
3. If the output flow of the hydraulic pump of the self feeding mixer decreases significantly with the increase of the pressure, and the pressure does not reach the specified value, it is due to the increase of the gap after the wear of the hydraulic pump. The elimination method is to measure the volumetric efficiency of the hydraulic pump to determine whether the pump can continue to be used. Severely worn parts should be repaired or replaced.
4.自上料搅拌车的液压系统可以建立常压,某些管路或液压缸(或液压马达)没有压力,这可能是由于管路,小孔或节流阀,换向阀等部件堵塞造成的。此时,应逐步检查压力和是否有油,以找出原因并。
4. The hydraulic system of self feeding mixer can establish normal pressure, and some pipelines or hydraulic cylinders (or hydraulic motors) have no pressure, which may be caused by blockage of pipelines, orifices or throttle valves, reversing valves and other parts. At this time, the pressure and oil should be checked step by step to find out the cause and eliminate it.
