自上料搅拌车压力不足的解决方法

查看自上料搅拌车液压泵是否能输出液压油。如果是新的液压泵,无液压油输出,可能是泵体有铸造缺陷(缩孔、砂眼等),使吸油腔和压油腔相通,失去压油能力,应及时找厂家更换。若不是新的液压泵,无液压油输出,可能是泵的转向不对,零件磨损严重或损坏,及时更换。
Check whether the hydraulic pump of the self loading mixer truck can output hydraulic oil. If it is a new hydraulic pump without hydraulic oil output, it may be that the pump body has casting defects (shrinkage cavity, sand hole, etc.), which connects the oil suction chamber and oil pressure chamber and loses the oil pressure capacity. It should be replaced by the manufacturer in time. If it is not a new hydraulic pump and there is no hydraulic oil output, it may be that the steering of the pump is wrong, and the parts are seriously worn or damaged. Replace them in time.
若自上料搅拌车液压泵有油液输出,查看溢流阀工作是否正常。若不正常,则可能是压力油路中的某个阀有污物或其他原因卡住,处于回油位置,致使压力油路与溢流回路短路。
If there is oil output from the hydraulic pump of the loading mixer truck, check whether the overflow valve works normally. If it is abnormal, it may be that a valve in the pressure oil circuit is stuck due to dirt or other reasons and is in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow circuit.
也可能是管接头松脱,或处于压力油路中的某些阀泄漏严重,或液压缸、液压马达的密封损坏,严重泄漏。排除方法是拆开有关阀进行清洗,检查密封间隙的大小及各种密封装置,密封装置损坏应更换。
It may also be that the pipe joint is loose, or some valves in the pressure oil circuit leak seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged and leak seriously. The troubleshooting method is to disassemble the relevant valves for cleaning, check the size of the sealing gap and various sealing devices, and replace the damaged sealing devices.

若自上料搅拌车的液压泵输出流量随压力升高而显着减小,且压力达不到规定值,则是由于液压泵磨损后间隙变大所致。排除方法是测定液压泵的容积效率,即可确定该泵是否能继续使用,对磨损严重的零件,应进行修配或更换。
If the output flow of the hydraulic pump from the loading mixer decreases significantly with the increase of pressure, and the pressure cannot reach the specified value, it is due to the larger clearance after the hydraulic pump is worn. The elimination method is to measure the volumetric efficiency of the hydraulic pump to determine whether the pump can continue to be used. The parts with serious wear should be repaired or replaced.
此外自上料搅拌车厂家认为搅拌车一般在施工现场,工作人员的工作质量也会影响系统的使用。在设备的维护和清洗中,传感器很可能会被高压水溅到,误操作可能导致过载。为了使传感器能够在这样的环境条件下长期可靠地工作,需要进行一些特殊的设计。
In addition, since the mixer truck manufacturer believes that the mixer truck is generally on the construction site, the work quality of the staff will also affect the use of the system. During the maintenance and cleaning of the equipment, the sensor is likely to be splashed by high-pressure water, and misoperation may lead to overload. In order to make the sensor work reliably under such environmental conditions for a long time, some special designs are needed.
