搅拌车利用进程中,若是液压体系呈现毛病会使搅拌车的任务机能大大下降,车主伴侣们只要领会了液压体系的毛病缘由并实时排挤处置毛病才能使搅拌车规复一般,明天搜集了有关搅拌车液压体系压力缺乏或完整无压力的缘由、诊断和解除,供车主伴侣们参考进修。
In the process of using the mixer, if the hydraulic system fails, the working performance of the mixer will be greatly reduced. Only by understanding the causes of the failure of the hydraulic system and eliminating it in time, can the mixer return to normal. Today, we collected the causes, diagnosis and troubleshooting of the insufficient or no pressure of the hydraulic system of the mixer, for the reference of the owners Learning.
若是混凝土搅拌车呈现液压体系压力缺乏或完整无压力时,咱们能够按照以下几个方面顺次停止排查:
If there is insufficient or no pressure in the hydraulic system of the concrete mixer, we can check it in turn according to the following aspects:
一、查抄液压泵是不是能输入液压油。若是是新的液压泵,无液压油输入,能够是泵体有锻造缺点(缩孔、砂眼等),使吸油腔和压油腔雷同,落空压油才能,应实时找厂家改换。若不是新的液压泵,无液压油输入,则能够是泵的转向错误,整机磨损严峻或破坏,实时改换。
1、 Check whether the hydraulic pump can output hydraulic oil. If it is a new hydraulic pump and there is no hydraulic oil output, it may be that the pump body has casting defects (shrinkage cavity, sand hole, etc.), so that the oil suction cavity is connected with the oil pressure cavity and the oil pressure capacity is lost. 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 not right and the parts are seriously worn or damaged, so it should be replaced in time.

二、若液压泵有油液输入,查抄溢流阀任务是不是一般。若不一般,则能够是压力油路中的某个阀有污物或其余缘由卡住,处于回油地位,导致压力油路与溢流回路短路,也能够是管讨论松脱,或处于压力油路中的某些阀泄露严峻,或液压缸、液压马达的密封破坏,严峻泄露。
2、 If the hydraulic pump has oil output, check whether the relief valve works normally. If it is abnormal, it may be that one of the valves in the pressure oil circuit is stuck in the oil return position due to dirt or other reasons, resulting in a short circuit between the pressure oil circuit and the overflow circuit. It may also be that the pipe joint is loose, or some valves in the pressure oil circuit are seriously leaking, or the seals of the hydraulic cylinder and hydraulic Mada are damaged, resulting in serious leakage.
解除方式:拆开有关阀停止洗濯,查抄密封空隙的巨细及各类密封装配,密封装配破坏应改换。
Troubleshooting: disassemble the relevant valve for cleaning, check the size of the sealing gap and various sealing devices, and replace the damaged sealing device.
三、若液压泵输入流量随压力降低而光鲜明显减小,且压力达不到划定值,则是因为液压泵磨损后空隙增大而至。
3、 If the output flow of the hydraulic pump 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 clearance after the wear of the hydraulic pump.
解除方式:测定液压泵的容积效力,便可肯定该泵是不是能持续利用,对磨损严峻的整机,应停止修配或改换。
Elimination method: determine the volume efficiency of the hydraulic pump to determine whether the pump can continue to use, and repair or replace the worn parts.
四、若全部液压体系能成立一般压力,而某些管路或液压缸(或液压马达)中无压力,则能够是因为管路、小孔或节省阀、换向阀等部位梗塞。此时,应逐段查抄压力和有没有油液经由进程,找出缘由,加以解除。
4、 If the whole hydraulic system can establish normal pressure, but there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be due to blockage of pipelines, orifices, throttle valves, directional valves, etc. At this time, the pressure and oil flow should be checked step by step to find out the cause and eliminate it.
