如何提升混凝土搅拌机的液压换向阀工作效能？当然是维护保养了啊，维护保养的好，使用期就越长，工作效能就越高。

How to improve the working efficiency of the hydraulic reversing valve of the concrete mixer? Of course, it is maintenance. The better the maintenance, the longer the service life and the higher the work efficiency.

我们先讲讲搅拌机的液压换向阀，这是操纵罐机正转和翻转的机械设备，是依据齿轮油流通的方位操纵方量的开始和关闭。再说说维护保养，须要立即拆换齿轮油，立即拆换齿轮油能够降低对液压换向阀的危害，从正转改变翻转或是从翻转改变为正转的那时候，减少罐机转速比；定期维护混凝土搅拌机的液压换向阀，立即查验液压换向阀的问题，并且去处理它。

Let's first talk about the hydraulic reversing valve of the mixer, which is the mechanical equipment for controlling the forward rotation and overturning of the tank machine. It is used to control the start and closing of the volume according to the direction of the gear oil flow. Besides, for maintenance, it is necessary to immediately remove and replace the gear oil, which can reduce the harm to the hydraulic reversing valve. When the normal rotation is changed to the reverse rotation or the reverse rotation is changed to the normal rotation, the speed ratio of the tank machine can be reduced; Regularly maintain the hydraulic reversing valve of the concrete mixer, immediately check the problem of the hydraulic reversing valve and deal with it.

在液压系、阀等元件中，相对运动的元件之间都有精确的间隙，即很小的配合表面，有的液儿元件还有不少阻尼孔和缝隙式控制闯口等。如果液压油中混人污物杂质，在流经这些部位时，则会堵塞这些小孔和缝隙，使元件不能正常工作。

In the hydraulic system, valves and other components, there is a precise gap between the relatively moving components, that is, a very small mating surface. Some liquid components also have many damping holes and slot control openings. If the hydraulic oil is mixed with dirt and impurities, when flowing through these parts, these holes and gaps will be blocked and the components will not work normally.

如果污物进入阀芯与阀体等的配合间隙，则会划伤配合表面，使泄漏增加，有时甚会卡住阀芯.造成元件动作失灵。如果油液中的污物过多，则会堵塞在油泵吸袖口设置的滤油网，从而造成吸油阻力过大，使油泵小能正常1:作，产生振动和噪声。因此，应该注意以下儿点:

If dirt enters the fitting clearance between the valve core and the valve body, it will scratch the fitting surface, increase the leakage, and sometimes even jam the valve core Causing component action failure. If there is too much dirt in the oil, it will block the oil filter set at the suction sleeve of the oil pump, resulting in excessive oil suction resistance and normal operation of the oil pump, resulting in vibration and noise. Therefore, the following points should be noted:

①液压用泊须经过严格的过滤。滤油器应当经常检查清洗，如果发现损坏应及时更换。向油箱中汗油时，应通过1m目以上的滤油器过滤。

① Hydraulic berths must be strictly filtered. The oil filter shall be inspected and cleaned frequently. If it is found damaged, it shall be replaced in time. When the perspiration oil is added to the oil tank, it shall be filtered through an oil filter of 1m mesh or more.

②系统中的液压应经常检查并定期更换。一巴油液使用时间过长，将失去润滑性能，并可能具右酸性，所以一般要求在累计工作1咖h以后换油o

② The hydraulic pressure in the system shall be inspected and replaced regularly. If one bar oil is used for too long, it will lose its lubricating performance and may have right acidity. Therefore, it is generally required to change the oil after accumulating 1 hour of operation

③液压元件不要轻易拆卸。如须拆卸，则应该在重新装配时止金属屑、棉纱等杂质落人元件中。

③ Do not disassemble the hydraulic components easily. In case of disassembly, the impurities such as metal chips and cotton yarn shall be prevented from falling into the components during reassembly.
