由于就地冷再生技术具有良好的循环经济效益和效应，因此越来越受到公路养护行业的重视，那么冷再生机液压系统故障怎么进行排除？下面冷再生机租赁厂家为您解答。

As the in situ cold regeneration technology has good circular economic benefits and environmental protection effects, it has been paid more and more attention by the road maintenance industry. How to remove the fault of the hydraulic system of the cold regeneration machine? The following cold regeneration machine rental manufacturer will answer for you.

从压差阀阀芯受力分析看，该阀阀芯左侧由弹簧弹力和来自梭阀的压力油控制，右侧由流出压差阀的压力油控制。在换向阀处于中位状态下，阀芯左侧只有弹簧弹力，右侧有与系统压力相当的油压，油压作用力大于弹簧弹力，因此阀芯左移，主油道油口关闭,使压差阀出油口免于进油口压力波动冲击。

From the force analysis of the differential pressure valve core, the left side of the valve core is controlled by the spring force and the pressure oil from the shuttle valve, and the right side is controlled by the pressure oil flowing out of the differential pressure valve. When the reversing valve is in the neutral position, there is only spring force on the left side of the valve element, and there is oil pressure equivalent to the system pressure on the right side. The oil pressure force is greater than the spring force. Therefore, the valve element moves to the left, and the oil port of the main oil passage is closed, so that the oil outlet of the differential pressure valve is free from the impact of the pressure fluctuation at the oil inlet.

从压差阀功能看，当操纵换向阀时，系统压力油经过梭阀作用于压差阀阀芯左侧，使阀芯向右移动，油道口开度变大，流经压差阀的流量增大。由于换向阀对油流的节流作用，作用于压差阀阀芯两侧的油压产生压差，换向阀开度越大，压差越小。因此，换向阀开度越大，压差阀开度越大，单位时间允许流过的压力油越多，反之亦然。该阀可以起到流量补充、控制升降缸移动速度和保护系统免受冲击的作用。

From the function of the differential pressure valve, when the directional valve is operated, the system pressure oil acts on the left side of the differential pressure valve spool through the shuttle valve, making the spool move to the right, the opening of the oil passage becomes larger, and the flow through the differential pressure valve increases. Due to the throttling effect of the reversing valve on the oil flow, the oil pressure acting on both sides of the differential pressure valve spool produces a pressure difference. The greater the opening of the reversing valve, the smaller the pressure difference. Therefore, the greater the opening of the directional valve, the greater the opening of the differential pressure valve, and the more pressure oil allowed to flow through the unit time, and vice versa. The valve can supplement the flow, control the moving speed of lifting cylinder and protect the system from impact.
