The inspection content of the working hydraulic system. If the operation is found to be weak, the car runs empty for a while. If the sports car feels weak, it must be the engine problem. Then check it according to the above method. If the sports car is very smooth, it can eliminate the engine problem. The next thing to do is to check the hydraulic oil pressure of the hydraulic system and see the specific data, Then judge the source of the problem according to the actual results.

怎么测压呢？搅拌机厂家先介绍一下测压口，一般常规机型，在分配阀转斗油缸的大小腔连接钢管处，都留有测压口（注意：所有的机型这里都有），在测压的时候要求连接右边的接口进行，也就是转斗油缸大腔的钢管。

How to measure the pressure? The mixer manufacturer first introduces the pressure tap. Generally, for conventional models, the pressure tap is reserved at the connecting steel pipe between the distribution valve and the large and small cavity of the rotary bucket oil cylinder (Note: all models have it here). When measuring the pressure, it is required to connect the interface on the right, that is, the steel pipe of the large cavity of the rotary bucket oil cylinder.

另外，在工作泵分配阀的进油管上面，基本所有的机型，还会多设置有一个测压口，这个测压口由于是在进油管上，所以离工作泵很近，测出来的压力也会比在转斗缸大腔钢管处测的压力高那么一点点，不过这两个检测口本质上没有区别，测哪个都可以。检测前先熄火，把铲斗翻卸料状态，让转斗油缸大腔内压力油全部泄完然后用压力表直接测测试。

In addition, on the oil inlet pipe from the working pump to the distribution valve, basically all models will be equipped with one more pressure tap. Because this pressure tap is on the oil inlet pipe, it is very close to the working pump, and the measured pressure will be a little higher than that measured at the steel pipe in the large cavity of the rotary bucket cylinder. However, the two detection ports are essentially no different, which can be measured. Turn off the engine before testing, turn the bucket to the unloading state, let all the pressure oil in the large chamber of the rotary bucket oil cylinder drain, and then use the pressure gauge to test directly.

接好压力表发动车辆，把铲斗收回来，收到头。操作手杆保持不动，同时把油门踩到底，也就是用较大的油门对收斗状态屏压，大概稳定几秒钟使压力表上的指针不再动以后，读取压力表上的数据就可以了，用这个数据和标准的数据对比（买车时的使用说明书上都有），如果低了一点，那就说明需要调整，或者系统有内漏，如果低了很多甚没有压力，那多半原因是分配阀主阀卡了，需要拆开清洗，

Connect the pressure gauge, start the vehicle, retract the bucket and receive the head. Keep the operating lever still and press the accelerator to the bottom at the same time, that is, press the bucket retraction screen with a large accelerator for about a few seconds to make the pointer on the pressure gauge stop moving, and then read the data on the pressure gauge, Compare this data with the standard data (in the user manual when buying the car). If it is a little lower, it means that adjustment is needed, or the system has internal leakage. If it is much lower or even no pressure, it is mostly because the main valve of the distribution valve is stuck and needs to be disassembled for cleaning,
