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.

怎么測壓呢？攪拌機廠家先介紹一下測壓口，一般常規機型，在分配閥至轉斗油缸的大小腔連接鋼管處，都留有測壓口（注意：所有的機型這里都有），在測壓的時候要求連接右邊的接口進行，也就是轉斗油缸大腔的鋼管。

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，在工作泵至分配閥的進油管上面，基本所有的機型，還會多設置有一個測壓口，這個測壓口由于是在進油管上，所以離工作泵很近，測出來的壓力也會比在轉斗缸大腔鋼管處測的壓力高那么一點點，不過這兩個檢測口本質上沒有區別，測哪個都可以。檢測前先熄火，把鏟斗翻至卸料狀態，讓轉斗油缸大腔內壓力油全部泄完然后用壓力表直接測測試。

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.

接好壓力表發動車輛，把鏟斗收回來，收到頭。操作手桿保持不動，同時把油門踩到底，也就是用較大的油門對收斗狀態屏壓，大概穩定幾秒鐘使壓力表上的指針不再動以后，讀取壓力表上的數據就可以了，用這個數據和標準的數據對比（買車時的使用說明書上都有），如果低了一點，那就說明需要調整，或者系統有內漏，如果低了很多甚至沒有壓力，那多半原因是分配閥主閥卡了，需要拆開清洗，

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,
