The mixer truck is generally used to transport concrete to the construction site. The housing industry is very hot, so the construction site is very busy. The Zhongke Jufeng mixer truck is also nonstop. The hydraulic system of the mixer truck is frequently used. Many drivers report that the temperature of the hydraulic system of the mixer truck is too high. Then how can I deal with these problems? First of all, we need to know what the reason is, so that we can Can solve the problem fundamentally.

　　廠家的技術(shù)人員告訴我們，造成液壓系統(tǒng)高溫的原因有5個:

　　The technicians of Zhongke Jufeng factory told us that there are five reasons for the high temperature of the hydraulic system:

　　1.嚴(yán)重泄漏的液壓系統(tǒng),如果溢流閥設(shè)定壓力過高,過多的運(yùn)動部件的磨損會使密封間隙增加,密封裝置損壞,油粘度太低,會導(dǎo)致泄漏增加,找到解決問題的原因。

　　1. For the hydraulic system with serious leakage, if the set pressure of the relief valve is too high, the wear of too many moving parts will increase the sealing clearance, damage the sealing device, and low oil viscosity, which will lead to the increase of leakage. Find out the reason to solve the problem.

　　2.液壓系統(tǒng)散熱不良。如油箱散熱面積不足，油箱油位過低。

　　2. Poor heat dissipation of hydraulic system. If the heat dissipation area of the oil tank is insufficient, the oil level of the oil tank is too low.

　　3.油的粘度太大，也會造成水力損失太大。

　　3. The viscosity of oil is too large, which will cause too much hydraulic loss.

　　4.卸荷回路的液壓系統(tǒng),當(dāng)水泥自動攪拌車系統(tǒng)卸載循環(huán)工作不良或沒有卸貨,混合器系統(tǒng)不需要強(qiáng)調(diào),和石油仍在安全閥設(shè)置溢流罐的工作壓力下,或在卸貨壓力高的意思是回油,這個時候應(yīng)該仔細(xì)檢查正常卸載電路工作系統(tǒng),如果卸油方式被污垢,或電氣系統(tǒng)故障,由于電磁閥卸荷效果不能工作，應(yīng)及時采取措施加以排除。

　　4. For the hydraulic system of the unloading circuit, when the unloading cycle of the concrete mixer system is poor or there is no unloading, the mixer system does not need to emphasize, and the oil is still under the working pressure of the overflow tank set by the safety valve, or the unloading pressure is high, which means oil return. At this time, the normal unloading circuit working system should be carefully checked, if the unloading mode is dirty, or the electrical system fails, As the unloading effect of the solenoid valve cannot work, measures should be taken to eliminate it in time.

　　5.如果上述故障排除后,液壓系統(tǒng)仍然存在高溫的問題,有可能是由于直接影響油溫升高速度控制方法,系統(tǒng)壓力、液壓缸、泵和電機(jī)的效率,額定流量的直徑的各種閥門、管道、油箱體積,在液壓和卸貨的問題處理不當(dāng)造成的,應(yīng)該結(jié)合實際,具體分析,得出正確的結(jié)論。

　　5. If the problem of high temperature still exists in the hydraulic system after the above troubleshooting, it may be caused by the improper handling of various valves, pipes and tank volumes that directly affect the speed control method of oil temperature rise, the system pressure, the efficiency of hydraulic cylinders, pumps and motors, the diameter of rated flow, and the problems of hydraulic pressure and unloading, it should be combined with the actual situation and analyzed in detail to draw correct conclusions.

　　總之，無論發(fā)生什么樣的混車故障，一定要冷靜，首先找到故障的根源，這樣才能迅速解決問題!

　　In a word, no matter what kind of mixed vehicle fault happens, we must be calm and find the root cause of the fault first, so as to solve the problem quickly!
