全自动搅拌车建筑工程中使用多的一种专用车，主要组成部分是底盘和上装罐体，在车辆行驶的过程中，罐体是匀速转动的，而罐体的转动是依靠液压系统来实现的，液压系统中的重要组成部分就是液压马达，因为它的使用频率高，使用环境较差，所以偶尔也会出现一些故障，那液压马达常见的故障有哪些呢？
A kind of special vehicle widely used in the construction of fully automatic mixer truck. Its main components are the chassis and upper tank. During the driving process of the vehicle, the tank rotates at a constant speed, and the rotation of the tank is realized by the hydraulic system. The hydraulic motor is an important component of the hydraulic system. Because of its high frequency of use and poor use environment, some failures occasionally occur, What are the common faults of hydraulic motor?
故障一：供油量不足导致输出转速和输出转矩低
Fault 1: Low output speed and torque due to insufficient fuel supply
分析原因及办法：供油液压泵吸油口过滤器堵塞，此时可清洗滤油器；油液钻度过大，此时可更换适合的油液；轴向或径向间隙过大等原因等造成，此时要研磨定子或其他有关零件，使轴向间隙符合要求。
Analysis of causes and solutions: the filter at the oil suction port of the oil supply hydraulic pump is blocked, and the oil filter can be cleaned at this time; If the oil drill is too large, the proper oil can be replaced; If the axial or radial clearance is too large, grind the stator or other relevant parts to make the axial clearance meet the requirements.
故障二：液压马达的原动机功率或转速不当导致输出转速和输出转矩低
Fault 2: Improper power or speed of prime mover of hydraulic motor leads to low output speed and torque
分析原因及办法：原动机功率不匹配，此时需要更换原动机，使之与液压泵功率匹配；原动机转速低于额定转速，此时可选用转速满足要求的原动机。
Analysis of causes and solutions: the power of the prime mover does not match. At this time, the prime mover needs to be replaced to match the power of the hydraulic pump; If the speed of prime mover is lower than the rated speed, prime mover meeting the requirements can be selected.
故障三：各连接处密封不严，有空气混入
Fault 3: All connections are not tightly sealed and air is mixed
办法：检查和紧固各连接处，提高密封性能。
Solution: Check and tighten the joints to improve the sealing performance.
故障四：工作介质污染，液压马达内部通道被堵塞
Fault 4: The working medium is polluted and the internal channel of the hydraulic motor is blocked
解办法：拆解，仔细清洗并更换清洁的工作介质。
Solution: Disassemble, carefully clean and replace the clean working medium.
故障五：配流盘和叶片磨损，内泄漏大
Fault 5: The valve plate and blade are worn and the internal leakage is large
办法：修复或更换有关零件。
Solution: repair or replace relevant parts.
故障六：液压系统中单向阀密封不良
Fault 6: The one-way valve in the hydraulic system is poorly sealed
办法：修理单向阀阀座或更换有关零件，使阀座与钢球严格密合。
Solution: Repair the check valve seat or replace the relevant parts to make the valve seat closely fit with the steel ball.
故障七：液压系统中溢流阀失灵
Fault 7: overflow valve in hydraulic system fails
办法：修理或更换溢流阀。
Solution: repair or replace the relief valve.
以上就是全自动搅拌车液压马达比较常见的故障及原因办法，但这些也仅仅是一部分故障，大家在用车的过程中须得掌握一些修车技能，这样才不于在关键时刻“掉链子”。关注我们http://www.zkzdsljbc.com，了解更多的事项！
The above are the common failures and causes of the hydraulic motor of the fully automatic mixer, but these are only part of the failures. You must master some repair skills in the process of using the vehicle, so that you will not "lose the chain" at the critical moment. Follow us http://www.zkzdsljbc.com , learn more!
