挖掘机液压油泵磨损原因及改进方法效果

日期:2022-06-13   来源:http://www.dybocheng.com
当挖掘机液压油泵对挖掘机的严重磨损有致命的影响,所以挖掘机这样的问题必须及时解决。下面来讲讲挖掘机液压油泵磨损原因及改进方法效果的相关内容吧。
When the hydraulic oil pump of excavator has a fatal impact on the serious wear of excavator, the problem of excavator must be solved in time. Let's talk about the reasons for the wear of the hydraulic oil pump of the excavator and the related contents of the improvement methods.
挖掘机液压油泵磨损原因
Wear causes of hydraulic oil pump of excavator
(1)检查动臂油缸的内部泄漏
(1) Check the internal leakage of the boom cylinder
更简单的挖掘机液压油泵维修方法是动臂升起,看是否有明显的自由下降。 如果检查了气瓶的拆卸,如果已经磨损,应更换密封件。
The simplest maintenance method for excavator hydraulic oil pump is to raise the boom to see if there is obvious free fall. If the disassembly of the cylinder is checked, replace the seal if it is worn.
(2)检查控制阀
(2) Check the control valve
清洁长臂挖掘机的安全阀,检查阀芯磨损,如磨损应更换。 安全阀安装后仍然没有变化,然后检查操作阀芯的磨损情况,间隙一般限于0.06MM,磨损应予以更换。
Clean the safety valve of the long arm excavator, check the wear of the valve element, and replace it if worn. The safety valve is still unchanged after installation, and then check the wear of the operating valve element. The clearance is generally limited to 0.06mm, and the worn valve element should be replaced.
(3) 测量液压油泵的压力
(3) Measure the pressure of the hydraulic oil pump
若压力偏低,则进行调整,加压力仍调不上去,则说明液压油泵严重磨损。
If the pressure is low, adjust it. If the pressure cannot be adjusted, it indicates that the hydraulic oil pump is seriously worn.

改进及效果
Improvement and effect
经过几次示范,挖掘机上的液压油泵维修更终采用先进优先阀和负载传感全液压转向模式,新系统可以按照转向要求,优先分配流量,无论尺寸如何 负载,方向盘速度为保证充足的油量,剩余部分可用于提供回路的所有工作,从而消除由于功率损耗引起的过度转向回路的功率,提高系统效率和 减少液压油泵的工作压力。 减少挖掘机液压油泵严重磨损。
After several demonstrations, the hydraulic oil pump maintenance on the excavator finally adopts the advanced priority valve and load sensing full hydraulic steering mode. The new system can give priority to the distribution of flow according to the Steering requirements. Regardless of the size of the load, the steering wheel speed can be used to provide all the work of the circuit, so as to eliminate the power of the excessive steering circuit caused by power loss, Improve the system efficiency and reduce the working pressure of the hydraulic oil pump. Reduce severe wear of hydraulic oil pump of excavator.
降低系统工作压力。 通过优化计算,动臂缸使用标准系列80/4。 丹尼森液压泵的排量从10ML / R增加到14ML / R,系统设定压力为14MPA,以满足起重缸气缸升力和速度要求。
Reduce the working pressure of the system. Through optimization calculation, the boom cylinder uses the standard series 80/4. The displacement of Denison hydraulic pump is increased from 10ml / R to 14ml / R, and the set pressure of the system is 14MPa to meet the lifting force and speed requirements of the lifting cylinder.
在使用长臂挖掘机的过程中还要注意正确使用和维护,定期添加或更换液压油,以保持液压油的清洁度,以加强日常检查和维护。 为了避免挖掘机丹尼森液压泵严重磨损,以减少挖掘机液压油泵维修次数。
In the process of using the long arm excavator, pay attention to the correct use and maintenance. Add or replace the hydraulic oil regularly to maintain the cleanliness of the hydraulic oil and strengthen the daily inspection and maintenance. In order to avoid serious wear of Dennison hydraulic pump of excavator and reduce the maintenance times of hydraulic oil pump of excavator.
