挖掘机摆脱“痴呆症”
Excavators Overcoming "Dementia"
你是不是经常遇到
挖机无力无论是回转还是动作
都像得了老年痴呆症一般
今天就教大家几招
轻松解决挖机动作缓慢问题
Have you often encountered situations where the excavator seems to suffer from old-age dementia, moving slowly and awkwardly regardless of rotation or movement?Today, let us share a few easy ways to solve the problem of slow excavator movements.
部件动作缓慢
Slow Action of Components
单一的动作实施时操作缓慢，包括行走、抬臂、转身、挖斗转动等操作，这种情况一般可以从三个方面寻找故障原因。
When implementing a single action, such as walking, lifting the arm, turning, rotating the bucket, etc., the operation is slow. This situation can generally be analyzed from three aspects.
部件自身故障
Component Malfunctions
即动作部件自身接受信息不良或者实施过程中接触不良，或者相关组件自身溢流阀压力过低，挖掘机手可通过敲打部件看是否有螺丝松动或者压力测试，从而进行维修处理。
This refers to the poor reception of information by the action components themselves or poor contact during implementation. It can also be due to low pressure in the overflow valve of the relevant component. Operators can check by tapping the components to see if any screws are loose or conduct pressure tests to identify issues and proceed with repairs accordingly.
传导过程故障
Transmission Process Malfunction
即命令传导过程中发生故障，阻碍命令信号的传递，因此可以重点检查泵、低压传感器和多路阀的情形看是否出现故障。
This refers to a malfunction that occurs during the command transmission process, obstructing the delivery of command signals. Therefore, special attention should be given to checking the pump, low-pressure sensor, and multi-way valve for any signs of malfunction.
操作中心故障
Operational Center Malfunction
即挖掘机的指令发出中心故障,导致信号无法发出，这种情况一般比较复杂，也需要专业性的维修指导，各位挖机手可仔细检查相关电磁阀故障，是否阀芯发卡。
This pertains to a malfunction in the excavator's command issuing center, leading to the inability to send out signals. This situation is generally more complex and requires professional repair guidance. Excavator operators should carefully inspect related solenoid valve malfunctions and check whether the valve cores are stuck.
挖掘机整车动作缓慢
The Excavator Moves Slowly
液压系统是挖掘机的动力系统之一，如果挖掘机整车缓慢，应该检查液压系统，是否有日常的按时保养，以及液压油是否定时更换。过期的液压油不仅会影响挖掘机的效果性能，更会腐蚀挖掘机的液压壁。同时还应该检查液压油路和回油滤芯是否有堵塞现象，若有堵塞，则应该清理油路，严重时应更换零部件。
The hydraulic system is one of the power systems of the excavator. If the excavator is moving slowly, you should check the hydraulic system to see if it's well maintained and if the hydraulic oil is changed regularly. Expired hydraulic oil not only affects the effectiveness of the excavator but also corrodes its hydraulic components. Also, check if the hydraulic oil circuit and return oil filter element are blocked. If there is blockage, clean the circuit and replace the filter element if necessary.
发动机功率过低
Engine Power Too Low
同液压系统一样，发动机也是挖掘机的动力系统之一。发动机功率低会导致输出功率低下，进而挖掘机憋车，使挖掘机整车行动缓慢。
Similar to the hydraulic system, the engine is also one of the power systems of the excavator. If the engine power is low, it will lead to reduced output power and slow movement of the excavator. Check if the engine is running at normal power and ensure proper maintenance.
液压泵输出不足，这属于液压系统的传导故障之一，挖掘机手可进入服务诊断系统进行相关的压力测试，看是否因为液压泵的传导导致的挖掘机动作缓慢。
If the hydraulic pump output is insufficient, it's one of the transmission faults in the hydraulic system. Operators can enter the service diagnostic system for pressure testing to identify whether slow excavator movements are due to poor conduction caused by the hydraulic pump.
Slow Movements Due to Overheating
检查使用的燃油是否符合挖掘机的要求，若燃油太久没有更换，或者油品过脏，都需要更换燃油。同时若进油滤网附有铜屑，会刮伤主泵形成磨损，此时要清理滤网。
Check if the fuel used complies with the requirements of the excavator. If the fuel hasn't been changed for a long time or if it's too dirty, it needs to be replaced. If there are copper shavings attached to the oil filter, it might scratch the main pump and cause wear, so it's important to clean the filter.
滤芯阻塞
Blocked Filter Elements
滤芯阻塞会导致油路不顺，因此检查时需查看先导滤芯、回油滤芯、吸油滤芯是否被堵塞，若滤芯堵塞，则需清理堵塞物质，严重时需更换滤芯。
Blocked filter elements can lead to oil circuit blockage. Therefore, it's necessary to check whether the pilot filter element, return filter element, and suction filter element are clogged. If they are, clean the blockage or replace the filter element if needed.
主泵调理器
Main Pump Regulator
主泵调理器的活塞上沾上泥巴，挖掘机日常工作大部分时间都是和泥土打交道，因此活塞沾上泥巴也在所难免，但是活塞阻塞会导致主泵的泵压降低,输出动力减少，使挖掘机动作缓慢。因此挖掘机日常检修维护时，要清理各个部位的泥巴。
If the piston of the main pump regulator is covered with mud, it's inevitable given the excavation work often involves soil. However, a blocked piston can lead to a decrease in pump pressure and output power, causing slow excavator movements. Therefore, during routine maintenance, various parts should be cleaned of mud.
挖掘机动作缓慢问题，肯定让老板们十分不痛快，但无疑这也是挖掘机给大家的一个信号，这个时候，一定要细心地检查挖机故障。从这几个方面全面检修挖掘机，让我们的挖掘机摆脱“痴呆症”！
The issue of slow excavator movements might make operators unhappy, but it undoubtedly serves as a signal from the excavator. At such times, it's essential to carefully inspect excavator malfunctions. Comprehensive inspection and maintenance from various aspects will help excavators overcome their "dementia"!
