怎么解决挖掘机动作慢的问题

日期:2018-10-15   来源:http://www.dyqicheng.com/
有人说,自己的挖掘机工作一段时间后,动作很缓慢,这是为什么呢?挖掘机动作慢,小编带领挖掘机手学会找原因,下面让我们一起了解造成挖掘机动作缓慢的几个原因。
Some people say that their excavators work for a period of time, the action is very slow, this is why? The excavator is slow, small editor led the excavator hand to learn to find the reasons, let us understand the following causes of the excavator slow action.
挖机动作慢
Slow digging
一、如果是操作行走、反转、抬大小臂、收回挖斗等单一作业时,速度比较慢。
First, if it is a single operation, such as walking, inversion, lifting arm and bucket recovery, the speed is relatively slow.
原因如下:
The reasons are as follows:
挖掘机相关组件的溢流阀压力过低,需进行测试
The relief valve pressure of the excavator related components is too low to be tested.
泵、低压传感器、多路阀故障
Failure of pump, low pressure sensor and multi way valve
相关电磁阀故障,阀芯发卡。
Related solenoid valve failure, spool issuing card.
二、如果是挖机全车/整车动作慢。
Two, if it is a digging machine, the whole vehicle / vehicle is slow.
需要检查下:
Need to check:
是否按时保养,液压油是否没有按时更换;液压油路是否堵塞,请检查在怠速时的系统压力,检查回油滤芯是否有堵塞的现象
加长臂挖掘机出租
Whether it is maintained on time, whether the hydraulic oil is not replaced on time, whether the hydraulic oil circuit is blocked, please check the system pressure at idle speed, check whether the filter element is blocked.
发动机的输出功率过低,动力不足请结合DX数据分析发动机的输出情况,所有气缸是否能够同时工作;检查发动机有无黑烟出现,如果喷油嘴磨损严重,也会引起发动机功率下降
If the output power of the engine is too low and the power is insufficient, please analyze the output of the engine with DX data to see if all the cylinders can work at the same time; check if the engine has black smoke, if the nozzle is worn seriously, it will also cause engine power decline
液压泵输出不足,进入服务诊断系统可进行相关压力的测试
The output of the hydraulic pump is insufficient, and the service diagnostic system can be tested for related pressure.
先导压力不足引起开启阀芯压力不足,造成流量不足,造成动作慢
Insufficient pilot pressure causes insufficient pressure to open the spool, resulting in insufficient flow and slow action.
电路相关问题:挖掘机CPU、高低压传感器、电磁阀及线路故障。
Circuit related problems: Excavator CPU, high and low voltage sensors, solenoid valves and line failures.
三、如果冷机正常,热机动作慢
Three, if the refrigerator is normal, the heat engine is slow.
首先要考虑到油品太脏,需更换;检查进油滤网是否有铜屑,造成主泵磨损,需拆解查看
First of all, consider the oil is too dirty, need to be replaced; check whether there is copper filings in the oil filter screen, causing wear and tear of the main pump, need to disassemble to check
先导滤芯、回油滤芯、吸油滤芯被堵塞
Pilot filter element, oil return filter and oil absorption filter are blocked.
主泵调理器伺服活塞上有油泥,斜盘不能调理,主泵总在小排量作业,流量小。
There is mud on the servo piston of the main pump conditioner. The swash plate can not be adjusted. The main pump always works in small displacement and the flow rate is small.
