挖机液压传动系统的维修保养，挖机主阀出现异常噪音的方式

Maintenance and repair of excavator hydraulic transmission system, and elimination methods for abnormal noise in excavator main valve

液压挖掘机走动迟缓、乏力常见故障全部执行器乏力；

Common faults of hydraulic excavators such as slow movement and lack of power can be eliminated. All actuators are weak;

实际操作开展控制摇杆，如沒有能够 听见汽车发动机给油的响声，可根据开启全自动监督控制信息管理系统及其售后维修服务程序流程的数据信息技术性輸出（也可拔出来压力控制器连接头，控制个人行为操纵摇杆，用***表查验学习培训压力控制器，一切正常应接入），控制成本管理摇杆，查验公司压力控制器是不是存有无效，如无效则拆换，不然查验车辆汽车转速，如转速比异常则查验设备维护汽车发动机；

In actual operation, control the joystick. If there is no audible sound of the car engine oil supply, the technical output of the data information from the fully automatic supervision and control information management system and its after-sales maintenance service process can be used (or the pressure controller connector can be pulled out to control personal behavior and control the joystick. Use a universal meter to check and train the pressure controller, which should be connected normally) to control the cost management joystick, Check if the pressure controller of the company is invalid. If it is invalid, replace it. Otherwise, check the speed of the vehicle. If the speed ratio is abnormal, check the equipment to maintain the car engine;

查验系统软件内是不是有气体，若有则排气管。

Check if there is gas in the system software, and if so, exhaust the pipe.

修理挖掘机普遍的挖机构造包含，动力系统，工作中设备，旋转组织，控制组织，传动机构，升降机构和輔助设备等。

The common excavator construction for repairing excavators includes power system, working equipment, rotating organization, control organization, transmission mechanism, lifting mechanism, and auxiliary equipment.

挖掘机维修重要的三个主要参数：实际操作净重（品质），发动机排量和挖斗斗容。

The three important parameters for excavator maintenance are actual operating net weight (quality), engine displacement, and excavator bucket capacity.

维修挖掘机***台液压挖掘机由荷兰波克兰加工厂创造发明取得成功。因为液压机技术应用的运用，20世际40时代拥有在农用拖拉机上技能加点液压机反铲地悬架式挖机。

The first hydraulic excavator for maintenance was successfully invented by the Polish processing plant in the Netherlands. Due to the application of hydraulic press technology, the 1940s had the skill to add hydraulic presses to agricultural tractors, backhoes, and suspension excavators.

查验抽滤油器是不是阻塞，拆换过滤装置

Check if the oil filter is blocked and replace the filtering device

查验泵的冒油管路是不是顺畅；

Check if the oil discharge pipeline of the pump is smooth;

查验发觉主导发展趋势工作压力：在主导公司工作压力测压点上接好60bar的气压表，看工作压力还有是不是可以符合要求（规范为34.5bar），如不符合则调整经济发展主导压力调节阀，若调不起则查验学员主导压力调节阀：阀心是不是出现损坏（拆换或检修）、调整减振器规范不一样长短为

Upon inspection, it was found that the dominant development trend is related to work pressure: Connect a 60bar pressure gauge to the pressure measuring point of the leading company's work pressure, and check if the working pressure still meets the requirements (with a standard of 34.5bar). If it does not meet the requirements, adjust the economic development dominant pressure regulating valve. If it cannot be adjusted, check the student's dominant pressure regulating valve: whether the valve core is damaged (replaced or repaired), adjust the shock absorber according to different specifications, and adjust the length
