    加長臂挖掘機開展液壓機控制技術的維護保養

    日期:2023-12-28   來源:http://www.wbeye.com/

    挖機液壓傳動系統的維修保養,挖機主閥出現異常噪音的方式

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

    液壓挖掘機走動遲緩、乏力常見故障全部執行器乏力;

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

    實際操作開展控制搖桿,如沒有能夠 聽見汽車發動機給油的響聲,可根據開啟全自動監督控制信息管理系統及其售后維修服務程序流程的數據信息技術性輸出(也可拔出來壓力控制器連接頭,控制個人行為操縱搖桿,用***表查驗學習培訓壓力控制器,一切正常應接入),控制成本管理搖桿,查驗公司壓力控制器是不是存有無效,如無效則拆換,不然查驗車輛汽車轉速,如轉速比異常則查驗設備維護汽車發動機;

    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;

    查驗系統軟件內是不是有氣體,若有則排氣管。

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

    修理挖掘機普遍的挖機構造包含,動力系統,工作中設備,旋轉組織,控制組織,傳動機構,升降機構和輔助設備等。

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

    挖掘機維修重要的三個主要參數:實際操作凈重(品質),發動機排量和挖斗斗容。

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

    維修挖掘機***臺液壓挖掘機由荷蘭波克蘭加工廠創造發明取得成功。因為液壓機技術應用的運用,20世際40時代擁有在農用拖拉機上技能加點液壓機反鏟地懸架式挖機。

    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.

    查驗抽濾油器是不是阻塞,拆換過濾裝置

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

    查驗泵的冒油管路是不是順暢;

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

    查驗發覺主導發展趨勢工作壓力:在主導公司工作壓力測壓點上接好60bar的氣壓表,看工作壓力還有是不是可以符合要求(規范為34.5bar),如不符合則調整經濟發展主導壓力調節閥,若調不起則查驗學員主導壓力調節閥:閥心是不是出現損壞(拆換或檢修)、調整減振器規范不一樣長短為

    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
