引言 | Introduction

定期和正確的保養(yǎng)可以顯著延長二手挖掘機的使用壽命，提高其工作效率，并減少故障發(fā)生的概率。本文將詳細介紹如何通過日常維護、定期檢查和專業(yè)保養(yǎng)來保持二手挖掘機的最佳狀態(tài)。

Regular and proper maintenance can significantly extend the lifespan of used excavators, enhance their working efficiency, and reduce the likelihood of breakdowns. This article will detail how to maintain used excavators in top condition through daily maintenance, regular inspections, and professional servicing.

一、日常維護 | Daily Maintenance

1. 檢查液壓系統(tǒng) | Check the Hydraulic System:

• 液壓油位 | Hydraulic Oil Level: 每天檢查液壓油位，確保在正常范圍內(nèi)。低液壓油位可能導(dǎo)致系統(tǒng)損壞。

• Hydraulic Oil Level: Check the hydraulic oil level daily to ensure it is within the normal range. Low hydraulic oil levels can cause system damage.

• 泄漏檢查 | Leak Inspection: 檢查液壓管道和接頭是否有泄漏，及時修復(fù)任何泄漏點。

• Leak Inspection: Inspect hydraulic lines and fittings for leaks and repair any leakage points promptly.

2. 清潔設(shè)備 | Clean the Equipment:

• 外部清潔 | Exterior Cleaning: 定期清潔挖掘機外部，特別是發(fā)動機、冷卻器和散熱器，以防止灰塵和雜物積聚。

• Exterior Cleaning: Regularly clean the exterior of the excavator, especially the engine, cooler, and radiator, to prevent dust and debris buildup.

• 駕駛室清潔 | Cab Cleaning: 保持駕駛室清潔，確保操作員有一個舒適的工作環(huán)境。

• Cab Cleaning: Keep the cab clean to ensure a comfortable working environment for the operator.

二、定期檢查 | Regular Inspections

1. 發(fā)動機檢查 | Engine Inspection:

• 機油更換 | Oil Change: 根據(jù)制造商的建議定期更換發(fā)動機機油和濾清器，確保發(fā)動機平穩(wěn)運行。

• Oil Change: Regularly change the engine oil and filters as per the manufacturer's recommendations to ensure smooth engine operation.

• 皮帶和軟管 | Belts and Hoses: 檢查皮帶和軟管是否有磨損或裂紋，及時更換損壞的部件。

• Belts and Hoses: Inspect belts and hoses for wear or cracks and replace damaged parts promptly.

2. 底盤檢查 | Undercarriage Inspection:

• 履帶張力 | Track Tension: 定期檢查和調(diào)整履帶張力，確保其在正確的范圍內(nèi)，以防止過度磨損。

• Track Tension: Regularly check and adjust track tension to ensure it is within the correct range to prevent excessive wear.

• 螺栓和緊固件 | Bolts and Fasteners: 檢查底盤部件的螺栓和緊固件是否松動，確保所有連接牢固。

• Bolts and Fasteners: Check the bolts and fasteners on the undercarriage components to ensure all connections are tight.

三、專業(yè)保養(yǎng) | Professional Servicing

1. 定期專業(yè)檢查 | Regular Professional Inspections:

• 綜合檢查 | Comprehensive Inspections: 每年至少進行一次由專業(yè)技術(shù)人員進行的全面檢查，評估設(shè)備的整體狀況。

• Comprehensive Inspections: Have a comprehensive inspection conducted by professional technicians at least once a year to assess the overall condition of the equipment.

• 診斷測試 | Diagnostic Testing: 使用專業(yè)診斷設(shè)備檢測挖掘機的電子和機械系統(tǒng)，確保所有部件正常工作。

• Diagnostic Testing: Use professional diagnostic equipment to test the excavator's electronic and mechanical systems to ensure all components are working properly.

2. 專業(yè)維修 | Professional Repairs:

• 及時維修 | Timely Repairs: 發(fā)現(xiàn)問題時立即進行維修，避免小問題發(fā)展成大故障。

• Timely Repairs: Conduct repairs promptly when issues are identified to prevent small problems from developing into major breakdowns.

• 更換老化部件 | Replace Aging Parts: 根據(jù)使用情況和專業(yè)建議，定期更換老化和磨損的部件。

• Replace Aging Parts: Regularly replace aging and worn-out parts based on usage and professional recommendations.

結(jié)論 | Conclusion
