二手挖掘機的保養和維修是確保設備高效運行和延長其使用壽命的關鍵。本文將介紹一些實用的保養和維修技巧，幫助您保持設備的最佳狀態，減少故障發生，提高工作效率。

Proper maintenance and repair of second-hand excavators are crucial to ensuring efficient operation and extending the equipment's lifespan. This article will introduce some practical maintenance and repair tips to help you keep the equipment in optimal condition, reduce the occurrence of breakdowns, and improve work efficiency.

一、日常保養

Daily Maintenance

1. 檢查液壓系統

• 每天檢查液壓油位，確保液壓油充足且干凈。定期更換液壓油和濾芯，防止系統污染和磨損。

• Check the hydraulic oil level daily to ensure it is sufficient and clean. Regularly replace hydraulic oil and filters to prevent system contamination and wear.

2. 檢查發動機

• 每天啟動前檢查發動機油位和冷卻液液位，確保發動機在正常工作溫度下運行。定期更換發動機油和空氣濾芯。

• Check the engine oil level and coolant level before starting each day to ensure the engine operates at normal working temperature. Regularly replace engine oil and air filters.

3. 檢查底盤

• 檢查底盤部件，如履帶、輪胎和懸掛系統，確保沒有明顯的磨損或損壞。及時更換磨損嚴重的部件。

• Inspect undercarriage components such as tracks, tires, and suspension systems to ensure there is no significant wear or damage. Replace severely worn components promptly.

二、定期維護

Regular Maintenance

1. 潤滑

• 定期潤滑所有運動部件，包括鉸接點、臂架和鏟斗，以減少摩擦和磨損，延長部件使用壽命。

• Regularly lubricate all moving parts, including pivot points, arms, and buckets, to reduce friction and wear, extending the lifespan of the components.

2. 清潔

• 定期清潔設備，特別是散熱器、發動機艙和液壓油箱，防止灰塵和雜物積聚，影響設備性能。

• Regularly clean the equipment, especially radiators, engine compartments, and hydraulic tanks, to prevent dust and debris buildup that could affect equipment performance.

3. 檢查電氣系統

• 定期檢查電氣系統的連接和電線，確保沒有松動或破損。及時更換老化的電線和接頭。

• Regularly inspect electrical system connections and wires to ensure there are no loose or damaged parts. Replace aging wires and connectors promptly.

三、季節性保養

Seasonal Maintenance

1. 冬季保養

• 在冬季，確保使用適合低溫的液壓油和發動機油。每天工作結束后排空液壓系統中的積水，防止結冰損壞系統。

• In winter, ensure the use of hydraulic oil and engine oil suitable for low temperatures. Drain water from the hydraulic system daily after work to prevent ice damage.

2. 夏季保養

• 在夏季，定期檢查和清潔散熱器，確保散熱良好。避免長時間高溫作業，防止發動機過熱。

• In summer, regularly check and clean radiators to ensure proper cooling. Avoid prolonged high-temperature operation to prevent engine overheating.

四、故障排除

Troubleshooting

1. 液壓系統故障

• 液壓系統故障通常表現為液壓油泄漏、液壓油溫度過高或液壓系統壓力不足。檢查液壓管道、密封件和液壓泵，找出故障原因并進行修復。

• Hydraulic system failures usually manifest as hydraulic oil leaks, high hydraulic oil temperature, or insufficient hydraulic system pressure. Check hydraulic pipes, seals, and hydraulic pumps to identify the cause of the failure and repair it.

2. 發動機故障

• 發動機故障通常表現為啟動困難、發動機過熱或異常噪音。檢查燃油系統、冷卻系統和發動機部件，找出故障原因并進行修復。

• Engine failures usually manifest as difficulty starting, engine overheating, or abnormal noise. Check the fuel system, cooling system, and engine components to identify the cause of the failure and repair it.

3. 電氣系統故障

• 電氣系統故障通常表現為電氣設備不工作或儀表盤無顯示。檢查電氣線路和接頭，找出故障原因并進行修復。

• Electrical system failures usually manifest as non-working electrical equipment or no display on the dashboard. Check electrical wiring and connectors to identify the cause of the failure and repair it.

五、專業保養服務

Professional Maintenance Services

1. 定期專業檢查

• 每年至少進行一次專業檢查，由專業技師對設備進行全面檢測和維護，發現潛在問題并及時解決。

• Conduct a professional inspection at least once a year, where professional technicians perform comprehensive checks and maintenance to identify and resolve potential issues.

2. 使用原廠配件

• 在更換部件時，盡量使用原廠配件，確保配件質量和設備兼容性，提高設備的可靠性和使用壽命。

• When replacing parts, use original manufacturer parts whenever possible to ensure quality and compatibility, enhancing equipment reliability and lifespan.
