在濟南的工程建設中，壓路機作為關鍵設備，其發(fā)動機的性能直接影響施工效率和租賃設備的使用壽命。對于出租的壓路機而言，發(fā)動機保養(yǎng)尤為重要，既能減少故障停機時間，又能保障設備在不同施工環(huán)境下的穩(wěn)定運行，降低維修成本。

　　In the engineering construction in Jinan, the roller is a key equipment, and the performance of its engine directly affects the construction efficiency and the service life of the leased equipment. For rental rollers, engine maintenance is particularly important, as it can reduce downtime due to malfunctions and ensure stable operation of the equipment in different construction environments, thereby reducing maintenance costs.

　　燃油系統(tǒng)的保養(yǎng)是發(fā)動機正常運轉的基礎。壓路機發(fā)動機多以柴油為燃料，需使用符合標號的清潔柴油，避免因燃油雜質過多堵塞噴油嘴和燃油泵。在濟南的多雨季節(jié)，應定期排放油箱底部的積水和沉淀物，防止水分進入燃油系統(tǒng)導致部件銹蝕。燃油濾清器需按照使用周期及時更換，濾芯堵塞會影響燃油供給，導致發(fā)動機動力下降。加油時要注意清潔，避免將雜質帶入油箱，同時油箱應保持一定油量，避免油箱內壁因空蕩而銹蝕，影響燃油質量。

　　The maintenance of the fuel system is the foundation for the normal operation of the engine. Road roller engines often use diesel as fuel and require the use of clean diesel that meets the specified standards to avoid clogging of fuel injectors and fuel pumps due to excessive fuel impurities. During the rainy season in Jinan, it is necessary to regularly drain the accumulated water and sediment at the bottom of the fuel tank to prevent moisture from entering the fuel system and causing component corrosion. The fuel filter needs to be replaced in a timely manner according to its usage cycle. If the filter element is clogged, it will affect the fuel supply and cause a decrease in engine power. When refueling, pay attention to cleanliness to avoid bringing impurities into the fuel tank. At the same time, the fuel tank should maintain a certain amount of fuel to prevent the inner wall of the tank from rusting due to empty space, which affects fuel quality.

　　潤滑系統(tǒng)的保養(yǎng)能減少發(fā)動機部件的磨損。定期檢查機油的油位和質量，油位過低會導致潤滑不良，過高則會增加發(fā)動機負荷，甚至引發(fā)燒機油現象。根據壓路機的使用強度和環(huán)境溫度，選擇合適粘度的機油，并按照規(guī)定周期更換，更換時需將舊機油徹底放凈，避免新舊機油混合影響潤滑效果。機油濾清器也需同步更換，防止濾芯內的雜質進入潤滑系統(tǒng)。對于發(fā)動機的氣門、活塞等關鍵部位的潤滑點，應定期加注潤滑脂，確保活動部件靈活運轉，減少機械磨損。

　　The maintenance of lubrication system can reduce the wear of engine components. Regularly check the oil level and quality of the engine oil. A low oil level can lead to poor lubrication, while a high oil level can increase engine load and even cause oil burning. According to the usage intensity and ambient temperature of the road roller, choose the appropriate viscosity of engine oil, and replace it according to the prescribed cycle. When replacing, the old engine oil should be completely drained to avoid mixing new and old engine oil and affecting the lubrication effect. The oil filter also needs to be replaced synchronously to prevent impurities in the filter element from entering the lubrication system. For the lubrication points of key parts such as valves and pistons in the engine, lubricating grease should be regularly added to ensure the flexible operation of moving parts and reduce mechanical wear.

　　冷卻系統(tǒng)的保養(yǎng)可避免發(fā)動機過熱。濟南夏季氣溫較高，壓路機長時間作業(yè)易導致發(fā)動機溫度過高，需定期檢查冷卻液液位，不足時及時添加，且冷卻液應使用正規(guī)廠家生產的防凍液，避免用水直接替代，防止水垢生成和冬季凍裂。散熱器表面要保持清潔，及時清理灰塵、柳絮等雜物，保證散熱效果，避免因散熱不良導致發(fā)動機過熱。冷卻風扇和水泵的工作狀態(tài)也需定期檢查，風扇皮帶松緊度要適宜，過松會影響散熱，過緊則易導致皮帶磨損斷裂，水泵葉輪若出現磨損應及時更換，防止冷卻液循環(huán)不暢。

　　The maintenance of the cooling system can prevent the engine from overheating. The temperature in Jinan is relatively high in summer, and prolonged operation of the road roller can easily lead to high engine temperature. It is necessary to regularly check the coolant level and add it in a timely manner when it is insufficient. The coolant should use antifreeze produced by regular manufacturers to avoid direct replacement with water and prevent scale formation and winter frost cracking. The surface of the radiator should be kept clean, and dust, willow fluff, and other debris should be promptly removed to ensure effective heat dissipation and avoid engine overheating caused by poor heat dissipation. The working status of the cooling fan and water pump also needs to be checked regularly. The tightness of the fan belt should be appropriate. If it is too loose, it will affect heat dissipation, and if it is too tight, it is easy to cause belt wear and breakage. If the impeller of the water pump is worn, it should be replaced in time to prevent poor circulation of the coolant.

　　進氣系統(tǒng)的保養(yǎng)關系到發(fā)動機的燃燒效率。空氣濾清器是防止灰塵進入發(fā)動機的重要屏障，濟南部分施工場地揚塵較大，需縮短空氣濾清器的檢查和更換周期，濾芯表面的灰塵可通過壓縮空氣吹凈，但破損的濾芯必須立即更換，否則灰塵進入氣缸會加劇活塞和缸套的磨損。進氣管路要檢查是否有漏氣現象，漏氣會導致發(fā)動機進氣量不足，燃燒不充分，出現動力下降、油耗增加等問題，影響壓路機的作業(yè)效率。

　　The maintenance of the intake system is related to the combustion efficiency of the engine. The air filter is an important barrier to prevent dust from entering the engine. Some construction sites in Jinan have high levels of dust, so it is necessary to shorten the inspection and replacement cycle of the air filter. The dust on the surface of the filter element can be blown away by compressed air, but damaged filter elements must be replaced immediately, otherwise dust entering the cylinder will aggravate the wear of the piston and cylinder liner. The intake pipeline should be checked for any air leaks, which can lead to insufficient engine intake, insufficient combustion, decreased power, increased fuel consumption, and other problems, affecting the efficiency of the road roller.

　　日常檢查與定期維護相結合，能及時發(fā)現潛在故障。啟動發(fā)動機前，檢查發(fā)動機艙內的管線連接是否牢固，有無松動、破損情況，如油管、水管的接頭處是否滲漏。啟動后聽發(fā)動機運轉聲音是否正常，有無異響，觀察儀表盤上的水溫、油壓等指示燈是否正常。作業(yè)結束后，檢查發(fā)動機表面有無油污、冷卻液滲漏痕跡，清理發(fā)動機艙內的雜物。對于長期停放的出租壓路機，應定期啟動發(fā)動機，讓其怠速運轉一段時間，防止部件因長期靜置而生銹粘連，同時保持電瓶電量充足。

　　Combining daily inspections with regular maintenance can promptly detect potential faults. Before starting the engine, check whether the pipeline connections in the engine compartment are secure, whether they are loose or damaged, such as whether there is leakage at the joints of oil and water pipes. After starting, listen to the engine running sound to see if there is any abnormal noise, and observe whether the water temperature, oil pressure, and other indicator lights on the dashboard are normal. After the homework is completed, check the surface of the engine for oil stains and coolant leakage marks, and clean the debris in the engine compartment. For long-term parked rental rollers, the engine should be started regularly and allowed to idle for a period of time to prevent components from rusting and sticking due to prolonged standing, while maintaining sufficient battery power.
