路面冷再生機(jī)液壓系統(tǒng)的更換與保養(yǎng)是確保其正常運行和延長使用壽命的重要環(huán)節(jié)。以下是一些關(guān)于路面冷再生機(jī)液壓系統(tǒng)更換與保養(yǎng)的常識：

　　The replacement and maintenance of the hydraulic system of the road surface cold recycling machine is an important part to ensure its normal operation and extend its service life. Here are some common knowledge about replacing and maintaining the hydraulic system of the road cold recycling machine:

　　一、液壓系統(tǒng)更換步驟

　　1、 Hydraulic system replacement steps

　　更換時機(jī)：

　　Replacement timing:

　　設(shè)備運轉(zhuǎn)結(jié)束后，在適當(dāng)?shù)臏囟认拢?0攝氏度以下）更換液壓油為最佳時機(jī)。

　　The best time to replace hydraulic oil is at an appropriate temperature (below 50 degrees Celsius) after the equipment is running.

　　場地條件與器具準(zhǔn)備：

　　Site conditions and equipment preparation:

　　場地條件：選擇平整清潔的地面（水泥地面最好）。

　　Site conditions: Choose a flat and clean ground (preferably cement ground).

　　器具：準(zhǔn)備三相電源、200L的油桶三個、濾油機(jī)一臺（用于更換濾芯）、充足的液壓油（建議使用HV46#及以上低溫冷凝抗磨液壓油）、濾芯一套、濾芯扳手1件。

　　Equipment: Prepare a three-phase power supply, three 200L oil drums, one oil filter (for replacing the filter element), sufficient hydraulic oil (recommended to use HV46 # and above low-temperature condensing anti-wear hydraulic oil), one set of filter elements, and one filter wrench.

　　更換步驟：

　　Replacement steps:

　　先將設(shè)備的液壓油抽出。

　　First, extract the hydraulic oil from the equipment.

　　拆下全部液壓油濾芯。

　　Remove all hydraulic oil filter elements.

　　將需要更換的鋼管、膠管安裝好。

　　Install the steel pipes and rubber hoses that need to be replaced.

　　將新液壓油通過濾油機(jī)注入。

　　Inject new hydraulic oil through the oil filter.

　　觀察新的油位是否達(dá)到標(biāo)準(zhǔn)油位，直到達(dá)標(biāo)為止。

　　Observe whether the new oil level reaches the standard oil level until it meets the standard.

　　啟動設(shè)備后，小負(fù)荷運轉(zhuǎn)設(shè)備，使液壓油均勻充滿各部位液壓件。

　　After starting the equipment, operate it under low load to evenly fill all hydraulic components with hydraulic oil.

　　二、液壓系統(tǒng)保養(yǎng)常識

　　2、 Common knowledge of hydraulic system maintenance

　　液壓油選擇與更換：

　　Hydraulic oil selection and replacement:

　　路面冷再生機(jī)在施工過程中負(fù)荷較大、液壓系統(tǒng)溫度較高，因此建議使用HV46#及以上低溫冷凝抗磨液壓油。

　　The road surface cold recycling machine has a high load and hydraulic system temperature during construction, so it is recommended to use HV46 # and above low-temperature condensing anti-wear hydraulic oil.

　　根據(jù)工程機(jī)械設(shè)備對液壓系統(tǒng)的要求，初次對液壓系統(tǒng)和濾芯的保養(yǎng)為500小時，初次保養(yǎng)方案是將油品進(jìn)行過濾，只更換濾芯；從第二次保養(yǎng)開始為1000小時，可根據(jù)油脂情況適當(dāng)延長保養(yǎng)時間。若設(shè)備運轉(zhuǎn)使用不足1000小時，但工作強(qiáng)度一般，可不更換全部液壓油，但需放出樣品檢查顏色是否清亮、手感粘度是否合適，可采用過濾全部液壓油后更換全部濾芯的方式進(jìn)行保養(yǎng)。

　　According to the requirements of engineering machinery equipment for hydraulic systems, the initial maintenance of the hydraulic system and filter element is 500 hours. The initial maintenance plan is to filter the oil and only replace the filter element; Starting from the second maintenance, it takes 1000 hours, and the maintenance time can be extended appropriately according to the condition of the grease. If the equipment has been running for less than 1000 hours but the working intensity is average, it is not necessary to replace all hydraulic oil. However, it is necessary to release a sample to check whether the color is clear and whether the hand feel and viscosity are appropriate. The maintenance can be carried out by filtering all hydraulic oil and replacing all filter elements.

　　定期啟動與檢查：

　　Regular start-up and inspection:

　　定期啟動機(jī)器并開啟機(jī)器上的所有液壓功能，讓液壓驅(qū)動元件定期工作，以防止相關(guān)的密封件因長時間的停放而損壞，以及油缸桿等金屬元件銹蝕等故障。

　　Regularly start the machine and activate all hydraulic functions on it, allowing the hydraulic drive components to work regularly to prevent damage to related seals due to prolonged parking, as well as rusting of metal components such as oil cylinder rods.

　　在使用過程中，應(yīng)經(jīng)常檢查液壓油的油位、油質(zhì)和油溫，確保液壓系統(tǒng)在正常狀態(tài)下工作。

　　During use, the oil level, quality, and temperature of the hydraulic oil should be checked regularly to ensure that the hydraulic system is working properly.

　　清潔與防護(hù)：

　　Cleaning and protection:

　　保持液壓系統(tǒng)清潔，防止污染物進(jìn)入油箱和液壓管路。

　　Keep the hydraulic system clean to prevent contaminants from entering the oil tank and hydraulic pipelines.

　　盡可能地將所有的油缸桿縮到液壓油缸油腔內(nèi)，以更好地保護(hù)油缸桿的表面。

　　As much as possible, retract all cylinder rods into the hydraulic cylinder oil chamber to better protect the surface of the cylinder rods.

　　專業(yè)維修與保養(yǎng)：

　　Professional maintenance and upkeep:

　　液壓系統(tǒng)的維修和保養(yǎng)應(yīng)由專業(yè)人員進(jìn)行，以確保操作正確、安全。

　　The maintenance and upkeep of hydraulic systems should be carried out by professionals to ensure correct and safe operation.

　　在維修和保養(yǎng)過程中，應(yīng)嚴(yán)格遵守相關(guān)操作規(guī)程和安全規(guī)定。

　　During the repair and maintenance process, relevant operating procedures and safety regulations should be strictly followed.

　　綜上所述，路面冷再生機(jī)液壓系統(tǒng)的更換與保養(yǎng)需要遵循一定的步驟和常識，以確保其正常運行和延長使用壽命。在更換液壓油時，應(yīng)注意選擇合適的液壓油、掌握更換時機(jī)和步驟；在保養(yǎng)過程中，應(yīng)定期檢查液壓油、保持系統(tǒng)清潔、定期啟動機(jī)器并檢查液壓功能等。同時，液壓系統(tǒng)的維修和保養(yǎng)應(yīng)由專業(yè)人員進(jìn)行，以確保操作正確、安全。

　　In summary, the replacement and maintenance of the hydraulic system of the road cold recycling machine need to follow certain steps and common sense to ensure its normal operation and extend its service life. When replacing hydraulic oil, attention should be paid to selecting the appropriate hydraulic oil, mastering the timing and steps of replacement; During the maintenance process, it is necessary to regularly check the hydraulic oil, keep the system clean, start the machine regularly, and check the hydraulic function. Meanwhile, the maintenance and upkeep of the hydraulic system should be carried out by professionals to ensure correct and safe operation.
