路面冷再生機“液壓系統(tǒng)”的更換與保養(yǎng)常識
來源：http://www.kqj188.com/ 日期：2021-09-01 發(fā)布人：
一、更換條件及標準：
1、 Replacement conditions and standards:
冷再生機在施工過程中負荷較大、液壓系統(tǒng)溫度較高，為使泵和馬達等液壓元件系統(tǒng)中的液壓油黏度處于佳范圍，建議用戶使用HV46#及以上低溫冷凝抗磨液壓油。
During the construction of the cold regenerator, the load is large and the temperature of the hydraulic system is high. In order to keep the viscosity of the hydraulic oil in the hydraulic component system such as pump and motor in a good range, it is recommended that the user use hv46# and above low-temperature condensing anti-wear hydraulic oil.
根據(jù)工程機械設(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，考慮油質(zhì)及費用問題，初次保養(yǎng)方案是將油品進行過濾，只更換濾芯；從二次保養(yǎng)開始為1000h，因工作強度的大小不一樣，可以根據(jù)油脂情況適當延長保養(yǎng)時間。
According to the requirements of construction machinery and equipment for the hydraulic system, the initial maintenance of the hydraulic system and filter element is 500 hours. Considering the oil quality and cost, the initial maintenance scheme is to filter the oil and only replace the filter element; 1000h from the second maintenance. Due to different working intensity, the maintenance time can be appropriately extended according to the oil condition.
若設(shè)備運轉(zhuǎn)使用不足1000小時，因工作強度一般可不更換全部液壓油，但需要放出樣品，看顏色是否清亮，手感粘度是否可以，可采用過濾全部液壓油后更換全部濾芯的方式進行保養(yǎng)。
If the equipment is operated and used for less than 1000 hours, due to the working intensity, it is generally not necessary to replace all the hydraulic oil, but it is necessary to release the sample to see whether the color is clear and whether the hand feel viscosity is OK. The maintenance can be carried out by replacing all the filter elements after filtering all the hydraulic oil.
二、保養(yǎng)方案：
2、 Maintenance scheme:
①更換時機：設(shè)備運轉(zhuǎn)結(jié)束后適當?shù)臏囟认拢?0攝氏度以下）更換為好的時機。
① Replacement time: it is a good time to replace the equipment at an appropriate temperature (below 50 ℃) after the operation of the equipment.
②更換液壓油及濾芯應(yīng)具備的場地條件及器具。場地條件：平整清潔的地面。器具：三相電源、200L的油桶三個、濾油機一臺（更換濾芯）、充足的液壓油（HV46#）、濾芯一套、濾芯扳手1件。
② Site conditions and instruments for replacing hydraulic oil and filter element. Site conditions: flat and clean ground. Appliances: three-phase power supply, three 200L oil drums, one oil filter (replace filter element), sufficient hydraulic oil (hv46#), one set of filter element and one filter element wrench.
③更換步驟：先將設(shè)備的液壓油抽出。拆下全部液壓油濾芯。將事先需要更換的鋼管、膠管安裝好。將新液壓油通過濾油機注入。觀察新的油位是否達到標準油位，直到達標為準。啟動設(shè)備后，小負荷運轉(zhuǎn)設(shè)備，使液壓油均勻充滿各部位液壓件。
③ Replacement steps: first draw out the hydraulic oil of the equipment. Remove all hydraulic oil filter elements. Install the steel pipe and rubber hose that need to be replaced in advance. Inject new hydraulic oil through the oil filter. Observe whether the new oil level reaches the standard oil level until it reaches the standard. After starting the equipment, operate the equipment with a small load to make the hydraulic oil fill all parts of the hydraulic parts evenly.
