冷再生机的使用不仅可以节约能源和资源，降低材料、人工费，节省运输费，对于施工又可以延长施工季节，几乎不受阴湿或低温季节影响。下面冷再生机租赁人员为您讲解下冷再生机“液压系统”的更换与保养。

The use of the cold regenerator can not only save energy and resources, reduce material and labor costs, save transportation costs, but also extend the construction season for construction, almost not affected by wet or cold seasons. The rental personnel of the cold regenerator will explain the replacement and maintenance of the "hydraulic system" of the cold regenerator.

更换条件及标准：

Replacement conditions and standards:

冷再生机在施工过程中负荷较大、液压系统温度较高，为使泵和马达等液压元件系统中的液压油黏度处于佳范围，建议用户使用HV46#及以上低温冷凝抗磨液压油。

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 pump, motor and other hydraulic component systems within a good range, users are recommended to use HV46 # and above low-temperature condensate anti-wear hydraulic oil.

根据工程机械设备对液压系统的要求，初次对液压系统和滤芯的保养为500小时，考虑油质及费用问题，初次保养方案是将油品进行过滤，只更换滤芯；从二次保养开始为1000h，因工作强度的大小不一样，可以根据油脂情况适当延长保养时间。

According to the requirements of engineering 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 plan 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 extended according to the grease condition.

若设备运转使用不足1000小时，因工作强度一般可不更换全部液压油，但需要放出样品，看颜色是否清亮，手感粘度是否可以，可采用过滤全部液压油后更换全部滤芯的方式进行保养。

If the equipment has been operated for less than 1000 hours, it is generally not necessary to replace all the hydraulic oil due to the working strength, but it is necessary to discharge the sample to see whether the color is clear and the hand viscosity is acceptable. The maintenance can be carried out by filtering all the hydraulic oil and replacing all the filter elements.

保养方案：

Maintenance plan:

①更换时机：设备运转结束后适当的温度下（50摄氏度以下）更换为佳时机。

① Time for replacement: The best time for replacement is at an appropriate temperature (below 50 ℃) after the equipment operation.

②更换液压油及滤芯应具备的场地条件及器具。

② The site conditions and instruments required for replacing hydraulic oil and filter element.

场地条件：平整清洁的地面（水泥地面好）。

Site conditions: flat and clean ground (good cement ground).

器具：三相电源、200L的油桶三个、滤油机一台（更换滤芯）、充足的液压油（HV46#）、滤芯一套、滤芯扳手1件。

Appliance: three-phase power supply, three 200L oil drums, one oil filter (filter element replacement), sufficient hydraulic oil (HV46 #), one set of filter element, and one filter element wrench.

③更换步骤：先将设备的液压油抽出。拆下全部液压油滤芯。将事先需要更换的钢管、胶管安装好。将新液压油通过滤油机注入。观察新的油位是否达到标准油位，直到达标为准。启动设备后，小负荷运转设备，使液压油均匀充满各部位液压件。

③ Replacement steps: first draw out the hydraulic oil of the equipment. Remove all hydraulic oil filter elements. Install the steel pipes and rubber hoses that need to be replaced in advance. Fill 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 small load to make the hydraulic oil evenly fill all parts of the hydraulic parts.
