Three precautions for maintenance of boarding axle

隨著社會的快速發(fā)展，對于機械化施工企業(yè)來說，液壓機械的好壞是企業(yè)正常生產(chǎn)的直接因素。 在液壓驅(qū)動的建筑機械的情況下，液壓系統(tǒng)的正常操作是其良好技術(shù)條件的主要指標(biāo)。 合格的液壓油是液壓系統(tǒng)可靠運行的保證。 適當(dāng)?shù)木S護(hù)是液壓系統(tǒng)可靠運行的基礎(chǔ)。 為此，我根據(jù)工作實踐，對一般工作環(huán)境中工程機械液壓系統(tǒng)的維護(hù)進(jìn)行了粗略的討論。

With the rapid development of society, the quality of hydraulic machinery is a direct factor for the normal production of mechanized construction enterprises. In the case of hydraulic driven construction machinery, the normal operation of the hydraulic system is the main indicator of its good technical conditions. Qualified hydraulic oil is the guarantee of reliable operation of hydraulic system. Proper maintenance is the foundation of reliable operation of hydraulic system. Therefore, according to my work practice, I have a rough discussion on the maintenance of the hydraulic system of construction machinery in the general working environment.

1.選擇液壓油

1. select hydraulic oil

液壓油用作液壓系統(tǒng)中的壓力，潤滑，冷卻和密封。 液壓油選擇不良是液壓系統(tǒng)早期失效和耐久性的主要原因。 液壓油應(yīng)根據(jù)隨機“使用說明”中規(guī)定的等級進(jìn)行選擇。 在特殊情況下使用替代油時，其性能應(yīng)與原始等級的性能相同。 不同等級的液壓油不能混合，以防止化學(xué)反應(yīng)和液壓油的性能變化。 深棕色，乳白色，有氣味的液壓油是一種變質(zhì)油，不能使用。

Hydraulic oil is used for pressure, lubrication, cooling and sealing in the hydraulic system. Poor selection of hydraulic oil is the main reason for early failure and durability of hydraulic system. The hydraulic oil shall be selected according to the grade specified in the accompanying "instructions for use". When alternative oil is used under special circumstances, its performance shall be the same as that of the original grade. Different grades of hydraulic oil shall not be mixed to prevent chemical reaction and performance change of hydraulic oil. The dark brown, milky white and odorous hydraulic oil is a deteriorated oil and cannot be used.

2.防止雜質(zhì)進(jìn)入

2. prevent impurities from entering

清潔液壓油是液壓系統(tǒng)的生命。 液壓系統(tǒng)中有許多連接部件，有些具有阻尼孔，有些具有間隙。 如果固體雜質(zhì)侵入，將導(dǎo)致意外的應(yīng)變，卡片發(fā)出，油路堵塞等，這將危及液壓系統(tǒng)的運行。 通常，固體雜質(zhì)侵入液壓系統(tǒng)的方式是：液壓油是不潔凈的; 加油工具是不潔凈的; 加油，維修和保養(yǎng)是無意的; 液壓元件脫落。 可以防止固體雜質(zhì)從以下方面侵入系統(tǒng)：

Cleaning hydraulic oil is the life of hydraulic system. There are many connecting parts in the hydraulic system, some with damping holes and some with clearances. If solid impurities invade, it will cause unexpected strain, card issue, oil circuit blockage, etc., which will endanger the operation of the hydraulic system. Generally, the ways in which solid impurities invade the hydraulic system are as follows: the hydraulic oil is unclean; Refueling tools are not clean; Refueling, repair and maintenance are unintentional; Hydraulic components fall off. It can prevent solid impurities from invading the system from the following aspects:

3.液壓清潔

3. hydraulic cleaning

清潔油使用與系統(tǒng)相同的液壓油。 油溫在45到80°C之間。 盡可能使用大流量從系統(tǒng)中去除雜質(zhì)。 液壓系統(tǒng)應(yīng)清洗三次以上。 每次清潔后，油在熱時會從系統(tǒng)中排出。 清潔后，清潔過濾器，更換新過濾器，然后添加新油。

The cleaning oil uses the same hydraulic oil as the system. The oil temperature is between 45 and 80 ° C. Use as much flow as possible to remove impurities from the system. The hydraulic system shall be cleaned more than three times. After each cleaning, the oil will drain from the system when it is hot. After cleaning, clean the filter, replace it with a new one, and then add new oil.
