液壓萬能試驗機在建筑資料，金屬資料的力學檢測上，由于其杰出的操控功能和試驗精度，得到了廣泛的運用。在大型鋼鐵企業(yè)，及質檢單位實驗室里，試驗機往往是多臺進行高負荷任務。

Hydraulic universal testing machine has been widely used in mechanical testing of building materials and metal materials due to its outstanding control function and test accuracy. In large iron and steel enterprises and laboratories of quality inspection units, test machines often carry out high-load tasks.

1、液壓油

1. Hydraulic oil

必須常常查看油箱液面并及時補油；普通要每運用2000至4000小時換一次油；但是最重要的是油溫不得超越70℃，在油溫超越60℃時必須翻開冷卻體系。

It is necessary to check the tank liquid level frequently and replenish oil in time; oil should be changed every 2000 to 4000 hours; but the most important thing is that the oil temperature should not exceed 70 (?) C, and the cooling system must be turned over when the oil temperature exceeds 60 (?).

2、電液伺服萬能試驗機緊固件要定時進行鎖緊

2. The fastener of electro-hydraulic servo universal testing machine should be locked regularly.

試樣拉斷后的振蕩常常會使一些緊固件退松，一定要定時進行巡檢(正常運用三十個任務日左右)，以避免由于緊固件松動造成大的丟失。

The oscillation after sample breaking often causes some fasteners to loosen. It is necessary to inspect them regularly (about 30 working days) in order to avoid large losses due to loosening of fasteners.

3、潤滑油

3. Lubricants

電液伺服萬能試驗機絲杠及傳動局部要定時涂潤滑油，避免發(fā)生干沖突。

The screw and transmission parts of the electro-hydraulic servo universal testing machine should be regularly lubricated to avoid dry conflict.

4、過濾器

4. Filter

關于不帶阻塞指示器的過濾器，普通每隔6個月要替換一次。關于帶阻塞指示器的過濾器，要不斷監(jiān)督，當指示器報警后必須當即替換。

For filters without blocking indicators, they are usually replaced every six months. The filter with blocking indicator should be monitored continuously and replaced immediately after the indicator alarms.

5、蓄能器

5. Accumulator

有些電液伺服萬能試驗機上配有蓄能器，必須包管蓄能器的壓力處于正常任務狀況，若是發(fā)現(xiàn)壓力不敷，需求立刻彌補壓力；只準向蓄能器充入氮氣。

Some electro-hydraulic servo universal testing machines are equipped with accumulators, which must ensure that the accumulator's pressure is in normal working condition. If the pressure is found to be insufficient, the pressure should be compensated immediately; only nitrogen should be charged to the accumulator.

6、元器件定時巡檢

6. Regular inspection of components

一切壓力操控閥、流量操控閥、泵調節(jié)器以及壓力繼電器、行程開關、熱繼電器之類的信號設備，都要進行定時查看。

All pressure control valves, flow control valves, pump regulators and pressure relays, stroke switches, thermal relays and other signal equipment, should be regularly checked.

7、冷卻器

7. Cooler

選用風冷的冷卻器的積垢要定時整理；選用水冷的要定時調查冷卻銅管有沒有決裂漏水的表象。

The scale of air-cooled cooler should be regularly sorted out, and water-cooled copper pipe should be regularly investigated for cracking and leakage.
