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、液压油

1. Hydraulic oil

必须常常查看油箱液面并及时补油；普通要每运用2000至4000小时换一次油；但是最重要的是油温不得超越70℃，在油温超越60℃时必须翻开冷却体系。

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、电液伺服万能试验机紧固件要定时进行锁紧

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

试样拉断后的振荡常常会使一些紧固件退松，一定要定时进行巡检(正常运用三十个任务日左右)，以避免由于紧固件松动造成大的丢失。

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、润滑油

3. Lubricants

电液伺服万能试验机丝杠及传动局部要定时涂润滑油，避免发生干冲突。

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

4、过滤器

4. Filter

关于不带阻塞指示器的过滤器，普通每隔6个月要替换一次。关于带阻塞指示器的过滤器，要不断监督，当指示器报警后必须当即替换。

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

有些电液伺服万能试验机上配有蓄能器，必须包管蓄能器的压力处于正常任务状况，若是发现压力不敷，需求立刻弥补压力；只准向蓄能器充入氮气。

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、元器件定时巡检

6. Regular inspection of components

一切压力操控阀、流量操控阀、泵调节器以及压力继电器、行程开关、热继电器之类的信号设备，都要进行定时查看。

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、冷却器

7. Cooler

选用风冷的冷却器的积垢要定时整理；选用水冷的要定时调查冷却铜管有没有决裂漏水的表象。

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