电脑全自动恒应力压力试验机使用与操作注意事项:

★ 使用前应先检查油箱内的油液是否充足，可察看右侧面油标，如不足，则应打开后箱板向油箱内添加之，至液面在油标处为宜。

★检查各油灌接头和紧固件是否松动，如有松动则拧紧之。检查防尘罩应完整无损。检查电气接地、保险熔丝等安全防护措施是否有效。

★一次使用时，应先将回油阀打开，关闭回油阀，接通电源，按下启动按钮，油泵开始工作，然后关闭回油阀，徐徐打开送不油阀，活塞上升一段距离，有无卡住等现象。如有，则应卸荷、停机检查，并排除之。打开回油阀，活塞则下降到原位。

★ 将试件表面擦拭干净，检查外观有无明显缺陷，如有能影响试验数值者，须更换无损试件。

★按试件下压板定位线框放在下压板正中，并按试件大小，转动手轮和丝杠，调节上压板至适当位置。

★接通测控系统电源(开关在测控箱背后)，按操作步骤进行清零以及时钟修改等各有关数据的输入。

★按下启动按钮，关闭回油阀，调控送油阀，按需要速率平稳进行加荷试验，及至试件被压碎，负荷下降。随即打开回油阀，使油液迅速流回油箱。

★试验结束时，按面板上“打印”键。打印机即可打印输出该次的试验报告。

★ 操作时，下压板上升高度不得超过4cm(或立柱上标志线)，以免发生意外。

★ 操作中禁止手等人体任何部分置于上下压板之间，并注意试件在破碎时碎片崩出伤人。

★试后随即清除破碎试块，以待下次试验。当不再做试验时，要打开回油阀，关闭送油阀，切断电源。

Precautions for use and operation of automatic concrete pressure testing machine

★ Before use, check whether the oil in the fuel tank is sufficient. You can check the oil level on the right side. If it is insufficient, you should open the rear tank plate and add it to the fuel tank.

★ Check whether the oil fittings and fasteners are loose, and tighten them if they are loose. Check that the dust cover is intact. Check whether the safety protection measures such as electrical grounding and fuse are effective.

★ When used once, the oil return valve should be opened, closed, and the power should be turned on. Press the start button to start the oil pump, then close the oil return valve, slowly open the oil delivery valve, and the piston rises a distance. No jams and so on. If there is, it should be unloaded, stopped and checked, and excluded. Open the oil return valve and the piston descends to its original position.

★ Wipe the surface of the test piece clean and check for obvious defects in the appearance. If it can affect the test value, replace the non-destructive test piece.

★ Position the wire frame of the lower plate of the test piece in the middle of the lower plate. According to the size of the test piece, turn the handwheel and the screw to adjust the upper plate to the proper position.

★ Turn on the power of the measurement and control system (the switch is on the back of the measurement and control box), and follow the operation steps to clear the data and modify the clock.

★ Press the start button, close the oil return valve, regulate the oil delivery valve, and perform the loading test smoothly at the required rate until the test piece is crushed and the load is reduced. The oil return valve is then opened, allowing the oil to quickly flow back to the tank.

★ At the end of the test, press the "Print" key on the panel. The printer can print out the test report.

★ During operation, the height of the lower platen must not exceed 4cm (or the marking line on the column) to avoid accidents.

★ It is forbidden to place any part of the human body, such as hands, between the upper and lower pressure plates during operation, and pay attention to the fragmentation of the test piece when it is broken to hurt people.

★ After the test, the broken test block is cleared for the next test. When no longer doing the test, open the oil return valve, close the oil supply valve, and cut off the power.
