四、操作规程：

★使用前应检查油箱内的油液是否充足，可观察右侧面的油标，如不足，则应打开后箱板向油箱内加油至液面在油标处为合适。

★检查各油管接头和紧固件是否松动，检查电气接地措施是否有效。

★检查压力传感器、测控系统过载输出及电源的接插是否有效。

★A使用时，按下启动按钮，接通电源油泵开始工作，开启电脑，使活塞上升一段距离，观察有无卡住等异常现象。如有，则应卸荷停机检查，并排除之；如无异常现象，则按下停止按钮，活塞停止上升。

★根据不同试验，选用抗折或抗压夹具，然后固定并清除周围异物。试验时将试件表面擦拭干净，检查外观有无明显缺损，如有能影响试验数值者，须更换无损试件。

★检测开始前，接通测控系统电源，按操作步骤进行操作，必要时进行清零。

★抗折时将试件平放在两下抗折板上。当试件开始加载时应按所需加荷速率使活塞平稳上升，及至试件折断破碎，负荷下降，工作油缸内的油迅速流回油箱，而活塞则靠其上的重量下降到A低点或需要位置。如需连接试验，则不必将油缸内的油全部放光，使活塞下降太低，只要能容纳下一次试件顺利安装即可。

Fourth, the operating rules of the cement mortar bending test machine

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

★ Check whether the tubing joints and fasteners are loose and whether the electrical grounding measures are effective.

★ Check whether the pressure sensor, the overload control output of the measurement and control system, and the power supply are valid.

★ When A is used, press the start button, turn on the power and start the oil pump, turn on the computer, make the piston rise for a distance, and observe whether it is stuck or not. If there is, check the load and stop it and eliminate it; if there is no abnormal phenomenon, press the stop button to stop the piston from rising.

★ According to different tests, choose flexure or compression fixture, then fix and remove surrounding foreign objects. During the test, the surface of the test piece is wiped clean, and the appearance is checked for obvious defects. If it can affect the test value, the non-destructive test piece must be replaced.

★ Before the test starts, turn on the power of the measurement and control system, follow the operation steps, and clear it if necessary.

★ When bending resistance, place the test piece on the bending resistance plate twice. When the test piece starts to load, the piston should rise smoothly at the required loading rate, and until the test piece breaks and breaks, the load decreases, and the oil in the working cylinder quickly flows back to the fuel tank, and the weight of the piston drops to the low point of A. Or need a location. If the connection test is needed, it is not necessary to light all the oil in the oil cylinder, and the piston is lowered too low, as long as it can accommodate the next test piece to be installed smoothly.
