混凝土压力试验机结构简介：

试验机主要有机体、液压操纵箱、测力仪表等三部分组成。

★主机

主要由上梁、立柱、调节丝杠及手轮、承压板、油缸和活塞等组成。丝杠末端与上压板间装有活动球座，操作时当上压板底面与试件顶面接触后，能自动适应试件高度方向的细微倾斜度，使两平面互相接触全面，从而使度件受力均匀。根据试件大小，可转动手轮和丝杠，以适当调节试验空间。

下压板顶面上刻有定位线框，便于将试件放置在中间位置。

★液压系统

由液压泵、送油阀、回油阀、油箱、滤油器及油管等组成。

液压泵为轴向五柱塞超高压泵，由电动机直联驱动，送油阀上设有安全阀，过载是可溢流，起安全作用。操纵送油阀手轮，可调节油缸进油量，以达所需加荷速率。打开回油阀，可使油缸内和油泵来的油全部流回油箱。

★测力单元

主要包括测控系统、打印机和压力传感器等。(详见所附《RFP-03智能测力仪使用说明书》

★ 电气系统由电动机、启动按钮、停止按钮、交流接触器、熔断器等组成。

Introduction to the structure of concrete pressure testing machine

The testing machine is mainly composed of three parts: organism, hydraulic control box and force measuring instrument.

★ Host

It is mainly composed of upper beam, column, adjusting screw and hand wheel, pressure bearing plate, oil cylinder and piston. There is a movable ball seat between the end of the screw and the upper pressure plate. When the bottom surface of the upper pressure plate is in contact with the top surface of the test piece during operation, it can automatically adapt to the slight inclination in the height direction of the test piece, so that the two planes are in full contact with each other. Even by force. According to the size of the test piece, the hand wheel and the screw can be turned to adjust the test space appropriately.

A positioning wire frame is engraved on the top surface of the lower platen, which is convenient for placing the test piece in the middle position.

★ Hydraulic system

It consists of hydraulic pump, oil delivery valve, oil return valve, oil tank, oil filter and oil pipe.

The hydraulic pump is an axial five-plunger ultra-high-pressure pump, which is directly driven by an electric motor. A safety valve is provided on the oil delivery valve. The overload can overflow and play a safety role. By manipulating the handwheel of the oil delivery valve, the amount of oil in the cylinder can be adjusted to achieve the required loading rate. Opening the oil return valve allows all the oil in the cylinder and the oil pump to flow back to the oil tank.

★ Measuring unit

Including measurement and control systems, printers and pressure sensors. (See the attached "RFP-03 Intelligent Force Gauge Instruction Manual" for details

★ Electrical system consists of motor, start button, stop button, AC contactor, fuse, etc.

混凝土压力试验机注意事项：

★使用时电源电压必须准确无误；

★传感器与主机连接的电缆不得有中间接头，如遇破损需更换电缆，并且接线准确无误；

★使用时必须按说明书规定程序操作。

★操作中严禁下压力板（7）超过活塞规定行程。

★在经过长时间工作后密封圈可能会失效而导致油缸严重渗油，此时应遵循以下方法更换密封圈。

（1）移出下压力板及防尘罩；

（2）用2只M12吊环螺钉吊出活塞后拆出油缸内壁密封圈、环；

（3）装换上新的密封圈、环，并小心放入活塞，盖上承压板，在不使用时始终保持其外表光滑、洁净，不得碰伤，刮毛和堆积杂质。

★压力试验机外壳必须安全接地，试验机机架后侧有接地螺钉。

★标定由计量部门进行，用户不得随意操作。

★压力试验机不能与一个大功率电器设备共用一个电源插座。

★压力试验机应置于干净处，防止灰尘侵入，并在温度为10~35℃，湿度≤80％的工作环境中使用。

★试验结束，传感器应处于脱离载荷状态， 以保护传感器。 试验中执行打印时，若是打印纸用完，换上新的打印纸，按开关SEL键，再按LF键，打印机会自动进纸。

★请不要私自拆卸仪器。

Note for concrete pressure testing machine:

★ The power supply voltage must be accurate when used;

★ The cable connecting the sensor to the host must not have an intermediate connector. If the cable is damaged, replace the cable and the wiring is accurate;

★ Must be operated in accordance with the procedures specified in the instructions.

★ It is strictly forbidden to lower the pressure plate (7) beyond the specified stroke of the piston during operation.

★ After a long period of work, the sealing ring may fail and cause serious oil leakage in the cylinder. At this time, the following methods should be used to replace the sealing ring.

(1) Remove the lower pressure plate and dust cover;

(2) Remove the seal ring and ring on the inner wall of the cylinder after lifting the piston with two M12 eye bolts

(3) Install new sealing rings and rings, and put them into the piston carefully, cover the pressure bearing plate, and keep their appearance smooth and clean when not in use, and do not bump, scrape or deposit impurities.

★ The shell of the pressure testing machine must be safely grounded. There are grounding screws on the back of the testing machine frame.

★ The calibration is performed by the metrology department, and users are not allowed to operate at will.

★ The pressure tester cannot share a power socket with a high-power electrical equipment.

★ The pressure testing machine should be placed in a clean place to prevent dust from invading and used in a working environment where the temperature is 10 ~ 35 ° C and the humidity is ≤80%.

★ After the test, the sensor should be out of load to protect the sensor. When printing is performed during the test, if the printing paper runs out, replace it with new printing paper, press the switch SEL key, and then press the LF key, the printer will automatically feed the paper.

★ Please do not disassemble the instrument without permission.
