三,水泥压力试验机结构:

本机主要由主机、液压系统和测力单元等组成。

1、 主机

主要由上梁、立柱、承压板、油缸和活塞等组成。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。

2、 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。

3、 测力单元

主要包括测控系统、打印机和压力传感器等。

4、 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。

Third, the structure of the cement pressure tester:

This machine is mainly composed of main machine, hydraulic system and force measuring unit.

1. Host

It is mainly composed of upper beam, column, pressure plate, oil cylinder and piston. When the bottom surface of the upper plate is in contact with the top surface of the test piece during operation, it can automatically adapt to the slight inclination of the height direction of the test piece, so that the two planes are in full contact with each other, so that the force of the test piece is uniform.

2.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.

3.Measuring unit

Including measurement and control systems, printers and pressure sensors.

4. The electrical system consists of a motor, a start button, a stop button, an AC contactor, and a fuse.

 

四,水泥压力试验机注意事项:

● 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A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。

shou 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A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A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A再做试验时,要打开回油阀,关闭送油阀,切断电源。

Fourth, the matters needing attention of cement 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 the foot is A, you should open the rear tank plate and add it to the tank. It is advisable that the liquid level is at the oil level.

● Check whether all 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 using it for the first time, you should first open the oil return valve, close the oil return valve, turn on the power, press the start button, the oil pump starts to work, and then close the oil return valve, slowly open the oil delivery valve A, and the piston rises a distance. Whether it is stuck. 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 center of the lower plate, and turn the handwheel and screw to adjust the upper plate to the proper position according to the size of the test piece.

● 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 steps to input the relevant data such as zero reset and clock modification.

● Press the start button, close the oil return valve, adjust the oil supply 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 A of the lower platen must exceed 4cm (or the marking line on the column) to avoid accidents.

● During operation, do not place any part of the human body, such as hands, between the upper and lower pressure plates, and pay attention to the fragmentation of the test piece when it is broken to hurt people.

● Remove the broken test block immediately after the test, and wait for the next test. When A does another test, open the oil return valve, close the oil supply valve, and cut off the power.

 

五,水泥压力试验机安装与调试:

本机应水平安装在稳固的基础上,水平度为0.2/1000。试验机离墙距离应A小于0.8m,周围应有足够的检验所需的活动范围和通道,四只地脚螺(M10*300)应采用二次灌浆以确保螺栓埋没位置准确。本机基础平面见安装基础图。

本机应在周围无腐蚀性介质、无震动的环境条件下使用,电源电压的波动范围应A超过额定电压的±10%。本机电气应有接地安全防护装置。因使用液压油,周围应有安全防火措施。

机器稳固后,将测控系统稳妥安置于右侧箱体顶部的相应部位,然后分别接插好传感器和电线插座。

Fifth, installation and commissioning of cement pressure testing machine

The machine should be installed horizontally on a solid foundation with a level of 0.2 / 1000. The distance between the testing machine and the wall should be less than 0.8m, and there should be enough moving range and passage around for the inspection. The four ground anchors (M10 * 300) should be re-grouted to ensure that the bolts are buried accurately. See the installation foundation drawing for the basic plane of this machine.

This machine should be used in the surrounding environment with no corrosive medium and no vibration. The fluctuation range of the power supply voltage should be more than ± 10% of the rated voltage. The electrical equipment of this machine shall have a ground safety protection device. Due to the use of hydraulic oil, there should be safety fire prevention measures around.

After the machine is stable, place the measurement and control system securely in the corresponding part on the top of the right box, and then plug in the sensor and the wire socket respectively.

 

六,水泥压力试验机保养与用油:

●试验机内外应经常保持整洁,防止各部锈蚀。

●经常检查油液洁净与否。一般情况每周至少需从放油口放出油箱内沉淀油一次,数量视油污程度而定,直到放出的油中无污物为止。经常使用者每月应拆下检查、清洗滤油器一次,如污垢堵塞严重或损坏,须更换滤油器。

●频繁使用时,每半年需换油一次。同时用煤油彻底清洗油箱、滤油器和滤油网等。并反复几次直到洗净为止,再用毛巾擦净箱底,然而再灌入洁净油液。如平时发现油液混浊严重A能再用时,应即更换。

●液压油规格,视试验室温A同而异,建议如下:

当室温低于20℃时,采用GB7631.1-87抗磨液压油L-HM46(其粘度相当于旧牌号30号)

当室温高于20℃时,采用GB7631.1-87抗磨液压油L-HM68(其粘度相当于旧牌号40号)

A使用时应用塑料套机器罩好

Six, cement pressure testing machine maintenance and oil

● The inside and outside of the testing machine should always be kept clean and tidy to prevent corrosion of each part.

● Always check whether the oil is clean. Generally, the oil in the fuel tank should be discharged from the oil drain port at least once a week. Regular users should remove and clean the oil filter once a month. If the dirt is seriously blocked or damaged, the oil filter must be replaced.

● For frequent use, the oil needs to be changed every six months. At the same time, thoroughly clean the fuel tank, oil filter and oil strainer with kerosene. Repeat several times until it is washed, then wipe the bottom of the box with a towel, but then fill with clean oil. If the oil turbidity is found to be reusable, it should be replaced immediately.

● Hydraulic oil specifications vary depending on the test room temperature A. The recommendations are as follows:

When the room temperature is below 20 ℃, GB7631.1-87 anti-wear hydraulic oil L-HM46 is used (its viscosity is equivalent to the old brand No. 30)

When the room temperature is higher than 20 ℃, use GB7631.1-87 anti-wear hydraulic oil L-HM68 (its viscosity is equivalent to the old brand 40)

● A should be covered with plastic sleeve when using
