我们一块介绍分享液压压力试验机的一些功能用途以及操作,首先我们介绍一下其液压系统,油箱内的油经过过滤油网被吸入油泵后,经油泵的输油管送到送油阀内,当送油手轮关闭时,由于油压作用而将活塞推开,油从回油管流回油箱,当送油手轮打开时,则油液经由油管进入工作油缸内,再通过压力油管经过回油阀体流回油箱。
We introduce a block share some hydraulic pressure testing machine function and operation,we first introduce the hydraulic system, the fuel tank through the filter net oil is sucked into the pump, the pump oil pipe to the oil supply valve, when the oil feeding hand wheel is closed, because the oil pressure and the piston pushed away, the oil from the oil return tank,oil feed handwheel when opened, the oil fluid through tubing into the working cylinder, and then through the pressure oil through the oil return valve to tank.
具体的操作步骤,我们也整理了一下,希望对大家有所帮助。
Specific operation, we also finishing it, we hope to help.
1、拧开回油阀,使下压板下降,取出压碎的试样。
1, unscrew the oil return valve, so that the lower platen down, take out the test samplecrushed.
2、记录下来需要的载荷数值,并将描绘笔抬起。
2, record the need to load value, and described the pen up.
3、试样压碎后,关闭送油阀,并停止油泵电动机。
3, the sample after crushing, closes the valve, and stop the oil pump motor.
4、按试验要求加荷速度,缓慢地拧开送油阀进行加荷试验。
4, according to the requirements of experiment loading speed, slowly unscrew the oil supply valve for loading test.
5、开动横梁电动机,使上压板下降到离试样约10mm处,再转动横梁上的手轮,使上压板与试样表面接触。
5, use the beam motor, the upper pressing plate dropped from the sample of about 10mm,and then rotate the handwheel on the cross beam, the upper pressing plate in contact with the sample surface.
6、将主动针及被动针调整到零,关闭送油阀。
6, the active and passive needle needle adjustment to zero, close the oil supply valve.
7、开动油泵,拧开送油阀,使下压板的轮子离开轨道约10mm。
7, start the oil pump, the oil supply valve, so that the plate under the wheels out of orbit of about 10mm.
8、在描绘筒的转筒上卷压好记录纸,此项只是需要时进行。液压压力试验机的操作流程
8, in the depiction of drum drum roll pressure recording paper, this just when needed.Hydraulic pressure testing machine operation process
9、根据试样所需测量范围,在摆杆上挂上或取下相应的摆铊,并把缓冲阀手柄上的刻线对准标线。
9, according to the samples required measuring range, on a swing rod hung or disassembledthe pendulum thallium, and the buffer valve handle on the reticle alignment mark.
10、把下加压板推到试验机内,并对准中心。
10, the lower pressure plate is pushed to the testing machine, and alignment.
11、使总开关接通电源,将试样放在下加压板上。
11, the total switch on the power, the specimen is put in with the plate.
