水压试验机设备

  水压试验机的主要特点:

  (1)水压试验(yan)机(ji)本(ben)体采用封闭框架结构(gou),受(shou)力(li)均(jun)匀,试验(yan)压力(li)大;

  (2)油水(shui)压(ya)控制(zhi)采(cai)用增压(ya)缸连续控制(zhi)保压(ya),可靠高,响应时间快;

  (3)压力传感器自(zi)动检测油水压力,检测精度高,反应灵敏;

  (4)压力测试值(zhi)液(ye)晶数(shu)字显示,直观可(ke)靠;

  (5)保压时间任意设定操作台面(mian)板旋钮(niu)控制,方便简单;

  (6)自动检测压力:实(shi)现显示屏自动显示时间压力曲线、输出(chu)功能(neng);

  (7)试压过程PLC控制(zhi)可升级自(zi)动记录每次(ci)试验结果;

  (8)移动侧液压进给工作(zuo)效率高(gao),试压周期(qi)短;

  (9)试压(ya)过程手动、自动两种控制(有些还增加(jia)了半(ban)自动控制)随意切换方(fang)便故(gu)障的排除(chu)。

  对于端面密(mi)封(feng)条件(jian)(jian)下(xia)的(de)钢(gang)管静水压试验机相对于径向密(mi)封(feng)形(xing)式(shi),端面密(mi)封(feng)形(xing)式(shi)夹(jia)具(ju)不同的(de)钢(gang)管水压时,具(ju)有(you)不用更(geng)换(huan)密(mi)封(feng)圈、生产效率高、需要的(de)夹(jia)具(ju)工装(zhuang)件(jian)(jian)少以及生产成本低等诸(zhu)多(duo)优(you)点,在钢(gang)管直(zhi)径≥610mm的(de)钢(gang)管上得到广泛应用。
