  • Description

产品简介:千斤顶是生产中常用的一种起重工具。QYL型立式油压千斤顶是国家定型新系列产品。它的构造简单、操作方便、体积小,重量轻,便于修理。广泛适用于工厂仓库、桥梁、码头、交通运输建筑工程等部门的起重作业。本产品只能直立使用,其工作环境温度为-20摄氏度+45摄氏度,不宜在酸碱及腐蚀性气体中使用。

工作原理:

油压千斤顶是根据帕斯卡定律的原理工作的。它由油箱,大小不同的两个压力油缸、摇杆和关闭针阀等几个部分组成。工作时,提起小活塞将油吸入小压力油缸,当压下小活塞时将油压进大压力油缸。通过两个阀门的控制,小活塞对油的压强传递给大活塞,将重物顶起来。小活塞不断地往复动作,就可以把重物顶到一定的高度。工作完毕,打开关闭针阀,使大压力油缸和油箱连通。这时,只要在大活塞上稍加压力,大活塞即可下落,油回到油箱中去
