  • 液压扳手的使用方法?
  • 本站编辑:杭州雷恩液压设备制造有限公司发布日期:2022-03-11 11:13 浏览次数:
在石油化工行业的螺栓紧固安装施工过程中,工作环境都比较恶劣;螺栓数量多,使用量大;力矩值要求比较大,扳手长期处于超负荷工作状态。因此,如何正确使用液压扳手,延长液压扳手的使用寿命,安全高效施工非常重要。
一、工作之前检查,检查液压扳手上的螺钉是否松动,转动扳手观察其功能是否良好。检查液压泵油箱是否充满液压油,油管是否裂痕,快速接头是否连接到位,锁紧环是否安装。
二、将扳手置于空地上。启动液压泵,检查油泵运转是否正常。按住线控开关,扳手方轴或棘轮开始转动,扳手到位停止转动,压力表由“0”急速上升至调定压力;松开按钮,扳手自动回程,反复几次,使扳手空转几次,观察扳手转向,以确定锁紧和松拆运行方向,无异常时,将方轴或者棘轮放置套筒上。
三、压力调整,一手将线控开关上按钮按下,此时方轴或棘轮转动,扳手到位停止转动,压力表由“0”急速上升,另一只手调整油泵调压阀,调节压力表中指针所需压力。
将泵站压力调到最高,确认扳手转向为拆松方向,将扳手放在套筒上,找好反作用支点,靠稳,反复执行动作,直至将螺母拆下。确定好锁紧方向,根据力矩值调整好泵的输出压力,将方轴或棘轮安装上套筒,按照试运转时的操作方式,进行操作,直至螺母不再转动。
In the process of bolt fastening installation and construction in petrochemical industry, the working environment is relatively poor; Large number of bolts and large amount of use; The torque value is required to be large, and the wrench is overloaded for a long time. Therefore, how to correctly use the hydraulic wrench, prolong the service life of the hydraulic wrench, safe and efficient construction is very important.
1、 Before work, check whether the screw on the hydraulic wrench is loose, and turn the wrench to observe whether its function is good. Check whether the oil tank of the hydraulic pump is full of hydraulic oil, whether the oil pipe is cracked, whether the quick connector is connected in place and whether the locking ring is installed.
2、 Place the wrench in the open space. Start the hydraulic pump and check whether the oil pump operates normally. Press and hold the wire control switch, the square shaft or ratchet of the wrench starts to rotate, the wrench stops rotating when it is in place, and the pressure gauge rises rapidly from "0" to the set pressure; Loosen the button and the wrench will automatically return. Repeat several times to make the wrench idle for several times. Observe the rotation of the wrench to determine the operation direction of locking and loosening. If there is no abnormality, place the square shaft or ratchet on the sleeve.
3、 For pressure adjustment, press the button on the wire control switch with one hand. At this time, the square shaft or ratchet rotates, the wrench stops rotating in place, the pressure gauge rises rapidly from "0", and the pressure regulating valve of the oil pump is adjusted with the other hand to adjust the pressure required by the pointer in the pressure gauge.
Adjust the pressure of the pump station to the maximum, confirm that the wrench turns to the loosening direction, put the wrench on the sleeve, find the reaction fulcrum, stay stable, and repeat the action until the nut is removed. Determine the locking direction, adjust the output pressure of the pump according to the torque value, install the square shaft or ratchet on the sleeve, and operate according to the operation mode during the test run until the nut no longer rotates.
