根据生产需要,我厂把液压千斤顶改装成如图1所示的栓塞式液压油泵。方法很简单,只要将千斤顶内活塞杆拆除,重新配制一油缸端盖。在端盖上拧上管接头,油缸上端的泄油孔用电焊方法点焊,以防漏油。为使加油方便,在外套原加油孔上焊接了一根加油管。加满油并接通油管即可使用。工作原理:拧紧卸荷阀,扳动千斤顶柱塞(柱塞的上下运动是依靠手柄 According to production needs, I plant the hydraulic jack converted into a plug hydraulic pump shown in Figure 1. The method is very simple, just remove the piston rod in the jack and reconfigure a cylinder cover. On the end cap screwed on the pipe joints, the top of the cylinder drain hole welding method of spot welding to prevent oil leakage. In order to facilitate the fuel, the original hole in the coat welded a refueling pipe. Fill the oil and connect the tubing to use. How it works: tighten the unloading valve, pull the jack plunger (plunger up and down movement is to rely on the handle
