The company's large-tonnage electric hydraulic jacks, double circuit, hydraulic return thin self-locking hydraulic jack, in large projects, long proven, is easy to operate and control the electric hydraulic jack manual hydraulic jack, product installation hydraulic lock, having packing function, standard pressure relief valve to prevent overload, it can protect the electric jack will not be damaged due to overload, facilitate safe operation. Connection to the device, using high-pressure hose and nipple connection, has the advantage of quick installation and removal, and to overcome the shortcomings of the traditional oil spill quick connectors, with traffic flow, rapid prototyping of advantages. Electric jack is mainly used for hydraulic lifting and removal operations electricity, construction, machinery manufacturing, mining, railway bridges, shipbuilding and other industries and other equipment installed. As we know, the main hydraulic jack is a hydraulic jack, pump stations and pipes (mainly pressure tubing) consisting of hydraulic jacks smooth work process is not smooth, piping installed in the whole process is very important to Jack, today small as we share is to pay attention to the point hydraulic jacks pipeline installation. 1) the oil return pipe hydraulic jacks (pressure tubing) and pumping out into the oil tank should be below the surface of hollow jack, you can prevent the oil splashing bubble mix of people. 2) AIDS valve return line is not allowed and the pump inlet in direct communication, can be used alone to tank, and the main return line of the cooler connected, avoid the oil temperature to rise too fast. 3) has an external leak valves, sequence valves, solenoid valve drain port communicated with the return line to allow back pressure, or should be separate to tank, so as not to affect the normal operation of the valve, which further leads to the hydraulic jack can not working properly. 4) Install a horizontal pipe, there should 3/1000 5/1000 of a slope. 500mm should be fixed a clamp tubing hose clamps. Line too long. Jieyang jack electric jack _ _ Lu Lu of hydraulic force provided by the hydraulic machinery plant in Texas. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu Hydraulic and you hand into the brilliant, for a better future!
