First, the parts constituting the sealed volume of the cylindrical piston and cylinder bore, easy to process, can be obtained with high accuracy, good sealing performance, high-pressure work is still high volumetric efficiency; second, just change the column Cypriot working stroke can change the flow, easy to implement variable; third, piston main parts are under pressure stress, the material strength properties can be fully utilized. Due to high pressure hydraulic piston motor mounting, compact, high efficiency, easy flow regulation, it is in need high pressure, high flow, high-power systems need to adjust the flow rate of the occasion and, as the goal planer, broaching machine, hydraulic machines, engineering machinery, mining and metallurgy machinery, widely used on the ship. Piston arrangement and the direction of movement of the plunger can be divided into radial and axial piston pump piston into two categories, according to the assignment device type can be divided with a gap-type seal with flow deputy piston and valve piston pump with flow control devices into two categories, according to whether the variable displacement piston pumps are divided into quantitative and variable piston pump. It relies on a few of the plunger piston in the cylinder reciprocating slide during the hydraulic motor, to complete the suction - discharge process oil. When the drain, the plunger moves forward, this action driven by the swash plate. When the oil absorption, the rearward movement of the plunger, this action is to return the disc to complete. A spring rear cylinder refinement of hydraulic motors, springs push a ball-type sleeve, the sleeve push return plate. There are 7 or 9 hole repairs hydraulic piston motor, pressed the plunger on the return plate slipper. In the semi-circle rotation of the suction, return plate inclined rotating shoe pushed to the back, the plunger suction action can be done. Sales of hydraulic motor, hydraulic motor, hydraulic preferred by the Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) strong, credible, in Jinan, Shandong mining machinery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead crystal create hydraulic and you hand into the brilliant, for a better future!
