Low speed high torque hydraulic motor can be divided into: radial piston hydraulic motor, crank rod hydraulic motors, hydraulic motors and swing cylinder cycloid hydraulic motors crank link several low speed high torque hydraulic motor application earlier abroad called Star Hair (Staffa) hydraulic motor. Our model is similar JMZ type (domestic) pump agency, its rated pressure 16MPa, the maximum pressure 21MPa, the theoretical displacement up 6.140r / min high vacuum gear pump works: high vacuum pumps rely on the main gear driven gear mutual engagement to pump oil into the suction chamber and the pressure chamber. Since the suction chamber intermeshing teeth gradually disengaged, the sealing working volume increases, the formation of a partial vacuum, and therefore the oil tank under the effect of ambient atmospheric pressure, through the suction pipe into the suction chamber, the groove is filled teeth, and with the gear rotates, the oil pressure oil chamber to the left side. In the pressure side of the oil zone (domestic) pump repair phone, due to gradually enter the meshing teeth here (domestic) pump finishing, sealing the working chamber volume decreasing, the oil will be squeezed out from the pressure oil chamber transported to the pressure line to go. (Domestic) hydraulic repair, hydraulic pumps, hydraulic pressure from 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 continuous improvement to create innovative ideas will lead crystal hydraulic and you hand into the brilliant, for a better future!
