High-quality multi-stage cylinder adopts special sealing material and structure to ensure reliable sealing performance: 1) Working temperature range: -45 ℃ ~ + 110 ℃; 2) Sealing material has good rebound during the entire working cycle of the cylinder Characteristics and good sealing performance; 3) Good wear resistance, so long service life. Adopt European standard cylinder material and processing technology to ensure the cylinder strength, stiffness and size matching accuracy, improve the stability and reliability of the cylinder, and thus extend the service life of the cylinder. Technical characteristics 01. An 02. The oil cylinder can bear higher pressure, rated working pressure is not less than 21Mpa 03. The external surface of the cylinder is chrome-plated with good wear resistance and corrosion resistance

ZM-80EZ4 inclined shaft plunger variable displacement plug-in motor can adjust the displacement steplessly within the given range of vgmin and vgmax, high operating pressure, high power density, and has good low speed characteristics and initial characteristics. Variable plug-in motor, comprehensive control method, can meet various application needs. Can be equipped with brake release valve, flushing valve and supplementary valve. The flushing supply valve is used to prevent overheating of the closed circuit and ensure the minimum supply pressure of the system. Technical characteristics Displacement plug-in motor Variable plug-in motor Pneumatic blade motor Variable displacement motor with oblique shaft and axial conical plunger plug It is easy to install and only needs to be inserted into the reducer (no need to consider the installation tolerance) The mounting flange of the motor is designed in the middle of the housing (space-saving structure) The displacement is adjustable between vgmax and vgmin Output speed depends on pump flow and motor displacement The torque increases as the pressure difference and the displacement between the high-pressure side and the low-pressure side increase Application field Widely used in coal mine machinery, underground machinery, road machinery, concrete machinery and other fields.
