In a hydraulic system with a directional axial piston pump drives a motor, rated working pressure 200bar, pump speed requirements of the motor Maximum speed 540rpm 1800rpm maximum output torque 320N.m reasonable matching namely displacement pump and motor specifications. Rounding value can be, it is not necessarily the same specifications, without regard to efficiency. (Shaft torque = displacement * Pressure / 20π) NOTE: In a hydraulic system with a directional axial piston pump drives a motor, rated working pressure 200bar, pump speed requirements of the motor Maximum speed 540rpm 1800rpm maximum output torque 320N .m reasonable matching namely displacement pump and motor specifications. Rounding value to the hydraulic motor, is not necessarily the same as the specifications of the hydraulic motor repair, without regard to efficiency. (Shaft torque = displacement * Pressure / 20π) KOS hydraulic piston pump is generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps, which are: EKO single piston, KOS, KOV, HSP three kinds of double-piston pump. The pump belongs to positive displacement pumps, especially for high solid content, long distance pipeline viscous material, the advantage is to run very stable and reliable, but noisy hydraulic motor maintenance, delivery pressures up 130Bar, the displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging, dredging, petrochemical installation hydraulic motor, power plants, cement industry and other fields. [Edit this paragraph] Piston - piston principle has been around for decades, its popularity depends on two main reasons: 1. They do not need external energy - the force of water they provide the The energy required. 2, their equipment is extremely simple, with only two moving parts. Repair of hydraulic motors, hydraulic creating crystal factory direct (certification), the hydraulic motor from Jinan Jing Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the crystal creating hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal creating hydraulic better future.
