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 pump, 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, delivery pressures up 130Bar, displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste disposal Liyuan Hydraulic motors, mining and metallurgy, dredging, dredging, petrochemical hydraulic motors, 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, which means an extremely simple hydraulic motor refinement, only two moving parts. Second, the main performance parameters of the hydraulic pump 1, the pressure (1) working pressure of the hydraulic pump output pressure when the actual work is called work pressure. Working pressure depends on the size of the external load pressure and the discharge pipe of the hydraulic motor installed loss, regardless of the flow rate of the hydraulic pump. (2) Rated pressure pump under normal operating conditions, the maximum pressure according to the test standards for continuous operation called hydraulic pump rated pressure. (3) The maximum allowable pressure in excess of the rated pressure conditions, according to the test standards, to allow the pump to run short of the maximum pressure plant, known as the maximum allowable pressure of the hydraulic pump motor repair, crystal creating hydraulic price (Online) hydraulic motor is provided by Jinan Jing Chong Hydraulic Machinery Co., Jinan Jing Chong Hydraulic Machinery Co., Ltd.
