Led by oil pan piston reciprocating plunger is a small cylinder, reciprocating motion to do priming pump oil is to use a plunger sliding piston and the piston sleeve changing the volume to achieve the suction and discharge oil, ending Two-way valve between the plug and the sleeve by viscosity and oil to seal the gap. Piston axial piston pumps and radial piston pumps. Piston axial piston pumps and radial piston pumps. KOS hydraulic piston pump is generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps hydraulic motors, which are: EKO single piston pump, KOS, KOV, HSP three Species double piston pump. The pump belongs to positive displacement pumps, especially for high solid content, long-distance pipeline viscous material conveying hydraulic motor for sale, its advantages are running very stable and reliable, but noisy, delivery pressures up 130Bar, the displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment Liyuan Hydraulic motors, solid waste management, mining and metallurgy, dredging, dredging repair hydraulic motor, petrochemicals, 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.
