Pipes water can be raised to a position above the pump and water. Such as a hydraulic motor mounting, 3 m hydraulic motor if the pump in the pond, then the outlet pipes on the pump can be 30 meters. As can be seen repairing the hydraulic motor, piston has a big drawback, it wastes a lot of water. Usually hydraulic motors overhaul, in this type of pump water consumption, in fact, only about 10% of the flow along the pipes up. When the rest of the water accumulated momentum out of the water pump. Piston and no magic. We can use an alternative design approach to achieve the same function: 1, the water flow down from the pond to drive a waterwheel. 2, waterwheel connected to a common shaft drive pumps (or reciprocating pumps, centrifugal pumps, etc.). 3 by this pump to pump water on the high places. First, the parts constituting the sealed volume of the cylindrical piston and cylinder bore, easy to process, can be obtained with high accuracy, good sealing performance, high-pressure work is still high volumetric efficiency; second, just change the column Cypriot working stroke can change the flow, easy to implement variable; third, piston main parts are under pressure stress, the material strength properties can be fully utilized. Due to the high pressure piston pump, compact structure, high efficiency, easy flow regulation, so the need for high pressure, high flow, high-power systems need to adjust the flow rate of the occasion and, as the goal planer, broaching machine, hydraulic machines, construction machinery, mining metallurgical machinery, widely used on the ship. Piston arrangement and the direction of movement of the plunger can be divided into radial and axial piston pump piston into two categories, according to the assignment device type can be divided with a gap-type seal with flow deputy piston and valve piston pump with flow control devices into two categories, according to whether the variable displacement piston pumps are divided into quantitative and variable piston pump.
