Pipes water can be raised to a position above the pump and water. For example, if the pump under three meters at the pond, then the pipes on the pump outlet can be 30 meters. As can be seen repairing the hydraulic motor, piston has a big drawback hydraulic motor repair, it wastes a lot of water. Typically, this type of hydraulic motor pump in 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. 2, displacement and flow (1) per revolution displacement hydraulic pump V, the volume of liquid discharged by sealed volume changes calculated geometry called displacement pump. Displacement hydraulic pump can be adjusted is called a variable pump; pump displacement can not be adjusted is called a metering pump. (2) Theoretical flow theory flow means without regard for the conditions of the hydraulic pump leak flow hydraulic motors for sale, liquid volume per unit time discharged. If the pump displacement is V, its spindle speed is n, then the pump flow rate qt theory is qt = Vn where V is the pump displacement (m3 / r), n is the spindle speed (r / s ) (3) qt pump actual flow conditions in a particular volume of liquid discharged per unit time is called the actual flow rate, which is equal to the theoretical flow qt minus leakage and compression flow ql loss after that q = qt a ql (4) qn nominal flow under normal operating conditions, the test standards (such as at rated pressure and rated speed) must ensure that traffic.
