    What is the theoretical flow of hydraulic pump

    What is the theoretical flow of hydraulic pump Expand all theoretical flow refers to the volume of oil output by the hydraulic pump in unit time without considering the leakage loss of the hydraulic pump. It is commonly expressed in QT, and the unit is L / min (L / min). The relationship between displacement and theoretical flow is: where n - rotation speed of hydraulic pump (R / min); Q - displacement of hydraulic pump (ml / R) actual flow Q refers to the volume of oil actually output by hydrau...

    Requirements of hydraulic oil for plunger pump

    In the daily working environment, the plunger pump can not avoid inspection and maintenance, which also has certain quality requirements for hydraulic oil. The following are the quality requirements of the plunger pump for the hydraulic oil Quality requirements of plunger pump for pressure oil 1. Proper viscosity and good viscosity temperature performance, so that the hydraulic components can be well lubricated, cooled and sealed under the condition of changing working pressure and temperature. ...

    How many kinds of common hydraulic pumps are there

    How many kinds of common hydraulic pumps are there? Expand the definition of all hydraulic pumps: a machine that can change mechanical energy into hydraulic energy by changing the closed working volume to achieve liquid suction and pressure. Types of commonly used hydraulic pumps: 1. According to whether the flow can be adjusted, it can be divided into variable displacement pump and fixed displacement pump. The output flow can be adjusted according to the needs is called variable pump, and the f... Read More

  • Main principles of selecting hydraulic pump

    Main principles of selecting hydraulic pump

    The primary criterion for selecting a hydraulic pump is the condition demand of the centering system, and on this basis, the output, operating pressure and structural type of the pump are determined. (1) To determine the flow of the extra flow pump of the pump, the highest speed demand of the element shall be implemented satisfactorily. Therefore, the output flow QP of the pump shall be determined according to the maximum flow and the leakage required by the system, that is, QP ≥ kqmax, QP The o... Read More

  • Why is vane pump widely used?

    Why is vane pump widely used?

    When the rotor of vane pump rotates, under the action of centrifugal force and pressure oil, the tip of vane clings to the inner surface of stator. In this way, the working volume formed by the two blades, the rotor and the inner surface of the stator first absorbs oil from small to large and then discharges oil from large to small. When the blades rotate for one circle, the oil absorption and discharge are completed once. 1、 Working principle of single acting vane pump The pump is composed of r... Read More
