Pump Flow Diagram
The directional control valve with built in relief features optional flow control to control the speed of the winch.
Pump flow diagram. The diagram shows a winch powered by a hydraulic motor. The output pressure of the pump is set using a back pressure regulator. Therefore to control the flow of a centrifugal pump simply set the output pressure to the point on the p v diagram that allows the pump to deliver the desired flow rate. Compressor is a mechanical device that takes in a medium and compresses it to a smaller volume.
Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps in which the displacement flow through the pump per rotation of the pump cannot be adjusted or variable displacement pumps which have a more complicated construction that allows the displacement to be adjusted hydraulic pump. Process flow diagram symbols equipment pumps and tanks come in a variety of designs and shapes. Jet pumps are mounted above the well either in the home or in a well house and draw the water up from the well through suction see single drop jet pump system diagram on next page. Two units connected to one flow center figure 6.
A mechanical or electrical drive is typically connected to a pump that is used to compress the medium. The hydraulic pump and motor must be matched to the torque requirements of the winch.
