Design elements - Hydraulic pumps and motors

The vector stencils library "Hydraulic pumps and motors" contains 74 symbols of hydraulic pump vector stencils, hydraulic motor symbols for engineering drawings of fluid power and hydraulic control systems.
"Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic.
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. Wikipedia]
"A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder.
Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump because it performs the opposite function - much as the conceptual DC electric motor is interchangeable with a DC electrical generator. However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for the working pressure at both sides of the motor.
Hydraulic pumps, motors, and cylinders can be combined into hydraulic drive systems. One or more hydraulic pumps, coupled to one or more hydraulic motors, constitutes a hydraulic transmission." [Hydraulic motor. Wikipedia]
The shapes example "Design elements - Hydraulic pumps and motors" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mechanical Engineering solution from the Engineering area of ConceptDraw Solution Park.

The vector stencils library "Fluid power equipment" contains 113 symbols of hydraulic and pneumatic equipment including pumps, motors, air compressors, cylinders, meters, gauges, and actuators. Use it to design fluid power and hydraulic control systems.
"Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine."

A simple hydraulic schematic showing apparatus for testing the strength of a hydraulic hose splice.
Water enters through normally closed solenoid valve (1) and passes through intake flow meter (2) to high pressure pump (4). Intake water pressure is monitored by pressure gauge (3). The hose to be tested connects between pump (4) and normally open solenoid activated drain valve (7). To test the hose, pump drive motor (5) is turned on, the solenoid of drain valve (7) is activated, closing the valve, and the pump is run to pressurize the hose. Test pressure is monitored by gauge (6). When the test is complete or the hose fails, the solenoid of drain valve (7) is deactivated, opening valve and discharging water, depressurizing the system. All components are operated electrically by a remote control circuit so that the operator may perform the test from a protected location, monitoring it with a camera and video monitor.
