Pump Flow Diagram. 252 shows the ideal indicator diagram. The height of the centre of the pump above the sump water level must not exceed a limit to avoid separation at the inlet of the pump.
It enters inside the rotating impeller vane through the eye. Test for sufficient pump flow the test for sufficient pump flow is conducted in. Must flow continuously whenever the pump is running it must have some where to go if not being used by the actuators.
This is a diagram showing the pressure head in the cylinder during the suction and delivery strokes of the pump under ideal conditions.
If rotating equipment is downstream of the hot tap then a hot tap is not approved because the shavings and cut pieces could enter and damage the machinery eg a pump or compressor. The impeller of a typical axial flow pump and the flow through a radial flow pump are shown in figure 7. Process flow diagrams are widely used by engineers in chemical and process engineering they allows to indicate the general flow of plant process streams and equipment helps to design the petroleum refineries petrochemical and chemical plants natural gas processing plants and many other industrial facilities. A simple hydraulic pump diagram is shown in the figure below.
