Well Pump Head Pressure

In this study it was decided to apply inner liner diameters of about 8 9 cm 3 and.

Well pump head pressure.

A direct driven sprinkler system. If the water level is higher than the pump then the suction head is negative and pump head will increase. Where p pressure psi h head ft. This is because the pump must use energy to bring the water to the level of the pump.

The pressure at the discharge of the pump however will be higher for the heavier solution. When a pump is started up with an open valve there is initially little system head pressure acting in opposition to the pump head capacity curve. Or the pressure that is required for an application if a pressure tank is not used e g. The discharge pressure of the pump should be approximately equivalent to the total dynamic head tdh required by the system tanks pipes elbows valves flanges and fittings.

Whether you re pumping water or a heavy caustic solution the head achieved will be the same. Given the lower system head the intersection of the h q curve with the system head curve is out towards the right end of the h q curve at or near runout. Considering the thermal regime in the study area calculations indicate a pressure loss of about 4 2 bar since a well head pressure whp of about 15 8 103 kpa during the oxidizer injection and of 3 6 bar taking into account the ucg operation at slightly sub hydrostatic pressure in the target coal seam which is expected to be in an acceptable range for the chosen liner diameters and well dimensions. To monitor and control your pump your pump should have a suction pressure gauge and a discharge pressure gauge installed on the pump.

This is because the water entering the pump applies additional pressure at the suction. Total dynamic head tdh.
