Jet pump working principle

In the surface, the reciprocating pump transfers energy to the fluid increases its pressure, drove through surface piping, production tubing (or annular space) until the jet pump , placed on. The working principle of a jet pump depends on the Bernoulli theory. In a jet pump , water is pushed in a pipe with high pressure. There is a nozzle at the opening of the pipe.

The shape of the nozzle is like a cone.

While the power fluid passes the nozzle, due to the decrease in flow area it is transformed from low velocity, high static pressure flow to a high velocity, low static pressure flow (P S ). After the pump is prime a motive fluid is pumped through a standard centrifugal pump and enters an ejector. This produces an artificially low pressure in the ‘throat’ capable of ‘pumping’ gas. That is, they make use of the momentum of one fluid to move another. Due to the pressure drop of the motive flui it will create a low-pressure zone before the mixing chamber.

Design features and working principle of jet ejectors The term jet ejector describes a device in which a pumping effect is achieved using a motive fluid. A jet ejector requires no mechanical drive and has no moving parts. This basic principle applies to every jet ejector in different models and ranges of application. An eductor- jet pump or jet pump is a type of pump where the energy from one fluid (liquid or gas) is transferred to another fluid via the Venturi effect. As the fluid passes through a tapered jet ,. When a jet is used with a centrifugal pump a portion of the water delivered by the pump is returned to the jet ejector to operate it.

The jet lifts water from the well to a level where the centrifugal pump can finish lifting It by suction. It also allows the produced fluids and gas to be confined by the drill string. The rig mud pumps , using water, are used as a surface power source for operating the jet pump.

Production rates in excess of 10BPD have been achieved. Nozzle profiles selected is conical.

Working principle A standard Flygt N- pump generates the primary liquid flow (see figure). Air is drawn down through the air suction pipe into the ejector. Discover ideas about Jet Pump. A pump - jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines.

Water enters the pump through this inlet. Jet pumps artificial lift system are composed of two principal parts: the. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle.
