Pumps are used for moving fluids, such as liquids, slurries, or gases. Three major groups of this are the displacement, direct lift, and gravity pumps. Positive displacement transfers fluid by trapping a fixed amount of it then displacing that amount into the discharge pipe.
Gravity pump is usually referred as a hydraulic ram. This is used by raising the water from the underground to a higher location in lower elevations. Multiphase pumping technologies types and features include buffer tanks, twin screw pumps, helicoaxial, progressive cavity, and electric submersibles. Multiphase production advantages include lesser cost of the equipment, increase in the rate of production, and simpler installation.
A helicoaxial is also called as centrifugal. Centrifugal is used by transporting fluids through converting rotational kinetic energy into hydrodynamic energy. The rotational energy comes from the electric motor, and the fluid will then enter the impeller which is near the rotating axis, and the impeller is going to accelerate it, flowing outwards.
A twin screw is consists of two intermeshing screws that force the movement of fluid that is being pumped. This is often used in pumping conditions that contain a high gas volume or fluctuating inlet conditions. To seal the two shafts, it needs four mechanical seals.
A progressive cavity is one kind of positive displacement. The progress of small, discrete cavity, and fixed shape sequence is being used while turning the rotor. This can act also as motor or mud motor if the fluid is pumped in the interior. An application to this is doing a well drilling.
Electric submersibles contain hermetically sealed motor that is close coupled to its pump. The assembly is being submerged to the fluid which is being pumped. The advantage of this is the prevention of cavities, that is a problem in the difference of the fluid surface and of the pump. Submersibles pump liquids towards the surface. Jets pulls liquids out from the surface, so it can be concluded that submersibles are more efficient compared to jets.
Buffer tanks Cobourg ON are installed upstream of suction nozzle in case of a slug flow. This will break the energy of the liquid slug, will smoothen any fluctuations of incoming flows, and will act as a sand trap. Pumps are usually rated by horsepower, flow rate, outlet pressure of head, and inlet suction of head. Simplification of head is done as the number of feet the pump can raise or lower a column of water in atmospheric pressure.
Stainless steel and other materials such as cast iron are mostly used for pump production. Materials depend on how it is going to be used. For pharma application of water industries, they use stainless steel instead of cast iron because it gives better outcome due to its high temperature.
So by the name itself, multiphase have many variations of services and conditions like changing composition of liquid processes, temperature variations, operating high and low pressures, and exposure to abrasive or erosive media. So the challenge for this is to look for appropriate arrangement of mechanical seal and support system to ensure effectiveness and also to ensure quality as well.
