With What Parts a Centrifugal Pump Is Made Off

A dismantling view of centrifugal pump shows with what type of items it is made off. During 17th century it is one of the peculiar devices that were invented for fluid pumping. As on now they are modified and redesigned with advance technologies, made capable of handling heavy duty pumping systems. For house hold and industrial purpose these machines work to maintain constant flow rates and provide driving force for fluid to flow between unit operations. It is simple in structure, assembled with mechanical parts which convert the energy forms of the fluid. It is driven by a motor connected to its shaft.

A design engineer with mechanical and chemical background would include his skills in upgrading centrifugal pump so that they can work with less maintenance and give high performance, they are redesigning it structure with efficient casing, impellers and bearings as we know that the liquid is added with energy which makes it to flow and it is mainly kinetic energy continuously supplied to fluid inside the casing by impeller rotation.

Below drawing briefs the fitting of mechanical part inside an ideal centrifugal pump

Bearing bracket(330), discharge cover(163), cooling cover(165), support foot(183), Shaft(210), impeller(230),  bearing cover(360), flat gasket(400), gasket(411), oil seal(421), gland cover(452), lantern ring(458), packing(461), wearing ring(502), splash ring(507), shaft protection sleeve(524), washer(550), washer for impeller(554), vent plug(913),deep groove ball bearing(321), hexagonal nut(920), key(940), these are important part which make a pump. Design engineers can modify these parts replacing them more mechanical system but an ideal case of manufacturing of a pump is based on these parts like O-ring(412) material of construction, changing the position of  hexagonal head bolt(901), Volute casing(102) geometric shape based on material handling.

Centrifugal pump parts details for design and maintenance

Centrifugal pump parts for assembling sequence


In the dismantling view drawing, upper section show the series of parts present from a casing to bearing cover, the casing is fitted with lock-nut to the impeller and the corresponding gasket rings to the casing, a shaft runs from the center of impeller is locked with lock-nut (906) which holds and give support to rotating and stationary part. At the end of the discharge cover mechanical seal is fitted if not packings are provide to prevent leak from casing through the edges of rotating shafts.  Bearing provide sufficient smooth rotation of shaft with less friction.

In lower section of drawing stuffing box is shown where the bearings are supplied with lubrication. Lubricant is filled in its oil compartment to cool the bearing and provide necessary lubrication to shaft and bearing wheel balls.

Artificial intelligence in assembling centrifugal pump (Genetic engineering algorithm)

To know perfect optimized sequence for assembling a pump, genetic algorithms are best options. The complex situation of decision making in engineering a machine or device as per design and determine its best possible assemble need high-level computation. Simulating the centrifugal pump design with large number of variables and condition could cause error to find out the optimizing result.

To assemble the centrifugal pump from its component there are uncountable paths, by the help of its geometric sketch feasible assembly sequence is determined. Genetic algorithm evolves by operators and the results can be assessed by space state search algorithm to obtain optimized assembly procedure.
