A dismantling view of centrifugal pump shows with what type of items it is made off. During the 17th century, it is one of the peculiar devices that were invented for fluid pumping. As of now they are modified and redesigned with advanced technologies, made capable of handling heavy-duty pumping systems. For household and industrial purpose these machines work to maintain constant flow rates and provide the 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 the 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 energy is supplied to the liquid by the additional sources to make it flow. It is mainly kinetic energy. Electric motor continuously supplies it to the fluid inside the casing by impeller rotation.
Below drawing briefs the fitting of the mechanical part of 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 the important part which makes the pump. Design engineers can modify these parts replacing them more mechanical system. However, an ideal case of manufacturing of a pump is based on these parts like O-ring(412) material of construction, changing the position of the hexagonal head bolt(901), the Volute casing(102) geometric shape based on material handling.
In the dismantling view drawing, upper section shows 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, a mechanical seal is fitted if not packings are provided to prevent the leak from the casing through the edges of rotating shafts. Bearing provides sufficient smooth rotation of the shaft with less friction.
In the lower section of drawing stuffing box is shown where the bearings are supplied with lubrication. The lubricant is filled in its oil compartment to cool the bearing and provide necessary lubrication to the shaft and bearing wheel balls.
Artificial intelligence in assembling centrifugal pump (Genetic engineering algorithm)
To know the perfect optimized sequence for assembling a pump. Genetic algorithms are best options. The complex situation of decision making for engineering a machine or device as per design. And to determine its best possible assemble we need high-level computation. Simulating the centrifugal pump design with a large number of variables and condition could cause the error to find out the optimizing result.
To assemble the centrifugal pump from its component there are uncountable paths, with 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.
