A mechanical seal is used in centrifugal pumps to prevent liquid from damaging the delicate parts of the machine. It is situated on the motor shaft and serves as a check valve .
Centrifugal pumps are widely used in various industries for their efficient and reliable performance in transferring fluids. Understanding the functions of the different parts of a centrifugal pump is essential for proper maintenance and operation. In this article, we will delve into the functions of the key components of a centrifugal pump, including the shaft and shaft sleeve, impeller, casing, suction pipe, and delivery pipe.
It is one of the simple and exciting topics in fluid mechanics.What is the need for a pump? We require a pump to transmit water from a region of low pressure to a region of higher pressure. The centrifugal pump defines as a hydraulic machine that converts mechanical energy into hydraulic energyby means of
Shaft and Shaft Sleeve
The shaft in a centrifugal pump plays a crucial role in transmitting power from the motor to the impeller. It is responsible for rotating the impeller to create the necessary centrifugal force for fluid movement. The shaft sleeve, on the other hand, protects the shaft from wear and corrosion caused by the pumped fluid. It acts as a barrier between the shaft and the fluid, ensuring the longevity and efficiency of the pump.
Impeller
The impeller is the heart of a centrifugal pump, responsible for generating the centrifugal force needed to move the fluid. It consists of curved vanes that spin rapidly when the shaft rotates, creating a low-pressure zone at the center of the impeller. This low pressure draws the fluid into the pump and accelerates it towards the outer edges, where it is discharged through the casing.
Casing
The casing of a centrifugal pump houses the impeller and provides a passage for the fluid to flow through. It is designed to direct the fluid in a specific direction to maximize efficiency. The casing also helps to maintain the structural integrity of the pump and prevents leakage of the pumped fluid. Additionally, the casing plays a role in reducing turbulence and increasing the pump's overall performance.
Suction Pipe
The suction pipe of a centrifugal pump is responsible for drawing the fluid from the source into the pump. It is crucial for maintaining a steady flow of fluid and preventing cavitation, which can damage the impeller and reduce the pump's efficiency. The size and design of the suction pipe must be carefully selected to ensure optimal performance and prevent air from entering the system.

Again the rule of thumb follows that of volumetric efficiency, and losses increase as flow and/or specific speed decrease. . However, when machines operate in series, their combined efficiency is different. Just as the total efficiency of a centrifugal pump is the product of several different internal efficiencies, so is the total efficiency .
