function of coupling in centrifugal pump|oil and gas pump coupling : convenience store Jun 9, 2020 · The coupling of centrifugal pump is used to connect the shafts in different mechanisms, mainly through rotation, to transfer the rotating power of the motor to the mechanical parts of the feed pump, so as to achieve the … Most centrifugal pumps should not be used at a flow rate less than 50% of the B.E.P. (best efficiency point) flow rate without a recirculation line. . This is known to happen when two pumps are in parallel, when the second pump is started it may fail to get to the operating point or hunt between two points that are at equal head. Thankfully .

CALCULATE THE PRESSURE HEAD ANYWHERE ON THE DISCHARGE SIDE OF THE PUMP Equation [4] is the result of an energy balance between points 1 and 2. The same process of making an energy balance can be applied between any two points for example points 1 and X (see Figure 3). We can do an energy balance between points 1
Pump couplings play a crucial role in the operation of centrifugal pumps, serving as the link between the motor or engine (driver) and the pump itself. These mechanical devices are designed to transmit power efficiently while accommodating any misalignments between the driver and the pump. In addition to power transmission, pump couplings also help to reduce the impact of shock loads and vibrations, thereby extending the lifespan of the pump system.
A pump coupling is a mechanical device used to connect two shafts, typically one from the pump’s impeller and the other from the motor or engine. Its primary function is to transmit power while accommodating misalignment, reducing
What is a Pump Coupling?
A pump coupling is a mechanical device that connects the shaft of the motor or engine to the shaft of the pump. It consists of two flanges, one attached to the motor shaft and the other to the pump shaft, which are then connected by a flexible element. This flexible element allows for some degree of misalignment between the two shafts, which can occur due to factors such as thermal expansion, foundation settlement, or manufacturing tolerances.
Oil and Gas Pump Coupling
In the oil and gas industry, centrifugal pumps are commonly used for various applications such as crude oil transfer, water injection, and gas processing. Pump couplings in these applications must be able to withstand high temperatures, corrosive environments, and heavy loads. Couplings used in oil and gas pump systems are often made of high-strength materials such as stainless steel or alloy steel to ensure reliability and durability in harsh operating conditions.
Pump Flange Coupling
One of the most common types of pump couplings is the flange coupling, which consists of two flanges that are bolted together to connect the motor and pump shafts. Flange couplings are simple in design, easy to install, and provide a high level of torque transmission. They are suitable for applications where precise alignment between the driver and the pump is critical, as any misalignment can lead to increased wear and premature failure of the coupling.
Sleeve Coupling Pump
The coupling of centrifugal pump is used to connect the shafts in different mechanisms, mainly through rotation, to transfer the rotating power of the motor to the mechanical parts of the feed pump, so as to achieve the …
the pump less the vapour pressure converted to fluid column height of the liquid. Pump input or brake horsepower (BHP) is the actual horsepower delivered to the pump shaft. Pump output or water horsepower (WHP) is the liquid horsepower delivered by the pump. Pump Efficiency is the ratio of BHP and WHP.
