How is pump coupled with motor?

Table of Contents

A pump coupling is the element used to connect the rotating pump shaft to the drive shaft of the motor; enabling the motor to efficiently transmit power to the pump. When a pump is close coupled, a separate coupling is not required as the motor is directly mounted to the pump on a single shaft.

What is the purpose of the coupling between the pump and motor on an oil furnace?

Pump couplings serve an important purpose, the greatest of which is to connect the pump to the motor for the efficient transfer of power. They also help accommodate for misalignment, making it easier to service the pump; and in the case of flexible coupled pumps, help protect the bearings.

What is coupling and different types of coupling?

Gear Couplings Each coupling consists of two hubs with crowned external gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted together. Gear couplings accommodate angular and axial misalignment by the rocking and sliding of the crowned gear teeth against the mating sleeve teeth.

Which type of coupling is used for pumps?

What type of coupling is used in pump?

Elastomeric couplings are the most common coupling used today. They’re found on almost every small to a mid-sized pump installed due to their quick and easy installation and their innate ability to absorb all types of shock, misalignment, and end float.

What are the two types of coupling?

Following are the different types of coupling:

Rigid Coupling.
Sleeve or muff coupling.
Clamp or split-muff or compression coupling, and.
Flange coupling.
Flexible coupling.
Bushed pin-type coupling,
Universal coupling.
Oldham coupling.

What is coupling in centrifugal pump?

The shaft coupling is the connecting element between the electric motor and the pump hydraulic system. Slip-free shaft couplings employed in centrifugal pumps are divided into rigid and flexible shaft couplings. Rigid shaft coupling. Rigid shaft couplings are mainly used to connect perfectly aligned shafts.

What is a flex coupling?

A flexible coupling exists to transmit power (torque) from one shaft to another; to compensate for minor amounts of misalignment; and, in certain cases, to provide protective functions such as vibration dampening or acting as a “fuse” in the case of torque overloads.

What is mechanical coupling?

Couplings are mechanical components used to connect two in-line shafts to enable one shaft to drive another at the same speed. A coupling can be rigid or flexible, allowing various amount of angular, radial, and axial misalignment between the two shafts.

What is meant by direct coupling?

In electronics, direct coupling or DC coupling (also called conductive coupling and galvanic coupling) is the transfer of electrical energy by means of physical contact via a conductive medium, in contrast to inductive coupling and capacitive coupling.

What is the application of direct coupling?

Application. Direct-coupled amplifiers are used in voltage regulators, servo drives and other instrumentation amplifiers. It also forms a building block for differential amplifiers and operational amplifiers.

What is direct coupling pump?

The finished setup resembles an integral pump-motor. If there’s a flexible coupling between the shaft and pump, it is called a direct coupled drive. This is one of the most common ways to drive a pump. It has most of the benefits of a direct drive, but eliminates the need for precise shaft alignment.

What kind of coupling do you use for stepper motors?

With a bellows between two hubs, these couplings handle all types of misalignment and are good for precision stepper and encoder motion-control applications. Connect shafts and ball screws to high-speed servomotors and stepper motors— these shaft couplings handle four times more speed than standard servomotor couplings.

What type of coupling is best for servomotors?

Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications. With a bellows between two hubs, these couplings handle all types of misalignment and are good for precision stepper and encoder motion-control applications.

What is the difference between an indirect drive and a coupling drive?

Coupling backlash or “windup” is generally not an issue. Indirect drives use gears, pulleys, or chains to offset the motor shaft from the shaft turning the pump, providing the obvious advantage of being able to adjust the speed or rpm level of the pump shaft. Indirect drives can be configured to yield almost any motor/pump speed ratio.

What are double loop couplings used for?

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment. Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications.
