The pump shaft is a key component in centrifugal and rotary positive displacement pumps, transmitting torque from the prime mover to the pump’s impeller or moving parts. As the core of the pump rotor, it is equipped with impellers, shaft sleeves, bearings, and other components. Its main functions are to transmit power and support the impeller for normal operation.
The oil pump shaft is usually connected to an electric motor or internal combustion engine. These driving sources generate rotational force, which is transmitted through the pump shaft to the internal components of the pump, enabling it to operate efficiently. The pump shaft transfers the rotational motion from the driving source to the impeller or rotor. As the impeller or rotor rotates, it generates suction, drawing oil from the storage area or well into the pump.
Inside the pump, mechanical energy is converted into kinetic energy and pressure energy of the liquid. The rotating impeller or rotor creates centrifugal force or axial thrust in the oil, pushing it at high pressure and speed towards the pump outlet. The rotational motion transmitted by the pump shaft ensures a continuous flow of oil from the pump inlet, through the outlet, and into the required pipelines or storage facilities. The continuous rotation of the pump shaft guarantees the stable transport of oil.
Examples of pump shaft applications include:
- In centrifugal pumps, the pump shaft drives the impeller to rotate, using centrifugal force to push oil from the center of the pump to the periphery, then through the outlet pipeline.
- In plunger pumps, the pump shaft drives the plunger to reciprocate, drawing oil from the intake port and expelling it through the discharge port.
In summary, the oil pump shaft plays a critical role in the extraction, processing, and transportation of oil, ensuring efficient and safe delivery of oil.
