What is a hollow shaft motor?

Hollow shaft motors allow the pump head shaft to extend through the motor shaft and connect to an integrally-mounted drive coupling. The advantage goes to hollow shaft motors: – Ease of impeller adjustment. Access at the top of the motor.

How does a hollow shaft motor work?

In hollow shaft pump motors, the pump head-shaft extends through the motor shaft and is joined at the motor’s crest. An adjusting nut is located on the peak of the head-shaft which streamlines the regulation of the pump impeller strength.

What is a vertical hollow shaft motors?

Vertical Hollow Shaft motors are designed for use on turbine, mix flow and propeller pumps. They feature a P-Base style mount where the line shaft goes up through the motor and out the top where it is secured.

Is hollow or solid shaft stronger?

For equal mass A Hollow shaft is stronger than Solid shaft. It is due to the Shear Stress distribution. … Hence Hollow shaft having more diameter can allot more stress into the outer fiber where the force is actually maximum. While the solid shaft is very smaller in diameter for the same mass.

What is VHS motor?

VHS motors are specially designed to drive vertical turbine pumps and the motors are well suited for the application due to the ease of installation and maintenance, permanent shaft alignment, well protected construction, high thrust capability and compact & rugged design. SPECIFICATIONS.

What is AP base motor?

The Vertical P-Base platform is a totally enclosed fan-cooled (TEFC) motor, available in a broad power range. … A non-reversing ratchet used to control motor backspin upon de-energization can protect the entire pumping system.

What is vertical centrifugal pump?

Vertical centrifugal pumps are also referred to as cantilever pumps. They utilize a unique shaft and bearing support configuration that allows the volute to hang in the sump while the bearings are outside the sump. This style of pump uses no stuffing box to seal the shaft but instead utilizes a “throttle bushing”.

Can a horizontal mount motor be used vertically?

While normally mounted horizontally, horizontal motors are sometimes mounted vertically for use with small pumps, gearboxes and other equipment.

Why is a hollow pipe stronger?

The stiffness of the hollow pipe is more than the solid shaft with the SAME WEIGHT. Hollow pipes have a more polar moment of inertia, thus they can transmit more torque compared to solid shafts. Thus, hollow steel pipes are stronger than solid shafts having IDENTICAL WEIGHT.

Why are hollow cylinders stronger than solid cylinders?

The hollow shafts can withstand the same stress as that of solid shafts. … Strength to weight ratio is better for ahollow pipe than a solid rod. This means a hollow cylinder is stronger than a rod of equal mass and the same material. Ahollow cylinder with a bigger inside diameter is better.
