Seoca VHS motor are vertical hollow-shaft induction motor. design for driving vertical deep-well turbine pumps. The motor are reliable and design for non-reverse, adopting. weather-protected type 1.
What is a hollow shaft motor?
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.
How do hollow shaft motors 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 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 a steady bushing?
Steady Bushing Installation and Maintenance
This steady bushing is provided to stabilize the pump head-shaft and center it in the bore of the motor shaft at the lower end of the motor. … If motor is received with slinger on bottom end if shaft, remove slinger before lowering motor onto pump shaft.
Why hollow shaft is superior to solid shaft?
Hollow shafts have a more polar moment of inertia, which enables them to transmit more torque than solid shafts. Hollow shafts do not transfer more power but the power to weight ratio of hollow shafts is more as compared to the solid shaft.
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”.
