Abstract
A vertical centrifugal pump belongs to the design and manufacturing technique field for the vertical centrifugal pump, and consists of a pump body and a electric motor. A seal plug is arranged on a balance hole of the blade wheel. The water inlet of the blade wheel is set upwards. A vent hole is arranged at the upper part of the pump body. A waterspout is arranged at the lower part of the pump body. Because the blade wheel inlet is set upwards, the direction of the acting force from the pumped medium to the blade wheel is upwards so as to balance the weight of the pump body and the motor rotation part elements, thus the rotation part elements are like to suspending in the medium. The bearing is not functioned by the axial force, thus reducing the bearing load and prolonging the bearing service life. In addition, a seal plug is on the balance hole of the blade wheel, thus avoiding the leakage in work. The vertical centrifugal pump has compact structure, balanced operation, energy-saving and low noise.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of vertical centrifugal pump.
Background technique
Existing vertical centrifugal pump impeller intake is downward, and medium is low in and high out by impeller during work, and the medium of being pumped produces a downward active force to impeller.The weight of moving elements such as impeller, pump shaft, motor rotor produces gravity downwards.These two power stack up and act on the bearing, make bearing axial load strengthen, thereby have shortened the working life of bearing, and the increase of resistance also can make noise strengthen consume electric power.In addition, have equalizing orifice on the impeller of existing vertical centrifugal pump, have leakage phenomenon when making work, reduced working efficiency.
Summary of the invention
The purpose of this utility model provides a kind of bearing and is not subjected to axial force to influence and increase the centrifugal pump of working efficiency, to solve the practical problem that existing product exists.
Structure of the present utility model is as shown in drawings: be made of the pump housing and motor.Have the pump housing 3 on the top of base.On the top of the pump housing one motor is arranged.On the output shaft of motor, have water retaining ring.Have seal ring at motor output shaft and pump housing connecting part.Bottom at output shaft has impeller.Have sealing plug on the equalizing orifice of impeller.The water intake of impeller upwards is provided with.Have exhaust port on pump housing top.Below the pump housing, have drain opening.At the two ends of the pump housing medium inlet and media outlet are arranged.Method of work of the present utility model is: actuating motor, and the impeller rotation, medium enters pump housing inner chamber by the medium inlet, enters the impeller inner chamber from the impeller top again.The centrifugal force that the impeller rotation produces throws away the impeller inner chamber with medium, flows out from media outlet.This product is owing to be that impeller intake upwards is provided with, and makes to be pumped force direction that medium produces impeller upwards.Thereby can balance the weight of the pump housing and motor rotating part component, like this, the rotating part component are as being suspended in the middle of the medium.Bearing is not subjected to the effect of axial force.Therefore alleviate the load of bearing, thereby prolonged the working life of bearing.In addition, because have sealing plug on the equalizing orifice of impeller, there is not leakage phenomenon when making work again.Improved working efficiency.Its compact structure, the operation balance, and have energy-conservation and the low characteristics of noise.
