In addition, mechanical seal is had relatively high expectations to water and pump working stability, has vibration all may damage mechanical seal when the work of the impurity or the pump housing is arranged in the water, causes mechanical seal to be lost efficacy, thereby influences pump performance.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rotating speed and linear velocity that improves pump shaft, increases the flow of water pump and the highly effective energy-conserving vertical water pump of lift.
Technical solution of the present utility model is: it comprises the lower support frame and the pump housing that is fixed on the lower support frame, be fixed with upper bearing bracket in pump housing upper end, at the pump housing lower end mouth internal fixation lower bearing body is arranged, on the pump housing, vertically be penetrated with pump shaft, between lower bearing body and upper bearing bracket and pump shaft, be separately installed with bearing, on pump shaft, be positioned at the pump housing black box and impeller are installed, on the pump housing, be supported with the motor that is connected with pump shaft by upper bracket, its special way is: the annular oil cavity of dress lubricant oil in bearings mounted inner chamber periphery is provided with on upper bearing bracket, annular oil cavity is by being fixed on the end bracket enclosed on the upper bearing bracket, and annular oil cavity is communicated with bearings mounted inner chamber on the upper bearing bracket.
Above-mentioned highly effective energy-conserving vertical water pump is provided with the oil inlet hole that communicates with annular oil cavity on end cap, be provided with plug cock in oil inlet hole.
Above-mentioned highly effective energy-conserving vertical water pump is positioned at the bearing lower end and is provided with the oil-through hole that is communicated with annular oil cavity and bearing cavity is installed on upper bearing bracket.
Above-mentioned highly effective energy-conserving vertical water pump, described black box is by being installed in the pump housing and being enclosed within stuffing box body on the pump shaft, being located in the stuffing box body and the stuffing box packing between the pump shaft and the Gland that is fixed on the stuffing box body constitute, damage sealing, good sealing effect when avoiding impurity or pump housing work are arranged in the water vibration is arranged.
Above-mentioned highly effective energy-conserving vertical water pump is equipped with a cover bearing between upper bearing bracket and pump shaft, so that processing and assurance concentricity.
The utility model has the advantages that: because the annular oil cavity of dress lubricant oil in bearings mounted inner chamber periphery is provided with on upper bearing bracket, annular oil cavity communicates with bearings mounted inner chamber on the upper bearing bracket, therefore the bearing that is installed between upper bearing bracket and the pump shaft has been realized oil lubrication, high lubricating effect, can improve the rotating speed and the linear velocity of pump shaft, increase the flow and the lift of water pump, improve the working efficiency of water pump.
