The utility model discloses avoid the close easy weakness that lost efficacy and then influenced the antifriction bearing normal use life -span of mechanical seal effectively, lengthened submersible sewage pump's overhaul life effectively, guaranteed submersible sewage pump's life.
Description
Technical field
The utility model relates to a kind of pollution discharge pump, particularly relates to a kind of liquid sewage pump.
Background technique
Liquid sewage pump, in running, because motor and water pump bearing are apart from longer, easily produces pump shaft flexure, thus water pump bearing rapid wear.Simultaneously because the kinematic pair of water pump adopts rolling bearing to add mechanical seal combination, fear water-based weakness because rolling bearing has, be thus subject to the restriction of Reliability of Mechanical Seal the working life of rolling bearing.Cause bearing damage due to the inefficacy of mechanical seal under many occasions, thus directly affects the working life of liquid sewage pump.Especially, under the operating mode that under liquid, the degree of depth is longer, mechanical seal inefficacy has become the bottleneck that restriction liquid sewage pump normally runs.
Under clear water operating mode, water lubriucated bearing can be adopted to carry out alternative rolling bearing and can obtain good effect, but the medium that liquid sewage pump is carried contains more impurity, adopt to ensure the working life of common water lubrication mode bearing.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of liquid sewage pump, too be fixed against the reliability of mechanical seal its working life for the axis of rolling, and the feature of bearing rapid wear, the filtration of bearing, lubrication, cooling are combined, rolling bearing is substituted with sliding bearing, fed sheet of a media self is utilized to lubricate bearing, effectively avoid the close easy inefficacy of mechanical seal and then affect the weakness of rolling bearing normal service life, effectively extend the overhaul life of liquid sewage pump, ensure that the working life of liquid sewage pump.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of liquid sewage pump, it is characterized in that, described liquid sewage pump comprises oil sealing, impeller guide bearing, intermediate bearing, sub-propeller, drainage port, bottom spindle, upper joint-shaft, oil sealing is positioned at the bottom of bottom spindle, impeller guide bearing is enclosed within the lower outside of bottom spindle, intermediate bearing is enclosed within the upper outside of bottom spindle, upper joint-shaft is positioned at the top of bottom spindle, sub-propeller is enclosed within the outside of upper joint-shaft, and drainage port is positioned at the side of sub-propeller.
Preferably, described liquid sewage pump also comprises base, the pump housing, impeller, lower linking tube, bearing support, sleeve, upper connecting tube, bearing, motor cabinet, coupling, motor, mounting disc, outlet pipe, impeller is positioned at the below of bottom spindle, the pump housing is between base and impeller, lower linking tube is positioned at the side of impeller guide bearing, bearing support and intermediate bearing are fixed, sleeve is between bottom spindle and upper joint-shaft, upper connecting tube is positioned at the side of upper joint-shaft, bearing is positioned at the top of upper joint-shaft, motor cabinet and motor are fixed, be connected by coupling between motor with upper joint-shaft, mounting disc is fixed on the side of motor cabinet, one end of outlet pipe is connected with the pump housing, the other end of outlet pipe is connected with mounting disc.
Positive progressive effect of the present utility model is: the utility model is for the reliability being too fixed against mechanical seal working life of the axis of rolling, and the feature of bearing rapid wear, the filtration of bearing, lubrication, cooling are combined, rolling bearing is substituted with sliding bearing, fed sheet of a media self is utilized to lubricate bearing, effectively avoid the close easy inefficacy of mechanical seal and then affect the weakness of rolling bearing normal service life, effectively extend the overhaul life of liquid sewage pump, ensure that the working life of liquid sewage pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model liquid sewage pump.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model liquid sewage pump comprises oil sealing 1, impeller guide bearing 2, intermediate bearing 3, sub-propeller 4, drainage port 5, bottom spindle 9, upper joint-shaft 13, oil sealing 1 is positioned at the bottom of bottom spindle 9, impeller guide bearing 2 is enclosed within the lower outside of bottom spindle 9, intermediate bearing 3 is enclosed within the upper outside of bottom spindle 9, upper joint-shaft 13 is positioned at the top of bottom spindle 9, and sub-propeller 4 is enclosed within the outside of upper joint-shaft 13, and drainage port 5 is positioned at the side of sub-propeller 4.
The utility model liquid sewage pump can also comprise base 6, the pump housing 7, impeller 8, lower linking tube 10, bearing support 11, sleeve 12, upper connecting tube 14, bearing 15, motor cabinet 16, coupling 17, motor 18, mounting disc 19, outlet pipe 20, impeller 8 is positioned at the below of bottom spindle 9, the pump housing 7 is between base 6 and impeller 8, lower linking tube 10 is positioned at the side of impeller guide bearing 2, bearing support 11 is fixed with intermediate bearing 3, sleeve 12 is between bottom spindle 9 and upper joint-shaft 13, upper connecting tube 14 is positioned at the side of upper joint-shaft 13, bearing 15 is positioned at the top of upper joint-shaft 13, motor cabinet 16 is fixed with motor 18, be connected by coupling 17 between motor 18 with upper joint-shaft 13, mounting disc 19 is fixed on the side of motor cabinet 1, one end of outlet pipe 20 is connected with the pump housing 7, the other end of outlet pipe 20 is connected with mounting disc 19.
The utility model utilizes sliding bearing to substitute rolling bearing, eliminates this link of mechanical seal protection bearing, bearing lubrication is changed into water lubrication by oil lubrication, thoroughly overcomes the feature that rolling bearing fears water.Operationally medium carries out filtration by blocked sewage oil sealing to it and enters impeller guide bearing 2 and lubricate, enter intermediate bearing 3 to lubricate, for the raffinate of the nearly motor of partial compromise, accelerated by the back pressure of sub-propeller 4, release from drainage port 5 and enter cesspool import.The utility model, by changing the lubrication form of liquid sewage pump bearing, changes the lubricant medium structure of lubrication water pump bearing, to reach the overhaul life of prolongation liquid sewage pump and then to reach the object in working life increasing liquid sewage pump.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
