Description
Technical field
The utility model relates to a kind of pipeline mounted pump, specifically a kind of magneto drive pipeline mounted pump.
Background technique
The magneto drive pipeline mounted pump has compact structure, and floor space is little, operates steadily, and characteristics such as need not adjustment are installed.In addition, the import and export of magneto drive pipeline mounted pump are designed to the identical flange of specification, and two flanges are positioned at same center line, can be directly installed on the pipeline as valve, are convenient to line arrangement, and are easy for installation.The third aspect, the magneto drive pipeline mounted pump has substituted traditional envelope mode with static seal, has avoided leaking of fed sheet of a media, has complete leak free distinguishing feature.Therefore, the magneto drive pipeline mounted pump is specially adapted to the conveying of inflammable, explosive, poisonous and valuable medium.
For the riser pump, axial force has increased the deadweight of rotor, and axial force is increased, and downward with gravitational direction.And machine envelope formula pipeline mounted pump axial force is born by rolling bearing, and the magneto drive pipeline mounted pump is born by the end face thrust bearing, is born by axial force direction (magnet steel side end face thrust bearing in being generally).Excessive axial force is prone to cause thrust-bearing to wear and tear too early, influences the reliability and the working life of pump.
The model utility content
The utility model technical problem to be solved is, a kind of magneto drive pipeline mounted pump of axial force self-balancing is provided, and sets up Balance disc, realizes the autobalance of axial force, reduces the wearing and tearing of end face thrust bearing, improves the operating reliability of pump.
It is following that the utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of magneto drive pipeline mounted pump of axial force self-balancing comprises that the lower end has the pump shaft of impeller (6), and said pump shaft is installed in the sliding bearing through sliding shaft sleeve; Sliding bearing is installed on the bearing housing, and bearing housing is installed on the pump cover, and said pump cover offers the pump cover inclined hole; Said pump cover inclined hole lower end links to each other with the zone of high pressure of impeller; The upper end links to each other with the pump cover inner chamber, also comprises separation sleeve, and said pump shaft center is communicated with the inner chamber of separation sleeve on offering; Lower end and the pump shaft through hole that the suction port low pressure area of impeller links to each other is characterized in that: also comprise the last Balance disc that is installed on the pump shaft and be installed in the following Balance disc on the bearing housing; Said going up between Balance disc, following Balance disc and the said sliding bearing constitutes pressure chamber, and this pressure chamber has the pressure chamber inlet that communicates with the pump cover inner chamber, and this pressure chamber also is communicated with the inner chamber of separation sleeve through the end clearance between last Balance disc and the following Balance disc.
Also comprise the back shroud of impeller that is positioned at the impeller top, and be separately installed with the end face thrust bearing on this back shroud of impeller and on said on the Balance disc.
The good effect of the utility model is: the structure that adopts the utility model; High-pressure medium in the pump chamber gets into the pump cover inner chamber by the inclined hole on the pump cover; Pressure chamber inlet under the warp on the Balance disc gets in the pressure chamber; Get into the inner chamber of separation sleeve again by the gap between the Balance disc end face up and down, be back to the suction port low pressure area of impeller at last by the inner chamber of separation sleeve through the pump shaft through hole.When described end clearance hour, pressure in pressure cavity is suitable with pump chamber inner high voltage district pressure, and the separation sleeve chamber pressure is very low, rotor total stressed upwards; Balance disc in the picking-up increases described end clearance, and pressure chamber pressure reduces; The separation sleeve chamber pressure increases, and rotor is total stressed downward again, magnet steel and last Balance disc in pressing down; Described end clearance is reduced, little of to a certain degree again because of variation in pressure increases, be stabilized in a suitable gap at last; Realized the transient equiliblium of axial force, both sides end face thrust bearing is not contacted basically, do not worn and torn.
