As a kind of preferred version of the present utility model, pass through scyewed joint between described balance tube and the described cover plate.
As a kind of preferred version of the present utility model, also be provided with an air ring between described balance tube and the described cover plate.
As a kind of preferred version of the present utility model, the described cover plate tabling of an end of described air ring, its other end and described balance tube tabling.
As a kind of preferred version of the present utility model, the cross section of described Balance disc is I shape.
As a kind of preferred version of the present utility model, also be provided with a Sealing between described taper sheath and the described pump shaft.
As a kind of preferred version of the present utility model, described Sealing can be a rubber bar.
As a kind of preferred version of the present utility model, described going up is penetrated with a leakage pipe on the blower inlet casing, and it is provided with a water intake in described contacting point of going up blower inlet casing and described pump shaft, and another end outside last blower inlet casing is provided with a water outlet.
As a kind of preferred version of the present utility model, also be equiped with a plug in the end of described pump shaft and described going up between the blower inlet casing.
Technique effect of the present utility model is to make submersible pump under the situation that does not change its flow and lift, has significantly reduced the axial force between graphite and the thrust disc, thereby can effectively prolong submersible pump working life.And the utility model is simple in structure, and is easy for installation, and practical effect is strong.
Description of drawings
Below in conjunction with accompanying drawing and better embodiment the utility model is described in further detail.
Fig. 1 is the sectional drawing that diving pump axial force of the present utility model is eliminated valve one better embodiment.
Embodiment
Referring to accompanying drawing 1, this model utility diving pump axial force is eliminated between the pump shaft 10 that valve is installed in the last blower inlet casing 9 of submersible pump and submersible pump, this diving pump axial force is eliminated valve and is comprised: a balance tube 12, itself and last blower inlet casing 9 weld together, and with the cover plate 7 of submersible pump with scyewed joint; One Balance disc 5, it is positioned on the cover plate 7, and leaves axial clearance with balance tube 12, and water can flow out from this axial clearance during the submersible pump running; One is installed in the taper sheath 4 between the pump shaft 10 of Balance disc 5 and submersible pump, and this taper sheath 4 and Balance disc 5 are connected with the inclined-plane, can make Balance disc 5 location like this and clamp pump shaft 10.Also be provided with a Sealing 3 between taper sheath 4 and the pump shaft 10, sealing part 3 can be a rubber bar.Also be provided with an air ring 6 between balance tube 12 and the cover plate 7, this air ring 6 can be the copper end ring; One end of this air ring 6 and cover plate 7 tablings, its other end and balance tube 12 tablings.Last blower inlet casing 9 upper ends are penetrated with one and reveal pipe 2, and its end in last blower inlet casing 9 and pump shaft 10 is provided with a water intake, and another end outside last blower inlet casing 9 is provided with a water outlet.End and described going up between the blower inlet casing 9 in described pump shaft 10 also are equiped with a plug 1.
Submersible pump in working order down, the source, water source of high pressure constantly flows into from the slit of 10 of cover plate 7 and pump shafts, and is filled between Balance disc 5 and the cover plate 7, thereby forms a high hydraulic pressure district.Yet, the top of Balance disc 5 does not promptly have water by described pump shaft 10, plug 1, last blower inlet casing 9, balance tube 12, Balance disc 5 and taper sheath 4 zone that forms that surrounds, thereby does not have hydraulic pressure yet at this moment, so, consequent pressure difference is upwards lifted Balance disc 5, simultaneously, and by the clamping action of 4 pairs of pump shafts 10 of taper sheath, driving pump shaft 10 upwards mentions, rotor shaft is also and then mentioned simultaneously, thrust disc is just separated with graphite, thereby reduced friction between the two.After Balance disc 5 is upwards mentioned, and the slit is just arranged between the copper end ring 6, water is extruded from this slit, upwards extrudes along the axial clearance between Balance disc 5 and the balance tube 12, flows out along revealing pipe 2 at last.Water above the Balance disc 5 can arbitrarily flow out along revealing pipe 2, so the pressure above the Balance disc 5 is all the time very little, thus, as long as Balance disc 5 below have water to enter, the pressure difference of Balance disc between about in the of 5 exists all the time, and Here it is utilizes self high pressure water to eliminate the overall process of axial force.
After adding this device on the submersible pump, utilize the water of the high pressure of self that pump shaft is mentioned, finally make and separate a little between thrust disc and the graphite, thereby slowed down wearing and tearing between the two, played the effect of eliminating axial force.
Below preferred embodiment of the present utility model is specified, but the utility model is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
