Closing between seal casinghousing place end face and seal casinghousing of described dividing plate is furnished with seal ring.
The beneficial effects of the utility model are:
1), abandoned traditional mechanical transmission structure, by adopting magnetically-actuated mode, rely on the mode that adds barrier assembly between pump housing pump chamber and Power Component, thereby play rigid physical seal effect between the two.In the time that reality is used, pump chamber is as the circulation passage of liquid dielectric, itself in moment be perfused with a large amount of liquid dielectrics, by the effect of dividing plate, liquid dielectric is able to flow along set direction all the time, even if there is huge hydraulic pressure, also can not break through the dividing plate of physical seal and have influence on the operating stably of Power Component; And Power Component is as the power input part of pump shaft, be able to actv. because of the mode of above-mentioned magnetic attraction again and realize the transmission object of kinetic energy and moment of torsion, its simple in structure and be easy to realize, can realize good machine work object even simultaneously the same in high hydraulic pressure environment, applicable surface is obviously higher than conventional gears type of drive.
2) on the basis of the bearing fit structure, adopting merely at old-fashioned traditional water jet propulsion pump, utilize on the one hand the single supported beam pump shaft structure that current structural behaviour is the most stable, guarantee the functional reliability of whole pump shaft, with the real work vibration of avoiding as far as possible, guarantee minimumization of its operating noise and the stability of serviceability, on the other hand, what overcome that current single supported beam pump shaft structure unavoidably produces is excessive because take turns pump housing exhalant region hydraulic pressure under high velocity effect at movable vane, and matching loose and even obscission that the exhalant region bearing assembly producing and even other corresponding matching components occur along hydraulic thrust direction, by this return flow line structure of the hollow pump shaft of adoption of innovation, also current feedback channel is set being easy to the loosening bearing assembly position of production part, thereby in the water lubricating object for bearing assembly in the time having guaranteed that liquid dielectric is flowing, also utilize the characteristic of pump shaft as return flow line, the lubrication gap place that treats that makes to act on bearing assembly is also in it, the high-pressure liquid medium of outer ring gap location is back to the pump housing inhalant region of relatively low pressure automatically along return flow line, and then play the slow pressure buffering effect for corresponding component under high hydraulic pressure environment, work of the high-effect and long life object of the final whole exhalant region inner component that has effectively guaranteed the pump housing.
3), for the affixed single supported beam structure of the equal bearing in two ends of pump shaft, concrete be that between the bottom of the barrel of one end and the barrel-shaped pump housing, bearing is affixed, and between the inlet guide vane at the other end and pump housing bung place, form bearing fit; When waterjet propulsion pump work, the liquid dielectric of exhalant region is in its spout ejection, partially liq medium also flows into the bearing assembly place of inlet guide vane and plays lubricating effect, this partially liq medium lubricating bearings assembly behind lubrication gap, naturally be back to pump housing inhalant region along the tubbiness vestibule of inlet guide vane and by the internal cavities of hollow shaft shape pump shaft, thereby complete the hydraulic pressure buffering object for bearing assembly; Because bearing assembly no longer bears excessive hydraulic pressure, even without how high setting accuracy, itself functional reliability can greatly be guaranteed, it is installed and makes and even maintenance cost all can effectively reduce.
4), the material of dividing plate own, be preferably the non-magnetic material that is easier to realize magnetic action, thereby its work efficiency is guaranteed in the magnetic force loss when reducing magnetic and penetrating.And the sealing means of concrete dividing plate is selected with the tight face between seal casinghousing and pump case, against coordinating, to rely on both faces to realize sealing purpose between the two against mode on the one hand herein, stop both under high pressure water environment and coordinate gap leakage problem; On the other hand, coordinate centre place sandwiched dividing plate by its face, seal successively against effect to realize its three.When actual use, can consider only to add seal ring at dividing plate and seal casinghousing cooperation place, to guarantee the isolation antiseepage object at Power Component place place; As between dividing plate and pump chamber, because pump chamber itself is in water environment, therefore without sealing, to simplify its structure and maintenance cost.
5), the arrangement of Power Component and pump shaft opposing end surface, the card symmetrical structure that can regard as time, both form take dividing plate as the plane of symmetry, thus by increasing both card areas, to promote and to guarantee power input efficiency between the two.
6) when, reality is used, discoid end face on the power input shaft of pump shaft and even Power Component all can be arranged to and axial region main body between separable Demountable, to play the simplification of further guaranteeing its mounting process in its actual cost of manufacture reducing; As above-mentioned in this paper only needs the two sides of magnetic cooperation and magnetic sleeve portion is set with it, thereby avoided the problem of the power input shaft of whole pump shaft and even whole Power Component being arranged to be that magnetic texure produces expensive and being difficult to actual assembled, its structure realizes more simple and is suitable for.
