Abstract
The utility model relates to a water meter with a magnetic suspension structural impeller, which comprises a water meter casing body and a movement casing body. The water meter is characterized in that a movement shaft is arranged on a base of the case, an impeller bearing is sleeved at the position of an upper top point of the movement shaft, the impeller bearing is embedded into the lower end of an impeller shaft, the upper top point end of the impeller shaft corresponds to a bearing embedded into the inner side of an upper cover of a movement, a magnetic ring is disposed at the edge position of the upper end surface of the impeller shaft, a coupling sensing member is arranged on the outer side of the movement, a coupling magnetic ring corresponding to the magnetic ring on the upper end surface of the impeller shaft is disposed on the coupling sensing member, the coupling sensing member positioned inside an installing casing is a rotary member, and a rotary shaft disposed on the coupling sensing member is connected onto the installing casing via an upper bearing and a lower bearing. The water meter is characterized in that the coupling magnetic ring has the opposite polarity with the magnetic ring on the upper end surface of the impeller shaft. The water meter has the advantages of reducing frictional force of the impeller rotary shaft and guaranteeing rotary metering of the impeller when the flow is small as the coupling magnetic ring is capable of absorbing gravity of the impeller rotary shaft.
Description
Technical field
The utility model relates to a kind of water meter with magnetic suspension structure impeller.
Background technology
The sensitivity of rotor water gauge is determined by when rotated friction between movement and the impeller, when the duty of water meter at low discharge, the center of gravity of its impeller is downward, friction force concentrate on the impeller bottom end bearing and the movement datum axle that matches between, because the quality of impeller and the resistance of water, water meter is difficult to the drive impeller rotation under the condition of work of low discharge, thereby causes water meter not measure.Therefore demand developing the water meter movement that can adapt to low discharge urgently.
Summary of the invention:
The purpose of this utility model is that water meter turbine can't rotate existing the problems referred to above in the solution prior art when low discharge, and a kind of magnetic suspension structure of water meter turbine is provided.The utility model design has the water meter of magnetic suspension structure impeller, comprise water meter case, movement housing, it is characterized in that: a machine mandrel is arranged on the movement base, top place is with impeller bearing in machine mandrel, impeller bearing embeds the lower end of impeller shaft, the last center point of impeller shaft is with respect to the bearing that embeds the core upper cover inboard, there is a magnet ring in edge in the upper surface of impeller shaft, at the movement lateral surface one inductive coupling spare is arranged, on inductive coupling spare, have and the corresponding coupling magnet ring of the upper surface magnet ring of impeller shaft.It is characterized in that: inductive coupling spare is positioned at a mounting shell, and inductive coupling spare is a revolving part, and rotating shaft is arranged on inductive coupling spare, and rotating shaft is connected on the mounting shell by two bearings up and down.It is characterized in that: the coupling magnet ring is opposite with the polarity of the magnet ring of impeller shaft upper surface.The utility model has the advantages that the gravity that when low discharge, can adsorb impeller shaft, reduce the friction force of impeller shaft, wheel rotation metering when guaranteeing low discharge owing to the coupling magnet ring.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the A portion enlarged diagram among Fig. 1 of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise water meter case 1, movement housing 2 among the figure, it is characterized in that: a machine mandrel 4 is arranged on movement base 3, top place is with impeller bearing 5 in machine mandrel 4, impeller bearing 5 embeds the lower end of impeller shaft 6, the last center point of impeller shaft 6 is with respect to the bearing 8 that embeds core upper cover 7 inboards, in the upper surface of impeller shaft 6 edge one magnet ring 9 is arranged, one inductive coupling spare 10 is arranged, the upper surface magnet ring 9 corresponding coupling magnet rings 12 with impeller shaft 6 are arranged on inductive coupling spare 10 at the movement lateral surface.It is characterized in that: inductive coupling spare 10 is positioned at a mounting shell 13, and inductive coupling spare 10 is a revolving part, and rotating shaft 14 is arranged on inductive coupling spare 10, and rotating shaft 14 is connected on the mounting shell 13 by two bearings 11 up and down.It is characterized in that: coupling magnet ring 12 is opposite with the polarity of the magnet ring 9 of impeller shaft 6 upper surfaces.
Water meter of the present utility model is when meeting low discharge, because coupling magnet ring 12 is installed on the inductive coupling spare 10, and coupling magnet ring 12 is corresponding with the magnet ring 9 of impeller shaft 6 upper surfaces, their polarity is opposite, therefore the magnet ring 9 of impeller shaft 6 upper surfaces is coupled magnet ring 12 and attracts, the weight that makes impeller shaft 6 drop on the impeller bearing 5 reduces, thereby has reduced friction force, and impeller shaft 6 still rotates when guaranteeing low discharge.
