Abstract
The utility model relates to a peristaltic pump speed measuring mechanism. The utility model is characterized in that the speed measuring mechanism consists of a pump shaft 1, a discoid sheet 3 with a light transmission trough 2 at the periphery and firmly arranged on the pump shaft, and a photoelectric counter 4 arranged on the both sides of the discoid sheet 3; the quantities of the light transmission trough 2 on the discoid sheet 3 are 30 strips, or the light transmission trough 2 is a quantity setting which can make a convention relation with the circumference 360 degrees. Because the photoelectric sensing counting mechanism which is directly designed on the rotating shaft of the rotating pump is adopted, the utility model not only can record the rotating speed of the pump shaft directly, but also can get the rotation angle very ideally through the photoelectric sensing counter. The mechanism is not only simple, but also can also provide a reliable guarantee for the detection precision.
Description
Technical field
The utility model relates to a kind of speed measuring device, and especially a kind of peristaltic pump velocity measurement mechanisms that is used for belongs to pump speed pick-up unit class.
Background technology
At present in the detection for the running speed of all kinds of pump housings, generally all adopt electromagnetic induction device or far infrared deterctor to go to finish.In the application of reality, all can a device be installed in the rotary electric machine rotating shaft of pump, carry out the mensuration of rotating speed according to the different dried performances that causes.If carry out actual mensuration of rotation, often need scrambler and cooperate reading device to differentiate with it less than a circle.Obviously, this not only can increase the support equipment cost, and can increase the time of operation and loaded down with trivial details running program.
The utility model content
The purpose of the present utility model: be intended to propose a kind of velocity measurement mechanisms of brand-new peristaltic pump, require promptly that it is simple, needn't increase too many supporting cost, also can satisfy the requirement of certain rate accuracy simultaneously.
The velocity measurement mechanisms of this peristaltic pump is characterized in that: this velocity measurement mechanisms is by pump shaft 1 and the plate-like sheet 3 that is fixedly arranged on the pump shaft, periphery has light tank 2, and a photoelectric counter 4 formations that are arranged at these plate-like sheet both sides.
The quantity of the light tank 2 on the described plate-like sheet 3 should be able to be spent into the quantity setting of pact relation with circumference 360.
The velocity measurement mechanisms of this peristaltic pump that proposes according to above technical scheme, owing to adopt the optoelectronic induction counting mechanism that directly in the rotating shaft of rotating pump, directly designs, by the optoelectronic induction counter, can not only directly write down the rotating speed of pump shaft, and can obtain the anglec of rotation very goodly.This mechanism not only simply but also to accuracy of detection also can hold good security.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The velocity measurement mechanisms of this peristaltic pump as shown in the figure, it is a kind of inventive improvements to existing peristaltic pump measurement of rotating speed mechanism, its concrete technical scheme is: this velocity measurement mechanisms is by pump shaft 1 and the plate-like sheet 3 that is fixedly arranged on the pump shaft, periphery has light tank 2, and a photoelectric counter 4 formations that are arranged at these plate-like sheet both sides.
The quantity of the light tank 2 on the described plate-like sheet 3 should be able to be spent into the quantity setting of pact relation with circumference 360.
The quantity of the light tank 2 in general application on the related plate-like sheet 3 is good with 30 grooves.Because the angle between adjacent two grooves is expressed as 12 degree at this moment.
Claims (3)
1, a kind of peristaltic pump velocity measurement mechanisms is characterized in that: this velocity measurement mechanisms is by pump shaft (1) and be fixedly arranged on the pump shaft, periphery has light tank (2) plate-like sheet (3), and a photoelectric counter (4) that is arranged at these plate-like sheet both sides constitutes.
