Description
Technical field
The utility model relates to a kind of detecting device for liquid flow, the turbine that is specifically related to a kind of turbo flow meter and uses in turbo flow meter.
Background technology
Turbo flow meter is a kind of device of tracer liquid flow, generally includes a tubular shell, in pipeline center, lays a turbine, also claims impeller, and two ends are by bearings.When fluid is when the pipeline, impulse turbine blade, produces driving moment to turbine, makes turbine overcome friction square and fluid resistance square and produces rotation.In certain flow range, to certain fluid media (medium) viscosity, the angular velocity of rotation of turbine is directly proportional to rate of flow of fluid.Thus, rate of flow of fluid can obtain by the angular velocity of rotation of turbine, thereby can calculate the fluid flow by pipeline.
Wherein, the rotating speed of turbine records by magnetoelastic transducer, and when ferromagnetic turbo blade process iron, the magnetic resistance of magnetic circuit changes, thereby produces induced signal.Signal amplifies and shaping through amplifier, delivers to counter or frequency meter, shows total integrating flow.Simultaneously by pulsed frequency through overfrequency-voltage transitions with indication instantaneous delivery.The rotating speed of turbine is proportional to flow, and the revolution of turbine is proportional to the total amount flowing through.
Therefore, turbine of the prior art adopts permeability magnetic material (normally magnetic stainless steel) to make, and conventionally adopts metal casting technique processing, and the cost of raw material is high, processing time consuming, and the dynamic balance performance of product has difficulty for manufacturing and detecting.On the other hand, for not affecting the rotation of turbine, the terminal of testing circuit is usually located in the hole of housing, aims at blade and detects, and in pipe inner wall fouling or water, in sparkling situation, may cause accuracy of measurement to decline.
Summary of the invention
The purpose of the present utility model is to provide a kind of turbine that improves structure, to reduce costs and difficulty of processing, makes the detection terminal of turbo flow meter can extend in pipeline simultaneously, improves the accuracy of measuring.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of turbine, comprise axis body and be arranged on a plurality of blades on axis body, described axis body is by impeller section and two sections of plastics axis bodies that form of detection segment, described blade is fixedly connected on impeller section, and described detection segment surface distributed has a plurality of caulking grooves, the relative axis body radial arrangement of caulking groove extending along axis body length direction described in each, on the xsect of axis body, each caulking groove is circumferentially uniformly distributed; With described caulking groove form fit, be provided with magnetic conduction inserts, described magnetic conduction inserts be embedded in caulking groove and with axis body wringing fit.
In technique scheme, turbine is two-part structure, and impeller can adopt non-magnetic plastics to make, therefore, on the whole, can be by axis body (comprising impeller section and detection segment) and blade integrated injection molding, in detection segment, embed magnetic conduction inserts again, for magnetoelectricity, detect.Because blade does not need metal casting, magnetic conduction inserts can adopt plate armature, does not affect detection and is convenient to again processing.On the other hand, the impeller section at blade place is separated with detection segment, and detection terminal can stretch into pipe interior and not affect blade rotation, the problem that while having solved in pipe inner wall fouling or water with gas, measurement accuracy declines.
Further technical scheme, is provided with the connectivity slot that is communicated with caulking groove described in each in the end of axis body detection segment, described magnetic conduction inserts consists of the clamping ring coordinating with connectivity slot and a plurality of magnetic conduction dummy slider one coordinating with each caulking groove respectively.Utilize clamping ring that each magnetic conduction dummy slider is linked into an integrated entity, be both convenient to install, can avoid again the problem that in use magnetic conduction dummy slider departs from.
A kind of turbo flow meter, mainly by housing, the guide plate, the magnetoelastic transducer that are arranged on turbine in housing pipeline, fix with housing and are connected with turbine bearing, formed, adopt said structure turbine, described housing is provided with installation through hole, the test side of described magnetoelastic transducer is stretched in pipeline through described installation through hole, and aims at the detection segment of described turbine.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. turbine of the present utility model is Split type structure, and integral body can be used plastics standby, and only dummy slider is prepared by permeability magnetic material, and therefore, Impeller Machining convenient formation has been saved permeability magnetic material simultaneously.
2. the utility model divides detection segment and impeller section to be arranged, and detection terminal can be stretched in pipeline and does not affect the rotation of blade, therefore, can in pipe inner wall fouling or water, be with under vaporous condition and realize accurately and measuring.
