Description

A kind of novel anti-stuck turbine flowmeter of impeller

Technical field

The utility model is related to flow-meter technical fields, more particularly to a kind of novel anti-stuck turbine flow of impeller Meter.

Background technology

Currently, vortex-shedding meter becomes one of essential equipment in detection process, it is according to Karman vortex street principle It researchs and produces, is mainly used for the flow measurement of industrial pipeline medium fluid, no moving machinery part, therefore reliability height, dimension Shield amount is small, can long-term stable operation.With the continuous development of vortex-shedding meter, vortex-shedding meter is obtained extensively with its unique advantage General application.

The operation principle of turbine flowmeter is to feel at ease to fill a turbine in the duct, and both ends are by bearing support, when fluid is logical When overcurrent gauge pipeline, impulse turbine blade drives kinetic moment to turbine generation, turbine is made to overcome moment of friction and fluid resistance square And rotation is generated, in certain range of flow, to the angular velocity of rotation and fluid flow rate of certain fluid viscosity turbine at just Than, thus can calculate by fluid flow.

But traditional turbine flowmeter is easy that trip impeller is stuck to be unable to measure when measuring fluid containing impurity Phenomenon, and fluid flow direction is also required, therefore use restricted bigger；Strainer in existing turbine flowmeter It is that fitting measures inside pipe wall setting mostly, although contaminant filter can be avoided abrasion of the impurity to measuring cell by this structure, But strainer front end accumulates a large amount of sundries and blocks measurement pipe after being used for a long time, and needs to deactivate and retracts cleaning, seriously affecting makes With effect, it is badly in need of improving.

Invention content

In view of this, the utility model provides a kind of novel anti-stuck turbine flowmeter of impeller, can filtration volume it is larger Sundries, and impeller be not easy to it is stuck.

The utility model is solved the above problems by following technological means：

The novel anti-stuck turbine flowmeter of impeller of the utility model, including measurement pipe, inside the measurement pipe Eddy generator and sensor probe with respect to installation, is set to the survey at the conical screen set on the eddy generator front end The support conduit communicated with the measurement pipe above buret and the integrating instrument set on the support conduit upper end, the biography The signal amplifier that the output end of sensor probe passes sequentially through in the support conduit is connect with the integrating instrument, the sensor The outside of probe is equipped with probe sleeve, and the sensor probe is fixed on by the probe sleeve under the support conduit End, the lower end of the sensor probe are stretched into the measurement pipe, and the measurement inside pipe wall of the sensor probe front end is equipped with Symmetrically arranged two fixture blocks；

The eddy generator includes cylinder outer race, the central rotating shaft at the cylinder outer race center, by the center Shaft is mounted on impeller in the cylinder outer race, the card slot that is symmetrically set on the outside of the cylinder outer race, and the card slot blocks for being inserted into Block is to fix the eddy generator.

Further, multiple blades of the impeller are along the axial direction setting of the central rotating shaft.

Further, multiple blades are the narrow structure in the wide head in root, and the head of the blade is arcuate structure.

The novel anti-stuck turbine flowmeter of impeller of the utility model is carried out the larger impurity of volume by conical screen Filtering, the impurity of filtering are flowed through along gap of the taper surface between eddy generator and measurement pipe, to not only effectively avoid Large-scale sundries is to the stuck of impeller or even damage, it is thus also avoided that the case where traditional strainer easily causes blocking, extending continuously makes With time and service life；Fixture block is inserted into card slot, eddy generator is fixed, is easily installed and dismantle.

Specific implementation mode

In the description of the present invention, it should be understood that term "center", "upper", "lower", "front", "rear", The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indicates or imply and is signified Device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to this practicality Novel limitation.

The utility model is described in detail below with reference to attached drawing：Novel anti-impeller 33 described in the present embodiment is stuck Turbine flowmeter, including measurement pipe 1, the opposite eddy generator 3 and sensor probe installed inside the measurement pipe 1 4, communicating with the measurement pipe 1 set on the conical screen 5 of 3 front end of the eddy generator, above the measurement pipe 1 Conduit 6 and the integrating instrument 7 set on 6 upper end of the support conduit, the output end of the sensor probe 4 is supported to pass sequentially through Signal amplifier in the support conduit 6 is connect with the integrating instrument 7, and the outside of the sensor probe 4 is equipped with probe sheath Pipe 8, the sensor probe 4 are fixed on the lower end of the support conduit 6, the sensor probe 4 by the probe sleeve 8 Lower end stretch into the measurement pipe 1, two be provided symmetrically on 1 inner wall of measurement pipe of 4 front end of the sensor probe Fixture block 2；The eddy generator 3 includes cylinder outer race 31, the central rotating shaft 32 at 31 center of the cylinder outer race, by described Impeller 33 that central rotating shaft 32 is mounted in the cylinder outer race 31, the card slot 34 for being symmetrically set in the outside of the cylinder outer race 31, it is described Card slot 34 fixes the eddy generator 3 for being inserted into fixture block 2.
