Description
Technical field
The utility model belongs to spinner-type flowmeter technical field, is specifically related to a kind of spinner-type flowmeter rotor, also relates to a kind of spinner-type flowmeter that above-mentioned rotor is housed simultaneously.
Background technology
Spinner-type flowmeter is the device calculating flow by measuring the rotatable parts (position) be located in direct current pipeline, is the one of variable area formula flowmeter.The structure of spinner-type flowmeter comprises a tapered tube expanded gradually from bottom to top and is placed in tapered tube and the rotor that freely up and down can rotate along the center line of pipe.When measuring fluid flow, detected fluid flows into from the lower end of tapered tube, and the impact flow of fluid rotor, and produces an acting force (size of this power changes with uninterrupted) to it; When flow is enough large, the acting force produced by rotor picking-up, and makes it to raise; Meanwhile, detected fluid flows through the annular section between rotor and tapered tube inwall, and at this moment acting on epitrochanterian power has three: fluid is to the dynamic pressure of rotor, rotor buoyancy in a fluid and the gravity of rotor self.During spinner-type flowmeter at right angle setting, rotor c.g. and tapered tube tubular axis coincide, and act on epitrochanterian three power all along the direction being parallel to tubular axis.When these three power reach balance, rotor just to float in tapered tube on a certain position reposefully.For given spinner-type flowmeter, rotor size and shape is determined, therefore its buoyancy in a fluid and self gravitation are all known is constant, has fluid only and changes the size of the dynamic pressure of float with incoming flow flow velocity.Therefore when incoming flow flow velocity becomes large or when diminishing, rotor will do movement up or down, and the flow cross-sectional area of relevant position also changes, until speed corresponding when flow velocity becomes balance, rotor is just stablized on new position.For a given spinner-type flowmeter, the size that the position of rotor in tapered tube and fluid flow through the flow of tapered tube becomes one-to-one relationship.
Spinner-type flowmeter has at production industries such as oil, chemical industry, medicine, food and uses widely.Because different actuating mediums has different physical and chemical performances, this just proposes corresponding requirement, as corrosion resistance, inoxidizability etc. to used spinner-type flowmeter.For meeting above-mentioned requirements, presently used spinner-type flowmeter mostly is the manufacture of the material such as glass, stainless steel, has served suitability for industrialized production well.But also there are some particular problems when reality uses, even if as used stainless steel material, some medium (as halogen-containing ionic medium) still can produce intercrystalline corrosion to austenitic stainless steel; In addition, some medium has very strong adhesion, and along with the carrying out produced can be attached on flowmeter tapered tube inwall and rotor, especially when stopping standing, this phenomenon is more obvious.Medium, to the corrosion of spinner-type flowmeter and attachment, not only affects the life-span of spinner-type flowmeter, also due to the structure of the inner structure and rotor that change spinner-type flowmeter, thus also drastically influence the accuracy of flow measurement.
Summary of the invention
