Detailed Description
In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.
Specific embodiments of the present invention are described below with reference to the accompanying drawings.
Examples
As shown in fig. 1-3, a high pressure resistant precession vortex flowmeter for oil field includes a measuring cylinder 3, a connecting flange 2 is welded and fixed at the left end and the right end of the measuring cylinder 3, a fixing base 1 is fixed at the upper end of the measuring cylinder 3 through bolts, a measuring meter 4 is fixed at the upper end of the fixing base 1, a straight blade rotator 31 includes a rotating shaft 312, and a rotating blade 311 is fixed on the surface of the rotating shaft 312.
Become straight blade through with original vortex generating body and play and revolve ware 31, reduce entry and inflow contained angle, thereby reduce fluidic resistance, make inside the fluid can get into barrel 33 smoothly, it is few to straighten blade and play spiral ware 31 surface rotating vane 311 simultaneously, the damage of rotating vane 311 under the fluid high pressure condition of avoiding that can be fine, the fluid removes along rotating vane 311, simultaneously by the production swirl of being driven, thereby make things convenient for the detection sensor 34 at rear to detect, the fixed straight blade plays the fluidic flow direction of change that spiral ware 31 can be fine, reduce fluidic pressure and play the extrusion of spiral ware 31 to the straight blade, make the fluid normally pass through.
The working principle is as follows: after the invention is installed, when the invention is needed, the connecting flange 2 is connected on the surface of the external pipeline through the external bolt, the external pipeline is controlled to supply fluid to the inside of the measuring cylinder 3, the fluid enters the inside of the measuring cylinder 3, the fluid entering the inside of the measuring cylinder 3 moves on the surface of the straight blade spinner 31 and is guided by the rotating blade 311 to rotate, when the fluid enters the diffusion section, the vortex flow is refluxed to start to rotate for the second time, a gyro type vortex precession phenomenon is formed, the precession frequency is in direct proportion to the flow size and is not influenced by the physical property and the density of the fluid, the secondary rotation precession frequency of the fluid measured by the detecting sensor 34 can obtain good linearity in a wider flow range, the signal is amplified, filtered and shaped by the preamplifier to be converted into a pulse signal in direct proportion to the flow speed, and then the pulse signal is sent to the microprocessor for integration processing together with the detecting signals of temperature, pressure and the like, the results are finally shown in table 4.
