Description
Technical field
The invention belongs to the flow measurement instrument of the rate-of flow in the closed conduct, particularly be applicable to a kind of bundled tube coriolis mass flowmeters of measuring heavy caliber stream pipe.
Background technology
At present, in order to measure the mass of medium flow in the closed conduct, usually adopt linear tube Coriolis mass flowmeter or " U " type tube coriodis mass flow meter, " U " type tube coriodis mass flow meter wherein, its structure comprises: at the stream pipe top of determined fluid installing " U " type measuring tube, one end of " U " type measuring tube is joined to locating to be communicated with stream pipe importer, the other end of " U " type measuring tube is communicated with stream pipe Way out place and joins, at the electromagnetic driver that middle part installing in " U " type measuring tube top is made up of coil and magnet, outside two arms at " U " on driver both sides type measuring tube top, all install by coil and magnet and form signal transducer.Two arms that drive " U " type measuring tube by electromagnetic driver resonate with opposite phases mutually, come detected phase poor with signal transducer.When the measurement bore is " U " type coriolis mass flowmeters of DN250, its physical dimension is 1.7 meters X2 rice, this is can't satisfy the user in the requirement of industry measurement, even also need enough big scene when installing, both inconvenience was installed, in debugging and daily servicing operation a lot of inconvenience is arranged simultaneously, and the investment cost height.Usually adopt " U " type coriolis mass flowmeters, the cast of each production firm is different, and after cast was determined, the maximum caliber of this cast had also just been determined, as the above-mentioned DN250 that is to the maximum; Main cause is that the more big measuring tube of bore is also more big, and needed driving force is also more big, and measuring tube just can't drive again when bore arrived to a certain degree, and its volume is excessive simultaneously also can't process, and both has been not easy to install, and is not easy to operation and investment cost height again.Therefore research and development both had been applicable to the flow measurement of heavy caliber stream pipe, were applicable to the flow measurement of osculum runoff pipe again, and, have the installation and maintenance of being convenient to, investment cost low, a kind of novel bundled tube coriolis mass flowmeters is very necessary.
Summary of the invention
The present invention is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide a kind of not only reasonable in design, compact conformation, can be by the effect of tube bank steady flow condition, it is identical to make fluid enter the flow that flows through medium of each measuring tube again, both has been applicable to the flow measurement of heavy caliber stream pipe, be applicable to the flow measurement of osculum runoff pipe again, and it is little to have a volume, is convenient to installation and maintenance, and investment cost is low and use a kind of bundled tube coriolis mass flowmeters very easily.
The objective of the invention is to adopt following technical scheme to realize: described bundled tube coriolis mass flowmeters, comprise electromagnetic driver, signal transducer, stay pipe and measuring tube, it is characterized in that: the advancing of described stay pipe, outlet is all installed shunting disk in the two ends, connect the bundled tube measuring tube of straight pipe type or the bundled tube measuring tube of straight tube tripe type in described two shunting disks, the bundled tube measuring tube of described straight pipe type is the measuring tube of the straight tube shape more than 2 by arrangement mode at number of connection on two shunting disks, is the measuring tube of the straight tube tripe shape more than 2 at number of connection on two shunting disks by arrangement mode on inherent two shunting disks of the stay pipe of described straight tube tripe type bundled tube measuring tube; And measure with the mass rate of one or more pairs of measuring tube convection cells, at the middle part installing electromagnetic driver of every pair of measuring tube, at electromagnetic driver both sides installing signal transducer.
The arrangement mode of described measuring tube in stay pipe is divided into single-layer type and multiple field, and described single-layer type is to be arranged as individual layer along inside pipe wall by a plurality of measuring tubes; Described multiple field is to be arranged in multilayer more than 2 layers or 2 layers by a plurality of measuring tubes in pipe.
Principle of the present invention and operation are described below:
The present invention is current stabilization principle, the organic combination of Coriolis principle with the tube bank stream field, distributes in tube bank and adopts Chebyshev's distribution and logarithm-linear distribution method, so just can determine reasonably tube bank quantity according to the pipeline flow scope.Therefore because the present invention adopts the measuring tube of bundled tube, therefore the effect of steady flow condition is arranged, and bundled tube section formula mass flow meter measurement mode is to utilize a pair of vibration tube or many to the rate-of flow in the vibration tube measuring channel, Media density, by measuring a pair of vibration tube or many mass rates that the flow of vibration tube is finally obtained pipeline internal medium.Measuring method is very easy.
The technical scheme of to sum up taking realizes purpose of the present invention.
Compared with prior art, the present invention is not only reasonable in design, compact conformation, can be by the effect of tube bank steady flow condition, it is identical to make fluid enter the flow that flows through medium of each measuring tube again, both has been applicable to the flow measurement of heavy caliber stream pipe, be applicable to the flow measurement of osculum runoff pipe again, and it is little to have a volume, is convenient to installation and maintenance, and investment cost is low and use advantages such as very convenient.
