Description
Technical field
The utility model belongs to fluid metering technical field, is specifically related to duplex rotor meter.
Background technology
Rotor flow metering is one of ingredient of measuring science technology, and it and national economy, national defense construction, scientific research have close relationship.But original duplex rotor meter exists that flowmeter machine friction is large, serviceable life is short and to the weak shortcoming of viscosity B coefficent adaptability and volume is large, flow range is narrow; Running is uneven, noise greatly, not wear-resisting.This series of problem brings us and perplexs greatly.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide duplex rotor meter, solve that the flowmeter machine friction that existing flowmeter exists is large, serviceable life is short and weak to viscosity B coefficent adaptability, running is uneven, noise greatly, not wear-resisting problem, there is duplex rotor meter and have that measuring accuracy is high, smooth running, pulse free, noise are low, long service life feature.
To achieve these goals, the technical solution adopted in the utility model is: duplex rotor meter, includes housing, left rotor, right-hand rotation is provided with in housing, left rotor is connected with informing sheet by gear, and informing sheet is connected with gauge outfit by magnet coupler, is provided with upper cover plate above gauge outfit; Lower housing portion is provided with lower cover;
Described housing, upper cover plate, lower cover, left rotor and right-hand rotation composition measuring room, form the metering units of cavity as flowmeter of some known volume between them.
The beneficial effects of the utility model are:
Flowmeter of the present utility model is applicable to thin oil, lightweight oil, viscous crude, silt content is large, water cut is large crude oil, and the range of viscosities of measured liquid is large.The fluid flow maximum flow that flowmeter passes through is about two times of the common loading table of equal latus rectum.Long service life, accuracy is high, and reliability is strong.The pressure loss is minimum.Have mechanical counter, electronic counter two kinds, multiple output is available.As pulse, equivalent, 4-20MA, RS485, Hart agreement.
Duplex rotor meter indicates outside flow on the spot apart from direct-reading counter, also can connect pulse producer, converts the rotor number of revolutions be proportional to by flowmeter volumetric flow rate to pulse signal, can be connected with flow integrator or computing machine easily.There is the features such as measuring accuracy is high, smooth running, pulse free, noise are low, long service life.Volume is little, flow range is wide, reproducible; Rotor constant speed revolution, etc. flow, etc. torque; Wearing and tearing less, pulse free, viscosity strong adaptability; Life-span is long, easy to maintenance, and in petrochemical industry, traffic, the industries such as metallurgy have wide practical use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further detail.
See Fig. 1, duplex rotor meter, includes housing 3, and be provided with left rotor 7 in housing 3, turn right sub 9, left rotor 7 is connected with informing sheet 5 by gear 6, and informing sheet 5 is connected with gauge outfit 2 by magnet coupler 4, is provided with upper cover plate 1 above gauge outfit; Lower housing portion is provided with lower cover 8;
Described housing 3, upper cover plate 1, lower cover 8, left rotor 7 and son 9 composition measuring room of turning right, form the metering units of cavity as flowmeter of several known volume between them.
Principle of work of the present utility model is:
Duplex rotor meter metering section is primarily of measuring room and the helical rotor composition being contained in a pair design uniqueness in measuring room, they and measuring room form the cavity of several known volume, as flow metering unit, micro-pressure-difference drive rotor by flowmeter import and export rotates, often circle the volume of exportable 8 times of cavitys, the liquid of import is constantly delivered to outlet by rotor after cavity metering, through sealed coupler kinematic train, the revolution of rotor is passed to counting mechanism, directly indicate the total amount of liquid flowing through flowmeter.Also can distribution sublist head or configuration signalling generator and intelligent flow-integrating instrument, the Cumulate Sum instantaneous delivery of fluid volume can be shown.
The rotor of flowmeter leans on the small pressure reduction at its import and export place to promote to rotate, and constantly the liquid of import is delivered to outlet after cavity metering, number of revolutions is passed to counting mechanism through sealed coupler and kinematic train by rotor, directly indicate the total amount of liquid flowing through flowmeter, the revolution of helical rotor is by magnetic shaft coupling, and adjustment gear mechanism passes to gauge outfit counter.A pair helical rotor rotates under the pressure of liquid, and the enclosure space formed between rotor and metering chamber wall often turns round once discharges 8 times of shade volumes.Therefore according to this relation, as long as the pivotal number of times of metering rotor, flow accumulation amount can be calculated, according to revolution per second, can instantaneous delivery be measured.
The measuring room of flowmeter is made up of inner housing and a pair spiral rotor and upper and lower cover plates etc., and rotate under the pressure of liquid, form certain space between rotor and metering cavity wall, rotor often turns round the liquid of once discharging certain volume.According to the pivotal number of times of metering rotor, accumulation of fluid flow can be calculated; According to revolution per second, instantaneous delivery can be measured.
