Description
Technical field
The present invention relates to a kind of flowmeter, especially plastic impeller Simple flowmeter.
Background technology
Flowmeter is one of instrument important in commercial measurement, in the market conventional flowmeter, is full of for measuring
Closed conduct, the liquid volume flow continuously flowed, but for viscosity is low, corrosion resistant liquid is not easy to measure, with industry
The progress of production, the requirement more and more higher of the degree of accuracy and scope to flow measurement, flow measurement technology are maked rapid progress, and are
Adaptation various uses, various types of flowmeters are come out one after another；The flowmeter that oneself comes into operation at present oneself more than 100 kinds；Modeling
Material propeller flowmeter oneself through belonging to a kind of more ripe technology, it is directed primarily to a kind of be applied to oil, chemical industry, smelting etc.
The flowmeter in field, in plastic impeller flowermeter when detected fluid flows through sensor, under fluid matasomatism, impeller by
Power rotates, and its rotating speed is directly proportional to pipeline mean flow rate, changes the magnetic resistance value of magnetoelastic transducer the rotation period of impeller.Detection
Generating period changes magnetic flux therewith in coil, produces periodic induced potential, i.e., electricity, which is plunderred, rushes signal, amplifies through amplifier
Afterwards, display instrument is delivered to show, and current its structure of plastic impeller flowmeter is relatively easy, therefore measuring accuracy is not high, surveys
It is unhappy to measure speed, growing industrialization development needs can not be met.
The content of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art and provide it is a kind of it is simple in construction, speed is fast, surveys
The accurate high plastic impeller flowmeter of amount.
To achieve these goals, the plastic impeller flowmeter designed by the present invention, including body, impeller assembly and display
Controller, inlet, liquid outlet and measurement pipeline, display controller are provided with body includes shell and control module, impeller
Component includes impeller base and blade assembly, and impeller base one end is stretched into measurement pipeline, and the other end is fixed on the outer of display controller
On shell, preamplifier is provided with impeller base, induction coil is provided with preamplifier, and the induction coil center is embedded with
Permanent magnet, amplifier is provided with the upper end of induction coil, and the control module in the display controller is electrically connected with amplifier
Connect, blade assembly includes blade seat, blade and the metal bar on blade of two on blade seat and the above；Leaf
Bar both ends are connected on impeller base by bearing.
Pass through the embedded metal bar among blade so that when hydraulic shock blade, driving moment is produced to blade, makes leaf
Piece overcomes moment of friction and fluid resistance square and produces the rotating speed of rotation blades by being detected mounted in impeller base inner inductive coil
Upon the rotation of the blade so that the metal bar in blade cuts the magnetic line of force as caused by the permanent magnet in impeller base, sense will be caused
Answer the flux change induction coils in coil that the magnetic flux mechanical periodicity signal detected is sent into preamplifier, signal is entered
Row amplification, shaping, produce the pulse signal directly proportional to flow velocity, and the control module being sent into display controller is obtained and shown tired
Product flow value.
Preferably, so as to play fixation, screw thread is provided with measurement pipeline opening, is cased with matching somebody with somebody with screw thread outside impeller base
Close fixed coupling nut.
In order to play sealing function, the part that measurement pipeline is stretched into impeller base is cased with sealing ring.
As preferred：The number of blade is four；By the design of preferred scheme, make global design reasonable, cut magnetic
Effect is more preferable during the line of force, so that good measuring accuracy.
Brief description of the drawings
Fig. 1 is the overall package figure of embodiment 1 in the present invention.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
