Description
Technical field
The present invention relates to a kind of flowmeter, especially plastic impeller Simple flowmeter.
Background technology
Flowmeter is one of important instrument in commercial measurement, in the market conventional flowmeter, for surveying
Liquid volume flow of the amount full of closed conduct, continuous flowing, but low for viscosity, corrosion resistant liquid is not
It is easy to measurement, with industrial progress, the requirement of the degree of accuracy and scope to flow measurement is more next
Higher, flow measurement technology is maked rapid progress, and in order to adapt to various uses, various types of flowmeters are asked in succession
Generation；The flowmeter for having come into operation at present is more than 100 kinds；Plastic impeller flowmeter already belong to it is a kind of compared with
It is ripe technology, it is directed primarily to a kind of flowmeter for being applied to the fields such as oil, chemical industry, smelting,
In plastic impeller flowermeter when detected fluid flows through sensor, under fluid matasomatism, impeller stress
Rotation, its rotating speed is directly proportional to pipeline mean flow rate, and the rotation period ground of impeller changes the magnetic of magnetoelastic transducer
Resistance.Magnetic flux generating period change therewith in detection coil, produces periodic induced potential, i.e. electricity to plunder
Rush signal, after amplified device amplifies, deliver to display instrument and show, and current plastic impeller flowmeter its tie
Structure is relatively easy, therefore measuring accuracy is not high, and measuring speed is unhappy, it is impossible to meet growing industrialization
Development need.
The content of the invention
A kind of simple structure, speed are provided the invention aims to solve above-mentioned the deficiencies in the prior art
Hurry up, measure accurate plastic impeller flowmeter high.
To achieve these goals, the plastic impeller flowmeter designed by the present invention, including body, impeller sets
Part and display controller, are provided with inlet, liquid outlet and measurement pipeline on body, and display controller includes
Shell and control module, impeller assembly include impeller base and blade assembly, and measurement pipeline is stretched into impeller base one end
Interior, the other end is fixed on the shell of display controller, and preamplifier is provided with impeller base, in preceding storing
Induction coil is provided with big device, and the induction coil center is embedded with permanent magnet, in the upper end of induction coil
The control module being provided with amplifier, and the display controller is electrically connected with amplifier, and blade assembly includes
The blade and the metal bar on blade of blade seat, two on blade seat and the above；Blade seat two
End is connected on impeller base by bearing.
By the embedded metal bar in the middle of blade so that when hydraulic shock blade, to blade produces driving force
Square, makes blade overcome moment of friction and fluid resistance square and produce the rotating speed of rotation blades by mounted in impeller
Seat inner inductive coil causes that the metal bar in blade is cut by permanent in impeller base upon the rotation of the blade to detect
The magnetic line of force that magnet is produced, the magnetic that the flux change induction coils in induction coil will be caused to detect
Logical mechanical periodicity signal feeding preamplifier, is amplified, shaping to signal, and generation is directly proportional to flow velocity
Pulse signal, feeding display controller in control module obtain and show cumulative flow value.
Preferably, so as to play fixation, screw thread is provided with measurement pipeline opening, it is cased with outside impeller base
Coordinate fixed coupling nut with screw thread.
In order to play sealing function, the part for stretching into measurement pipeline in impeller base is cased with sealing ring.
As preferred：The number of blade is four；By the design of preferred scheme, make global design rationally,
Effect is more preferable during cutting magnetic line, so that good measuring accuracy.
Brief description of the drawings
