Description

A kind of electromagnetic flowmeter quick hole punched device of silicon steel item
Technical field
The present invention relates to electromagnetic flowmeter production equipment technologies, and in particular to a kind of electromagnetic flowmeter is fast with silicon steel item Fast hole punched device.
Background technique
Electromagnetic flowmeter (Electromagnetic Flowmeters, abbreviation EMF) be 50~sixties of 20th century with The development of electronic technology and the new type of flowmeter developed rapidly.Electromagnetic flowmeter is to apply electromagnetic induction principle, A kind of instrument of conductive fluid flow, electromagnetic flowmeter are measured by the electromotive force inducted when externally-applied magnetic field according to conductive fluid Structure be mainly made of the part such as magnetic circuit system, measurement conduit, electrode, shell, lining and converter, magnetic circuit system:It is made With being to generate uniform direct current or alternating current magnetic field.DC circuit magnetic loop realized with permanent magnet, its advantage is that it is relatively simple for structure, by The interference of alternating current magnetic field is smaller, but it easily makes to make positive electrode by anion packet by the electrolytic liquid polarization in measurement conduit It encloses, negative electrode is surrounded by cation, i.e. polarization of electrode phenomenon, and internal resistance between two electrodes is caused to increase, thus is seriously affected Instrument works normally.When pipe diameter is larger, permanent magnet is accordingly also very big, heavy and uneconomical, so electromagnetic flowmeter Alternating magnetic field is generally used, and is that the excitation of 50HZ power frequency supply generates.
Measure conduit:Its effect is that tested conductive liquid is allowed to pass through.In order to make the magnetic line of force pass through magnetic flux when measurement conduit Amount is split or short circuit, and measurement conduit must use non-magnetic, low conductivity, low heat conductivity and the material with certain mechanical strength Material is made, and non-magnetic stainless steel, glass reinforced plastic, highstrenghtpiston, aluminium etc. can be selected.
Electrode:It is to draw and be measured directly proportional induced potential signal that it, which is acted on,.Electrode is generally used non-magnetic stainless Steel is made, and is required to flush with lining, unobstructed when passing through so as to fluid.Its installation site is preferably in the Vertical Square of pipeline To prevent precipitate bulk from influencing measurement accuracy above it.
Shell:It is made using ferromagnetic material, is the outer cover of distribution system magnet exciting coil, and the interference of external magnetic field is isolated.
Lining:On the inside of measurement conduit and flange sealing surface, have in one layer of complete electrically insulating substrate.It is directly contacted Fluid to be measured, effect are to increase the corrosion resistance of measurement conduit, prevent induced potential by metal measurement duct wall short circuit.Lining In material is mostly corrosion-resistant, high temperature resistant, wear-resisting polytetrafluoroethylplastic plastic, ceramics etc..
Converter:The induced potential signal given birth to by liquid flow movable property is very faint, influenced by various disturbing factors it is very big, The effect of converter is exactly that induced potential signal is amplified and converted to unified standard signal and inhibits main interference signal. Its task be electrode detection to induced potential signal Ex through amplification be converted into unified standard direct current signal.
The silicon steel item of existing electromagnetic flowmeter generally passes through manually hammering weldering by man-hour manually hand-held silicon steel sheet in punching Nail, to be punched out operation to silicon steel sheet, such mode causes operating efficiency lower.
