Description
Technical field
The present invention relates to fields such as chemistry, flowmeters, specially a kind of sprayed on material and the electromagnetic flowmeter without liner.
Background technology
It is to add an electric field, stream to fluid that electromagnetic flowmeter, which generally has one group of coil and two electrodes, the effect of coil,
Dynamic conducting liquid is equivalent to a conductor, can accordingly be generated when conductor cutting magnetic line according to Faraday's electromagnetic induction law
One electromotive force directly proportional to speed, the effect of electrode is exactly to measure this induced electromotive force, so only electricity in measurement pipe
Pole is connected with conducting liquid, and other parts are liners, it is ensured that insulation, electromagnetic flowmeter could work normally.If there is
That section of metallic conduit in magnetic field is also in contact with liquid, short-circuit between conducting liquid and metal tube that electromagnetic flowmeter is surveyed,
Conduction is just had, will guide potential makes electromagnetic flowmeter be unable to measure potential.So the inside of existing electromagnetic flowmeter
All it is to have lining.By the difference with liner material so that the use of electromagnetic flowmeter has certain restricted.And according to using
The difference of water quality and environment, liner also divide many different types such as：Rubber, polytetrafluoroethylene (PTFE) etc., this allow for production with
It is often inadequate to the level of understanding of product and during choosing, cause type selecting mistake, product to reach the case where scene can not use
Occur or some water quality conditions cause liner to wear, corrosion etc. causes to measure inaccurate.Existing liner is used in sanitary sewage
On can meet the requirements, but once use the problem of industrial wastewater is due to material itself, will result in corrosion, wear etc. and drop significantly
The service life of low electromagnetic flowmeter and the accuracy of measurement.This allows for necessarily requiring to entirely to have using technique pre-sales
Detailed understanding, and it is unable to Replacement procedure or water quality in use, design comparison is inflexible.
Invention content
The purpose of the present invention is：A kind of sprayed on material and the electromagnetic flowmeter without liner are provided, a layer insulating generation is sprayed
For liner, the technical issues of to solve in the prior art.
Realizing the technical solution of above-mentioned purpose is：A kind of sprayed on material, component include modified isocyanide by mass percentage
Acid esters, 55%-65%；Modified-silicate solution, 35%-45%.
In a preferred embodiment of the present invention, a concentration of 5%- of modified Portland in the modified-silicate solution
35%.
The present invention also provides a kind of electromagnetic flowmeters of no liner, including measure tube body, and inner-wall spraying has an insulating layer,
The insulating layer material therefor is the sprayed on material；Electrode is through to the measurement tube body from the outer wall for measuring tube body
The insulating layer of inner wall.
In a preferred embodiment of the present invention, the thickness of the insulating layer is 10 microns -1000 microns.
In a preferred embodiment of the present invention, when spray applied insulation, spraying conditions are room temperature：15℃-25℃；
Normal pressure：1.01×105Pa。
It is an advantage of the invention that：The sprayed on material of the present invention and the electromagnetic flowmeter without liner, pass through the insulating layer of spraying
Instead of conventional liner, using in sanitary sewage environment or use is in strong acid-base, severe corrosive environment or use is in silt content
In more water body, it can be stably obtained measurement data, longtime running is data stabilization, accurate；It can adapt to various water quality shapes
Condition, and extend service life；Without high temperature and pressure, spraying operation can be carried out at normal temperatures and pressures, it is simple and convenient.
