Electromagnetic flow meter scale cleaning method and pored over

Abstract: the electromagnetic flow meter scale big cleaning method to distribute information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Conventional electromagnetic flowmeter test usually contains electrode contact resistance, polarization of electrode voltage, signal cable interference, to determine whether grounding potential and pipeline stray current flow to the five aspects. The following weinan and shunda flowmeter factory technicians for simple for everyone. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flowmeter scale cleaning method and pored over the article details. Conventional electromagnetic flowmeter test usually contains electrode contact resistance, polarization of electrode voltage, signal cable interference, to determine whether grounding potential and pipeline stray current flow to the five aspects. The following flow meter factory technicians for simple introduction for everyone: electrode clean commonly used method has the following kinds: 1. Electrochemical methods: metal electrodes in electrochemical phenomena exist in the electrolyte fluid. According to the principle of electrochemistry, electrode electric field and fluid interface, electrode with fluid interface is electrode/fluid and is caused by the electric double layer. For electrodes and fluid interface electric field of the study found that the substance molecules, atoms, or ions adsorption phenomena in the interface has a rich or poor, and found that most of the inorganic anion surface active substances, as the typical ion adsorption rule, and inorganic cationic surface active is small. Therefore the electrochemical cleaning electrode anion adsorption is only considered. Anion adsorption and there is a close relationship between electrode potential and adsorption mainly in charge potential correction of potential range than zero, the electrode surface with opposite sign charge. On the electrode surface with no charge, when the remaining charge density slightly larger, electrostatic repulsion is greater than the adsorption force, anionic quickly stripping, this is the principle of electrochemical cleaning. 2. Machinery QingChuFa: QingChuFa by installing special mechanical structure on the electrode to achieve clear electrode. There are two forms: one is to use mechanical abrasion. Made with stainless steel scrape with a thin shaft, hollow shaft and adopts mechanical seal in order to prevent the outflow of medium between electrodes, then form the mechanical except the scraper. When rotating thin axis from the outside, close to the tip plane turning, shave their dirt. This in addition to the scraper can be manually, also can use the automatic shave their fine motor drive shaft. 3. Ultrasonic cleaning methods: the ultrasonic generator to produce 45 ~ 65 KHZ ultrasonic wave voltage to the electrode, the ultrasonic energy concentrated on the electrodes in contact with the medium, thus the ability of using ultrasound to shatter bilge, achieve the purpose of cleaning. 4. Electric shock tees: this method USES ac high voltage to the electrodes and the medium between regularly, usually add 30 ~ 100 v. Because the electrodes are attached, the surface contact resistance, almost focused on attachments the applied voltage, high voltage attachments to breakdown, will then be flow away. Total safety, use electric shocks tees must be interruption of flowmeter measurement, signal lines disconnect between sensor and converter, power outage case ac high voltage directly on the sensor signal output terminal for cleaning. Become asymmetric common-mode voltage. Asymmetry of the common-mode voltage becomes differential mode signal, zero offset. Meter factory as a professional research and development type flowmeter production enterprises, over the years, always adhere to the quality and brand, brand for the development of the production concept, perseverance, research, difficult, research and development of new technologies, new products constantly, for the overwhelming majority of customers with reliable quality, comply with the requirements of products, and at the same time, and many enterprises established long-term cooperative relations, set sail together with all my colleagues look forward to working with you. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
