Application Fields of Magnetic -driving Pumps:
With the more importance of the global environmental protection and with enforcement environmental protection regulations, due to non-leakage, low noise, static seal, supplying extraordinary conveying requirements of inflammable, explosive and poisonous fluids, magnetic -driving pumps are rewarded as environmental protection high–tech products. In the recent year, the development speed of magnetic -driving pumps is very fast. Pumps with mechanical seals are replaced with magnetic-driving pumps progressively. Magnetic-driving pumps have widely applied to oil fields, refinery, petrochemical, chemical, fertilizer, power Station, metallurgy, food processing and pharmaceutical, etc. Its application is lo convey clean inflammable, explosive, severely poisonous, precious liquids free from particles and other liquids that permit no seal pollution, unsuitable to convey the liquids including ferromagnetism substance.
The Principle of Magnetic -driving Pumps:
Magnetic-driving parts are composed of magnetic in-rotor and magnetic out–rotor; Magnetic in-rotor and medium are cut off from magnetic out-rotor by a shroud. Magnetic out-rotor is driven by motor; when magnetic out-rotor runs, magnetic in-rotor begin to run because of magnetic coupling characteristics. So pumps are driven by the way of non -contact transmission of moments.
Magnetic-driving pumps are different from other pumps with mechanic seals by replacing dynamic seals with static seals. Solve absolutely leakage problem during pumps running.
The structure of magnetic-driving pumps is simple. The design of special lubricant and coolant circuit guarantees satisfactory lubrication and cool-off. No cool-off, swill, quick-cool pipe system that pumps with mechanical seals require. Rated suction pressure can reach to 30MPa; it is difficult for pumps with mechanical seals to do.
Running slick and stably, low noise, non-leakage, cleanness and safety, magnetic-driving pumps are rewarded as real environmental protection products in industries
