3G horizontal oil transfer magnetic three screw pump
3G horizontal oil transfer magnetic Three Screw Pump applies to deliver clean and non-corrosive medium which has lubricationg property at temperature below 150 C with the viscosity of 3-60 cSt. The pump working pressure range from 0.6 MPa to 6.0 MPa and flow rate range from 0.6 to 300 m3/h.
They are main suited to fuel delivering, hydraulic engineering, shipping engineering, petrochemical and other industry fields.
Magnetic seal / coupling introduction:
Magnetic seal has long service life of the reason is mainly between the seals to maintain a very thin oil film to avoid dry friction between the end face, and to comprehensively consider the effect of the wear and leakage, magnetic seal is the best face lubrication state of boundary lubrication condition.Under normal circumstances, magnetic sealing work under boundary lubrication condition.Friction pair of end face in boundary lubrication condition, relative to the dry friction, boundary friction has lower friction coefficient, can effectively reduce the face wear and prolong service life, end formation fluid lubrication and friction pair will cause leakage.Establish magnetic seal face fluid lubrication is to improve the service life and solve the contradiction in the friction - and wear a effective method.Magnetic seal based friction pair of end face fluid lubrication method is to use appropriate between ring and static ring the gravity and the friction pair of end face of rotary produced under the action of hydrodynamic lubrication film, formation fluid dynamic pressure liquid membrane, and avoid formation fluid lubrication.
In addition, the permanent magnet of magnetic seal ring and static ring together, according to different conditions, different specifications of the permanent magnet, the formation of the appropriate gravity, make the pressure force is formed between the seals is greater than the pressure difference on both sides of the face, thus forming a good sealing performance between the seals.
