Magnetic Shaft Coupling:
Attractive couplings are shaft couplings that utilization an attractive field rather than an actual mechanical association with communicate force starting with one shaft then onto the next. They are non-contact and use fascination and repugnance of the attractive shafts to send rotational power.
Process:
Because a static, physical barrier may be created between the two shafts to isolate the fluid from the motor running in air, magnetic shaft couplings are most commonly utilized for liquid pumps and propeller systems. Magnetic shaft coupling eliminate the need for shaft seals, which wear out and break over time as two surfaces slide against each other. When physical shaft couplings are employed, magnetic couplings are also used for ease of maintenance on systems that generally demand precision alignment, because they allow for more off axis error between the motor and driven shaft.
Power can be transferred to centrifugal pumps using a magnetic connection. It consists of a primary part that is rigidly attached to the motor shaft and a secondary part that is mounted alongside the impeller on a shaft. Permanent magnets are used in both the primary and secondary sections.
With the discretionary plate coupling, the magnets face each other pivotally, permitting forces to be sent through level dividers. The air hole can be acclimated to change the communicable force.
Types:
While all attractive couplings utilize similar attractive properties and fundamental mechanical powers, there are two sorts that vary by plan.
Circle type couplings highlighting two eye to eye plate parts installed with a progression of magnets where force is moved across the hole from one plate to the next.
Simultaneous sort couplings, for example, super durable dexter magnets couplings, coaxial couplings and rotor couplings where an inner rotor is settled within an outer rotor and extremely durable magnets move force from one rotor to the next.
Notwithstanding the two principle types, attractive couplings incorporate round, capricious, twisting and nonlinear plans. These attractive coupling options help in the utilization of force and vibration, explicitly utilized in applications for science, science, quantum mechanics, and water power.
How much force produced by this cycle is controlled by factors, for example,
Working temperature
Climate in which handling happens
Attractive polarization
Number of post sets
Aspects of post sets, including hole, breadth and tallness
Relative precise offset of the sets
Shift of the sets
Contingent upon the arrangement of the magnets and plates or rotors, the attractive polarization is spiral, digressive or hub. Force is then moved to at least one moving parts.
Features of magnetic couplings
Attractive couplings are viewed as better than customary mechanical couplings in more than one way.
The absence of contact with moving parts
Lessens contact
Delivers less hotness
Utilizes power delivered
Brings about less mileage
Creates no commotion
Takes out the requirement for grease
Likewise, gadgets utilizing attractive couplings are more practical than mechanical couplings when situated in regions with restricted admittance. Attractive couplings are a famous decision for testing purposes and transitory establishment.
Applications: Attractive couplings are exceptionally productive and successful for a considerable length of time ground applications including:
Advanced mechanics
Synthetic designing
Clinical instruments
Machine establishment
Food handling
Revolving machines

They provide output signals in direct proportion to changes in liquid level.Simple, modular design and proven magnetic coupling make Modulevel controls versatile, highly stable, vibration resistant and adaptable to extremes of temperature and pressure.Principle OF Pneumatic Modulevel Liquid level control The key elements of the Pneumatic Modulevel Liquid level control are the magnetic coupling, which allows the controller to be mechanically isolated from the sealed sensing unit; the range spring, which dampens the action of the displacer, and the control head, which provides a modulated pneumatic signal in direct proportion to the input from the vertical motion of the displacer.As the liquid level in the vessel increases or decreases, the buoyant displacer rises or falls.This motion, dampened by the action of the range spring to prevent response to the rapid fluctuations of turbulence, is mechanically coupled to an attractor ball, within an enclosed tube.
A magnet encircling the tube follows the attractor ball, transferring the motion to a rotating cam,which in turn operates a flapper against a nozzle which increases or decreases the pressure within the pneumatic relay.
The output pressure signal can be used in a variety of ways to operate a control valve or signal to alarms, indicators, process controls or other devices.
With optional integral control, the pilot nozzle proportional signal is conditioned through an additional metering valve system, which will eliminate offset from the desired control point.Features of Pneumatic Modulevel Liquid level control - Standard models handle service temperatures from -100°C to +370°C (-150°F to +700°F) and pressure to 294 bar (4265 PSIG).
- Stable output signal is unaffected by surface turbulence.Prevents control valve “hunting” and extends valve life.
- Accurate output signal provided over a wide specific gravity range.
