The difference between the shielding pump and application field of magnetic pump

shielding pump is a kind of no seal pump, shielding pump and drive motor are sealed by pumping in a medium full of pressure container, the pressure vessel is only static seal, and is provided by a group of wires to a rotating magnetic field and drive the rotor. This structure is cancelled traditional of rotation of the centrifugal pump has a sealing device, it can be completely without leakage. Application field of shielding pump

This structure is cancelled traditional of rotation of the centrifugal pump has a sealing device, it can be completely without leakage. The application areas of shielding pump

a, in the aspect of civil:
, ground source heat pump air-conditioning circulating water system;
and lithium bromide air conditioning air conditioning pump unit, transformer oil pump, engine pump, etc. ;
and heating circulating water system;
and fire fighting water pressurization system;
, tap water pressurization system.
2, in the industrial and military space:
, chemical and pharmaceutical industries with poisonous and harmful liquid delivery;
, space with former rocket fuel filling;
by the level of nuclear shielding pumps, nuclear power plants.
shielding and magnetic pump aspects in common:
, belong to the vane type centrifugal pump.
, no seal, but have no leakage.
shield pump magnetic pump and difference:
is straight association-like, shielding pump motor, the motor with a shielding set between the stator and rotor, motor equipped with circulation cooling structure, cooling motor, the purpose of lubrication bearings.
, magnetic pump, the motor through magnetic coupling and the outer magnetic steel together, within the impeller and magnet steel together. Within the outer magnetic steel and is equipped with fully sealed spacer between magnetic steel, separated from the inner and outer magnetic steel completely, make the magnetic steel in medium, the rotating shaft of the motor driven directly by between magnetic poles of the suction impeller synchronous rotation.
