Precautions for the operation of split stainless steel magnetic pump

The split stainless steel magnetic pump is composed of
three parts: pump, magnetic transmission and motor.
The key component magnetic actuator is composed of
an external magnetic rotor, an internal magnetic rotor and a non-magnetic isolation sleeve.
When the motor drives the external magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, drive the internal magnetic rotor connected to the impeller to rotate synchronously, realize the contactless transmission of power, and convert the dynamic seal into a static seal
.
Because the pump shaft and internal magnetic rotor are completely enclosed by the pump body and isolation sleeve, the problems of running, running, dripping and leakage are completely solved, and the safety hazards of flammable, explosive, toxic and harmful media leakage through the pump seal in the refining and chemical industry are eliminated, which effectively guarantees the physical and mental health and safety of
employees.
Precautions for the operation of split stainless steel magnetic pump: 1.
Prevent particles from entering (1) Ferromagnetic impurities and particles are not allowed to enter the magnetic transmission and bearing friction pair
.
(2) After transporting the medium that is easy to crystallize or precipitate, it should be washed in time (after stopping the pump, fill the pump cavity with clean water, and discharge it clean after 1min of operation) to ensure the service life
of the sliding bearing.
(3) When transporting media containing solid particles, it should be filtered
at the inlet of the pump flow pipe.
2.
Prevent demagnetization (1) The magnetic torque should not be designed too small
.
(2) It should be operated under the specified temperature conditions, and the temperature of the medium is strictly prohibited
.
A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the ring gap area so that the temperature can alarm or stop
when the temperature exceeds the limit.
3.
Prevent dry friction (1) Idling is strictly prohibited
.
(2) It is strictly forbidden to evacuate
the medium.
(3) In the case of the outlet valve closed, the continuous operation time of the pump shall not exceed 2min to prevent the magnetic actuator from overheating and failing
.
