Many people want to know, Mabel environmental protection production of magnetic pumps in the use of what small common sense, that small first take you to understand, what is a magnetic pump, magnetic pump (also known as magnetic drive pump) is mainly composed of a pump head, magnetic drive (magnetic cylinder), motor, base and other parts of the parts.
Magnetic pump magnetic drive consists of outer magnetic rotor, inner magnetic rotor and non-conductive isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation sleeve, and drive the inner magnetic rotor connected with the impeller to rotate synchronously, so as to realise the contactless synchronous transmission of power, and to transform the dynamic sealing structure which is easy to be leaked into the static sealing structure which has zero leakage. Due to the pump shaft, the inner magnetic rotor is completely closed by the pump body and isolation sleeve, thus completely solving the problem of "running, risking, dripping and leaking".
As can be seen from the above, the magnetic pump can be said to be an excellent representative of the pump, solve a lot of industry problems, so that the production goes smoothly, and now I'll take you to learn more about the daily use of some of the precautions of the Mabel magnetic pump.
Pump cavitation is mainly due to the pump inlet pipe resistance, more gas phase of the transport medium, filling the pump is not sufficient, the pump inlet energy head is not enough and other reasons. Cavitation is very harmful to the pump, cavitation occurs when the pump vibrates violently, the balance is seriously damaged, will lead to pump bearings, rotor or impeller damage. This is a common cause of magnetic pump failure.
So that the rotor spindle and the stability of the bearing dry friction, burned bearing. Magnetic pumps are lubricated and cooled by the delivery medium to the sliding bearings, in the absence of open inlet or outlet valves, the sliding bearings due to the absence of delivery medium lubrication and cooling and lead to high temperature and thus damage.
1. Do not allow ferromagnetic impurities, particles into the magnetic actuator and bearing friction vice situation.
2. After conveying the medium that is easy to crystallise or precipitate, it should be flushed in time (fill the pump cavity with water after stopping the pump and discharge it cleanly after running for 1min) in order to guarantee the service life of the sliding bearings.
3. When conveying the medium containing solid particles, it should be filtered at the entrance of the pump flow pipe.
Magnetic pump magnetic coupling is cooled by the pump conveying medium, if the medium has hard particles, it is easy to cause the isolation sleeve scratched or scratched through, sometimes if the maintenance method is not appropriate may also cause damage to the isolation sleeve.
1. Idle rotation is strictly prohibited.
2. Strictly prohibit the media pumping.
3. In the case of the outlet valve is closed, the pump continuous running time shall not exceed 2min, in order to prevent the magnetic actuator overheating and failure.
1. The magnetic torque should not be designed too small.
2. It should be operated under the specified temperature conditions, and it is strictly prohibited for the medium temperature to exceed the standard. Magnetic pump isolation sleeve can be installed on the outer surface of the platinum resistance temperature sensor to detect the temperature rise in the ring gap region, so that the temperature exceeds the limit of the alarm or shutdown.
