As environmental protection has received more and more global attention and corresponding environmental regulations have been promulgated and implemented, magnetic drive pumps have been praised for their no leakage, static sealing and low noise, which solve the pumping problems of fugitive substances in industrial systems. It is an environmentally friendly high-tech product.
1. Prevent particles from entering
Ferromagnetic impurities and particles are not allowed to enter the magnetic transmission and bearing friction pairs. ◉ Flush in time after transporting media that is easy to crystallize or precipitate (fill clean water into the pump chamber after stopping the pump, and drain it after running for 1 minute) to ensure the service life of the sliding bearing. ◉ When transporting media containing solid particles, filtering should be performed at the inlet of the pump flow pipe.
2. Prevent demagnetization◉ The magnetic torque cannot be designed too small. ◉ It should be operated under specified temperature conditions, and it is strictly forbidden for the medium temperature to exceed the standard. A platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve of the magnetic pump to detect the temperature rise in the annulus area, so as to alarm or shut down when the temperature exceeds the limit.
3. Prevent dry friction◉ The magnetic torque cannot be designed too small. ◉ Evacuation of media is strictly prohibited. ◉ When the outlet valve is closed, the continuous operation time of the pump shall not exceed 2 minutes to prevent the magnetic actuator from overheating and failure.
Working principle of magnetic drive pump: The transmission part of the magnetic drive pump is composed of inner and outer magnetic rotors; the spacer sleeve isolates the inner magnetic rotor and the medium from the outer magnetic rotor; the outer magnetic rotor is driven by the motor , when rotating, the magnetic fusion characteristics are used to drive the internal magnetic rotor to rotate, completing non-contact torque transmission, thereby achieving the purpose of driving the pump. The spacer sleeve completely isolates the inner magnetic rotor and medium from the external magnetic rotor. Therefore, the magnetic drive pump is different from other mechanical seal pumps in that it has no dynamic seal, only static seal, which fundamentally solves the problems of running, popping, dripping and leaking of the mechanical seal pump in the process, and achieves no leakage at all. magnetic pump , simple and compact structure. Using a unique lubrication and cooling circuit, part of the process liquid self-lubricates and cools the transmission components, eliminating the need for cooling and flushing of the mechanical seal pump. , quenching and other complex pipeline systems. The maximum design inlet pressure can reach 30MPa, which is difficult for mechanical seal pumps to achieve. Magnetic pump, safe and reliable operation, low noise, no leakage, clean and safe process site , is a truly industrial environmentally friendly product.
Magnetic drive pump application areas:
As environmental protection has received more and more global attention and corresponding environmental regulations have been promulgated and implemented, magnetic drive pumps have solved the problem of pumping fugitive substances in industrial systems due to their leak-free, static sealing and low noise. , thus known as environmentally friendly high-tech products.
In recent years, magnetic drive pumps have developed strongly and are gradually replacing mechanical seal pumps with the same performance. They have been widely used in oil fields, oil refining, petrochemicals, chemicals, fertilizers, nuclear power, and metallurgy. In industrial systems such as , food and pharmaceuticals, flammable, explosive and toxic media that do not contain solid particles and media that are not allowed to be sealed and contaminated are transported. Not suitable for transporting media containing ferromagnetic substances.
