Magnetic pump is widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, national defense and other departments for pumping flammable, explosive, toxic and precious liquids due to its fully sealed, leak-free and corrosion-resistant characteristics. It is an ideal pump for creating civilized workshops and civilized factories without leakage and pollution.
Working condition
The density of the medium transported by the magnetic pump is not more than 1300kg / m3, and the viscosity is not more than 30 × 10-6m3 / S. The liquid does not contain ferromagnetic and fiber. The rated temperature of the conventional magnetic pump is a metal material or F46 lining for the pump body. The maximum operating temperature is 80 ℃ and the rated pressure is 1.6MPa; the operating temperature of the high temperature magnetic pump is ≤350 ℃; for the pump body is non-metallic material, the maximum temperature is not Over 60 ℃, the rated pressure is 0.6MPa.
For the liquid with a density of more than 1600kg / m3, the magnetic coupling needs to be designed separately.
The bearing of the magnetic pump is lubricated and cooled by the conveyed medium. The drum magnetic pump is strictly forbidden to run without load.
Magnetic drive centrifugal pump (referred to as magnetic pump for short) is a new type of pump that uses modern magnetic mechanics principles and uses permanent magnet magnetic transmission to achieve non-contact transmission of torque. That is, when the motor drives the external rotor (ie, external magnetic steel) assembly to rotate Through the action of the magnetic field, the magnetic force lines pass through the isolation sleeve to drive the inner rotor (ie, the inner magnetic steel) assembly and the impeller to rotate synchronously. Because the medium is enclosed in the static isolation sleeve, the purpose of pumping the medium without leakage is achieved, and the mechanical transmission is completely solved The shaft seal of the pump is leaking, and the new industrial pump is completely sealed, leak-free and pollution-free.
Magnetic pump is an ideal pump to eliminate running, running, dripping, and leakage in the chemical process, eliminate environmental pollution, create "leak-free workshop" and "leak-free factory", and realize safe and civilized production. Widely used in the production process of petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other enterprises to transport corrosive liquids without iron filing impurities, especially suitable for flammable, explosive, volatile, toxic and precious liquids delivery.
In the field of petrochemical industry, more and more manufacturers require a leak-free process environment for the media they transport. In some special occasions, such as transporting hot oil or granular media (such as sewage treatment), and chemical production In the process, it is more urgent to choose the ideal leak-free pump type. Based on the production of CQ magnetic pumps, our company has introduced new technologies at home and abroad, and successfully developed MT-HTP series magnetic transmission high temperature chemical process pumps, MT-MSP series magnetic transmission high temperature multistage pumps and those with suspension separators. The magnetic pump product series solves the technical problems of high temperature (350 ℃) and granular media that conventional magnetic pumps have not solved, and can directly replace the mechanically driven IH type chemical pumps. MT series magnetic pumps have passed the long-term production continuous operation test, and users can be confident that they have chosen the safest and most reliable pump type.
Transmission principle
Magnetic pump is a new type of pump that uses the working principle of magnetic coupling to transmit torque without contact. When the motor drives the external magnetic rotor to rotate, the internal magnetic rotor and the impeller are rotated synchronously by the action of the magnetic field, thereby achieving the pumping of liquid Purpose, because the liquid is enclosed in a static isolation sleeve, it is a completely sealed, leak-free pump type.
Pump characteristics
The mechanical seal of the pump is canceled, and the unavoidable disadvantages of running, running, dripping, and leakage of the mechanical seal centrifugal pump are completely eliminated, and it is the best choice for a leak-free factory.
Because the pump's over-flow parts are made of stainless steel and engineering plastics, the purpose of corrosion resistance is achieved.
The magnetic coupling of the pump and the pump body are integrated into one body, so the structure is compact, the maintenance is convenient, and it is safe and energy-saving.
The magnetic coupling of the pump can protect the transmission motor from overload.
