Magnetic pump is a new type of pump the working principle of magnetic coupling to transmit torque without contact, when the motor drives the outer magnetic rotor, the magnetic pump is driven by the magnetic field of the magnetic rotor and impeller synchronous rotation, so as to achieve the purpose of pumping liquid, because the liquid is enclosed in static Isolation Kit so, the magnetic pump is a sealed, leak free pump. Magnetic pump to cancel the mechanical seal, completely eliminating the mechanical seal of the inevitable run, run, drip, drip, leakage of the ills, magnetic pump is the best choice for no leakage factory. Because of the magnetic pipe pump of the over - current components of stainless steel, engineering plastic to manufacture, so as to achieve the purpose of corrosion resistance. Magnetic coupling and pump body of the magnetic pump is one, so the structure is compact, easy maintenance, safety and energy saving. The magnetic coupling of the magnetic pump can be the function of overload protection of the transmission motor.
Magnetic pipe pump with its full seal, no leakage, corrosion characteristics, magnetic pump widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and printing photos, defense and other departments for pumping flammable, explosive, toxic and expensive liquid, magnetic pipeline pump is created without leakage, no pollution plant of civilization civilization, the ideal pump factory.
Magnetic pump operating conditions of magnetic pump transmission medium density is not greater than 1300kg/m3, the viscosity is not greater than 30 x 10-6m3/S of the non ferrous and fiber liquid. Magnetic pipe pump rated temperature on the pump body is made of metal material or F46 lining, the maximum working temperature of 80 DEG C, the rated pressure is 1.6MPa; the use of magnetic pump pipeline temperature less than 350 DEG C; the magnetic pipe pump body is non metal material, the highest temperature does not exceed 60 degrees, the rated pressure is 0.6MPa.
For the transmission medium density is greater than 1600kg/m3 of the liquid, magnetic coupling need to be designed. Magnetic pipe pump bearing is carried out by the medium of lubrication cooling, drum magnetic pump is strictly prohibited no-load operation.
Five main points of using magnetic pump:
1, test: check whether there is any loose connections; the rotor rotation circle dynamic coupling disc by hand, look at the unit rotation is flexible, whether there is noise and weight unevenness feeling, to determine whether the foreign body or the pump shaft is bent, the seal is not correct; check the seal cavity No. 20 clean lubricating oil is filled with 1/2 cavity space; magnetic pump unit surface is clean; the steering unit no-load test.
2, manual start: irrigation pump (the first time), a little open outlet valve, start the motor, the pressure rise and confirm to the centrifugal pump set to run smoothly when the valve to the working conditions of the valve to the working conditions.
3, running check: Pump in the normal operation of the power frequency (Bian Pin), should be regularly checked and recorded the pump set of current meter, voltmeter, import and export vacuum gauge, pressure gauge and flow meter reading. Unit of vibration, noise, Wen Sheng, etc.. The seal at the fuel leakage should not be obvious.
4, normal parking: close the discharge valve, so that the pump light load, the motor stopped.
5, emergency stop status:
A, pump motor operating current meter indicator (excessive or too large or small); magnetic pump system to send an abnormal sound.
B, vacuum pump inlet pressure gauge, pressure gauge instructions export abnormal magnetic pipe vibration pump body and a different sound of a larger, serious decline in performance.
C, pump motor odor, seal oil leakage of air, bearing temperature exceeding 75 DEG C etc..
Magnetic pump can be widely used in chemical, pharmaceutical, petroleum, unit of electroplating, food, film, photographic development research institutions, national defense industry pumping acid, lye and oil, rare valuable liquid, venom, volatile liquid, and circulating water equipment, filter. Magnetic pump especially easy to leakage, flammable and explosive liquid pumping, selection of the magnetic pump is more ideal.
