I. Product introduction:
Product Overview:
TCW non-leakage magnetic drive vortex pump is a new type of pump that uses the magnetic drive of permanent magnet to achieve contact-free transmission of torque, that is, when the motor drives the outer rotor (that is, the outer magnetic steel) assembly to rotate, the magnetic field line passes through the isolation sleeve to drive the inner rotor (that is, the inner magnetic steel) assembly and the impeller to rotate simultaneously, because the medium is closed in the static isolation sleeve, So as to achieve the purpose of no leakage pumping medium, and the main impeller is a thick disc, there are many radial blades on both sides of its outer edge. There is a first class annular flow channel on the pump shell corresponding to the blade, and the whole flow channel is divided into two sides by a pump cover, which are respectively connected with the suction and discharge pipes of the pump. When the inner liquid rotates with the impeller, a certain centrifugal force is generated, which is thrown outward into the annular flow channel in the pump housing, and the flow channel shape is reflow, and then re-enters the other blade channel behind the blade root. Therefore, the movement of the liquid between the blade and the annular flow path is a forward helix for the stationary pump housing; And for the rotating impeller is a backward helix. Vortex pump is named because of this vortex movement of liquid. The liquid can enter between the blades several times in succession to obtain energy until it is discharged from the discharge outlet later. The vortex pump works somewhat like a multistage centrifugal pump, but the vortex pump does not have an energy conversion device like the volute or guide vane of the centrifugal pump. The vortex pump mainly transfers energy to the liquid by multiple continuous work, so it can produce a higher pressure. In the process of energy transfer, due to the multiple impacts of the liquid, the energy loss is large and the efficiency is low, generally 20 to 50%.
Product advantages:
1.TCW non-leakage magnetic drive vortex pump is a new industrial pump developed and designed by our company according to HG/T 2730-2012 (magnetic drive centrifugal chemical process pump), which is fully sealed, non-leakage, pollution-free, small flow, high lift and small volume;
2. The pump body, inner rotor, pump cover, impeller, isolation sleeve and pump shaft and other flow parts can be made of 304, 316, 316L, 904, TA2, HC276 and other materials.
3. The module design and precision casting of the pump body and pump cover should be able to withstand the erosion of high-speed and high-pressure liquid, and can withstand the impact of instantaneous thermal shock, with high cavitation resistance, size ****, smooth flow channel, good interchangeability, to ensure the corrosion resistance and pressure resistance of the pump;
4. Impeller adopts module design and precision casting to ensure reliable torque transmission, its closed structure, flow channel optimization design, high efficiency, low NPSHR value, good interchangeability, to ensure the stability of pump flow and head;
5. The isolation sleeve is designed with 316L, TA2, HC276 and other materials and low vortex insulation sleeve. The isolation sleeve is in a sinusoidal alternating magnetic field, and the eddy current is induced and converted into heat on the section perpendicular to the direction of the magnetic field line. High resistivity, high strength non-metallic materials can be used to make isolation sleeves, which has a very obvious effect on reducing eddy current, eliminating all excess heat and reducing energy consumption; It has high rupture pressure resistance and high safety factor, and completely isolates the pump chamber from the outside world, so that the pump chamber is completely sealed, and no leakage is achieved during the transportation process.
6. The moving ring, shaft sleeve and sliding bearing are made of crystal silicon carbide with high wear resistance and temperature resistance, tungsten carbide and other materials, which have high strength, wear resistance and good resistance to corrosion, effectively ensuring the service life of the pump;
7. The magnetic block uses samarium cobalt 2:17, its magnetic energy product is 28 trillion gaos otes, the limit of tolerable temperature is 350ºC, ******** can avoid demagnetization, making the theoretical service life of the magnetic material up to 20 years;
8. The self-balancing structure of the pump axial force is the use of hydraulic principle, through the fluid pressure difference to automatically balance the axial force, the thrust plate of the rolling bearing is only in the start and stop moment to bear the unbalanced axial force, can achieve almost zero axial force at the working point, greatly improving the stability of the whole machine operation;
9. Double sliding bearing structure, more stable operation, smooth flow of media, lubrication effect of sliding bearing ****; The elastic gasket structure in the shaft sleeve and plain bearing extends the service life of the bearing, reduces the vibration of the pump, and avoids the plain bearing bursting caused by high temperature conditions;
10. No leakage, all sealing points are sealed by closed static seal, driven by magnetic coupling, do not need nitrogen sealing, safe, economic and efficient, **** to solve the medium leakage;
Product Usage: Widely used in petroleum, chemical industry, acid, alkali, smelting, rare earth, pesticides, dyes, medicine, paper making, electroplating, electrolysis, pickling, radio, foil formation, scientific research institutions, national defense industry and other production processes to transport corrosive liquids, especially suitable for flammable, explosive, volatile, toxic, high temperature, strong acid and base, organic capacitive agent and precious liquid transport.
Performance range:
