Stainless steel Shield Motor Pump can be used to transport flammable and explosive media, or used in explosive dangerous places. The pump body is required to use explosion-proof materials, such as aluminum alloy, stainless steel and other materials. It has simple structure, stable performance, high speed, small size, light weight, high efficiency, large flow and easy operation
The SS canned motor pump uses the same shaft to fix the rotor of the motor and the impeller of the plunger metering pump, and then shield the group of rotors with a shielding sleeve. The stator of the motor surrounds the shielding sleeve, which is made of metal, so the power can be transmitted to the rotor through the magnetic field. The entire rotor runs in the pumped liquid. The end of the shield is statically sealed by flange or welded structure. The shielding sleeve is actually a pressure vessel. The inner surface of the stator and the outer surface of the rotor are equipped with a stator shielding sleeve and a rotor shielding sleeve made of a corrosion-resistant metal sheet. The respective end faces are welded with corrosion-resistant metal sheets to separate them from the conveyed liquid, so that the stator winding core and the rotor core are not corroded. In addition to the shielding sleeve, another component is the circulation pipe, which uses pumped liquid to lubricate and cool the bearing and sometimes also cool the motor. The axial force balance method of the canned motor pump usually adopts an automatic thrust balance device, and sometimes a radial blade on the back of the impeller is also used, that is, a back impeller thrust balance mechanism.
Briefly describe the product characteristics of the flameproof canned motor pump: 1. The canned motor pump is fully enclosed. There is no dynamic seal in structure, only static seal, so it can be completely leak-free, especially suitable for transporting flammable, explosive, precious liquid and toxic, corrosive and radioactive liquid. 2. It has the advantages of advanced design, high efficiency and energy saving, and zero leakage, which successfully solves the problem of running and breaking in fluid transportation. drop. Problems such as leakage have become irreplaceable products in environmental protection projects. This pump is widely used in petroleum, chemical, pharmaceutical, refrigeration, biodiesel and other fields, especially for conveying flammable, explosive, volatile, corrosive, precious and other liquids. 3. The Shield Motor Pump has a compact structure, the pump and the motor are integrated, and there is no need to align the center for disassembly and assembly. And the daily maintenance workload is small, and the maintenance cost is low 4. Smooth operation, low noise, no need to add lubricating oil. Because there is no rolling bearing electric motor fan, no lubricating oil is needed, and the noise is low. 5. Wide application range. It can meet the requirements for various working conditions such as high temperature, high pressure, low temperature and high melting point.
