Shielded pump selection is impregnated with epoxy resin impregnated graphite sliding bearings, its performance is a good corrosion resistance, high wear resistance and heat resistance, low coefficient of friction. The other in the graphite bearing bore and end have lubrication and cooling groove, so that the media to its lubrication and cooling.

Shield pump purchase tips

Common centrifugal pump drive is through the coupling of the pump impeller shaft and the motor shaft connected to the impeller and the motor together with the rotation work. Shielding pump is also a centrifugal pump, pump impeller part of the motor rotor, along the pump shaft with the motor shaft of the stator. The outer shell for the pump. There is a ring gap of about 0.7mm between the stator and the rotor. When the pump is working, part of the liquid pumped is circulated through the annulus so as to cool the motor.

Therefore, shielded pump compact structure, vibration and noise smaller, high pump efficiency, low energy consumption, no sink. From safety, occupational hygiene and energy savings, the choice of shielded pump for pumping highly corrosive, flammable, explosive or toxic liquids yields satisfactory results.

Vertical shield pump is a kind of special infusion machine with integrated pump. It can be widely used in cold, hot water circulation system, water supply system, and physical and chemical transportation in petroleum, chemical, metallurgy, scientific research institutes, hospitals, schools, hotels, Other media of similar nature to water. Shielding vertical pipe pump is different from the normal horizontal pump where the motor is designed with shielding device, that is, the stator and rotor components are equipped with shielding sleeve to ensure that the stator and rotor cores and windings are not transported medium erosion. Shielding sleeve by the high strength, corrosion resistance, high resistance, non-magnetic stainless steel sheet welded together. Welding and shaping are completed using special equipment and processes, and finally helium leak test weld to ensure that the shielding sleeve is absolutely no leakage.

The other in the shielded motor, the use of impregnated epoxy resin treated graphite sliding bearings, its performance is good corrosion resistance, high wear resistance and heat resistance, low coefficient of friction. The other in the graphite bearing bore and end have lubrication and cooling groove, so that the media to its lubrication and cooling.

Graphite bearing and bearing sleeve constitute the wear to pay, the bearing sleeve of the base body lcr18Ni9Ti stainless steel, nickel-based alloy surface spray welding, which consists of a higher wear-resistant pay. Blue Ocean pump in the motor and the pump overall design, impeller and rotor coaxial running in the medium, there is no shaft seal (any mechanical seal there is wear, leakage problems), so there is no dynamic seal and completely solve the problem of water leakage . As the shielded pump uses a circulating cooling system fitted with a filtration device to ensure that the graphite electromotor always has good lubricity and at the same time cools the motor, thus greatly extending the service life of the motor. In hydraulic design, the impeller using the most advanced level model, precision casting, and rigorous dynamic balance test, high efficiency, stable operation.
