The application field of the submerged pump is quite wide, and the diversity of classification standards determines the diversity of the types of the submerged pump. The pump can be simply divided into two categories of traditional submerged pumps (the area 1 outside the tank is explosion-proof, the area 0 inside the tank is not explosion-proof) and novel submerged pumps (the area 1 outside the tank is explosion-proof, the area 0 inside the tank is explosion-proof) according to different explosion-proof grades. Traditional submerged pump is applicable to and carries multiple corrosive materials such as strong acid, alkali, salt, strong oxidizer of certain concentration, and the application of submerged pump is very extensive, and current bearing component can not be fine be connected the pump body with the bearing, and the pump body easily takes place resonance phenomenon in the course of the work moreover to drive the bearing and vibrate together, form resonance, cause the damage to the bearing, for this, we propose a novel major axis submerged pump bearing component of preventing resonating.
