The Long shaft submerged pump is a hydraulic model. The pump shaft is supported by the sliding bearing in the pump cover and the sliding bearing body.
1. Overview of the submerged pump
The long-shaft submerged pump is a hydraulic model. The pump shaft is supported by the sliding bearing in the pump cover and the sliding bearing body. The upper bearing adopts wear-resistant bearings and is lubricated with lithium-based grease. This series of pumps are suitable for conveying various corrosive liquids and clean water, and also suitable for conveying various sewage containing particles or fibers. The temperature range of the conveying medium is -20℃~+120℃, and the working pressure can reach 1.6MPa.
2. Structural characteristics of chemical submersible pumps
Long shaft submerged pump shaft connection structure
Rotor parts can be adjusted axially
The rotor part adopts multi-point support, and the pump runs.
The sliding bearing adopts external lubrication or self-lubrication
When the pump is started, the impeller has been immersed in the medium, so it is easy to start, and there is no problem of exhaust and evacuation
The double-ended volute pump body (above 80mm diameter) is adopted. The rotor components are small in radial force, shaft deflection is small, sliding bearing wear is small, and life is long.
Seen from the motor end, the pump rotates in a clockwise direction.
