Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer suitable for deep wells. Background Art

[0002] A deep well pump is a pressurizing device that pumps water from a deep well to the surface. Due to the large depth of the deep well and the low groundwater level, the deep well pump needs to be able to deliver a sufficiently large torque to the impeller to raise the water in the deep well to a sufficiently large head. When the viscosity of the well fluid is relatively high, the deep well pump must use a reducer for power input.

[0003] When the existing reducer is lowered into a deep well, the reducer is prone to shaking and colliding with the well wall, thereby causing damage to the reducer. Therefore, the utility model provides a reducer suitable for deep wells to solve the above-mentioned problems. Utility Model Content
