A segmented pressurized sewage deep well pump and its operation method

Abstract

The invention discloses a subsection pressurized sewage discharge deep well pump and its operation method. The device comprises a first casing, a water inlet is fixedly arranged at the upper end of the second casing, and a second water inlet is fixedly arranged at the upper end of the water inlet. The upper end of the second casing is movably provided with a first rotating shaft through a bearing, the lower end of the first rotating shaft is fixedly arranged with a first impeller, and the lower end of the first casing is fixedly arranged with a first mounting seat, so The upper end of the first mounting seat is fixedly provided with a first motor, the inner upper end of the first housing is movably provided with a transmission shaft through a bearing, and the lower end of the first rotating shaft is fixedly connected with the transmission shaft. The present invention has good use effect, and can easily add the number of second impellers arbitrarily, so that the flow rate of the liquid after one pressurization of the device can be changed. Pressurized, so that the unit can be adapted to deeper mines.

Description

technical field [0001] The invention relates to the field of deep well pumps, in particular to a subsection pressurized sewage discharge deep well pump and an operation method thereof. Background technique [0002] The biggest feature of the deep well pump is the integration of the motor and the pump. It is a kind of pump that is immersed in groundwater wells to pump and transport water. It is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Since the electric motor dives into the water at the same time, the structural requirements for the electric motor are more special than those of the general electric motor. The structure of the motor is divided into four types: dry type, semi-dry type, oil-filled type, and wet type. [0003] The existing deep well pumps have the following shortcomings when in use: [0004] 1. When the existing deep well pump is working, it can only be pressurized...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing deep well pumps can only be pressurized once when they are working, and when the power of the pump body is constant when using a deep well, when the liquid flow rate and pressure inside the pipeline do not meet the target requirements, it cannot Select to pressurize again according to the liquid flow rate;

[0005] 2. The number of impellers inside the existing deep well pump is not easy to add or disassemble, so the number of impellers inside the deep well pump cannot be increased or decreased according to the depth of the well used
