Segmented pressurization type pollution discharge deep-well pump and operation method thereof

Abstract

The invention discloses a segmented pressurization type pollution discharge deep-well pump and an operation method thereof. The device comprises a first shell, a water inlet is fixedly formed in the upper end of a second shell, the second shell is fixedly arranged at the upper end of the water inlet, a first rotating shaft is movably arranged at the upper end of the interior of the second shell through a bearing, a first impeller is fixedly arranged at the lower end of the first rotating shaft, a first mounting base is fixedly arranged at the lower end in the first shell, a first motor is fixedly arranged at the upper end of the first mounting base, a transmission shaft is movably arranged at the upper end in the first shell through a bearing, and the lower end of the first rotating shaftis fixedly connected with the transmission shaft. The device is good in using effect, the number of the second impellers can be conveniently added at will, the flow speed of liquid pressurized by thedevice at a time can be changed, meanwhile, a third impeller can pressurize the liquid again according to the length of an extension pipe and the length of a discharge pipe, and therefore the device can adapt to a deep mine.

Description

technical field [0001] The invention relates to the field of deep well pumps, in particular to a segmented pressurized sewage deep well pump and an operating method thereof. Background technique [0002] The biggest feature of the deep well pump is that the motor and the pump are integrated. It is a pump that is immersed in the groundwater well to pump and transport water. It is widely used in farmland drainage and irrigation, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Because the motor is submerged into the water at the same time, the structural requirements for the motor are special than those of ordinary motors. The structure of the motor is divided into four types: dry type, semi-dry type, oil-filled type, and wet type. [0003] Existing deep well pumps have the following disadvantages when in use: [0004] 1. The existing deep well pumps can only be pressurized once when they are working, and when the power of the pump bo...

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
