Description

Technical Field

[0001] The present application belongs to the technical field of deep well pumps, and specifically relates to a quick-release assembly for a deep well pump. Background Art

[0002] A deep well pump is a type of pump used to extract water from a deep well or groundwater source. It is usually installed underground and uses electricity to work. Deep well pumps are commonly used in a variety of applications such as agricultural irrigation, urban water supply, industrial water or domestic water use.

[0003] The working principle of a deep well pump is to drive the water pump through an electric motor to pump groundwater to the surface. It is usually composed of a pump body, an electric motor, an impeller, a sealing device, and a pump body casing. Deep well pumps are generally designed to be strong and durable, and can cope with long-term work and high water pressure.

[0004] Common deep well pumps include submersible pumps and submersible excavation pumps. Submersible pumps are installed directly below the water source and can be installed in a deep well or well to pump groundwater to the surface through pipes. Submersible excavation pumps, on the other hand, pump water from a deep well or groundwater source by lurking in the water and using a pump in the dredge.

[0005] However, the traditional deep well pump uses a large number of bolts to connect the connection between the power body and the pump body, which has low disassembly efficiency and is not conducive to the maintenance and replacement of the deep well pump. Utility Model Content

[0006] The purpose of the present application is to provide a quick-release assembly for a deep well pump in order to solve the above-mentioned problem that a large number of bolts are used in the connection part between the power body and the pump body of the traditional deep well pump, which has low disassembly efficiency and is not conducive to the maintenance and replacement of the deep well pump.

The positioning groove facilitates the rotation of the main fixing rod and facilitates the connection. After the corresponding installation is completed, the lower connecting ring is inserted into the groove on the upper end of the double-layer positioning ring and then tightened by bolts to fix the power body and the pump body tightly. When the equipment is working, the screen blocks the entry of impurities and forms the connecting parts as a whole to complete the connection. When disassembling, directly rotate the bolts. When the lower connecting ring is deformed and easily detached from the double-layer positioning ring, it can be quickly disassembled. It is simple, fast, stable and effective.

[0015] In a preferred embodiment, the inner surface of the limiting plate is movably connected to a pump shaft, and the inner surface of the pump shaft is movably connected to an impeller.

[0016] By adopting the above technical solution, the rotation of the pump shaft drives the impeller to rotate, and the rotation of the impeller drives the airflow inside the pump body, generating negative pressure, so that the air pressure is pumped from bottom to top.

[0017] In a preferred embodiment, a motor is disposed on the inner surface of the power body, and the outer surface of the motor output end is movably connected to the inner surface of the pump shaft.

[0018] By adopting the above technical solution, the motor provides mechanical power for the equipment, and the corresponding teeth of the motor are engaged in the pump shaft to ensure the rotation of the pump shaft.
