Problems solved by technology

[0002] As a kind of water pumping equipment, the water pump is used to pump water from a low place to a high place. The existing deep water pumps are generally used in connection with the motor and the water pump. The top of the large submersible pump is generally connected with a pipe of more than several hundred meters. The water pressure is very high, and the working intensity of the water pump is very high. The traditional motor and the water pump are connected by a single shaft, which is subject to a large force, the length of the single shaft is too large, easy to bend, not durable, and the service life of the water pump is low.

Embodiment Construction

[0017] The present invention will now be further described in detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only schematically illustrate the basic structure of the present invention, and therefore only show the configurations related to the present invention.

[0018] like Figure 1-3 As shown, the biaxial water pump is composed of a driving part 1 and a pumping part 2. The driving part 1 includes a driving motor 11 and an upper cover 12 set outside the driving motor 11. The pumping part 2 includes a water pump 21 and a water pump 21. The outer lower cover 22, the driving motor 11 and the water pump 21 are connected through a double-joint shaft 3, and the motor drives the water pump 21 to work, wherein the double-joint shaft 3 includes an upper coupling shaft 31 and a lower coupling shaft 32, and the upper coupling shaft 31 It is the output shaft of the motor. The lower end of the upper coupling shaft ...

Abstract

The invention relates to a two-shaft water pump, belongs to the technical field of water pumps and particularly relates to a water pump of which the motor and the water suction pump are connected through a two-section shaft. The invention aims at providing the water pump of which the coupling shafts cannot be easily bent and the service life is long. The adopted technical scheme is that the two-shaft water pump consists of a drive part and a water suction part; the drive part comprises the drive motor and an upper cover body covering the drive motor; the water suction part comprises the water suction pump and a lower cover body covering the water suction pump; the drive motor and the water suction pump are connected through the two-section shaft; the water suction pump is driven to work by the motor, wherein the two-section shaft comprises an upper coupling shaft and a lower coupling shaft; the upper coupling shaft is an output shaft of the motor; after passing through a bearing block, a motor seal cover and a connecting piece in sequence, the lower end of the upper coupling shaft is connected with the upper end of the lower coupling shaft through a shaft coupling; after passing through a water outlet connecting piece and a bearing seal cover in sequence, the lower end of the lower coupling shaft is connected with a main shaft of the water suction pump.

Description

technical field [0001] The double-shaft water pump of the invention belongs to the technical field of water pumps, and in particular relates to a water pump in which a motor and a water pump are connected through a double-jointed shaft. Background technique [0002] As a kind of water pumping equipment, the water pump is used to pump water from a low place to a high place. The existing deep water pumps are generally used in connection with the motor and the water pump. The top of the large submersible pump is generally connected with a pipe of more than several hundred meters. The water pressure is very high, and the working intensity of the water pump is very high. The traditional motor and the water pump are connected by a single shaft, which bears a lot of force, the length of the single shaft is too large, easy to bend, not durable, and the service life of the water pump is low. Contents of the invention [0003] The object of the present invention is to provide a wate...
