Problems solved by technology

[0002] Traditional centrifugal pumps use ordinary Y-shaped motors for power output. The motors are air-cooled and must exchange heat with the outside air, so they cannot be integrated with a closed external casing. Therefore, the operating environment is strictly restricted. Dry, otherwise it will cause the motor to burn or even cause casualties
[0003] Traditional submersible motors are cooled by water cooling, but they can only be cooled in a water environment, not on land
[0004] Traditional centrifugal pumps cannot be used in various environments due to the constraints of water intake location, weather, rainfall and floods.

Embodiment Construction

[0014] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] The invention is an amphibious vertical centrifugal pump unit. The centrifugal pump adopts a new submersible motor as the power equipment of the centrifugal pump. The cooling method is changed from air cooling to water cooling. Amphibious operations can replace IS and S-type water pumps in engineering applications, and are widely used in pumping stations such as agriculture, industry, water supply, and drainage. It has unique advantages in terms of environment, and it can also greatly reduce civil engineering investment and construction difficulty, reduce operation and maintenance costs, and exert significant comprehensive benefits.

Abstract

The invention provides an amphibious vertical centrifugal pump unit. The centrifugal pump (1) is connected with a heat exchange housing (8) and a submersible motor (9) through a connecting casting (4), and the heat exchange housing (8) and the motor Between (9) is a heat exchange chamber (7), the cooling circulation waterway beginning (11) on the centrifugal pump (1) is connected with the water inlet pipe (10) of the cooling circulation waterway, the water inlet pipe (10), the heat exchange chamber (7), the cooling circulation water return pipe (5) and the cooling circulation water end (3) are connected in sequence. The submersible motor (9) drives the centrifugal pump (1) to work, most of the water is conveyed along the main pipeline of the centrifugal pump (1), and a small part of the water is sent to the beginning of the cooling circulation waterway (11), and the water flows through the water inlet pipe (10), The heat exchange chamber (7) and the return pipe (5) then enter the end of the cooling circulation waterway (3) and merge with the main pipe.

Description

technical field [0001] The invention relates to the centrifugal pump unit technology, in particular to an amphibious vertical centrifugal pump unit. Background technique [0002] Traditional centrifugal pumps use ordinary Y-shaped motors for power output. The motors are air-cooled and must exchange heat with the outside air, so they cannot be integrated with a closed external casing. Therefore, the operating environment is strictly restricted. Dry, otherwise it will cause the motor to burn or even cause casualties. [0003] Traditional submersible motors are cooled by water cooling, but they can only be cooled in a water environment, not on land. [0004] Traditional centrifugal pumps cannot be used in a variety of environments due to the location of water intake, weather, rainfall and floods. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide an amphibious vertical centrifugal pump unit, which uses water cooling ...
