Abstract

The invention relates to a pump unit. The pump unit comprises a pump body, a stator shield sleeve, a motor shell and a junction box shell. The stator shield sleeve is arranged above the pump body, theupper portion of the stator shield sleeve is a cylindrical part with an opening in the lower end, and the bottom of the cylindrical part is outwards provided with a flanging part placed on the spigotface of the pump body in the radial direction. The motor shell is in a cylindrical shape with an opening in the lower end, the stator shield sleeve is covered with the motor shell, and the stator shield sleeve is arranged on the upper end face of the pump body through a boss on the outer side of the side wall of the stator shield sleeve. The junction box shell is in a cylindrical shape with an opening in the lower end, the junction box shell covers the motor shell, and the function box shell is connected with the motor shell through bolts. The pump unit is simple and compact in structure, high in space utilization rate, reliable in connection between components and convenient to assemble. The junction box shell wraps the motor shell, so that the motor shell does not need paint spraying, the surface does not need to be subjected to shot blasting treatment, production procedures are reduced, the raw material cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circulating pumps, in particular to a pump unit. Background technique [0002] The operating environment of the circulation pump is complex and the installation space is limited. In the current circulating pumps, the driving motor is arranged in the stator housing, and the axial end of the stator housing is provided with a junction box, and the electronic components of the driving motor are arranged in the junction box, so that the pump components can achieve different functions in different embodiments. . This kind of pump unit has a large volume and is not suitable for an environment with limited installation space, and the structure of the pump unit is complicated, which makes the assembly process complicated and the assembly time is long. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a pump unit with simple and co...
