Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing:
[0022] Such as figure 1 As shown, the fully automatic ground sewage lifting pump unit includes a pump base 17 and a pump shaft 12. The pump shaft 12 is installed on the pump base 17 through an underwater bearing 16. A centrifugal pump and a vacuum pump are installed on the pump shaft 12 at the same time. The vacuum pump is located on the centrifugal pump below.
[0023] The vacuum pump comprises a vacuum pump lower pump body 15, a vacuum pump impeller 14 and a vacuum pump upper pump body 13, the vacuum pump lower pump body 15 is fixed to the vacuum pump upper pump body 13, the vacuum pump lower pump body 15 is installed on the pump base 17, and the vacuum pump impeller 14 is fixed on the pump shaft 12, the corresponding vacuum pump impeller 14 is provided with an eccentric working chamber inside the vacuum pump lower pump body 15, the vacuum pump impeller 14 is located in ...

The invention relates to a full-automatic ground sewage lift pump unit, which belongs to the field of sewage discharging equipment, comprises a pump seat and a pump shaft arranged on the pump seat, and is characterized in that a centrifugal pump and a vacuum pump are simultaneously arranged on the pump shaft. The full-automatic ground sewage lift pump unit can be directly arranged on the ground so as to avoid the phenomena of rust, leakage and the like caused by long time soaking and prolong service life. During installation, due to the fact that the lift pump unit is arranged on the ground, so that installation and maintenance are convenient, installation time is shortened, installation and maintenance cost is reduced, and time and labor are saved. By connecting the centrifugal pump and the vacuum pump through the same pump shaft, under the effect of the vacuum pump, after the pump is opened, vacuum can be fast formed in a pump cavity of the centrifugal pump, so that the aim of automatic pump filling of the centrifugal pump is achieved. The full-automatic ground sewage lift pump unit is simple in structure and small in size and saves time and labor. Due to the fact a centrifugal pump adopts a non-plugging impeller, the phenomenon of impeller plugging caused when sewage medium particles are large is effectively avoided.
Description
technical field [0001] The invention relates to a fully automatic ground sewage lifting pump unit, which belongs to the field of sewage discharge equipment. Background technique [0002] At present, the commonly used sewage pumps are submerged and submersible, and both types of sewage pumps must be installed at the bottom of the sewage tank during use. There are the following defects in use: first, long-term soaking is prone to rust, leakage, and short service life; second, installation and maintenance are inconvenient, time-consuming, and cost-intensive; third, hoisting equipment is required when installing and maintaining sewage pumps. And it is easy to increase the installation and maintenance time. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a fully automatic above-ground sewage lifting pump unit, which has a simple structure, can be directly installed on...
