Novel wastewater pumping device

The novel wastewater pumping device comprises a self-suction tank and a pump main machine, the top of the self-suction tank is communicated with a wastewater pool through an absorption pipe, the bottom of the self-suction tank is communicated with a pump turbine through a pump input pipe, and a turbine shaft in the pump turbine is connected with an output shaft of the pump main machine. The pump main machine is fixed on the base; according to the waste water treatment system, the centrifugal pump (a stopped machine pump can be adopted) is additionally arranged on site, the self-suction tank is installed, operation is normal, the production requirement is met, operation and overhaul are convenient, the risk that an original waste water pump is overhauled in a limited space is avoided, and the maintenance cost is low. 本发明公开一种新型废水泵吸装置，本发明新型废水泵吸装置包括自吸罐和泵主机，所述的自吸罐顶部通过吸收管连通废水池，所述的自吸罐底部通过泵输入管连通泵涡轮，所述的泵涡轮内涡轮轴与泵主机的输出轴连接，所述的泵主机固定在基座上；所述泵涡轮上开设输出管，所述的输出管用于连通酸水站，本发明现场增加一台离心泵（可以采用停用过的机泵），安装自吸罐，运行正常满足生产需要，操作及检修方便，避免了原废水泵的受限
