Abstract
The invention relates to a pipeline pump. The pipeline pump comprises a motor, a pump shaft, a pump head and a water body inflow and outflow mechanism. The pump shaft is connected with a motor shaft of the motor through a coupling. The pump head is fixedly connected with the motor through bolts. The lower end of the pump head is connected with the upper end of the water body inflow and outflow mechanism in a sealed manner. A sealing seat is mounted on the pump head and connected with the pump head in a threaded manner. A mechanical seal is arranged at the lower end of the sealing seat. An impeller is mounted at the lower end of the pump shaft. The impeller is located in the working space formed by connecting the pump head and the water body inflow and outflow mechanism. The sealing seat is arranged to be detachable, the split type mechanical seal is used, the mechanical seal can be replaced without disassembling the pump head and the motor, and operation can be achieved through a single person and is extremely convenient. Meanwhile, a traditional integral shaft is replaced with the manner that the pump shaft is connected with the motor shaft through the coupling, and disassembly and assembly of the sealing seat and the mechanical seat are further facilitated.
