Embodiment Construction

[0019] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 ~ Figure 4 The pipeline pump shown includes a motor 1 , a pump shaft 2 , a pump head 3 and a mechanism 4 for entering and exiting a water body. The pump shaft 2 is connected to the motor shaft 5 of the motor 1 through a coupling 6 , and a protective plate 17 is arranged outside the coupling 6 . By setting the protective plate 17, the shaft coupling 6, the pump shaft 2 and the motor shaft 5 are effectively protected to ensure that they are not easily damaged during use. The upper end of the pump head 3 is fixedly connected with the motor 1 by screws, and the lower end of the pump head 3 is sealed and connected with the upper end of the water inlet and outlet mechanism 4 . A seal seat 7 is installed on the pump head 3, and the lower end of the side surface of the seal seat 7 is provided with an external thre...

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.

Description

technical field [0001] The present invention relates to pipeline pumps. Background technique [0002] Now the pump heads of pipeline pumps on the market are basically built-in mechanical seals. The seal seat and the pump head are integrally formed and cannot be disassembled. The mechanical seal is easily damaged as a vulnerable part. To replace the damaged mechanical seal, the pump head and the pump head must be removed The motor, if the motor is too large, it needs the cooperation of multiple people to complete the replacement, which is very troublesome. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a pipeline pump, which can be operated by a single person without disassembling the pump head and motor by setting the seal seat as a detachable type and using a split mechanical seal. ,Very convenient. [0004] In order to achieve the above object, the present invention adopts the follow...
