Background
The connecting pipe of the slurry pump inlet and the pipeline is required to be disassembled and assembled when the pump is maintained, a certain adjusting space is required to be reserved between the pump connecting pipe and the pipeline, the original slurry pump inlet adopts an inlet connecting pipe with a fixed size or a rubber elastic joint with a telescopic effect, the pipeline and the pump are strongly connected together through bolts after the pump is maintained by the inlet connecting pipe with the fixed size, and parts such as a pump bracket or a pump shell are deformed or even broken due to the tensile force of the bolts, meanwhile, mechanical sealing failure of the pump is possibly caused, water leakage is caused, and unnecessary loss is caused for users. Although the rubber elastic joint can solve the problem of size variation, the rubber elastic joint does not have wear resistance under mineral separation working conditions such as iron ores, gold ores and the like, and is generally not adopted in the mineral separation industry with serious wear.
Disclosure of Invention
The technical task of the utility model is to provide a pump inlet connecting pipe which realizes the change of the distance between a pump and a pipeline flange through the relative displacement of a pump connecting sleeve and a pipeline connecting sleeve and realizes that a certain adjusting space is arranged between the pump inlet connecting pipe and the pipeline.
The technical scheme adopted for solving the technical problems is as follows: the pipeline connecting sleeve comprises a pipeline connecting sleeve shell and a pipeline lining, and the pipeline lining is arranged in the pipeline connecting sleeve shell.
The pump connecting sleeve shell and the pipeline connecting sleeve shell are respectively metal shells, and the pump connecting lining and the pipeline lining are respectively ceramic linings.
The pump connecting sleeve shell and the pump connecting lining are respectively integrated through filling cementing.
The tail end of the pipeline connecting sleeve shell is arranged in the inner cavity of the pump connecting sleeve shell, the sealing pressing plate is sleeved on the outer circumferential surface of the pipeline connecting sleeve shell and is connected with the pump connecting sleeve shell through the pressing bolt, the right end face of the pump connecting sleeve shell is provided with a groove, and the rubber pad is arranged in the groove.
The cross section of the groove is trapezoidal.
The head ends of the pump connecting sleeve shell and the pipeline connecting sleeve shell are respectively flange structures.
Compared with the prior art, the pump inlet connecting pipe has the following outstanding beneficial effects: the relative distance between the pump connecting sleeve and the pipeline connecting sleeve is adjusted to play a role in compensating the change of the connecting distance between the pump and the pipeline, and the ceramic lining of the lining provides wear resistance, so that the wear resistance and the size compensation requirement of the pump inlet connecting pipe are well met.
