Problems solved by technology

However, the high-pressure rubber hose is a viscoelastic pipeline formed by the rubber rubber layer and the steel wire reinforcement layer, that is, when the high-pressure emulsion passes through the high-pressure rubber hose, the high-pressure rubber hose will undergo viscous deformation and elastic deformation, and the hydraulic energy of the emulsion will be lost, making the pump In the transmission distance from the station exit to the hydraulic equipment of the working face, there is a large pressure drop
In addition, the high-pressure rubber hose has complex dynamic characteristics in the process of high-pressure emulsion transmission, which is difficult to eliminate and control, which seriously affects the response speed and accuracy of hydraulic equipment on the working face
Hard steel pipes for liquid transmission can effectively avoid such problems, but hard steel pipes cannot be bent, making it difficult to adapt to uneven and complex working conditions in underground roadways, and long hard steel pipes are also quite inconvenient to transport

Abstract

The invention relates to a device for conveying liquid by coupling hard steel pipes with visco-elastic pipes, wherein the device is suitable for conveying emulsion under a coal mine. The device comprises the hard steel pipes, the visco-elastic pipes, pipe connectors and buckling nuts, wherein the hard steel pipes are used as a liquid conveying main body, each visco-elastic pipe is connected between the corresponding two adjacent hard steel pipes so that the pipes can be freely bent and transformed, and the pipe connectors and the buckling nuts achieve connection between the hard steel pipes and the visco-elastic pipes. The device is suitable for conveying the high-pressure emulsion of an underground emulsion pump station in a low pressure drop mode, a conveying pipe system integrates the advantages that the hard steel pipes have low pressure drop and the visco-elastic pipes are easily bent, the hard steel pipes and the visco-elastic pipes are combined for use, and the requirement for complex underground working conditions can be met; besides, the hard steel pipes which are not spliced are independent, convenient to transport, and capable of adapting to a narrow working environment of underground space.

Description

technical field [0001] The invention relates to a device for coupling and transmitting liquid with a pipeline, in particular to a device for coupling and transmitting a liquid with a hard steel pipe and a viscoelastic pipeline, which is suitable for underground emulsion transmission in coal mines. technical background [0002] At present, the underground emulsion pumping station system of coal mines transports the emulsion to the coal mining face through a high-pressure hose with viscoelasticity, and then drives the hydraulic equipment on the working face. This is mainly due to the flexible characteristics of the high-pressure rubber hose, which can well adapt to the uneven and complex working conditions of the underground roadway. At the same time, the high-pressure rubber hose can be coiled together and is convenient for transportation, so it has been widely used. However, the high-pressure rubber hose is a viscoelastic pipeline formed by the rubber rubber layer and the st...
