Problems solved by technology

The propulsion shaft system only requires rotation without telescopic function, so this fixed water sealing device is not suitable for the full-rotation-telescopic dynamic automatic positioning requirements of deep sea offshore work platforms
At the same time, the existing marine shafting water seal friction pairs are generally made of engineering rubber, copper alloy or stainless steel materials, which have poor strength and short wear resistance life, and are not suitable for long maintenance periods and high work reliability of deep sea offshore operation platforms. sexual demands

Abstract

The invention relates to a full revolving-telescopic shafting end surface sealing device used for a deep-sea platform, which is used for a power positioning system of an above-water platform of an ocean engineering to propel shafting water sealing. The sealing device mainly consists of water sealing structures such as a main end surface water sealing friction pair, an adjustable auxiliary end surface water sealing friction pair and a pressure-dividing type auxiliary radial water sealing friction pair and the like. The friction pair adopts solid carbide or uses high-velocity flame spraying technology (or high-temperature overlaying) to melt the solid carbide on a metal material substrate so as to use plunger springs which are distributed axially to compensate automatically the end surface wear of the sealing friction pair. In the process of revolution or axial extension movement of the transmission shaft, each water sealing friction pair have constant sealing state so as to lead the propelling shafting to maintain reliable water sealing performance under the sate of full revolution or extension and the system has high compressive strength and long service life.

Description

technical field [0001] The invention relates to a full-rotation-telescopic shaft end face sealing device for a deep-sea platform, in particular, it is used for the water seal of a full-rotation-telescopic propulsion shaft system of a dynamic positioning system of a deep-sea offshore operation platform, so that the propulsion shaft is reliable. In the water-tight state, the above-water positioning function can be automatically realized. Background technique [0002] Deep sea offshore operation platforms have been performing underwater geological exploration or offshore oil exploitation in remote sea areas for many years, and a reliable underwater positioning method is required. Due to changes in the deep sea depth and various pelagic climates, the underwater undercurrent is surging, and the water surface is rough and the waves are rough, making the water positioning of the water work platform quite difficult. If only relying on the traditional anchor chain positioning, it is ...
