Purpose This paper aims to focus on the high-speed rotary lip seal in aircraft engines, combining its service parameters, own structure and application conditions, study influence of different eccentric forms, eccentricity, rotational speed other factors performance seal. Design/methodology/approach A numerical simulation model for seals has been developed based theory elastic hydrodynamic lubrication. comprehensively considers coupling multiple physical fields, including interface...
The main shaft seal of offshore wind power equipment is one the key components systems. However, wear issues between seals and caused by intrusion particulate matter in environment have become a factor affecting service life equipment. To improve surface performance shaft, this study used laser cladding technology to prepare an Fe55 coating on QT-500 components. Through experiments HNBR pairs with under different load conditions, thoroughly investigated impact frictional coefficients,...
Abstract Metal entangled structure is a porous metal damping material wound by spiral springs and formed cold stamping. Its interior consists of interlocking springs. To further make the have characteristics high stiffness at same time, high‐performance structure‐silicone rubber composite was designed. The viscoelastic properties, mechanical stability, deformation behavior, damage mechanism were investigated relaxation test, cyclic loading different rate respectively. effects preparation...
The in-pipe robot is the most commonly used technique in offshore pipelines. use of rubber sealing discs important for robots to ensure that are moved by fluid pressures inside This paper focuses on measuring and modeling wax–oil gel-breaking process at soft frictional area between pipe wall. In this study, a detailed characterization gel-scraping situ probing portable microscopy performed. Two contributions made study. First, direct observation deposition breaking employed detect minute...
Water-based lubrication, due to the poor film-forming ability of water, faces challenges in achieving effective lubrication for titanium alloys. This study systematically investigates frictional performance phosphorus-based extreme pressure (EP) additives and self-emulsifying esters (SEE) on surface alloy (TB6) under different pressures temperatures. The core lubricant consists SEE with nonylphenol polyoxyethylene ether phosphate ester (NPEP), oleyl (POEP), alcohol (AEP). Results show that...
For this study, E690 steel claddings with different contents of TiC were prepared by laser cladding for revealing effects on microstructure, mechanical properties, and wear behavior the cladded steel. The microstructure properties alloys observed measured. resistance was tested using a ball-on-disc tribometer. experimental results showed that refined grain alloy obviously. However, excessive could lead to network-like distribution submicro particles in claddings. microhardness 1% increased...
To improve the wear resistance and anticorrosion property of duplex stainless steel (DSS), surface treatment combining high-energy shot-peening (HESP) electrochemical nitriding was applied to DSS. The strong nitride peak detected through X-ray photoelectron spectroscopy indicated that HESP pretreatment accelerated process. treatments improved microhardness DSS from 242 HV(100g) 450 considerably enhanced. Electrochemical tests revealed passivation ability layer in borate buffer 3.5 wt-% NaCl...
