捞渣机工作原理及结构介绍(国外英文资料) Working principle and structure introduction of slag dregs introduce Our factory 2, # 3, # 4 furnace slag machine for Clyde the belgae, slag scraper fishing machine produced by our company. The slag scraper fishing machine has easy to transport and on-site installation, easy maintenance, high efficiency of slag, not easy to appear coking jamming phenomenon, etc. It is the first-choice deslag device of modern large thermal power plant. ? The scraping machine mainly consists of tightening device, hydraulic transmission device, circulating water device, slag well system, dregs device, slag bin, electrical control etc. A tightening device ? Inflation device is mainly composed of motor and high pressure gear pump, hydraulic control valve group (including the overflow valve, electromagnetic directional valve, hydraulic control one-way valve, pressure sensor and intelligent digital instrumentation, pressure measuring point), accumulator, oil tank, liquid level controller, filter, oil cylinder and other parts; System to provide the remote transmission signal, such as high pressure alarm signal (100 bar), low pressure alarm signals (45 bar) pressurized and comprehensive fault signal (including filter clogging, tank of liquid level is low, and charging - time is too long, break the chain of); The whole system is controlled by relays, and it is equipped with corresponding lights and selecting switches for operation observation. ? Hydraulic system section ? Fuel tank effective volume: 70 l ? Main pump flow: Q = 4.2 L/min ? Digital instrument pressure control (tentative) : P = 6.0 ~ 9.0 Mpa ? Maximum job pressure: Pmax = 14.0 Mpa ? Motor parameters: AC380V ? P = 1.5 Kw power ? N = 1400 r/min; ? Tension cylinder (quantity 2) : the specification phi 100/70-630 ? Main use mineral hydraulic oil, consult standard viscosity grade (ISO3448:1992) to choose import or domestic major oil companys production of anti-wear hydraulic oil, replace the hydraulic oil require
