Design and Comparison of Coal Mining Machine Spray Water Circuit Pressurization Scheme
In order to solve the problems of nozzle clogging,dust reduction and poor cooling effect caused by the low pressure of spray water circuit of MG170/410-WD coal miner in 5706 comprehensive mining face,the spray water circuit pressurization scheme is proposed and preferred.Combined with the needs of coal mining machine spraying and from the power source,installation location,economy,structural complexity and reliability,etc.to determine the hydraulic motor drive program applied to the coal mining machine spray water booster,and analyze the structure and application effect of the booster program.After the field application,the water pressure of the spray line of the coal mining machine is kept above 3 MPa,the spray pressure is obviously increased,which shows a significant advantage in enhancing the spraying and cooling effect,and at the same time,the consumption of the cutting teeth of the coal mining machine can be obviously reduced,which shows that the spraying and water booster program used in the field has achieved a better application effect.
