摘要
煤炭全自动制样系统是近年来煤炭检测领域应用推广的智能化新产品,目前在行业或全国层面还未制定其产品标准。为了满足研发人员、制造商、使用者在设计制造、交货验收、日常监管等方面开展质量管理和质量评价的需要,根据可靠性和全面质量管理原理,结合相关国家标准和行业标准,经过广泛科学调查,从产品可用性、适用性、使用性能、环保与职业卫生等4个维度全面系统研究煤炭全自动制样系统的技术要求,提出了产品可靠度、维修度、保障度、可用度等16项主要质量指标参数与相应要求及其检测方法,以期作为产品质量标准的制定依据以及制造商、使用者、第三方机构进行产品质量的评价依据。其中,可用性指标主要包括产品可靠性、维修性和保障性、可用性,适用性指标涵括煤的标称最大粒度、煤的类别与水分、额定工作能力,使用性能指标采用整系统煤样的损失率、粉碎机细粉质量损失率、整系统制样精密度、水分试样制备单元的全水分损失率、干燥单元的挥发分偏倚和整系统灰分偏倚6个性能指标来衡量,而环保与职业卫生指标由颗粒物排放、制样室粉尘、制样室噪声构成。同时建议采用可用度(A)指标衡量制造方的设计、制造和服务综合水平。
Automatic coal sample preparation system is a new intelligent product applied in field of coal testing in recent years,but there is no industry or national standard for it currently.To meet the quality control and quality assessment requirements of researchers,manufacturers and users during the design and manufacture,delivery and acceptance,daily supervision and so on,according to the principle of reliability and total quality management,combining with national standards and industry standard,through the extensive scientific investigation,from aspects such as product availability,product applicability,product performance,environmental protection and occupational health,the technological requirements of automatic sample preparation system were researched systematically.16 main quality index parameters such as MTBF,and their requirements and testing method were proposed,which could be taken as the basis for formulation of product quality standards,and as the quality evaluation basis for manufacturers,users and the third parties.Usability index mainly include product reliability,maintainability and supportability,availability.The applicability indexes include the nominal maximum particle size of coal,the coal type and moisture,and the rated working capacity.Use performance indicators is measured by indicators such as coal sample loss rate of the entire system,the mass loss rate of fine powder in pulverizer,the precision of entire system sample preparation,the total moisture loss rate of the moisture sample preparation unit,the volatile matter bias of the drying unit,and the overall system ash bias.The environmental protection and occupational health indices consist of particulate matter emission,dust concentration and noise intensity in the sample preparation room.It is also recommended that the availability(A)index can be used to measure the manufacturer’s general level of design,manufacturing and services.
