分格转子定量喂煤装置材料与加工
来 源:www.gtzdh.com.cn     发布时间:2018-4-14 10:47:23

壳体材料选用QT500-7,经铸造、回火、喷丸等机械加工工艺后,消除了铸造应力,提高表面精度,保证装置以后长期使用不变形。分格转子和密封板材料选用特种合金,保证合理的硬度和表面粗糙度匹配特性,提高了二者综合使用寿命。出料头为耐磨材料,并且内表面涂覆耐磨层,延长使用寿命。转轴采用锻造40Cr并结合一定的热处理,使其强度、塑性和韧性具有良好的配合,轴头具有很高的耐磨性,提高了轴的使用寿命。

本装置结构外形复杂,各个部件之间具有很多关联孔系,并且要求精度高,所以零部件基本都选择在数控机床上加工,孔系定位误差精确到0.01mm。这样,计量轴线和计量点的位置度精度高,零部件之间装配产生的应力小,计量部件灵敏性高、阻尼小,从而保证了本系统具有很高的灵敏度和计量精度。

The shell material is made of QT500-7. After casting, tempering and shot peening, the casting stress is eliminated, and the surface accuracy is improved, so that the device can be used for a long time without deformation. The separator rotor and the sealing plate materials are made of special alloy, which guarantees reasonable hardness and surface roughness matching characteristics, and improves the comprehensive service life of the two. A material for wear-resistant material, and the inner surface coating wear-resisting layer, prolong the service life. The shaft is made of forged 40Cr and combined with certain heat treatment to make its strength, plasticity and toughness well matched. The shaft head has high wear resistance and improves the service life of the shaft.

The utility model has the advantages of complicated structure, various connecting holes between each component, and high precision required, so the parts are selected to be processed on the numerical control machine tool, and the positioning error of the holes is accurate to 0.01mm. In this way, the position of the precision of the measurement axis and the measurement point, generating assembly components between the stress of small, high sensitivity and small damping measurement components, so as to ensure the system has high measurement accuracy and sensitivity.
