我厂一台4t/h链条炉排卧式快装锅炉配用的是GSQ81-I小车式上煤器。该上煤器在运转中存在两个问题,我们对其进行了改进。 一、上煤器传动轴的敢进 原上煤器传动轴为一钢管,两端套在连接轴的轴颈上,径向穿销子传递粗矩。由于钢管壁较薄,... 我厂一台4t/h链条炉排卧式快装锅炉配用的是GSQ81-I小车式上煤器。该上煤器在运转中存在两个问题,我们对其进行了改进。 一、上煤器传动轴的敢进 原上煤器传动轴为一钢管,两端套在连接轴的轴颈上,径向穿销子传递粗矩。由于钢管壁较薄,材料较软,钢管与轴颈配合有间隙。 展开更多

Mathematical morphology is widely applicated in digital image procesing.Vari- ary morphology construction and algorithm being developed are used in deferent digital image processing.The basic idea of mathematical morphology is to use construction ele- ment measure image morphology for solving understand problem.The article presented advanced cellular neural network that forms mathematical morphological cellular neural network (MMCNN) equation to be suit for mathematical morphology filter.It gave the theo- ries of MMCNN dynamic extent and stable state.It is evidenced that arrived mathematical morphology filter through steady of dynamic process in definite condition. 展开更多
