EVA-625电梯/扶梯振动和噪音分析仪能够对电梯和扶梯的多项特性参数进行测量,如:噪音、运行距离、速度、加(减)速度、加加速度、振动、曳引力等,以及扶梯的梯级速度与扶手带速度差、梯级与裙板的安全间隙和摩擦系数等,而且测得的数据可以保存并由计算机处理以曲线图显示。ETCH01测速模块是EVA-625的一个附件,利用ETCH01可以测量扶梯的扶手带、梯级速度差以及扶梯的下行制停距离,对扶梯的日常检验工作有很大的帮助。 相似文献

TSGT70052012《电梯监督检验和定期检验规则——自动扶梯与自动人行道》已经于2012年7月1日起施行,其中第10.2项“扶手带的运行速度偏差”规定:扶手带的运行速度相对于梯级、踏板或者胶带实际速度的允许偏差为0-+2%。对应地,此项目要求的检验方法是用同步率测试仪等仪器来测量。因为笔者先前没有接触过同步率测试仪,在此就目前常用的另外两种测量方法进行分析。 相似文献

An experiment was conducted in a 20-level building to study the individual ascent speed on long stair. 165 college students, including 51 female students and 114 male students, took part in the experiment. Their ascent speeds and heart rates were recorded during they traveled upward. The experimental results show that their ascent speeds decrease continuously for the first 13–14 levels, then the ascent speeds keep at around 0.68 m/s for the males and 0.52 m/s for the females. Further study was conducted to explore the factors that might affect the ascent speeds on long stair. For the males, their ascent speeds show no obvious correlation with their body mass index and their scores of physical fitness test. For the females, it is observed that those who are overweight or fail in physical fitness test have the lowest ascent speed. After traveling upward around 18 levels, the average heart rates increase to 135 bpm and the average relative heart rates increase to 60% for the males, while the average heart rates increase to 150 bpm and the average relative heart rates increase to 70% for the females. Moreover, participates are more likely to use handrail for assistance as they move upward on higher levels. 相似文献

Energy consumption in Japan's houses has been increasing rapidly over the past decades. Furthermore, installation of 24-h ventilation systems in houses became mandatory last year, which will probably increase the heating, ventilation, and air conditioning (HVAC) energy consumption in Japan's houses. Regardless of these situations, natural energy utilization to reduce HVAC energy has not spread, especially in condominiums in Japan. In this study, we propose a new HVAC system for condominiums that makes use of solar heat, outdoor cool air by integrating elements in condominiums such as the balcony handrail, the 24-h ventilation system, and under-floor space. As a first step in the development of this system, we carried out experiments and computational fluid dynamics (CFD) studies on a solar heat collector integrated with the balcony handrail to determine its specification and to obtain information on its heat collection performance. As a second step, we calculated dynamic thermal load on a model condominium to evaluate the energy-saving performance and thermal comfort of the proposed system. The calculation results show that the proposed system has a high performance, both for energy saving and thermal comfort. 相似文献
