HDTV HJ14ex4.3B IRSE / IASE In recent years, demand for HD production has steadily expanded to encompass a broad variety of program genres. Under such circumstances, the HJ17ex7.6B has seen a worldwide rise in popularity as a standard HD lens having high performance and ease of operation. The HJ17ex7.6B is a lens whose central design criteria were low weight and small physical size to support greater mobility especially for HD newsgathering. It also provides a short MOD of only 0.56m in response to a strong market request. With its high optical imaging qualities the HJ17ex7.6B is distinguished within the HDxs lens series by a high price performance ratio that facilitates many forms of HD program origination. A newly developed digital drive-unit further streamlines the lens ergonomics and ease of operation that empowers camera operator shooting flexibility. (New drive is loaded with the lens that has ‘A' at the end of its model name such as ‘IRSE A', ‘IASE A'.) 详细介绍 HJ17ex7.6B IRSE A / IASE A In recent years, demand for HD production has steadily expanded to encompass a broad variety of program genres.

(New drive is loaded with the lens that has ‘A' at the end of its model name such as ‘IRSE A', ‘IASE A'.) Main Features Realization of Miniaturization and Weight Reduction The new design achieved a reduction in size that produced a total length of 206.4mm while also reducing the weight of the lens to 1.60kg (IRSE A type) which is crucial to more mobile shooting. Attention to the lens front end design in the form of an optical port diameter of only 82mm and a hood reduced in size so as to not occlude the camera operators viewing of the scene while shooting, further contribute to the dynamic shooting capabilities of the lens. Short Minimum Object Distance of 0.56m By reducing the minimum object distance to 0.56m the lens can be better utilized within confined spaces allowing objects to be effectively imaged at short distances while operating with a wide angle of view facilitated by the minimum 7.6mm focal length.

安徽15KW三相汽油发电机注意油压表的显示仍然不符合要求。这是跟踪故障分析和采取纠正措施的重要方法。根据静音发电机组的工作流程方向,这确保了机器的曲轴和发电机的转子的同心度在规定的范围内,交互机和调速器的组合是自动调节系统,并且在静音发生器成功启动后3分钟指定负载。为了确保核电站应急静音发电机组的可靠运行!发电机组由熟悉设备结构并具有安全操作程序的人员操作,当轴承在多尘和潮湿的环境中使用时。发电机
20kw柴油发电机厂家配送作为市电和UPS的后备电源,需求保证其随时可用。因为柴油中含有量的蜡,在冬天气温较低的时分,这些蜡会逐步分出,乃至致使柴油凝结无法活动。当柴油分出的蜡开端堵塞滤清器然后影响油路的正常供油时,此刻的温度称为柴油的冷虑点。以0号柴油为例,其凝结点为0摄氏度,冷滤点为4摄氏度。通常在室外温度低于5摄氏度时,敞开电加热功用,使得柴油的状况抱负,可随时投入作业。电加热会耗费量的电能
30千瓦柴油发电机采购供货安装完毕后,进入初期和调试阶段需要注意哪些问题? 大泽应急柴油发电机组根据多年的经验总结了以下几点。 如果忽视这些细节,可能会给柴油发电机组后期运行埋下风险,给用户带来不必要的损失。初次应急柴油发电机组时,应注意以下几点:1、检查应急柴油发电机组是否剧烈晃动。 若机组剧烈晃动,应立即停车检查分析原因;2、检查应急柴油发电机组增速时是否有异常声音。 如有,应停车检查;3、检
大泽救济用25kw柴油发电机设计之初发动机的核心部件,曲轴的设计关系到整个发动机的可靠性。 以往传统的截面法只能校核曲轴几个危险截面的有限强度。 现在有限元分析为我们提供了一种新的曲轴应力连续计算方法。 使用这种方法,可以计算各种应力。 对复杂零件进行更有效的应力计算和强度校核,使设计更加合理,可靠性更好。救济用25kw柴油发电机参数如下;型号:TO28000ET一:发电机参数:1.额定功率:25
