摘要： A centrifugal pump with a rotating impeller and a rotating diffuser. The diffuser may be rotated with a controlled speed to broaden the operational range of the pump. Such control may be done independently of the rotational speed of the impeller to tailor pump operation to a particular NPSH, efficiency, fluid flow or related requirement. In one preferred form, the impeller and diffuser are made to counter-rotate relative to one another, while the independent rotational speed of each may be provided by one or more motors, as well as a variable-speed transmission coupled to such motor or motors. Such a pump is optimized for specific speed operating ranges beneath those associated with axial flow pump configurations.

摘要： A cleaning device for cleaning an outer cylindrical surface of an impression cylinder of a rotary printing machine includes a cleaning cloth pressed against the outer cylindrical surface by a beam. The beam is pivotally mounted to engage the cleaning cloth with the outer cylindrical surface upon pressurization of a pneumatic cylinder. A spring pivotally returns the beam to disengage the cleaning cloth with the outer cylindrical surface upon depressurization of the pneumatic cylinder. To assure radial clearance between the cleaning device and the gripper fingers of the impression cylinder, the pneumatic cylinder is depressurized at a first angular position of the impression cylinder and the pneumatic cylinder is subsequently pressurized at a second angular position of the impression cylinder. The first and second angular positions of the impression cylinder correspond respectively to the cleaning device nearing the vicinity of the gripper fingers and the cleaning device leaving the vicinity of the gripper fingers. The cleaning device includes a cam roller that engages a cam plate attached to the impression cylinder to control the engagement of the cleaning device with the outer cylindrical surface upon the pressurization of the pneumatic cylinder.
摘要翻译：用于清洁旋转印刷机的压印滚筒的外圆柱形表面的清洁装置包括通过横梁压靠外圆柱形表面的清洁布。梁被枢转地安装以在气压缸加压时将清洁布与外圆柱形表面接合。当气压缸减压时，弹簧枢转地返回梁以使清洁布与外圆柱形表面脱离接触。为了确保清洁装置和压印滚筒的夹持器指状件之间的径向间隙，气动缸在压印滚筒的第一角度位置处被减压，并且气压缸随后在压印滚筒的第二角度位置被加压。压印滚筒的第一和第二角度位置分别对应于靠近夹持器指状物附近的清洁装置以及离开夹持器手指附近的清洁装置。清洁装置包括凸轮辊，该凸轮辊与附接到压印滚筒的凸轮板接合，以在气动缸的加压时控制清洁装置与外圆柱形表面的接合。

摘要： A cleaning device provided on a rotary printing machine for cleaning the outer cylindrical surfaces of cylinders includes a pressing-on bar for pressing a cleaning cloth on a respective outer cylindrical surface, adjusting elements for engaging the pressing-on bar, and an elastic profile rail to guide and press a cleaning cloth onto an outer cylindrical surface over the entire cylinder width. The elastic profile rail receives a plurality of forces from spring elements. The elastic profile rail and the spring elements allow a uniform cleaning of the outer cylindrical surface despite the presence of uneven or rough portions of the outer cylindrical surface that might be encountered by the cleaning device during cleaning.
