For higher volumetric efficiency and lower launch cost of gear pumps with ultra low viscosity working medium used in spacecraft. In this paper, the volumetric efficiency formula of gear pumps was firstly derived from the two main leakages of axial gap and radial gap, At the same time, a new...
The method presented here can quickly show the effect of individual parameters on pump performance.With few input variables,easiness to program and quick calculation speed,it can predict performance of pumps under both designed and offdesigned modes.关键词: optimization design pump performance prediction...
This design measure dramatically increased the pumping capabilities and allowed continuous conveying of water to 13 m (corresponding to 42 ft) of height. We were able to stably operate these novel pumps for more than 30 000 combustion cycles. Therefore, they represent a further step toward long-...
Fluids is open-source software for engineers and technicians working in the fields of chemical, mechanical, or civil engineering. It includes modules for piping, fittings, pumps, tanks, compressible flow, open-channel flow, atmospheric properties, solar properties, particle size distributions, two phas...
Practical considerations in the design of CMOS charge pumps are discussed. The non-ideal effects of the charge pump due to the leakage current, the mismatch, and the delay offset in the P/FD are quantitatively analyzed. To use the appropriate charge pump in various PLL applications, several ar...
Design studies of distributed ion pumps 喜欢 0 阅读量: 20 作者: TS Chou 摘要: To upgrade the existing vacuum system, a new type of diode distributed ion pump (DIP) has been tested and developed for the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory. The new ...
The wave-induced motion of these joints is resisted by the two hydraulic rams, which pumps the high-pressure oil, and the high-pressure oil is fed into a high-capacity hydraulic high-pressure accumulator (HP) to provide some energy storage before being used to drive the hydraulic motor and ...

Adaptation of CFD to the Design of Centrifugal Pumps 来自 掌桥科研 喜欢 0 阅读量: 21 作者: S Yedidiah 摘要: The similarity between flow patterns predicted with the aid of CFD and those observed in practice indicates, that CFD might be capable to assist the pump -engineer in coming up ...
Financially sustainable strategies are needed to increase access to safe drinking water in low-income settings. We designed a novel in-line chlorine doser that employs the Venturi principle to automatically add liquid chlorine at the point of water colle
