1. High efficiency: The centrifugal compressor has an efficient compression capacity and can quickly compress the gas to the required pressure. 2. Large capacity: Due to its high rotation speed, the centrifugal compressor can handle a large amount of gas, which is suitable for industrial ...
(R, κ, ν), centrifugal compressor flow field geometry and the degree to which the compressor flow field has been optimally designed, as well as on the compressor operating conditions (Mach number, Reynolds number), which determine the work coefficient (ψ) and compressor efficiency (η) (...
the compressor efficiency drops off dramatically. Where there is tower water relief (decreasing tower water temperature), variable speed drives can be used to improve part load efficiency. By utilizing two compressors on a common refrigeration circuit, it is possible to greatly improve the part load...
efficiency of a centrifugal compressor under capacity control, by providing a linkage in the slit of the diffuser vane of the compressor to drive the diffuser vane and inlet guide vane in connection with each other and by determining the form of the slit in terms of a prescribed formula. CONS...
or make structural modifications to the centrifugal compressor. For example, by changing the gear arrangement, the speed of the impeller can be slowed, thereby adjusting the impeller Mach number to provide better efficiency. Such methods are expensive and also have other disadvantages which will be ...
efficiency and operability that are typical of a more complex system constituted by a standard centrifugal compressor for dry gases preceded by scrubbers or separators, but to do so by using smaller, simpler and cheaper scrubbers and separators. This becomes possible by means of a wet compressor ...
Because the extra channels (5, 10, 11) are solely sound wave transmitting suppression of disturbances in the flow and consequent instabilities with decreased efficiency and increased noise is achieved. The extra channels (5, 10, 11) can be flow channels of conventional type, but with one or ...
The present invention provides a centrifugal barrel polishing apparatus, which is capable of maintaining or improving the polishing efficiency while increasing the polishing amount. 离心滚筒研磨装置(10),通过向进行行星旋转的多个滚筒槽(12)中投入工件和研磨石从而用研磨石对工件进行研磨,其中,在将N定义为滚筒...
FIG. 2 is a graph showing a map of compressor efficiency as a function of operating speeds and pressure ratios across the machine. FIG. 3 is a graph using data from a VPSA cycle using a centrifugal machine. DETAILED DESCRIPTION OF THE INVENTION ...
Compressor efficiency variation with rotor tip gap is assessed using numerical simulations on an embedded stage representative of that in a large industrial gas turbine with Reynolds number 锝 2 脳 10~6 to 7 脳 10~6. The results reveal t... S Sakulkaew,CS Tan,E Donahoo,... - 《Journal...
