Selection of Appropriate Control Valves for Vacuum Systems
It is believed that a vacuum system designed for precise vacuum control will be much better from ample technical point of views with the convenience of better performance. Vacuum control valves are used for this purpose. These valves are mechanical devices employed to start, stop, fine control, adjust and maintain the required vacuum levels as well as for desired accurate flow rates of the process fluid in the vacuum system. As systems of various vacuum ranges are the requirement of different processes and research works, therefore the selection of such valves for diverse vacuum ranges is the matter of prime importance. Moreover, selection of the proper vacuum valve also involves a thorough knowledge of the process and processing fluid for which it will be used, the material of which it is made, in what geometry the valve is to fit and the size it must has to perform its designated task accordingly. Further more, the possible adverse occurrences that can take place in the system should also be observed for appropriate valve operation. In this paper
Selection of Precise Vacuum Pumps for the Systems with Diverse Vacuum Ranges
Basically a vacuum pump is the most essential component of any vacuum system which is accountable to bring into being the required vacuum in the sealed setup, to accomplish a certain process. But for the broad vacuum range, all the vacuums cannot be generated by a single vacuum pump. Consequently, various pumps of distinct types are used to properly generate the vacuum of diverse ranges. Therefore, the selection of suitable vacuum pump or pumps to produce the required vacuum, for a particular vacuum work, is of primary importance. There are many factors that affect the suitable pump selection. In this paper, proper guidelines highlighting key criteria for selecting an appropriate vacuum pump, supportive for proper vacuum production has briefly been discussed that can make the task of pump selection simpler and exact.
