ComprCheck is a comprehensive tool kit for design, operation, fabrication and maintenance of diaphragm compressor. It is a good reference for engineer, sales, shop assembler, field service personnel. This App is designed for Diaphragm Compressors but can provide reference to other types of gas compressors as well. ComprCheck includes 19 calculators and data charts. These calculators and charts cover the following areas of diaphragm compressor: (1) Compressor Process - Overall and Stage Compression Ratio - Discharge Temperature - Heat Load of Compression Process - Flow Conversion from Volumetric to Mass Rate (2) Compressor Piping - Working Pressure of Pipe and Tube - Working Pressure Chart of ANSI Flanges - Flange Bolting Torque - Gas Velocity (3) Belt Drive System - Drive Belt length - Center Distance - Motor Sheave Size - Motor Dimension (4) Hydrogen - Conversions of Flow Rate - Conversions of Power - Capacity of Hydrogen Vessel (5) Miscellaneous - Lifting Weight of Compressor Head Parts - Bolt Thread Comparison (British and Metric) - Pressure Release Time - Unit Conversions of Temperature, Pressure, Volume, Flow, Mass, Length and Torque
Version History a few fixes newly add a PSV sizing tool in Flow/PSV to help the selection of PSV with a proper orifice size PSV Orifice - Gas PSV Orifice - Liquid Enter Process Medium, Flow Rate, Set Pressure, and Temperature, then the orifice area (diameter) will be calculated, then you are able to select a orifice size. 3.3 03/01/2024 Fixed a few errors... 3.0.2 09/29/2022 - Fixed a few typos and errors. - Added two calcs: "Pressure Drop for Dry Gas" and " Pipe Cv" Thanks for your continuous support! 3.0.1 08/16/2022 Fixed some errors. Added two new sections: - "Piping", which includes pipe-related application "Bend Radius" and " Spacing". - "Code", which introduces compressor-related codes and standards; initially, ASME-related codes are includes. Thanks for your continued supports in the past year! Happy new Year 2022! 2.2.0 01/01/2022 fixed a few issues and added "Predicted Flow" calculation. Thanks for your continuous supports! 2.1.0 12/03/2021 fixed a few errors and added new calculations: - pressure drop in "Pressure" - unbalanced forces in "More" Now, 40 calculations or charts are included in this application, updated to Version 2.0.0. Again, welcome your comments and thank you for your continuous support! 2.0.0 07/31/2021 Fixed some typos and added a few new calculations: double-pipe heat exchanger, motor power and etc. Total: 39 of reference calculations or charts now.
