Foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents"
Drafting:
This document replaces GB/T 13930-2010 "Method for determination of gas volume of water ring vacuum pumps and water ring compressors" and GB/T 13930-
Compared with:2010, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
--- Changed the installation diagram of the orifice throttling device on the water ring vacuum pump test device (see Figure 3, Figure 3 of the:2010 edition);
--- Changed the installation diagram of the orifice throttling device on the water ring compressor test device (see Figure 4, Figure 4 of the:2010 edition);
---Changed the orifice throttling device series, clarified the relationship between the orifice thickness and the "maximum flow measurement value" and "maximum differential pressure value of the differential pressure gauge"
(See Table 1, Table 1 of the:2010 edition);
--- Changed the measurement unit of the throttle orifice pressure difference from mm to hPa (see Table 1, Table 1 of the:2010 edition);
--- Changed the installation diagram of the metering nozzle on the water ring vacuum pump test device (see Figure A:2, Figure A:2 of the:2010 edition);
--- Deleted the metering nozzle dry air table flow rate (see Table A:2 of the:2010 edition):
