Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 9234-2008 "motorized reciprocating pump". Compared with GB/T 9234-2008, the main technical changes of this standard except for editorial changes are as follows. --- Expanded the scope of the standard, increased the "coal to oil" medium, flow expansion to 650m3/L (see Chapter 1,.2008 edition of the first Chapter 1); --- Improved pump performance requirements, pump efficiency and pump volume factor have been improved (see Table 1, Table 1 of the.2008 edition); --- Increased the noise requirements of the pump, the highest noise value decreased by 1dB~3dB (sound pressure level) as a whole (see Table 2,.2008 edition) Table 2); --- Increased the reliability requirements of the pump, and increased the operating life of the first overhaul from 12000h to.20000h (see 5.4.2,.2008). Version 5.4.2); --- Increased the life requirements of the wearing parts of the pump, wherein the valve group life index requirements are specified separately according to the medium (see Table 3,.2008) Table 3 of the annual edition); --- Modify the non-destructive testing requirements for shafts and crankshafts, no longer limit the specific non-destructive testing methods (see 5.5.1.1, 5.5.1.1 of the.2008 edition); --- Increase the requirements of the variable speed prime mover and the inverter governor (see 5.12.2.3, 5.12.2.4); --- Increased the pump outlet pressure must not exceed 1.25 times the pump rated discharge when the safety relief device with full discharge function is activated Pressure (see 5.12.6.3); --- Change the "pulsation stabilization device" to "pulse suppression device" to increase the recommended technical requirements for the pulsation suppression device (see 5.12.7, Appendix C, 5.12.7 of the.2008 edition). This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Pump Standardization Technical Committee (SAC/TC211).
