Foreword
This standard is JG/T 3009-1993 "computer-controlled variable frequency speed control water supply equipment" amendment.
This standard and JG/T 3009-1993 compared to the main technical changes are as follows.
--- In the scope of the provisions of the revised theme, an increase of the pressure applied to the boundaries of work and water temperature, pointed out that does not apply
limit;
--- Increased computer-controlled variable frequency speed control water supply equipment, rated water flow, equipment head, pressure control error, overpressure protection term
And defines and modifies the expression of the terms, points out the composition of microcomputer-controlled frequency conversion speed regulating water supply equipment;
--- In the classification of the provisions of the deleted by the control mode, structure, control the number of pumps the classification, an increase of medium temperature plan
Points, and added the model's markings and examples;
--- The "working conditions" as an external separate column, and increased the vertical installation of tilt, power supply voltage, power frequency, power supply
Power requirements
--- Increased the structure and layout, appearance quality, water pump, equipment configuration, the basic material requirements, modify the health performance requirements
(See 6.1);
--- Increased water supply capacity, low-flow operation, manual, automatic and remote control, overpressure protection, automatic pump switch
Function, standby pump since the cast function, noise and vibration performance requirements, modify the water level control, pressure control, automatic insurance
Protection function, compressive strength, anti-interference, anti-harmonic pollution requirements, an increase of remote monitoring, monitoring, monitoring functions, man-machine
Optional features for the port function, end water level communication interface functions, deletion of low temperature storage test, high temperature storage test, transport
Test requirements (see 6.2);
--- In the control cabinet requirements, the control cabinet shell modified level and the control cabinet wire, light and button color to be
Seeking, increase the requirements of lightning protection, drop test (see 6.3 and Appendix B);
--- Increased the selection of pump units, as well as the suction pipe, the configuration of the outlet pipe, the tube flow rate requirements (see 6.4);
--- Increased the use of pipes, fittings, valves, gauges, pressure tank requirements, and increased processing, welding requirements (see 6.5 and
6.6);
--- Increased the provisions of the test instruments used, modified equipment test equipment, modify or increase the requirements of the corresponding test methods (see
Chapter 7 and Appendix C, Appendix D);
--- Modify the logo, packaging, transport requirements (see 9.1, 9.2 and 9.3);
--- Increasing the requirements of the inverter (see Appendix A).
