Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document supersedes GB/T 18300-2011 "Technical Conditions for Automatic Control Sodium Ion Exchangers". Compared with GB/T 18300-2011, Apart from structural adjustments and editorial changes, the main technical changes are as follows. a) The wording of "scope" has been changed (see Chapter 1, Chapter 1 of the.2011 edition); b) Modified the following settings for "Automatic Control Sodium Ion Exchanger," "Operating Cycle," "Operating Temperature," "Regeneration," "Co-current Regeneration," "Counter-current Regeneration," and "Displacement."

Table 4 (2011 edition) i) The requirement for "using controllers with voltages exceeding 36V" has been changed (see 5.1.3.2,.2011 version 5.1.3.2), adding "using..." Requirements for "flow-type controllers", "controllers using online monitoring", and "controllers using chip-controlled operation and regeneration processes". (See 5.1.3.4~5.1.3.6); j) The "inlet water temperature" was changed to "operating temperature," and the "requirements for free chlorine in the inlet water quality" were modified (see Table 5, Table 5 in the.2011 edition); k) Added "Requirements for materials in contact with water in civil heat exchangers" (see 5.3.2); l) Added "Requirements for tanks made of composite materials such as fiberglass" (see 5.4.1); m) Added "The optional controller, brine system, exchange tank and its filling resin should meet the user's requirements for the exchanger's water production capacity and cycle time." Requirements for water quantity, effluent quality, and regeneration, etc. (see 5.5.2); n) Added content related to "Installation" and "Debugging" (see 5.6~5.7); o) The structure of "Inspection and Test Methods" has been changed, categorized by test objects based on different locations, and listed by category. The corresponding test items, requirements, and methods (see Chapter 6, Chapter 6 of the.2011 edition); p) "Material Quality" has been changed to "Basic Requirements" (see 6.1,.2011 version 6.1), and "Automatic Control of Sodium Ion Exchanger Inspection" has been added. The inspection and testing include inspection of the exchange tank, inspection of the controller, and performance testing of the exchanger (see 6.1.2,.2011 version 6.1.2); q) A "Quality Inspection Standard for Fiberglass Tanks" has been added (see 6.2.1.2); r) The "Pressure Test Requirements for Exchange Tanks" have been changed (see 6.2.2, 6.4 in the.2011 edition), and the "Hydrostatic Pressure Test Requirements" have also been changed. The requirement for "cyclic pressure testing (for non-metallic parts only)" (see Table 6,.2011 edition) has been removed, along with the requirement for "burst pressure testing". (For non-metallic components only) The relevant requirements (see Table 6 of the.2011 edition) have been expanded to include "the water used for pressure testing should be clean water" and "not..." The requirements for water used in the pressure test of stainless steel tanks (see 6.2.2.2) have been expanded to include a requirement of "passing the pressure test" (see 6.2.2.4). s) Added "Test methods and acceptance requirements for fault-free operation" (see 6.3.1) and "Test of dielectric strength and insulation resistance of controller insulation". The requirements and test methods (see 6.3.2) and the requirements for withstand pressure test (see 6.3.3.2) have been revised, and the withstand pressure test of the controller has been modified. The requirements for "requirements" and "cyclic pressure test (for non-metallic containers only) pressure resistance test requirements" (see 6.3.3, 6.4 in the.2011 edition) have been deleted. "Burst pressure requirements and test methods for controllers" (see Table 6 in the.2011 edition); t) Added "Running and Regeneration Start-up Control Performance Test" (see 6.4.4); u) Added definitions, inspection nature, and requirements for "type testing" and "factory inspection" (see 7.1.2 and 7.1.3); v) The normal production time has been changed from "24 months" to "48 months" (see 7.1.4, 7.1.2 in the.2011 version); w) The "burst pressure test" item for the "exchange tank" and "controller" components has been removed (see Table 7 in the.2011 edition).
