ASME PTC 30-1991 空气冷却式热交换器

The object of this Code is to provide uniform methods and procedures for testing the thermodynamic and fluid mechanical performance of air cooled heat exchangers, and for calculating adjustments to the test results to design conditions for comparison with the guarantee as defined in para. 5.9.4. The scope of this Code covers, but is not limited to, the testing of mechanical draft heat exchangers, of both the forced draft and induced draft types, natural draft heat exchangers, and fan assisted natural draft heat exchangers. From a heat transfer surface standpoint, this Code covers all tube bundle orientations, including: vertical, horizontal, and slanted conduit heat exchangers. Both bare surfaces and finned surfaces are included as conduit type heat exchanger components. While conventional round tubes with circular fins are assumed in this Code, the procedures can be modified by mutual agreement to apply to other surface configurations. While the cooling fluid is restricted to atmospheric air, the tube-side fluid can be any chemical element, compound or mixture, in single phase flow, liquid or gas, or in two phase flow. This Code is written under the assumption that the Air Cooled Heat Exchanger (ACHE) may be tested as having a discrete process stream or that only one process fluid stream is being investigated. In other cases, modifications must be made to the procedures presented. Such modifications shall be agreed by the parties to the test. The scope of this Code also includes, directly or by reference, recommended methods for obtaining data, measurements, observations, and samples to determine the following: (a) Physical Dimensions (b) Air Flow Rate (c) Air-Side Pressure Differential (d) Fan Driver Power (e) Sound Level (f) Atmospheric Pressure (g) Environmental Effects (h) Wind Velocity (i) Air Temperatures (j) Entering Air Temperature (k) Exit Air Temperature (l) Process Fluid Temperatures (m) Process Fluid Pressures (n) Process Fluid Flow Rate (o) Composition of Process Fluid (p) Percent capability (q) Process Fluid Pressure Drop

ASTM D1287-91(2002) 发动机冷却剂和防锈剂的pH值的试验方法

pH is a measure of the hydrogen ion concentration and indicates whether an engine coolant, antirust, or a solution of these compounds is acidic, alkaline, or neutral. pH is sometimes used for production quality control. It is generally desirable that engine coolants have an alkaline pH. pH is not significant from the standpoint of predicting service life. The pH of used engine coolants or antirust solutions is not a dependable indication of either existing effectiveness or remaining life of the solution.1.1 This test method covers the determination of the pH of unused engine coolants and antirusts, and used or unused aqueous dilutions of the concentrated products. Note 18212;Antirusts in solid form are not included in this test method.Note 28212;It is believed that this procedure gives all the information required for determining the pH of samples of engine coolant or antirust likely to be encountered. Should additional information on pH determinations be needed, reference should be made to Test Method E 70.1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
