GB/T3853—1998bZxz.net
This standard is based on the international standard 1217:1996 Volumetric air compressor acceptance test, and revises the original GB363-83-1998 performance test method of volumetric air compressor. Except for Appendix A, the technical content of this standard is equivalent to that of the international standard. When revising my country (R3855) according to ISO1501217, the liquid compressor test method specified in Appendix A of ISO1217 was considered. However, this part is not a compressor specialty in China, and there is no corresponding international standard. Therefore, it was not adopted in ISO853. At the same time, the original B285311 part of the performance test of air compressors has been proved to be suitable for my country's national conditions through practice, and it does not conflict with other standards. When revising, this part of the content was retained and listed in the new standard in the form of a new standard, replacing the content of the A-type compressor. In this way, the arrangement of the entire standard is also consistent with the international standard. 6. Compared with the original GI3353-85, this standard has a greater scope of application, making it applicable to all types of conventional press machines. It is the first "general standard" and has replaced the first standard (GB3353·B3) since its implementation. The appendixes H, E, F and F of this standard are all indicative appendices of the standard, and the appendixes E and F are indicative appendices. This standard was proposed by the Ministry of Machinery Industry of the People's Republic of China. This standard was submitted by the National Press Standardization Technical Committee. The drafting unit of this standard is: General Machinery Research Institute of the Ministry of Machinery Industry. The person who drafted this standard is: Xue Zhengxue GB/T3853—1998
ISO Foreword
ISO (International Organization for Standardization) is a worldwide federation of national standardization bodies (ISOs). International standards are work done by technical committees of ISO. Each member has the right to participate in the work of the committee if it is responsible for the establishment of the technical requirements. The relevant international organizations that maintain contact with ISO (official or unofficial) may also participate in relevant cooperation. In the field of electrotechnical standardization, ISO maintains a close working relationship with the Technical Committee of Electrotechnical Engineering (TEC). It publishes the general plan of international standards adopted by the technical committee. After being submitted to the member groups for secretion, it will take at least the consent of the members to be voted and released as a national standard. The international standard [S12_7] is formulated by the Technical Committee of 1130/1℃118\machines, pneumatic tools and pneumatic machinery. This is the first edition of the standard, which replaces the required version (S) 1217-1) and has been fully technically specified. The appendix is for the part of the European standard that specifies the combustion gases. Appendix F, Appendix F and Appendix G are for reference only

5.2.1 General
5.2.1.1 The measuring joints of pipelines and gas storage pipes shall be vertical and flush with the inner wall. Note 10: For low-pressure or high-flow pressure, attention should be paid to the subtle technical principles such as hairline, which may cause great errors. 5.2.1.2 The length of the pressure pipe shall be as short as possible, and its sealing shall be inspected to eliminate any leakage. 5.2.1.3 The pipes should be as airtight as possible, have a diameter of sufficient size and be able to prevent the increase of cold caused by dirt. The two measuring instruments of liquid or gas mixture should be installed at the same location as the intake point. The depth of the pipe should not change the influence of the height of the pipe. Otherwise, the influence of high pressure should be considered. The sealing test should be carried out to exclude all leakage. 5.2.1.4 The instrument should be safe so that it will not be affected by harmful side effects. 5.2.1.5.2.1.6 The total pressure is the sum of the static pressure and the dynamic pressure. The pitot tube is used to measure the pressure. The axis of the pitot tube is in the direction of the fluid flow. When the dynamic pressure is less than 5% of the total pressure, the pressure wave amplitude of the low frequency (1H2) pressure in the suction or exhaust energy exceeds 1% of the average pressure in the main body, the installation of the general pedal should be changed before the test.
5.2.1.8 The pressure transmitter is used for the test. Under the condition of the pressure and the main body pressure, the pressure transmitter shall be calibrated by an electronic pressure gauge with equivalent accuracy:
5.2.1.9 The accuracy of the reading and the compensation code shall be adjusted according to the instrument. 5.2.1.10 The filter sample reading should be corrected according to the current flow. 5.2.1.11 Under the condition of the bottle (1H) breathing flow regulation, the pressure gauge should be installed between the pressure gauge and the pressure gauge.
5.2.1.12 Do not place the pressure gauge before the pressure is produced. The throttling valve can reduce the pressure gauge. The throttling hole can be used. 5.2.2 Atmospheric pressure
The atmospheric pressure is higher than 15% of the gas meter. 5.2.3 Intercooler, J
CH/T3853—199B

5.3.1 A certified or calibrated receiver with a relative temperature not less than ±1K, such as a thermoelectric valve, a resistor temperature or a relatively low temperature electric organ, should be placed in the Ning Li terminal to measure the temperature.
5.3.2 The thermometer should be as thin as possible and its diameter should be as small as possible. Its surface should be corrosion-resistant and oxidized. The sleeve should be filled with appropriate liquid.
5.3.3 The thermometer sleeve should be inserted into the tube 1mm or 1/10mm in diameter. For small diameter parts, partial insertion or other local elimination should be used to ensure the accuracy of the display.
5.3.4 When reading, the thermometer should not be removed from the medium. When using a sleeve, it should not be removed from the tube. 5.3.5 Take staggered measures to ensure that the area near the insertion point and the protruding parts of the connecting parts are well insulated so that they are actually in the same position as the entire device: b) The sensors and temperature sheaths of various instruments can allow the medium to pass through well (the sensor and the negative tube of the thermometer should be countercurrent. In extreme cases, a position that is still lower than the normal position can be adopted to avoid the flow of medium (the thermometer tube is not resistant to the flow of medium). 5.3.6 The thermocouple has a welded hot end and should be calibrated together with its wire within the specified range of use. Thermocouples should be made of materials that combine temperature measurement and gas. If a thermometer sheath is used, the hot end of the thermocouple should be connected to the bottom of the tube as much as possible. 5.4 Important measurements: If the gas contains moisture, it should be tested during the test: It should be used in the standard inhalation position.

The test piece should be placed under conditions comparable to the test product. The torque meter and the torque element should be verified together. The defect: the load reading should be increased at the same time. The load should not be reduced during the reading. Similarly, the load quotient should not be increased when the load reading is reduced. The range increase is determined by verification, and the average of the load readings is used as the basis. The meter measures the new block rate. If the difference between the load increase and decrease section is more than 1, the instrument fails. 5.7.4 The motor drive shaft power should be determined by measuring the input power and then multiplying it by the motor efficiency. The motor efficiency can be obtained from the certified motor. Auxiliary power meters should be used to measure the power. The voltage and current meters should be connected to the motor terminals to ensure that the voltage drop of the cable does not affect the measurement. If control instruments are used, the cable samples should be determined separately and the measurement results should be considered: GB/T38531998
5.5 The required power calculation point is the input connection point. The voltage drop in the cable or the measurement result should be optimized. 5.7.6 For three-sweep motors, the power should be measured by the two-wattmeter method or other related methods. 5.7-7 Current and voltage inductors should be selected to operate as close to their rated load as possible to reduce their ratio errors. During the test, it may be very convenient to connect a recently calibrated watt-hour meter to the power group for checking. 5.8 Common test panels

The condensate collected in the condenser, the gas station and the "gas method" and other places between the flow measurement panel can be measured. Each test Before and after the operation, the refrigerant in the intercooler and its separator should be drained. Before the compressor is discharged, the condensate should be weighed according to the interval time from the last operation. Note: Before measuring the net liquid quality, the oil carried over should be reduced. 5.9 Verification of the instrument
Before the test, the original records of the instrument should be kept. For those main instruments, the calibration values are prone to change during the test, and they should be calibrated again. If the change value is out of the instrument grade range, the test will not be recognized. 6 Test Engineer

5.3.1 A certified or calibrated receiver with a temperature not lower than ±1K, such as a thermoelectric valve, a resistor temperature or a relatively low temperature electric valve, should be placed in the inner end of the measuring plate.
5.3.2 The thermometer should be as thin as possible and its diameter as small as possible. Its surface should be corrosion-resistant and oxidation-resistant. The sleeve should be filled with appropriate liquid.
5.3.3 The temperature 1 sleeve should be inserted into the tube 1mm or 1/1. If the diameter is too small, local insertion or other local elimination should be used to ensure the accuracy of the video disk.
5.3.4 When reading, the display should not be taken out of the medium being measured. When using a sleeve, it should not be taken out of the attenuation tube. 5.3.5 Take staggered measures to ensure that the area near the insertion point and the protruding parts of the connecting parts are well insulated so that they are actually in the same position as the entire device: b) The sensors and temperature sheaths of various instruments can allow the medium to pass through well (the sensor and the negative tube of the thermometer should be countercurrent. In extreme cases, a position that is still lower than the normal position can be adopted to avoid the flow of medium (the thermometer tube is not resistant to the flow of medium). 5.3.6 The thermocouple has a welded hot end and should be calibrated together with its wire within the specified range of use. Thermocouples should be made of materials that combine temperature measurement and gas. If a thermometer sheath is used, the hot end of the thermocouple should be connected to the bottom of the tube as much as possible. 5.4 Important measurements: If the gas contains moisture, it should be tested during the test: It should be used in the standard inhalation position.

5.7.1 The input power of the compressor should be measured by a dynamometer or torque meter, or the input resistance power of a calibrated power source or the performance of a recognized driving engine should be used to determine the input power of the compressor. 5.7.2 The power of the original engine should be measured according to the technically recognized test specifications. 5.7.3 The precision torque meter should not be used at less than one-third of its rated torque. The test piece should be placed under conditions comparable to the test product. The torque meter and the torque element should be verified together. The defect: the load reading should be increased at the same time. The load should not be reduced during the reading. Similarly, the load quotient should not be increased when the load reading is reduced. The range increase is determined by verification, and the average of the load readings is used as the basis. The meter measures the new block rate. If the difference between the load increase and decrease section is more than 1, the instrument fails. 5.7.4 The motor drive shaft power should be determined by measuring the input power and then multiplying it by the motor efficiency. The motor efficiency can be obtained from the certified motor. Auxiliary power meters should be used to measure the power. The voltage and current meters should be connected to the motor terminals to ensure that the voltage drop of the cable does not affect the measurement. If control instruments are used, the cable samples should be determined separately and the measurement results should be considered: GB/T38531998
5.5 The required power calculation point is the input connection point. The voltage drop in the cable or the measurement result should be optimized. 5.7.6 For three-sweep motors, the power should be measured by the two-wattmeter method or other related methods. 5.7-7 Current and voltage inductors should be selected to operate as close to their rated load as possible to reduce their ratio errors. During the test, it may be very convenient to connect a recently calibrated watt-hour meter to the power group for checking. 5.8 Common test panels
