Date:2017-06-29 Author:senleijidian Click:

Ministry of Industry and Inion Technology of the People's Republic of China [2014] No. 32 Notice issued by the following five industry standards approved by the Press Committee.

1, JB / T11882-2014 "General use of water jet single screw air compressor"

This standard specifies the terms and definitions, symbols, basic parameters, requirements, test methods, inspection rules, marking, packaging and storage requirements for general water jet single screw air compressors. This standard applies to the drive motor power of 7.5kW ~ 250kW, rated discharge pressure of 0.4MPa, 0.70.8MPa, 1.0MPa of the general use of fixed and modified single screw air compressor. Other pressure level single screw air compressor can be implemented with reference to this standard.

2, JB / T11883-2014 "CNG master station and sub-station with gas booster compressor"

This standard specifies the terms, types and structure types, requirements, test methods, inspection rules, marking, packaging and storage of the CNG master station and sub-station pressurized compressor. This standard applies to the rated exhaust pressure of 25MPa, the motor power of not more than 355kW of the master station compressor and the motor power of not more than 90kW sub-station compressor. Compressors whose motor power is not in this range may be implemented with reference to this standard.

3, JB / T11884-2014 "non-lubricating carbon dioxide recovery with medium pressure compressor"

This standard specifies the basic parameters, technical requirements, test methods, inspection rules and marking, packaging and storage of medium pressure compressors for non-lubricating carbon dioxide recovery. This standard applies to the suction pressure of 0.002MPa ~ 0.02MPa, rated discharge pressure of 2.0MPa ~ 4.0MPa, driving the motor power of 90kW ~ 710kW compressor.

4, JB / T8935-2014 "Compressor safety requirements for process flow"

This standard specifies the safety requirements of the compressor for safety, safety devices and protective equipment. This standard applies to all types of process compressors and their ancillary equipment such as centrifugal, axial, reciprocating and rotary, including drives, intercoolers, buffers, separators or purifiers, interte connecting lines and lubrication, And water cooling systems.

This standard does not apply to:

A, GB22207-2008 "volumetric air compressor safety requirements" provisions of the air compressor; b, compressor parts of the basic mechanical design; c, compressor-related process device design and operation.

5, JB / T6430-2014 "general use of fuel injection screw air compressor"

This standard specifies the terms, symbols, basic parameters, requirements, test methods, inspection rules, marking, packaging and storage requirements for general use of fuel injection screw air compressors. This standard applies to the drive power of 2.2kW ~ 630kW, rated discharge pressure of 0.3MPa0.5MPa, 0.7MPa0.8MPa, 1.0MPa and 1.25MPa of the general use of fixed and modified screw air compressor. Rated air pressure of not more than 1.6MPa of other screw air compressor can also refer to the implementation of this standard. This standard does not apply to the general use of variable frequency fuel injection screw air compressor.
