GB 3853-83 - Performance of general positive displacement air compressors (6)

An Introduction to GB 3853-83 General Purpose Volume Air Compressors GB 3853-83 is the industrial standard for general purpose volume air compressors. This document provides the performance requirements and test methods for the evaluation and classification of general purpose volume air compressors. It applies only to general purpose volume air compressors that are self-contained and driven by an electric motor or spark ignition internal combustion engine. This standard is applicable to all general purpose volume air compressors that are used on a wide variety of industrial, commercial, and domestic applications. Overview of GB 3853-83 General purpose volume air compressors are intended for use in compressible fluids such as air, water, and oil. They are used for a variety of purposes, including refrigerant systems, air-conditioning, metallic and woodworking, tool construction and repair, and industrial packaging and material handling. The GB 3853-83 standard provides performance requirements and test methods for the evaluation and classification of general purpose volume air compressors. The requirements are based on the compressors capacity, power input, type of drive, and other factors. The following parameters are used to determine the performance ratings: • Pressure • Temperature • Discharge Pressure • Capacity • Electrical Input Power Rating • Motor Efficiency • Power Input • Load/No-Load • Free Air Delivery • Thermal Expansion/Retraction • Noise Classification • Power Input/Free Air Delivery Ratio • Air Tightness • Temperature Rise • Leaks • Excessive Oil Lubrication • Motor Temperature All required tests must be completed in accordance with GB 3853-83 before the compressor can be certified and placed on the market. The test results must then be compared to the performance ratings to determine the compressors classification. Summary The GB 3853-83 standard provides the performance requirements and test methods for the evaluation and classification of general purpose volume air compressors. It applies only to general purpose volume air compressors that are self-contained and driven by an electric motor or spark ignition internal combustion engine. The standard is applicable to all types of general purpose volume air compressors that are used for a wide variety of purposes. The required tests must be completed in accordance with the standard in order for the compressor to be certified and placed on the market. The test results must then be compared to the performance ratings in order to determine the compressors classification.
