JB/T 50159-1999 This standard is a revision of ZB J01 009-87 "Energy Consumption Classification of Compressed Air Stations". This standard specifies the energy consumption levels of compressed air stations using reciprocating piston air compressors in mechanical industrial enterprises. Compressed air stations are classified into special, first, second and third grades according to the nominal exhaust volume of the first line in cubic meters and the average unit power consumption during the statistical period. Those that do not meet the third grade indicators are classified as out-of-grade. This standard was first issued in 1987.

This standard specifies the energy consumption level of compressed air stations for reciprocating plug-type air compressors used in micro-machinery enterprises. 2 Energy Consumption Classification
The compressed air station controls the nominal exhaust volume of each cubic meter and the average power consumption per unit during the statistical period is divided into special grade, first grade, second grade, blue grade, etc., which are not listed in the third grade indicators.
The power consumption of compressed air station is classified into different indicators in Table 1. Table

2 When the units in the compressed air station are divided into two or more units according to the nominal exhaust gas, the unit index with the largest unit shall be evaluated according to the nominal exhaust gas. 3 Calculation of power consumption per cubic meter of nominal exhaust volume of the compressed air station during the statistical period shall be calculated according to formula (1). In the formula: B——The average power consumption per cubic meter of nominal exhaust volume in the compressed air station shall be calculated according to formula (1). Power consumption, kw·h/kn: - Total power consumption of compressed air station during the statistical period, kw, h: ()
Total power consumption of compressed air station under working condition during the statistical period (one uses flow hole or flow spray to measure, the reading of the meter must be corrected and calculated according to the orifice design number to obtain V), kmt; - Exhaust gas temperature, is to convert the output V under working condition to the output V under suction condition, k: T,P

K-1.0: - average working pressure correction coefficient of the air station during the statistical period, according to the working status of this station, the annual average working pressure value can be found in Table 2
■ Compressed air total power stock: air The electricity consumption of compressed air, electricity consumption of short-circuit water, electricity consumption of ice, electricity consumption of lighting and other auxiliary equipment for the production of compressed air is the total output of lamps and lanterns at the two ends of the station during the statistical period. The total output metering point is at the appropriate place for the compressed air to eat. At the same time, there is a measuring point 3 for compressed air. The statistical status of the compressed air in the three working states of the compressed air station and the average power level are the data measured at the total outlet pipeline of the compressed air station.
