1) arranged compressors and ancillary equipment shall meet the requirements of the manufacturer; (2) the compressor should be arranged in the vicinity of the device is pumped, the ancillary equipment should be close to the unit layout; (3) combustible gas compressors should be arranged meet the following requirements: 1) and fire equipment, non-explosion-proof electrical equipment spacing, and should comply with national standards, "the explosion and fire hazard electrical installation design specifications" provisions GB50028 and "fire protection design of petrochemical enterprises" GB50160; and 2) should be open or semi-open layout arrangement. In cold or sandy areas can be arranged in the plant; 3) single drive power is equal to or greater than the CPI 150kw gas compressor plant, a building should not be shared with other A, B, C class room; the top of the compressor, not furnished A, B, C liquid equipment, but occupied high oil tank subject to this limit. (4) single compressor arrangement, when a high base, should be set according to the operating platform; when many ancillary equipment, should be arranged in the purchase of two air compressors, in addition to the acquisition costs, how to save the high electricity costs? How to prolong the life of the compressor? How stable gas supply pressure? and how to reduce ambient noise and pollution? also an issue of concern to the user, how to choose the correct initial purchase compressor plays a key factor. First, you must understand the selection of air compressors the following: 1. The use of compressed air 2, the minimum working pressure and 3, tip and off-peak gas demand required amount of compressed air per minute. If using a pressure difference between the highest and lowest reaches 3bar, it must be considered "high voltage shunt", and then tip the burden of change from peak to choose different models of air compressors, such as "baseload" using centrifugal (single> 75CMM) or spiral (single <60CMM): "Change of load," using high-pressure air machine to cope with the large storage barrels. 4, depending on the air quality with the selection and configuration of different forms and levels of precision filter dryer and, over a good quality waste energy, the impact of insufficient quality manufacturing process, must be carefully considered. 5, air machine control technology advances, "multi-unit chain", "Frequency shift" and "remote monitoring" and other technology, can effectively inhibit the BOV and centrifugal load spiral waste (25-40% electricity savings) empty presses, machine capacity and reduce equipment investment (15-30%) Cottle air compressor, air pressure stable (plus or minus 0.1bar). 6, the operation efficiency is not only a nominal amount of wind-powered and compare the catalog, focusing on the actual "performance curve" and "air volume per horsepower." 7, consider the size of the floor space to install Qin Wei air compressors, ventilation, noise isolation, waste heat, waste recycling and so lead sound energy use. In addition, "centralized" than "distributed" has lower installation, maintenance and control costs, but also can reduce the peripherals.
