Common failures and maintenance of overload protectors for air-conditioning compressors

Overload protector of air conditioner compressor Installed between the active and passive sides of the power transmission, when an overload fault occurs (torque exceeds the set value), the torque limiter will separate, thereby effectively protecting the driving machinery and the load. Just like its name, the fundamental function of the overload protector is to protect the air-conditioning compressor.

Application of DCS system in anti-surge control system of air separation compressor

Keywords: DCS system, air separation compressor, anti-surge control system Preface 　　 The 6000m3/h air separation plant of Xilin Iron and Steel Company was completed in May 2001 by Hangzhou Oxygen Concentrator Group Company. The factory design was designed by Beijing Iron and Steel Design Institute. It was successfully put into operation on September 2, 2001, and it took more than half a year to run. It shows that the unit is operating stably, and all indicators have reached or exceeded the design value. The entire control system uses Honeywell’s TDC3000 and two GUS stations.

Application of synthetic compressor oil

At present, synthetic lubricants are widely used in the compressor field. Among them, oil-injected and oil-immersed rotary screw air compressors and large reciprocating compressors are one of the most used markets. For example, the sales volume of synthetic compressor oil in Western Europe was 6000t in the late 1980s, and it rose to 10000 in the early 1990s. The sales volume in the United States has exceeded 15,000 tons, and it is increasing at a rate of more than 10% per year.
