Pickling for scale of compressor cooler in primary filling station

Tubular cooler is an important part of reciprocating compressor. Scale on the cooling pipes will reduce the cooling efficiency and gas supply so as to affect performance of the compressor. Taking compressor coolers in some primary filling station as an example, sulfamic acid and citric acid-based organic acid mixed solutions are used to clean coolers, which can reduce material corrosion of cooling system components in addition to effectively removing the scale. For cleaning of the cylinder, lubricating oil cooling pipe and other parts, the reverse and sectional cleaning method is proposed to solve the problem of difficult cleaning due to the complexity of cooling lines. In order to reduce failure rate, routine maintenance considerations of cooling systems are summarized, which can provide references to the operation and management of compressor cooling systems.
