Issues with three-speed and five-speed adjustment of reciprocating machines
Thread Content
In what cases is there 0-50-100 adjustment, and in what cases is there 0-25-50-75-100 adjustment?
The provision of three levels – 0-50%-100% – or five levels – 0-25%-50%-75%-100% – for adjustment is entirely due to process requirements. As for how to set the several adjustment levels, it depends on the unit; all double-acting cylinder reciprocators can be equipped with three flow rate adjustment levels of 0-50%-100%. Setting five levels of airflow adjustment depends on the number of compression stages and cylinders in the unit. For example, in the case of a 4M-type symmetrically balanced reciprocating machine, if it has only 2 compressors, five different adjustment levels can be achieved by using the inlet unloading valve switch ； But if it is three-stage compression, only three adjustment levels can be set.
The expert on the 2nd floor explained it in great detail; I’ve learned a lot.
It features a stepless gas flow control system that allows adjustment between 30% and 100%, offering good adaptability and energy efficiency. A complete set of such systems is in use in the workshop, and they have been operating for over 2 years now
