Abstract
A method for detecting an improper opening of a multiple suction reciprocating compressor suction valve of a reciprocating compressor includes monitoring, by an electronic processing core, a variable proportional to torque of an electrical engine that cooperates with a piston of the reciprocating compressor, the variable being measured by a sensor. A detection of the improper opening of the suction valve is made by a detection of at least one peak of the variable proportional to torque of the electrical engine during power of the electromagnetic field generator element.
