Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method of detecting improper opening of a multiple suction reciprocating compressor suction valve of a reciprocating compressor, the reciprocating compressor comprising: at least one compression mechanism comprising at least one compression cylinder, at least one piston configured for reciprocating linear movement inside the cylinder, at least one “valve-port” set fluidly coupled to the compression cylinder integrated by at least one suction port, at least one actuating suction valve cooperating with its respective suction port, and at least one electrical magnetic generator element configured to interact selectively with the suction valve; an electrical engine cooperating with said piston; at least one electronic processing core; and at least one sensor configured to measure at least one variable proportional to torque of said electrical engine; the method characterized by monitoring, by the electronic processing core, the at least one variable proportional to torque of said electrical engine measured by the sensor; wherein the detection of improper opening of the suction valve is made by the detection of at least one peak of said variable proportional to torque of said electrical engine during power of the electromagnetic field generator element. 2. Method, of claim 1 , wherein the variable proportional to torque of said electrical engine comprises the electrical current that runs by a coil of the electrical engine. 3. Method, of claim 1 , wherein the variable proportional to torque of said electrical engine comprises the electrical power of the electrical engine. 4. Method, of claim 1 , wherein the variable proportional to torque of said electrical engine monitored comprises the speed of the engine resulting from the improper opening of suction valve.
