System for acquiring, measuring and checking the operating parameters of a reciprocating fluid machine

Abstract

The invention describes a validation system for a reciprocating fluid machine. The system comprises a base plate or foundation on which at least one frame of the reciprocating fluid machine is removably applied; a first shaft, rotatably coupled with the base plate, to activate the components of the frame; at least one system for generating loads, placed in operative connection with such components and put in rotation by a transmission system through at least one second shaft. The system for generating loads is able to simulate the loads generated by the working fluid on a cylinder of the reciprocating fluid machine.

1 . A validation system for a reciprocating fluid machine, the system comprising:
 a base plate on which at least one frame of said reciprocating fluid machine is removably applied;   a first shaft rotatably coupled with said base plate, to activate the components of said frame; and   at least one system for generating loads, placed in operative connection with said components of said frame and put in rotation by an actuation system, said system for generating loads being configured to simulate the loads generated by the working fluid on a cylinder of said reciprocating fluid machine.   
     
     
         2 . A system according to  claim 1 , wherein said reciprocating fluid machine is of the high performance type. 
     
     
         3 . A system according to  claim 1 , wherein said system for generating loads is of the mechanical, pneumatic, hydraulic or electric type. 
     
     
         4 . A system according to  claim 1 , wherein said system for generating loads further comprises at least one first elastic element placed in operative connection with said components of said frame and put in rotation by at least one eccentric, wherein said eccentric is put in rotation by at least one second shaft of said actuation system. 
     
     
         5 . A system according to  claim 4 , further comprising one or more preloading devices acting on said first elastic element, so as to adjust its preloading. 
     
     
         6 . A system according to  claim 4 , further comprising a yielding element interposed between said eccentric and said first elastic element to decrease the friction and promote the contact between said eccentric and said first elastic element. 
     
     
         7 . A system according to  claim 6 , further comprising a second elastic element associated with said eccentric and with said yielding element, so as to ensure the contact between said eccentric and said yielding element in any operative condition and to uncouple the rigidity of said first elastic element from that necessary to maintain the contact between said yielding element and said eccentric. 
     
     
         8 . A system according to  claim 7 , further comprising an adjustment element configured to adjust the preloading of said second elastic element, so as to further improve the contact between said eccentric and said yielding element. 
     
     
         9 . A system according to  claim 4 , wherein said first elastic element and said at least one eccentric are configured to be removed from said system to be replaced with elastic elements and/or with eccentrics of a different kind, in the case in which measurements and/or validations must be made on different reciprocating fluid machines or for different requirements. 
     
     
         10 . A system according to  claim 1 , wherein said actuation system is a mechanical system, comprising at least one actuation motor, and configured to at least partially return the energy absorbed in the outward stroke during the return stroke, decreasing the power that said actuation motor must deliver. 
     
     
         11 . A system according to  claim 10 , wherein said actuation system comprises a system of rigid connecting rods and of cranks actuated by said actuation motor. 
     
     
         12 . A system according to  claim 4 , further comprising one or more sensors configured to acquire and measure the operating parameters relative to said frame and to the assembly consisting of said first elastic element and said eccentric.
