Abstract
A method and apparatus for analyzing the operating condition of a machine, such as a reciprocating compressor (10), is provided. The method comprises testing for fluid flow across the closed suction and discharge valves (30-33), as well as leakage across the piston (16), when the machine is in a non-operating condition. The test apparatus may be removable attached externally to the machine by connection to the Kiene head end indicator cock (22) and the crank end indicator cock (24) or the apparatus may be built in internally of the machine.
Claims44
A machine, comprising
- a piston mounted for reciprocating movement in a cylinder;
- a pressure activated valve movable between an open position and a closed position for controlling fluid flow between the interior and the exterior of the cylinder;
- and
- means operative when the valve is in the closed position for measuring fluid flow across the valve.
A machine, comprising:
- a piston mounted for reciprocating movement in a cylinder;
- a pressure activated valve movable between an open position and a closed position for controlling fluid flow between the interior and the exterior of the cylinder;
- and
- means operative when the valve is in the closed position for measuring fluid flow from the interior to the exterior of the cylinder.
A reciprocating compressor, comprising:
- a cylinder having a head end and a crank end;
- a piston mounted for reciprocating movement in the cylinder between the head end and the crank end;
- a suction bottle connected to the interior of the cylinder through a suction manifold;
- a discharge bottle connected to the interior of the cylinder through a discharge manifold;
- a head end suction valve and a crank end suction valve for the inflow of fluid into the cylinder;
- a head end discharge valve and a crank end discharge valve for the outflow of fluid from the cylinder;
- and
- means operative when said suction valves and said discharge valves are closed for measuring fluid flow from the interior to the exterior of the cylinder.
A method of analyzing the operating condition of a machine which has a piston mounted for reciprocating movement in a cylinder and a pressure activated valve movable between an open position and a closed position for controlling fluid flow between the interior and the exterior of the cylinder, which method comprises the steps of placing the machine in an inoperative condition and measuring fluid flow across the valve with the valve in the closed position.
