Systems and method for use of single mass flywheel alongside torsional vibration damper assembly for single acting reciprocating pump

A pump system comprising:

• a pump having an input shaft, the input shaft including an input flange;
• a driveshaft connected to the input flange of the input shaft of the pump;
• driving equipment including an output shaft having an output flange connected to the driveshaft and configured to rotate the driveshaft to rotate the input shaft of the pump therewith;
• and
• a plurality of vibration dampening assemblies comprising:
• one or more flywheels including a first flywheel operably connected to the input shaft and configured to rotate therewith, the one or more flywheels being configured to absorb a torque shock in the form of torque variance resulting from hydraulic fluid pulsation within the pump;
• and
• one or more torsional vibration dampers comprising a first torsional vibration damper operably connected to the input flange of the input shaft and a second torsional vibration damper connected to the output flange of the output shaft,
• the plurality of vibration dampening assemblies being configured to reduce high frequency/low amplitude and low frequency/high amplitude torsional vibrations generated by operation of the pump.

A method of manufacturing a flywheel for a pump system having a single acting reciprocating pump and driving equipment configured to cycle the pump, the method comprising:

• calculating a desired moment of inertia of the flywheel from kinetic energy “KE” of a torque variance within the pump system above a nominal torque of the pump system resulting from hydraulic fluid pulsation within the pump, calculating the desired moment of inertia of the flywheel comprising:
• calculating a first desired moment of inertia of a first flywheel from a first portion of the kinetic energy “KE” of the torque variance within the pump system resulting from hydraulic fluid pulsation within the pump;
• and
• calculating a second desired moment of inertia of a second flywheel from a second portion of the kinetic energy “KE” of the torque variance within the pump system resulting from hydraulic fluid pulsation within the pump, the first portion being greater than, lesser than, or equal to the second portion;
• sizing the flywheel to have the desired moment of inertia from the calculated moment of inertia, sizing the flywheel comprising sizing the first flywheel to have the first desired moment of inertia and sizing the second flywheel to have the second desired moment of inertia;
• and
• producing the flywheel for the pump system based on the sizing of the flywheel.
