MONITORING SYSTEM FOR RECIPROCATING PUMPS

摘要

A reciprocating pump assembly includes a pump housing that houses a crankshaft. Pistons are mechanically connected to the crankshaft for pumping fluid through cylinders. Each cylinder has a fluid inlet and a fluid outlet. The pump also has a monitoring housing connected to the reciprocating pump. Within the monitoring housing is a computer with memory. Pressure sensor assemblies sense a pressure value of a fluid within the pump, and are in electrical communication with the memory. An accelerometer positioned on the pump measures vibrations of the pump and is also in electrical communication with the memory for storage of sensed vibrations or displacements during operations. A proximity sensor in electrical communication with the memory is located within the pump housing to determine the rotational velocity of the crankshaft.
