STI Vibration has released the CMCP601R reciprocating compressor demonstration kit, designed to display vibration monitoring techniques used on reciprocating machinery.
The kit includes sensors and can also be equipped with accelerometers on the motor/gear, crosshead and cylinder end along with proximity probes in the distance piece for rod drop and rod runout.
A mounting bracket and machined flywheel notch are designed for a proximity probe key phasor or other types of a once-per-turn reference signal. Two shaft connecting rod holes allow the user to adjust the total stroke distance.
The battery powered DC motor features an adjustable speed up to 300 rpm. The cylinder is independently mounted on two vertical spring-loaded linear bearings and the alignment can be adjusted to demonstrate rod drop and rod run out.
The crosshead has upper and lower oil-infused bronze bearings and the piston rides on wear ring stock. The connecting rod has bronze bearings on both ends and connects the flywheel to the crosshead pin. Operators can adjust the stroke on the flywheel between 1 and 1.25 in. (25.4 and 31.75 mm).
