The compressors and pumps frequently use crank and connecting rod mechanisms. The force and mass oscillations cause vibrations in the units.
The Set of Crank Mechanism, "MDU-SCM", allows to adjust the stroke, mass compensation and bearing clearance, as well as the speed, to simulate vibrations.
The load is exerted by springs.
When you want to simulate the force obtained by a gas compression, a higher torque is required, for which it is recommended to use the Set of Belt Drive, "MDU-SBD", or the Set to Study Damage in Gears, "MDU-SSDG".
