Mass unbalance in a rotating system often produces excessive synchronous forces that reduce the life span of various mechanical elements. Unbalance is basically very simple case caused by an asymmetry in the rotating element that results in an offset between the shaft centerline and center of mass. Asymmetry can be an off-center weight distribution, or it can be a thermal mechanism that produces uneven heating and bowing of the rotor, or it can be an electrical effect that produces uneven magnetic field.

Machinery can be idle from intermittent use, stand-by (redundancy), storage for spare parts, or for temporary decommissioning. This article looks at practices that protect equipment characterized as decommissioned, short-term storage or storage of stand-by capacity.

For many applications, a REFRIGERATED COMPRESSED AIR DRYER is one of your best solutions to getting the moisture out of your compressed air system. Look for these symptoms to tell when you need a Refrigerated Compressed Air Dryer…

There has always been a debate on whether jack screws should remain tight against the side of the machine case after the machine has been moved into position or to back off the screws, so they do not touch. Should jack screws be tight or backed off? The answer is yes and no. In some situations you should leave the bolts tight against the machine and in other situations, it may be better to back off the jack screws.

“What’s the system’s normal operating temperature? What’s the system’s usual operating pressure range?” If you can’t answer these two basic questions about the vital signs of your hydraulic equipment I strongly recommend you make the effort to get to know your hydraulic equipment better. The information is easy to collect and can give valuable insight to the health of your hydraulic equipment.
