I purchase a part cast from alloy 356 that is received with the T5 temper. The part is approximately 30" in diameter, 10" deep, and 2" thick (hollow in the center). On the inside surface tapped holes are machined for nozzles. The tapped holes intersect the as-cast water channels on the...
I am considering the use of a vibration switch on a piece of equipment we manufacture to automatically shut-down when vibration becomes excessive. The equipment has a 25 hp motor with a fan blade direct mounted to the shaft spinning at 3600 RPM. The equipment is used year round therefore ice...

The motor runs at full speed at 60Hz. No VFD is used. Ten Failed bearings were sent to the manufacturer for analysis with the following observations made by their engineers:
Ineffective lubrication
Insufficient lubrication
Unsuitable lubrication
Excessive thrust load...

A piece of equipment that we sell continues to fail bearings faster than would be considered normal (1 month or less running 24/7). The unit has a 20" propeller that spins at 3600 rpm. The propeller is used to fracture water introduced by a spray manifold at 100 psi and a maximum flow rate of...
