Airam Press Co. LTD. is a produces of pneumatic presses with a unique air tube mechanism for the stamping, blanking, roll forming and die cutting industries. Their customers reported a problem of the press energy being transmitted to the floor with vibration being felt through the plant.
MBI Building was responsible for installing a Marley 450 ton cooling towers on the roof of the building located in a nearby Corporate Research Park. AirLoc B4 pads were recommended with low profile (2 inches height) and a natural frequency of around 9 Hz (cycles per second), which provides excellent isolation for the variable speed drive tower cooling fans.
Dies for stamping presses and tandem press lines are generally maintained in an area close to the machines where they are installed, and existing floors where they sit are typically concrete or wood block construction. The use of AirLoc 900 series pads solves the problem of damaged tools and floors when heavy dies are moved and accidentally overturned or dropped.
Late last year AirLoc worked closely with Lane Systems & Supply Company to help solve a noise and vibration problem on pumps at a paper mill in Maine. The problem was severe enough to limit the speed the pumps could run at. By incorporating AirLoc high-damp pad material directly under the pumps and the pump stands mounting feet, along with isolation washers, the vibration levels were reduced dramatically.
J.P.L. Compressor Service uses AirLoc low stiffness, 32 pad to insure that his equipment will not transmit noise into buildings, and attached structures. Below is shown a recent installation of rooftop cooling fans with the AirLoc 32 pads cut to size and used to support the equipment and isolate the vibration/noise from the support structure.
AirLoc was asked to provide a pad isolation system for an installation where a lube oil pump unit was already installed and modifications had to be minimized. Severe vibration inputs were being generated by a large motor driven cooling fan mounted on the same foundation as the lube oil pump in a new power plant facility.
