KINETICS 1" and 2" Deflection Isolation Hangers Model SRH

Transcription

1 Polyester Powder Coated Bracket and Sprg Coil Self-Centerg Cap Patent No. 5,6,426 Application Ketics Model SRH hangers are used to isolate suspended sources of both noise and vibration. Suspended mechanical equipment such as -le fans, cabet fans, and pipg and ductwork close proximity to mechanical equipment are typical uses of Model SRH hangers featurg the patented No-Short self-centerg cap. Ketics mimum recoendation for the placement of sprg hangers is that they be stalled on all pipg the equipment room and on the first 50' (15 m) for pipg that extends outside of the equipment room. For typical stallations, the three sprg hangers closest to the equipment should have equal deflection to the equipment isolators. The remag sprg hangers should have a mimum deflection of 1" ( ). In noise sensitive areas, the pipe hangers selected should have the same deflection as that specified for the equipment isolation and all pipg the buildg should be isolated. High sound transmission loss ceilg systems can be isolated by the use of SRH hangers the ceilg suspension system. Standard SRH hangers are shipped fully assembled and ready for stallation threaded metal rod suspension systems. Model SRH hangers are available a wide range of load and static deflection selections and can be provided with labor-savg accessories for adaption to wire or strap suspension systems, and sprg may be preloaded for ease erectg pipg at a fixed elevation. KINETICS 1" and 2" Deflection Isolation Hangers Model SRH Description Ketics SRH vibration isolation hangers consist of free-standg, large diameter, laterally stable steel sprgs series with an elastomer-shear sert, assembled to a stamped or welded hanger bracket. To assure stability, the sprg element has a mimum lateral sprg stiffness of 1.0 times the rated vertical stiffness. Hangers with properly deflected coils will allow a support rod misalignment through a 30 arc without short circuitg. Isolation brackets will carry a 500% overload without failure. Hangers are available deflections from 1.20" to 2.40" (30 to 61 ), and capacities from 35 to 3500 lbs. ( to 1588 kg). Model SRH hangers are superior to hangers which corporate only sprgs, which can transmit noise through the all metal construction, and hangers which corporate only pads, which can transmit low frequency vibration. Ketics Model SRH hangers are recoended for the isolation of vibration produced by suspended mechanical equipment, low-speed suspended fans, transformers, ductwork, pipg, etc. How the self centerg no short cap works: Indexed steps sprg cap correspond to standard washer diameters for the appropriate rod diameter. The washer and rod stay centered the cap.

5 KINETICS 4" Deflection Isolation Hangers Model SRH Application Ketics SRH hangers are used to isolate suspended sources of both audible and audible noise and vibration. Suspended mechanical equipment such as -le fans, cabet fans, and pipg and ductwork close proximity to mechanical equipment are typical uses of Model SRH hangers. Ketics mimum recoendation for the placement of sprg hangers is that they be stalled on all pipg the equipment room and on the first 50 ft (15 m) for pipg that extends outside of the equipment room. For typical stallations, the three sprg hangers closest to the equipment should have equal deflection to the equipment isolators. The remag sprg hangers should have a mimum deflection of 1. ( ). In noise sensitive areas, the pipe hangers selected should have the same deflection as that specified for the equipment isolation and all pipg the buildg should be isolated.

Description Ketics SRH Vibration Isolation hangers consist of free-standg, large diameter, laterally stabile steel sprgs series with an elastomer-shear sert, assembled to a welded hanger bracket. Hangers corporate a high deflection, color-coded sprg element with load transfer plate and a 0.4. (10 ) deflection elastomeric isolator complete with load transfer plate. To assure stability, the sprg element has a mimum lateral sprg stiffness of 1.0 times the rated vertical stiffness. Sprgs are polyester powder coated, with a 1000 hour salt spray ratg per ASTM B-117. Hangers will allow a support rod misalignment through a 30 arc without short circuitg. Isolation brackets will carry a 500% overload without failure. Hangers are available deflections from to (104 to 112 ), and capacities from 100 to 3850 lbs. (46 to 17 kg). Model SRH hangers are superior to hangers which corporate a sprg only, which will transmit noise through the all-metal construction, and hangers which corporate noise stop pads only, which will transmit low frequency vibration that a sprg can isolate. Ketics Model SRH combation hangers are recoended for the isolation of vibration produced by suspended mechanical equipment, low speed suspended fans, transformers, ductwork, pipg, etc.
