Spring support

Most vibrating conveyors are essentially directional-throw units which consist of a spring-supported horizontal pan vibrated by a direct-connected eccentric arm, rotating eccentric weights, an electromag-...

Provide adequate supports for equipment and pipes. Do not allow spring supports to be completely compressed. 

Turn the bowl body upside down. Screw out screws C26 and lift off spring support C25. 

Put the springs in their places on the operating slide and mount the spring support. - Tighten the screws of the support.

Tc, the spring stretched to achieve a pitch of 0.1 mm, and the sample applied by hypodermic syringe as a 50% by weight solution in methylene chloride. The viscoelastic response of the spring supported resin was then followed in a dry nitrogen atmosphere as a function of time. About 10 to 15 mg of resin per run was requi red.

The vibration pressing machine for the forming of specimens is shown in Figurel. This machine consists of a vibration top plate with an oil cyUnder and a bottom plate,both of which are fixed with 4 poles, and 4 top and bottom springs supported with 2 plates. The mechanical vibrator with a vibrating force of 300 kg is attached to the bottom of a vibration plate,and it consists essentially of 2 contra-rotating shafts with an out-of-balance weight at each end. The die set in vibration plates possesses a cavity of 30 mm in diameter and 90 mm in depth. The vibration and pressure were applied simultaneously by the top and the bottom punches. 

Select a support from a manufacturer s catalog. One spring support suitable for this application has a nominal rating of 2,900 pounds and a load-range of 2,030 to 4,060 pounds over its working deflection range, which tends to justify the short-cut method described herein. 

Note. Where it is desired to load the spring-supports to compensate for the liquid load, proceed as follows ... 

Adjust each constant support so that it lifts the addtional weight designated for it. The amount of this weight is usually arbitrarily set at 50% of the calculated liquid-load. This will make the prestress in the pipe about equal to the stress during operation and is about half of that which would result if the spring-support were adjusted for the full liquid-load.
