Esquema estructural y aplicación

Rotary valves ( also known as rotary airlocks or rotary feeders ) are commonly used in industrial and agricultural applications as a component in a bulk or specialty material handing system. Rotary valves are primarily used for discharge of bulk solid material from hoppers/bins, receivers and cyclones into a pressure or vacuum-driven pneumatic conveying system. Components of a rotary valve include a rotor, shaft housing, head plates and packing seals and bearings. Rotors have large vanes cast or welded on and are typically driven by small internal combustion engines or electric motors.

Rotary valves have wide application in industry wherever dry free-flowing powers, granules, crystals or pellets are used. Typical materials including cement, ore, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc.

 Troubleshooting

Symptom	Possible cause	Solution
Rotor does not               rotate	No power to motor	Check breaker Check motor heaters                  Check motor starter
	Wrong Connection type	Correct the connection type to “△”
	Voltage or frequency much less                         than design	Improve power supply
	Rotor is jammed	Inspect rotor and remove object
	Chain is broken or has come off	Remove guard and inspect drive
	Faulty motor  or gear reducer	Remove chain and  run motor with no load
Excessive noise	Bearings need grease	Grease bearing, replace if necessary
	Rotor has shifted	Inspect rotor and realign
	Rotor is rubbing end housing	alignment clearance
	Drive chain is rubbing on guard	Reposition chain guard or sprockets and chain
Excessive air  leakage through airlock	Worn rotor wiper	Inspect and replace
Motor burn, shaft break	Rotary valve too small	Change bigger valve
