AEC Continuous Vacuum/Pressure Conveying Systems - Manual (Page 10)

Single- and Dual-Blower Continuous Vacuum/Pressure Systems Page 9
1 General Information
1-1 Models Covered
AEC single vacuum pressure (SVP) systems have a single blower/motor combination
used for vacuum and pressure conveying. Continuous vacuum pump/continuous
pressure pump (CVP/ CPP) systems have dual blower/motor combinations and have a
dedicated pump for vacuum, as well as one for pressure, conveying.
In this manual, vacuum and pressure units are listed separately to maintain common
terminology. Keep in mind, however, that SVP systems employ one blower for
vacuum and pressure conveying.
AEC single-blower vacuum/pressure systems and dual-blower continuous vacuum
and/or pressure systems are offered in numerous configurations to meet your specific
requirements. All systems feature:
• Vacuum unit
• Pressure unit
• Remote-mount control unit
• Blow-through adapter with stand
• Rotary airlock
• Shear protector (pellet valve) – pellet systems only
• Self-cleaning filters or cyclone separators
A variety of components can be combined in a vacuum/pressure conveying system to
meet specific conveying requirements. This manual offers a general overview of
systems using AEC power units. Training in the proper operation and maintenance of
an AEC-designed system is available from the Service Department of AEC, Inc.
1-2 Equipment Function
Single-blower vacuum/pressure systems and dual-blower continuous vacuum and/or
pressure systems are designed to convey large quantities of free flowing pelletized,
powdered, or granular material over long distances. A typical application is unloading a
railcar to a storage silo. In such an application, material is drawn from the source by the
vacuum blower to a cyclone chamber or continuous cleaning filter receiver, where
conveying air and material are separated. The material passes through a rotary airlock
valve to a blowthrough adapter, where the pressure unit conveys material to the storage
silo.
