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.

Single- and Dual-Blower Continuous Vacuum/Pressure Systems Page 9

Systems Used for Powders or Dusty Materials

Material lines on the vacuum side of the conveying system typically lead to a self­cleaning filter receiver, where material is separated from the airflow and passes through
a rotary airlock for transfer to the pressure side of the system. You can order the self­cleaning filter separately.

Systems Used to Convey Clean, Pelletized Material

Systems with solid state control units are used to convey clean, pelletized material. A
cyclone separator is furnished in the system to remove material from the vacuum side
airflow. A filter chamber is also furnished to clean the air entering the vacuum unit.

1-6 The Vacuum/Pressure Conveying System

Vacuum/pressure conveying systems are used to convey high volumes of powder or
pelletized material long distances from railcars into storage silos. They are available
with filters designed specifically for powder or other dusty materials.
Vacuum/pressure systems for powder are similar to pellet systems except they are
equipped with a filter receiver rather than a cyclone separator. This ensures separation
of the material and maximum dust control.

i.e. lockout/tagout.

2. Failure to maintain a clean and safe working environment.

Single- and Dual-Blower Continuous Vacuum/Pressure Systems

2-5 General Responsibility

NO MATTER WHO YOU ARE…

Safety is important. Owners, operators, and maintenance
personnel must realize that every day, safety is a vital aspect of
their jobs.

If your main concern is loss of productivity, remember this:

Production is always affected in a negative way following an
accident. The following are some of the reasons, which can affect

your production:

• Loss of a skilled operator (temporarily or permanently)

• Breakdown of shop morale

• Costly damage to equipment

• Down-time

An effective safety program is responsible and economically
sound.

Organize a safety committee or group, and hold regular meetings.
Promote this group from the management level. Through this
group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the
meetings.

Hold daily equipment inspections in addition to regular
maintenance checks. You will keep your equipment safe for
production and exhibit your commitment to safety.

Please read and use this manual as a guide to equipment safety.
This manual contains safety warnings throughout, specific to each
function and point of operation.

2-6 Operator Responsibility

The operator’s responsibility does not end with efficient
production. The operator usually has the most daily contact with
the conveying system and intimately knows its capabilities and
limitations.

Plant and personnel safety is sometimes forgotten in the desire to
meet incentive rates, or through a casual attitude toward machinery
formed over a period of months or years. Your employer probably
has established a set of safety rules in your workplace. Those
rules, this manual, or any other safety information will not keep
you from being injured while operating your equipment.

Single- and Dual-Blower Continuous Vacuum/Pressure Systems Page 15

REMEMBER:

ONLY YOU can make safety work for you by constantly thinking
about what is safe and what is not. It is often the “just once” that
an operator reaches into a conveying system to remove material
and it results in serious injury.

Learn and always use safe operation. Cooperate with co-workers
to promote safe practices. Immediately report any potentially
dangerous situation to your supervisor or appropriate person.

• NEVER place your hands or any part of your body in any

dangerous location.

• NEVER operate, service, or adjust the conveying system

without appropriate training and first reading and
understanding this manual.

• NEVER try to pull material out of the conveing system with

your hands while it is running!

• Before you start the conveying system check the following:

• Remove all tools from the conveying system;

• Be sure no objects (tools, nuts, bolts, clamps, bars)

are laying in the hopper area;

• If your conveying system has been inoperative or

unattended, check all settings before starting the unit.

• At the beginning of your shift and after breaks, verify

that the controls and other auxiliary equipment are
functioning properly.

• Keep all safety guards in place and in good repair.

NEVER attempt to bypass, modify, or remove safety
guards. Such alteration is not only unsafe, but will
void the warranty on your equipment.

• When changing control settings to perform a different

mode of operation, be sure selector switches are
correctly positioned. Locking selector switches
should only be adjusted by authorized personnel and
the keys removed after setting.

• Report the following occurrences IMMEDIATELY:

• unsafe operation or condition

• unusual conveying system action

• leakage

Page 16

• improper maintenance

Single- and Dual-Blower Continuous Vacuum/Pressure Systems

• NEVER stand or sit where you could slip or stumble

into the conveying system while working on it.

• DO NOT wear loose clothing or jewelry, which can

be caught while working on the conveying system. In
addition, cover or tie back long hair.

• Clean the conveying system and surrounding area DAILY, and

inspect the machine for loose, missing or broken parts.

• Shut off power to the conveying system when it is not in use.

Turn the switch to the OFF position, or unplug it from the
power source.

2-7 Maintenance Responsibility

Safety is essential to the good health of both operator and machine.
If you are a maintenance worker, you must make safety a priority
in order to effectively repair and maintain equipment.

BEFORE REMOVING, ADJUSTING, OR REPLACING
PARTS ON A MACHINE, REMEMBER TO DO THE
FOLLOWING:

• TURN OFF all air and electric supplies and all accessory

equipment at the machine.

• DISCONNECT AND LOCK OUT electrical and pneumatic

power, and attach warning tags to the disconnect switch and air
shutoff valve.

When you need to perform maintenance or repair work on the
conveying system above floor level, use a solid platform or a
hydraulic elevator. If there is a permanently installed catwalk on
your conveying system, use it. The work platform should have
secure footing and a place for tools and parts. DO NOT climb on
machines or work from ladders.

If you need to repair a large component, use appropriate handling
equipment. Before you use handling equipment (portable “A”
frames, electric boom trucks, fork trucks, overhead cranes) be sure
the load does not exceed the capacity of the handling equipment or
cause it to become unstable.

Carefully test the condition of lifting cables, chains, ropes, slings,
and hooks before using them to lift a load.

Be sure that all non-current carrying parts of electrical apparatus,
electrical component enclosures, and the conveying system frame

Single- and Dual-Blower Continuous Vacuum/Pressure Systems Page 17

2-8 Safety

2-8-1 Description and Objectives

This section includes information on safety devices and procedures that are
inherent to the Vacuum/Pressure Conveying System. This manual is not
intended to supersede or alter safety standards established by the user of this
equipment. Instead, the material contained in this section is recommended to
supplement these procedures in order to provide a safer working environment.

are correctly connected to earth ground with an electrical
conductor that complies with current codes. Install in accordance
with national and local codes, which apply.

When you have completed the repair or maintenance procedure,
check your work, remove your tools, rigging, and handling
equipment.

Do not restore power to the conveying system until all persons are
clear of the area. DO NOT start and run the conveying system
until you are sure all parts are functioning correctly.

BEFORE you turn the conveying system over to the operator for
production, verify all system enclosure panels, guards and safety
devices are in place and functioning properly.

At the completion of this section, the operator and maintenance personnel will
be able to:

• Identify and locate specific safety devices.

• Understand the proper use of the safety devices provided.

• Describe the function of the safety devices.

2-8-2 Safety Circuit Standards

Safety circuits used in industrial systems protect the operator and maintenance
personnel from dangerous energy. They also provide a means of locking out or
isolating the energy for servicing equipment.

Various agencies have contributed to the establishment of safety standards that
apply to the design and the manufacture of automated equipment. The
Occupational Safety and Health Administration (OSHA) and the Joint
Industrial Council (JIC) are just a few of the organizations that have joined
with the plastics industry to develop safety standards.

Page 18

Single- and Dual-Blower Continuous Vacuum/Pressure Systems

Every effort has been made to incorporate these standards into the design of the
Vacuum/Pressure Conveying System; however, it is the responsibility of the
personnel operating and maintaining the equipment to familiarize themselves
with the safety procedures and the proper use of any safety devices.

2-8-3 Fail Safe Operation

If a safety device or circuit should fail, the design must be such that the failure
causes a “Safe” condition. As an example, a safety switch must be a normally
open switch. The switch must be held closed with the device it is to protect. If
the switch fails, it will go to the open condition, tripping out the safety circuit.

At no time should the safety device fail and allow the operation to
continue. For example, if a safety switch is guarding a motor, and the safety

switch fails, the motor should not be able to run.

2-8-4 Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a circuit. The safety
devices that are utilized on this equipment are primarily concerned with the
pneumatics and electrical power disconnection, and the disabling of moving
parts that may need to be accessed during the normal operation of the machine.

Some of the safety devices utilize a manual activator. This is the method of
initiating the safety lock out. This may be in the form of a plug, disconnect
plug, lever or a handle. Within this lockable handle, there may be a location for
a padlock. Personnel servicing the equipment should place a padlock in the
lockout handle.

WARNING! Always disconnect and lockout all electrical power and pneumatic

(i.e. compressed air) sources prior to servicing or cleaning any
Vacuum/Pressure Conveying System. Failure to do so may result
in serious injury.
At no time must anyone remove the lockout or reconnect the twist
plug, other than the person who installed the lockout or who
unplugged the twist plug.

2-8-5 Lock-Outs, Plugs, and Other Safety Devices

The Vacuum/Pressure Conveying System utilizes several types of
safety devices.

The Line Cord Plug

This line cord plug allows the operator or maintenance personnel
to unplug the conveying system from its power source and tag it
out. This plug may be tagged with any number of approved

Single- and Dual-Blower Continuous Vacuum/Pressure Systems Page 19

WARNING!

electrical lockout tags. These tags are available at most electrical
supply stores.

Disconnect both of these items to ensure optimum maintenance
personnel safety when cleaning or servicing this equipment.
