IV. VACUUM RECOVERY SYSTEM SPECIFICATIONS
The PD2100D vacuum recovery system is provided for recovery of abrasive from a blast chamber.
The components of the vacuum system are as follows:
A. POSITIVE DISPLACEMENT VACUUM PUMP UNIT
The Roots Positive Displacement vacuum pump, Model ??????(serial #??????), is a direct drive unit utilizing a
flexible coupling connected to a diesel engine at approximately 2300 rpm. At this rpm, the unit draws approximately 2100 SCFM of air (free air capacity).
At 21", 85 brake horsepower it draws approximately 1100 CFM.
This vacuum pump consumes approximately 100 HP and provides an efficient and economical means to provide recovery of spent
abrasive. The unit is capable of pulling 27" HG vacuum with a plugged hose (zero airflow).
A vacuum instrumentation package is included with the unit.
The PD vacuum unit is capable of recovering six (6) to eight (8) tons of abrasive per hour with one hundred (100) feet of 4"
diameter vacuum hose in the horizontal position.
B. DIESEL ENGINE
A John Deere diesel engine, Model ??????, (serial # ) with ????? PTO, Model (serial
# ???) is provided to drive the vacuum pump.
All manufacturer’s instructions and recommendations must be followed.
Special care is required during the“break-in” period.
C. SILENCERS
An inlet, exhaust and bleed air silencer package has been provided by ??????? to give the best sound reduction at many
frequencies. ????? is the industry leader in sound reduction of positive displacement vacuum pumps.
See manufacturer’s literature following this page for complete information.
D. SAFETY FILTER
A vacuum rated safety filter is provided to prevent carry-over of dust from the reclaim system to the vacuum pump. It is a single cartridge type dust filter with 2100 CFM capacity, intended to protect the vacuum pump in the case of a seal or filter failure in the VDC-4 vacuum dust collector. The safety filter housing will operate under a negative pressure condition of 29” HG.
The safety filter has a Magnehelic gauge to indicate when there is a carry-over problem from the VDC-4. With the PD2100-D connected to a vacuum collection tank or hopper and vacuum recovery hose, a reading of 10 – 12 inches WC would indicate a possible problem and the equipment should be inspected. A
reading of 0 during operation of the equipment is indication of a definite problem and the equipment should be shut down immediately.
The safety filter may well be damaged and need to be replaced.
The safety filter is the LAST line of defense for the vacuum pump. Replacement cost of a vacuum pump constitutes 50% of the total price of the equipment.
Protect your investment by watching the Magnehelic gauge and changing the safety filter when necessary.
E. VDC-4 VACUUM DUST COLLECTOR
The Cartridge Dust Collector is an aspirated cartridge, self-cleaning unit designed to remove airborne dust coming from the customer-supplied collection tank or hopper. It is not intended to collect abrasive. The abrasive should be vacuumed up into a collection tank.
NOTE: It is VERY IMPORTANT that the hopper not be allowed to overfill as that may result in carryover damaging the filters,
the dust collector housing or even destruction of the vacuum pump.
The VDC-4 is designed for operation under vacuum up to a maximum of 29" Hg. The incoming air passes from the outside to the inside of the cartridges;
enters the upper or clean air plenum; and exits through the clean air outlet. Cartridges are cleaned in sequence by back flushing with air from the clean air plenum.
A short burst of compressed air creates this momentary airflow reversal which is limited to only one (1) cartridge at a time.
Therefore, the unit continues to collect dust while its cartridges are being cleaned.
A solid-state Sequential Controller located in the control box determines the order in which the solenoid valves will be operated; the length of time that each valve will be opened; and the time interval between such valve openings. The solid state controller operates continuously whenever electrical power is supplied to it.
The dust collector is equipped with a regulator/filter and a pressure gauge. This filter/regulator is intended to remove only minor amounts of water and dirt.
Periodic draining of condensate from the air reservoir (manifold) and regulator/filter is recommended.
NOTE: It is very important that only clean, dry air be supplied to the dust collector. Wet air will drastically shorten the life of the filters.
UTILITIES SUPPLY AND CONNECTION
Recommended operating pressure is 90 to 105 PSIG.
The total usage of compressed air is a variable that is dependent upon the amount and type of dust being collected; the size of the dust collector; the condition of the filter cartridges; the set points of the RATE and DURATION timers in the Sequential Controller and the pressure in the air reservoir (manifold).
When the DURATION timer is set at its normally recommended time of 0.1 second, the approximate amount of air usage will be as follows:
Number of Air Usage per Pulse Cubic Feet Free air
Cartridges (when RATE timer is set at 60 seconds) 4 0.9
The air usage rate in CFM of free air depends upon the setting of the RATE timer. If the timer is set at twenty (20) seconds,
the rate will be three (3) times the values above, etc.
OPERATION AND MAINTENANCE
The dust collector requires only a weekly visual check to make sure that nothing has gone wrong and replacement of the cartridges when necessary.
NOTE: DO NOT use the hopper as a receptacle for the temporary storage of the collected dust. It is merely a large funnel from which
the dust must be removed on a continual basis. If dust is allowed to collect in the hopper, it will tend to re-entrain in the air stream, re-depositing on the
cartridges and shortening their life If the dust being collected is sticky or has long fibers in it, check the hopper every two (2) hours,
or as required, to make sure that the dust has not bridged across and plugged the outlet.
After each dumping of dust from the dust collector, make sure the butterfly valve is completely closed to the last notch on the handle indicator.
FILTER REPLACEMENT
When the pressure drop across the cartridges is between six (6) to eight (8) inches on the Magnehelic gauge, cartridges should be replaced as described in the following instructions. Prior to installing new filters, verify that the cartridges have not been damaged during shipment, storage or transporting of the unit.
Shut off electrical power to the dust collector.
The cartridges are removed and installed through the main access door of the Dust Collector. Remove the bolts securing the door and
open the door. Remove the top nut and loosen the second, locking nut, on the top of the dust collector. This will allow the threaded rod
(adjustment rod) to lower to a position where the top of the threaded rod is flush with the top of the bottom nut. This will allow the four (4) legged filter
platform to turn like a “Lazy Susan”.
NOTE: Do not remove the second nut completely or the rod will drop out.
Remove and reinstall the filters on this turn-table platform. Once all filters are in place, line the filters up with the capture rings
located in the top of the dirty air chamber of the dust collector. Slowly tighten the nut on the top of the dust collector, which will raise
the filters until they are sealed against the top of the dirty air chamber.
IMPORTANT: While tightening the nut, make sure the filters are rising straight and that they are
all lined up correctly in their appropriate capture ring. Tighten the nut until the filters are tight and will not slide or
move. Be careful not to over tighten the filters as this may cause the filters to collapse.
Once the desired tightness (approximately forty-five (45) ft. lbs. of torque) is achieved,
install the second nut and tighten it down against the first nut to act as a jam nut so the adjustment rod can not loosen.
Close and fasten the access door and pre-coat the filters as described below. Pre-coating the cartridges with a suitable filter aid material will both
increase efficiency and increase cartridge life. Filters are expensive. The cost of pre-coat material could save many dollars in filter
costs. A simple feeder and qualified pre-coat material are available from SAFE Systems.
With the controls set to pulse continuously at five (5) second intervals, feed five (5) to ten (10)
pounds of filter pre-coat material per cartridge through an open hopper discharge device or into the inlet duct. Repeat as frequently as desired.
Reset the RATE (OFF) timer to sixty (60) seconds. Check the DURATION (ON) timer. It should be set for 0.1 second.
Close the door of the Control Box. Tighten all door clamps.
SAFETY NOTES:
The manufacturer relies on the skills and expertise of its customer, and any consulting engineers and/or installing contractor hired by that customer,
to properly design and operate the dust collection system of which the dust collector is a part. Please take precautions as required to minimize
the inherent risk of dust combustion, fires and explosions. Be sure to read this manual thoroughly
and comply with all precautionary statements relative to worker safety.
Take special care whenever the door of the control box is open. The full line voltage can appear from
any electrical point on the circuit board to the metal enclosure or to ground.
Do not collect combustible materials along with dust from ferrous grinding or other spark generating operations.
Sparks caused by such operations may start a fire in the combustible dust.
Under no circumstances should anyone be allowed to discard a lighted cigarette or other burning
material into an inlet hood or ducting of the dust collection system.
It is the responsibility of the user to comply with all applicable national or local fire and safety codes.
The dust collector does not contain explosion vents except on special order. Refer to NFPA 68 "Guide for Explosion Venting" or your insurance
underwriter for recommendations regarding the sizing and installation of explosion vents.
