SETTING UP YOUR UNIT CAMCORP dust collectors are shipped in various states of assembly depending on the size and configuration of the unit. Before attempting to move the dust collector or any of its sections, review both the certified general assembly drawing supplied with your unit and the rigging and lifting guidelines included in this manual.
Platform Installation: The platform, ladder, handrail, and bracing are to be installed as shown on the special platform detail provided. Use the part ID’s to locate the parts in the proper location. Explosion Vents (where applicable): 1. Figure 6 – The explosion vents are attached with a minimum of standard steel fasteners for shipment. THESE MUST BE REMOVED and the PVC Bolts installed that are included in the shipment. Extreme care should be exercised when installing the PVC Bolts as they are very fragile.
Electrical: A 120-volt, 60-Hertz, 1-Amp circuit is required to operate the dust collector’s Solid State Timer. A 230/460V 3-phase circuit is required to run the Pulse Arm drive motor and the Cleaning Air PD (Positive Displacement) pump motor. Note: The Adjustable Timer needs to be mounting were the Pressure Gauge on the PD Pump is visible. 5-3 CAMCORP, INC.
Gauges: Check the pressure differential gauge to make sure that the high-pressure tap is connected below the tube sheet and the low-pressure tap is connected above the tube sheet. Verify that the gauge have been zeroed prior to connection when it is in its permanent mounting position. Cleaning Air PD Pump: The PD Pump must be install at the base of the filter to accommodate installation of the Air Supply line. Securely anchor in permanent location.
TOP LOAD BAG AND CAGE INSTALLATION 1. Inspect the cage for any signs of damage, warping, bent wires, or missing welds. 2. Inspect the filter bag for any signs of mold, mildew, ripped seams, or holes. 3. Lower the closed end of the bag through the hole in the tube sheet. 4. With your hands, “kidney shape” the snap band bag top in order to fit and align it within the tube sheet hole. 5. Fit the groove of the snap band to the I.D. of the tube sheet hole and allow it to expand and audibly snap into place.
START-UP CHECKLIST 1. Installation Make sure the unit is secured to grade. The ladder(s) and platform(s) must be tightened and set up according to OSHA requirements. Ducting and piping must be secured and routed out of the way of traffic whenever possible to avoid injury. Ducting must also be free of all debris including moisture. 2. Interior of the dirty air plenum A. Make sure that the filter bag assemblies hang straight and the bottoms do not touch each other or any part of the collector interior.
5. Exterior of dust collector A. Access doors, inspection ports, and relief vents should seat effectively to prevent leakage. B. All bolts must be properly tightened. C. Operate any equipment connected to the dust discharge of the dust collector. Check the rotation of any motor driven equipment such as rotary airlocks, horizontal unloading valves, live bottom bin activators, and screw conveyors. Check slide gates and butterfly valves for binding. 6.
START-UP DUST CONTROL SYSTEMS 1. Fan or blower system A. Start the fan or blower and check rotation. B. Check dust pickup points for proper suction; balance airflow in individual ducts. C. Check for air leakage at all flanged connections. 2. Equipment start-up sequence A. Start the pulse arm drive motor (direction of rotation is not critical). B. Start the PD pump motor and check rotation. C. Adjust timer Off-time by watching pressure gauge on PD pump. The pressure in the tank should peak between 7-8 PSI.
H. Observe the manometer or magnahelic differential pressure gauge reading. As the new filter bags become coated with dust, the efficiency of the filtering action increases, and the differential pressure across the filter bags will also increase. Slowly bring the collector to full load and note the final pressure drop across the filter bags. Never allow the pressure drop across the filter bags to exceed 17” w.g. maximum or filter bags may collapse. I.
SHUT-DOWN PROCEDURES 1. Dust control systems Reverse start-up procedure, shut down fan, then after 5 or 10 minute delay, shut down the PD pump and pulse arm drive motor. 2. Pneumatic systems Reverse start-up procedure, shut down fan, then after 5 or 10 minute delay, shut down the reverse air fan and sweep arm drive motor. 9-1 CAMCORP, INC.
TROUBLESHOOTING THE DUST COLLECTOR I. Excessive pressure drop across filter bags The differential pressure gauge or manometer on your dust collector should read 6” w.g. or less. Higher readings and/or steadily increasing readings are an indication that the main airflow through the dust collector may be restricted, and a potential process problem such as poor suction at duct pickup points may exist. In extreme cases (over 17” w.g.) filter bags will be damaged. Check the following: A.
TROUBLESHOOTING THE DUST COLLECTOR (continued) Visually inspect the bags for heavy caking; if caking is evident, see the note below and take the necessary action to clean the bags. Next, measure the main airflow with a pitot tube or equivalent devise and compare with the original volume for which the unit was designed. If the flow is too high, cut back the main fan to prevent a recurrence of the problem. 3.
TROUBLESHOOTING THE DUST COLLECTOR (continued) II. Extremely Low Pressure Drop A. Pressure Gauge Check the differential pressure gauge or manometer and the tubing leading to the dust collector as in I-A of this section. B. Holes in Filter Bags or Bags Incorrectly Installed. Inspect the filter bags for holes, rips, tears, or excessive wear. Make sure that the filter bags were installed correctly according to the “Bag & Cage Installation” section. C.
TROUBLESHOOTING THE DUST COLLECTOR (continued) B. Residual Dust If dust has gotten into the clean air plenum because of a dropped or torn bag, hole in tube sheet, etc., the pulse air may stir up the dust and allow it to escape into the clean air exhaust. Residual dust may also be driven down inside the filter bags by the pulse air; if the filter bags are filled with several inches of dust, clean both the clean air plenum and the filter bags to avoid further problems. V.
TROUBLESHOOTING THE CLEANING MECHANISM 1. Diaphragm Valve – Pulsing Failure. The Diaphragm assembly consists of (3) components. The main diaphragm valve, the secondary diaphragm valve, and the solenoid valve. Troubleshooting recommendations as follows: A. Main Diaphragm and Secondary Diaphragm: 1. Diaphragm Valve Bleeding Air – Disassemble and inspect both diaphragms for ruptured valves or air bleed holes are restricted. (Reference attached manual) Replace with a repair kit if necessary. 2.
3. Positive Displacement (PD) Pump - Following is a list of possible Symptoms and Troubleshooting Solutions.
Symptom Poor Performance Leaking Oil Possible Causes Restricted Inlet Possible Sources Clogged Filter Element Collapsed Inlet Hose Erroneous Pressure Loose Gauge Connection Gauge Movement Damaged Gauge Inaccurately Calibrated Air Leakage Improper Relief Valve Setting Blown Gaskets Loose Piping Joints Insufficient Rotor Speed Wrong Sheave Set Wrong Motor Speed Slipping Belts Excessive Rotor Clearances Abrasive Wear of Rotor Surfaces Rotor “Lag” Timed Failed Oil Seals Foreign Material in Seal Bor
Symptom Overheating Possible Causes Excessive Pressure Ratio Possible Sources Clogged Filter Element Collapsed Inlet Hose Clogged Dust Vent Filter Undersized Dust Vent Filter Clogged Diffusion Pads Wrong Sheave Set Wrong Motor Speed Slipping Belts Insufficient Rotor Speed 4. Pulse Arm Drive – Motor not rotating. A. Remove the motor from the gear drive and check for proper operation. If the motor does not rotate, repair or replace. B.
SAFETY RECOMMENDATIONS Because this unit may be under pressure, do not attempt to open any device doors or panels while fans or blowers are running. If your unit is equipped with a discharge auger or an airlock, be sure chain guards are installed before start-up and servicing is attempted only after electrical power is locked out. While servicing the filter, it is very important that there are no open flames, welding or grinding sparks.
ROUTINE MAINTENANCE A. Inspection Frequency will vary as widely as there are operating conditions. In general proceed as follows: 1. Daily – Check unit differential pressure. 2. Weekly – Verify that the pulse arm drive and PD Pump are operating properly. 3. Monthly – Lubricate fan, rotary valve and screw conveyor. Check seals on latter two for dust loss. 4. Quarterly – On Top Access Units, check for dust accumulation in clean air plenum. B. Repairs 1.

Safety Precautions It is important that all personnel observe safety precautions to minimize the chances of injury. Among many considerations, the following should be particularly noted: • • Blower casing and associated piping or accessories may become hot enough to cause major skin burns on contact. Internal and external rotating parts of the blower and driving equipment can produce serious physical injuries.
Installation ROOTS blowers & exhausters are treated after factory assembly to protect against normal atmospheric corrosion. The maximum period of internal protection is considered to be one year under average conditions, if shipping plugs & seals are not removed. Protection against chemical or salt water atmosphere is not provided. Avoid opening the unit until ready to start installation, as corrosion protection will be quickly lost due to evaporation.
installation can be obtained by setting the baseplate on a concrete slab that is rigid and free of vibration, and leveling the top of the base carefully in two directions so that it is free of twist. The slab must be provided with suitable anchor bolts. The use of grouting under and partly inside the leveled and shimmed base is recommended. It is possible for a base-mounted assembly to become twisted during shipment, thus disturbing the original alignment.

In addition, make sure it is free of scale, cuttings, weld beads, or foreign material of any kind.
Technical Supplement for URAI® Gas Blowers Technical Supplement for 32, 33, 36, 42, 45, 47, 53, 56, 59, 65, 68, 615 Universal RAI-G blowers ROOTS Universal RAI-G rotary positive gas blowers are a design extension of the basic Universal RAI blower model. URAI-G blower uses (4) mechanical seals in place of the standard inboard lip seals to minimize gas leakage into the atmosphere. The seal vent chambers are plugged.
Lubrication For Units with a Grease Lubricated Drive End and is drained downward. A simple but very effective lubrication system is employed on the drive shaft end bearings. Hydraulic pressure relief fittings are provided to vent any excess grease, preventing pressure build-up on the seals. A restriction plug and metering orifice prevent loss of lubricant from initial surges in lubricant pressure but permit venting excess lubricant under steadily rising pressures.
Operation Before operating a blower under power for the first time, recheck the unit and the installation thoroughly to reduce the likelihood of avoidable troubles. Use the following procedure check list as a guide, but consider any other special conditions in the installation. J J J J J J J J Be certain that no bolts, tools, rags, or debris have been left in the blower air chamber or piping.

Inspection & Maintenance: Universal RAI® series blowers A good program of consistent inspection and maintenance is the most reliable method of minimizing repairs to a blower. A simple record of services and dates will help keep this work on a regular schedule. Basic service needs are: any reason. Some oil seal leakage may occur since an oil film under the lip is required for proper operation. Periodically leaked oil should be wiped off from surfaces.
