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 general arrangement drawing. Fan platforms are mounted onto bolt-on mounting gussets that attach to the sidewall. 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.
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.
PRODUCT HIGHLIGHT Snapband BEADED SNAPBAND FILTER BAG DESIGN FOR FLAT TUBESHEET HOLE The snapband was developed to improve sealing efficiency. This design eliminates multiple parts, minimizing labor expenses. Camcorp provides a uniform double beaded gasket in the cuff assembly. This assures a leakproof seal for flat plate tubesheet holes. When installing the bags, follow instructions provided. PROPER INSTALLATION OF THE CUFF 1. Form the snapband into the shape of a kidney.
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.
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 sweep arm drive motor (direction of rotation is not critical). B. Start the reverse air fan motor and check rotation. C.
SHUT-DOWN PROCEDURES 1. Dust control 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. 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. 8-1 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 reverse 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 reverse 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. Fan - If the fan is not operating properly please refer to the New York Blower manual located in this IOM manual. 2. Sweep 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. If the motor does rotate properly check for binding or roughness in the gear drive. Repair or replace one or both gear boxes as necessary. 3.
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 sweep arm drive and reverse air fan 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.
