  • Page 24 6. Gathering Material: a. Use the open end of the bore to pick up the mate- rial. b. Use the tube or spread wands to pick up material. c. Several types of tubes or wands are available to use. The operator can select the one most appropriate for their application.
  • Page 25 9. System Grounding: Granular material flowing through pipes, hoses or lines can generate an electrical charge that will create electrical discharges, static and/or sparks. In high dust environments sparks or electrical discharges can set off an explosion. This static charge condition can be very annoying to an operator.

With the intended operation in dusty and dirty environments, the blower life is not compro- mised from contaminants entering the system.
  • Page 27 11. Airlock: The system is designed with an airlock to remove material from the air flow. It is located under the receiver tank and the collected material drops into an airlock compartment as it turns. As the rotor turns and a com- partment moves from its up position to its down position, the material in the rotor compart-...
  • Page 28 14. Operating Hints: a. Lock out tag out master panel before performing any service or mainte- nance work on machine or unplugging airlock. b. Maintain electrical conti- nuity through all compo- nents to prevent sparks, shock or electrical dis- charges. Do not use plastic components.

  • Page 29: Storage

    Follow this procedure: 1. Clean the entire machine thoroughly using the Central-Vac to remove all dirt, debris or residue. 2. Gather all hoses, inlets and wands and store them so they will not be damaged during the down time.

    MAINTENANCE By following a careful service and maintenance program for your machine, you will enjoy many years of trouble-free service. 5.2.1 BELT TENSION AND ALIGNMENT Rotational power from the electric motor is trans- mitted to the blower through the belt drive. To obtain efficient transmission of power and good belt life, the belts must be properly tensioned and the pulleys aligned.
  • Page 37 4. Use the appropriate weight to determine the belt deflection in a static condition (Table 1). 5. Adjusting Tension: a. Loosen the jam nuts on the motor base and position adjusting bolts. Loosen base Fig. 5-11 BELT DEFLECTION position bolts slightly.
  • Page 38 6. Pulley Alignment: a. Lay a straight-edge across the faces of the two pulleys. WARNING Machine is shown with guard removed for illustrative purposes only. Do not operate machine with guard removed. b. If the gap between the pulley and the straight-edge exceeds 1/16 inch (1.5 mm), the pulleys must be realigned.
  • Page 39 d. Use the position adjusting bolts on the motor base to align the input pulley. Tighten motor base anchor bolts and jam nuts when alignment has been completed. WARNING Machine is shown with guard removed for illustrative purposes only. Do not operate machine with guard removed.

  • Page 40: Blower Oil Changing And Breather Cleaning

    5.2.2 BLOWER OIL CHANGING AND BREATHER CLEANING The gears that drive and time the blower lobes run in an oil bath for lubrication. Maintaining the correct level in the reservoirs and changing every 100 hours will insure proper lubrication. When maintaining the blower, follow this procedure: 1.
  • Page 41 Do not contaminate the worksite with used oil. e. Install and tighten the drain plugs. Remove fill and level plugs. g. Add Walinga Blower oil or equivalent to each reservoir until the oil is just starting to come out of the level plug hole.

  • Page 42: Airlock

    5.2.3 AIRLOCK The airlock acts as a seal between the vacuum and atmosphere sides of the machine and is located at the bottom of the collector cyclone tank. As the airlock rotor turns, a pocket is filled with material when it points upward. As the pocket rotates, it is moved to the bottom where the material drops out of the pocket into the discharge pipe.
  • Page 43 4. Wiper Blade: WARNING A wiper blade is located at the top of the airlock to clean the tips as the airlock turns. Lock out tag out master panel before inspecting or maintaining airlock. To check the wiper blade, follow this proce- dure: a.

  • Page 44: Chain Tension And Alignment

    5.2.4 CHAIN TENSION AND ALIGNMENT Rotational power to drive the airlock is provided by an electric motor through a chain drive system. To obtain good chain life, the chain must be properly tensioned and the sprockets aligned. Chains that are too tight will stretch and wear quickly or over load the bearings.
  • Page 45 6. Sprocket Alignment: a. Lay a straight edge along the sides of the 2 sprockets. b. If there is a gap of more 1/16 inch (1.5 mm) between the sprockets and straight edge, the sprockets must be aligned. c. Use the position adjusting bolts on the motor base to move motor/ sprocket for alignment.

  • Page 46: Trouble Shooting

    TROUBLE SHOOTING The Walinga Central Vacuum System is a high capacity air pump that creates a vacuum for picking up granular material and supplies pressurized air for moving the material. It is a simple and reliable system that requires minimum maintenance.
  • Page 47 CAUSE SOLUTION PROBLEM Slow discharge of material Air leaks. Tighten all pressure connections. Be sure cam locks are in good condition. Dirty or plugged intake filter. Clean or replace intake filter. Defective blower. Check clearance between lobes and case. Excessive clearance will decrease air flow.
  • Page 48 PROBLEM CAUSE SOLUTION Tips hitting case. Readjust tips where applicable. Noisy airlock. Airlock stalls. Airlock jammed. Remove obstruction from airlock by opening inspection door or discharge line. Lock out tag out master panel. WARNING Do not work on airlock unless you lock out tag out master panel.
  • Page 49 CAUSE SOLUTION PROBLEM Motor overloading. Impellers rubbing. Consult your nearest dealer. Loss in drive speed. Belts slipping. Tighten belts as required. Localized belt wear. Check cross-section dimension. a. If narrow, pulley spinning. b. If swollen, belt failing internally. Unequal stretch on belts. Defective belts.
