  • Page 5: Glossary

    The Model W-105 is equipped with a 1/2 HP motor, and the Model W-105Z with a 1 HP motor. The standard motor is totally enclosed. Acrison offers both AC and DC variable speed drives for use with the Models W-105 and W-105Z Volumetric Feeders. Depending upon the type and model controller selected, either a 10:1, 20:1, 30:1 or 50:1 speed range is available.
  • Page 6 Conditioning Chamber. Model W-105 and W-105Z Conditioning Chambers are designed without any type of convergence that could prove detrimental to product flow and/or feed. DC Motor — DC Motors are frequently used to power the Model W-105 Series of Feeders for variable speed control.
  • Page 7 DC motor speed regulation, linearity and repeatability. Acrison SCR controllers that provide a 50:1 drive turndown ratio, or those used in conjunction with Acrison weigh feeders, utilize a Tachometer for speed feedback data. The Tachometer may be directly connected to the output shaft of the DC motor, through a specially designed gear-reducer, or may be installed between the motor and gear-reducer.

  • Page 8: Installation And Operation

    Wetting Cone (Optional) — Operating in conjunction with an Acrison Volumetric Feeder, Acrison’s optional Wetting Cone has been specifically designed for “wetting” activated carbon, potassium permanganate and certain other dry chemicals. 3.0 INSTALLATION AND OPERATION Ù WARNING: OBSERVE ALL WARNING AND/OR CAUTION LABELS. Do not ap- proach any rotating object while the feeder is operating or connected to a power source.

  • Page 9: Feed Output Adjustments

    All wiring to the equipment must be made by the user or pur- chaser. This includes all interconnections between the equipment and any Acrison supplied control panel(s) as well as any safety switch(es) and/or safety interlock(s) either required by law and/or the electrical standards of the user.

  • Page 10: Operational Adjustments

    3.3.1 The speed (ratio) between the smaller metering auger and the Intromitter (or conditioning auger) is preselected based on the characteristics of the specific material to be metered, factory preset for optimum performance. If any feed-related problems are encountered, Acrison should be consulted for assistance.

  • Page 11: Maintenance-Disassembly/Reassembly

    NOTE: The preceding Capacity Chart indicates the typical output range for each size metering auger available with the Model W-105 and W-105Z Feeders. However, since the physical properties of the actual product being metered may have an effect upon the exact output, the stated capacities could vary.

    Conditioning Chamber (6). If a Model W-105 or W-105Z Feeder is an integral component of an Acrison Model 500, 512 or 515 polymer processing Module, the Discharge Cylinder (12) will be furnished with either an atomizing tee adapter assembly (Model 500) or a slam gate arrangement (Models 512 and 515).

  • Page 13: Conditioning Chamber

    4.4 Conditioning Chamber (6) Please refer to Figures 1 and 2. 4.4.1 Remove the Discharge Cylinder (12), the Intromitter or Conditioning Auger (8) and the Metering Auger (10). Install a temporary chock beneath the front side (feeder side) of the Gearbox (3), between the gearbox and the Feeder Mounting Base (4), to provide support once the Conditioning Chamber (6) is removed.
  • Page 14 4.5.4 To remove Gears (23) and/or Gear (24), loosen the two set screws on each adjacent Countershaft Bearing (31) and the two set screws on each of the gears. Slip Countershaft (28) out through the back of the Gearbox (3) far enough to remove the gear or gears. 4.5.5 To remove Gear (25), follow the procedure outlined in the preceding paragraph 4.5.3 for removing Gear (22).

  • Page 15: Replacing Seal Packing

    4.5.8 If the Gearbox (3) must be removed, remove the bolts fastening the Seal Housing (5) to the Conditioning Chamber (6) and the bolt fastening the Gearbox (3) to the Feeder Mounting Base (4). Remove the Gearbox (3), Seal Housing (5) and Gear-reducer (2), with or without Motor (1), as an assembly.

  • Page 16: Universal Gearbox

    NOTE 1: The ends of each ring of packing are cut at a 45 degree angle. Make certain that when installed, the packing ends meet as depicted in Detail “A” of Figure 4. Failure to do so could result in premature seal failure. NOTE 2: To remove either the Metering Auger Drive Shaft (11) or the Intromitter (or Conditioning Auger) Drive Shaft (9) from within Type PB Gearboxes (3), please refer to the Seal Housing and Gearbox Assembly, paragraphs 4.5.6 and 4.5.7 respectively.

  • Page 17: Drive Motor And Gear-Reducer

    Drive Shaft (11). Carefully examine the Metering Auger Drive Shaft (11) for wear and/or scoring; replace if worn or scored. NOTE: In order to best examine the Metering Auger Drive Shaft (11), the shaft may need to be moved forward. To accomplish this, please follow the procedure outlined in paragraph 4.7.1.

  • Page 18: Tachometer Assemblies (Dc Drives)

    Optical Tachometers generally apply to Acrison equipment produced prior to 2001. 4.9.1 When an Acrison volumetric feeder is equipped with a variable speed DC drive including an Optical Tachometer (45), a specially designed Gear-reducer (2), equipped with a high speed extension shaft, is utilized to drive the tachometer.
  • Page 19 Does not apply to the Model MPT 700 Series of Magnetic Tachometers. 4.9.4 When an Acrison feeder is equipped with a variable speed DC drive which includes a Magnetic Tachometer (99), the tachometer assembly installs between the Gear-reducer (2) and its drive Motor (1).

  • Page 20: Feeders With Quick-Clamp Construction

    NOTE 1: For proper operation, the center line printed on the sensor housing must be perpendicular to the gear teeth as shown in Figure 7. Also, please note that the center of the gear must be in-line with the center of the magnetic sensor, which is located in the aluminum ring, and that the clearance between the teeth of the gear and the sensor should be 0.008 to 0.012 inches.

  • Page 21: Feeders With A Hopper Isolation Pad Assembly

    Also, to transmit vibration uniformly throughout a hopper equipped with a Vibrator, and to confine the vast majority of vibration to the hopper, certain model Acrison feeders may be equipped with an Acrison innovated “Isolation Pad” (patented), mounted between the bottom of the feeder’s hopper and the top...
  • Page 22 (feed rate output). However during the initial start-up/checkout of a Model W-105 Series Feeder furnished with a hopper equipped with a Vibrator, the effectiveness of the Vibrator to ensure proper product flow requires verification by the Acrison Field Service Representative. Typically, a Vibrator is factory set for a nominal amount of vibration (mid-range setting).

  • Page 23: Maintenance-General

    Disconnect the feeder from all power sources prior to performing any maintenance whatsoever. Acrison’s Models W-105 and W-105Z Volumetric Feeders have been designed to eliminate as much maintenance as possible; however, the following normal preventative procedures should be observed: 71 Bearings All bearings furnished with grease fittings are factory lubricated but should be periodically inspected and greased to maintain a slight leakage at the seals.

  • Page 24: Ac Variable Speed Drive

    Brush life is dependent upon the duty and severity of operation for a given application. The DC motor is furnished with permanently lubricated bearings. Refer to the separate instruction manual for information relating to the specific SCR/DC controller. 7.4 AC Variable Speed Drive (1 and 2) Lubrication should be in accordance with the manufacturer’s instructions as shown on the gear reduction portion of the drive or in the instructions enclosed with this Manual (generally, a high grade SAE 140 gear oil is recommended).

    Serial Number can be found on the nametag affixed to the Gearbox (3) and also, stamped onto the actual gearbox casting. NOTE 3: Acrison maintains a complete stock of all standard items used in the manufacture of this or any feeder and therefore, any standard component can usually be shipped anywhere immediately.
