  • Page 28: Concrete Foundation Preparation

    API Recommended Practices 686. ATTENTION The design of foundations is not responsibility of Ruhrpumpen. It is therefore recommended that the customer consult a competent specialist skilled in the field of foundations, to insure proper design/installation of the foundation.
  • Page 29 Solid Waste Pump Figure 4.1 Imaginary lines Build foundation approximately 3 inches (76 mm) larger overall than the pump baseplate for machines up to 500 horsepower (372 kW), and 6 inches (152 mm) larger for machines greater than 500 horsepower (372 kW) to provide ample anchorage for the foundation bolts.

  • Page 30: Leveling Baseplate

    Solid Waste Pump Use a template to accurately locate foundation bolts according to the General Arrangement. Choose foundation bolts of size specified in drawing (ASTM A36, M 1020 and ASTM A575 are recommended), they should be long enough to allow a minimum of two threads above the nuts.
  • Page 31 Solid Waste Pump ATTENTION There should be a minimum annular clearance of 1/8 inch (3 mm) between anchor bolt holes and the anchor bolts to allow for field alignments. DANGER Exercise proper caution when working under or around suspended objects. Using a precision level across baseplate pads, adjust jacking bolts as necessary to ensure that baseplate is level in all directions (See Figure 4.2), within 0.002 in/ft (0.2 mm/m).

  • Page 32: Grouting

    Solid Waste Pump NOTE Each jacking bolt should have a mounting pad, to distribute the stresses evenly. NOTE The baseplate should be mounted without distortion. Under no circumstances should the driver be higher than the pump. When baseplate is level, 'snug' the foundation bolt nuts, but do not tighten completely. 4.3 GROUTING* NOTE The information included in this section is intended as a general guideline.

  • Page 33: Grouting Procedure

    Solid Waste Pump 4.3.3 Grouting Procedure Verify that anchored bolt sleeves are clean and dry. Fill them with a nonbonding moldable material to prevent them from being grouted. The anchor bolt threads should be protected with tape before grouting. Provide a form around the baseplate to contain the grout. The form should be chamfered at all corners.
  • Page 34 Solid Waste Pump Tap baseplate to eliminate air pockets. ATTENTION It is imperative to get rid of all trapped air before the grout hardens. ATTENTION Check frequently for grout leaks. ATTENTION Leaks will not self-seal and may cause voids. Remove jackscrews and grout-forms once the grout has completely hardened (takes around 3 days).

  • Page 35: Anchor Tightening Torque Selection

    Solid Waste Pump 4.4 ANCHOR TIGHTENING TORQUE SELECTION To appropriately select an anchor tightening torque, follow this procedure: ATTENTION Prior to selecting a tightening torque, the nut and anchor material and their respective yield strengths must be known. 1.

  • Page 40: Piping The System

    Solid Waste Pump WARNING Do not start the piping and alignment procedures until grouting, preliminary alignment (as seen in the previous sections of this manual) and on site welding have been performed. ATTENTION In a new installation, great care should be taken to prevent dirt, scale, welding beads, and other items from entering the pump.
  • Page 41 Solid Waste Pump ATTENTION The design of piping and related systems is not the responsibility of Ruhrpumpen. It is, therefore recommended that the customer consult a competent specialist skilled in the field of piping to insure proper design/installation of all the piping.
  • Page 42 Solid Waste Pump Figure 5.1 Correct mounting of a cone type strainer. Disconnect the piping from the pump if you heat one side of the pipe to align the pipe to the pump. Pump and pipe flanges must be parallel; they should mate together without effort, and with the bolt holes properly in line.
  • Page 43 Solid Waste Pump ATTENTION In horizontal suction lines, reducers should be eccentric (with the flat side of the reducer on top). ATTENTION No obstruction within at least five pipe diameters of the suction flange should be fitted. ATTENTION Do not install unsupported piping on the pump. ATTENTION Make sure electrical connections do not impose any stress on the pump unit.

  • Page 44: Alignment

    Solid Waste Pump 5.2 ALIGNMENT IMPORTANT It is recommended to generally establish a maximum misalignment of 0.005” [0.127mm]. It is important to note that as the misalignment tolerance increases, the risk to the pumping equipment increases. Possible problems resulting from poor alignment could negatively affect the performance and durability of the equipment.
  • Page 45 Solid Waste Pump 3. Thermal Growth If there are thermal growth considerations on the piece of equipment, it is a good idea to get these numbers so that they can be added to or subtracted from the graphical solution before the equipment move is made, this is known as “Hot alignment”.
  • Page 46 Solid Waste Pump Figure 5.2 Example for reverse indicator graphical analysis. The next step is to determine indicator sag. Set up your bracket arrangement on a pipe. Set the indicator at '0' on top. Roll set up until indicator is at the bottom of pipe. It will read negative. In this example, it is found to be -0.005 inch (-0.127 mm).
  • Page 47 Solid Waste Pump Figure 5.3 Indicator sag. With the indicator bracket attached to the motor hub reading off the pump hub, rotate unit in 90° increments and take readings. Bottom reading is then corrected for indicator sag. Indicator sag in the example was determined to be -0.005 inch (-0.127 mm).
  • Page 48 Solid Waste Pump Figure 5.4 Motor shaft extension relative to the pump shaft center line. Now with the indicator bracket attached to the pump hub reading off the motor hub, rotate unit again in 90° increments. NOTE If you can set up both indicators at once, both sets of readings can be taken at one time. Bottom reading is then corrected for indicator sag.
  • Page 49 Solid Waste Pump Figure 5.5 T.I.R. second reading We have now located the motor shaft theoretical extension in two places: A. In the plane of the pump hub. B. In the plane of the motor hub. Drawing a straight line through these two points crossing the plane of the two motor feet. The shim adjustment can now be read directly off the graph.
  • Page 50 Solid Waste Pump C. REVERSE INDICATOR ALIGNMENT MORE THAN TWO UNITS GRAPHICAL ANALYSIS This method lends itself very well in solving alignment problems of three or more pieces of equipment in a line. To solve this problem, follow the steps already outlined for each coupling in the train. Plot the shaft to shaft relationship of each set of shafts.
  • Page 51 Solid Waste Pump Figure 5.8 Across the disc pack alignment graphical analysis example. The next step is to determine indicator sag. Set up your bracket arrangement on a pipe. Set the indicator at '0' on top. Roll set up until indicator is at the bottom of pipe. It will read negative. In this example, it was found to be -0.004 inch (-0.102 mm).
  • Page 52 Solid Waste Pump Bottom reading is then corrected for indicator sag. The indicator sag in the example was determined to be -0.004 inch (-0.102 mm). The -0.004 inch (-0.102 mm) was subtracted from -0.025 inch (- 0.635 mm) indicator reading to give an actual of -0.020 inch (-0.508 mm) reading. As this is a TIR (Total Indicator Reading) it is two times the actual center member center line location relative to the pump shaft extension or -0.020 inch (-0.508 mm) / 2 inches (50.8 mm) = -0.010 inch (0.254 mm).
  • Page 53 Solid Waste Pump The minus reading on the bottom indicates that the center member tips up as it extends away from the motor. Using a scale of one small division on the graph equals 0.001 inch (0.025 mm), plot the 0.006 inch (0.192 mm) as shown on the example.

  • Page 54: Lubrication
