CENTRIFIUGAL PUMPS Design & application Second Edition This page intentiTonally left blank CENTRIFUGAL Part4: Extending Pump Life 495 19 Alignment 497 by Malcolm G. Murray, Jr. The following example, will demonstrate the procedure necessary to design and layout a new impeller. Maintenance procedures in this manual do not cover aseptic or high pres-sure pump applications. Large bearings and shaft provide positive alignment and minimize vibration. The casing is clamped to the motor adapter bracket (close coupled) or bearing housing (base mount) for easy disassembly 9.2 Active Q-switch alignment procedure. 9.3 Intra-cavity second harmonic generation with Q-switched laser. Optical pumping is a process in which light is radiated into a specimen under investigation and the effect of the light on the specimen is examined. WIK Centrifugal Pumps. Radially Split, Multistage Barrel Pump, Cartridge. PCN=BO2662 5/09 (E) Original Instructions. 62 Figure 6- 9 : Pressure Dam Bearing Alignment.. Regardless of how many sets of mounting pads your baseplate may have, the leveling procedure is essentially the same. NOTE: Proper alignment is essential for long pump life. If equipment is to be installed in a potentially explosive atmosphere and these procedures are not Alignment procedures must be followed to prevent unintended contact of rotating parts. Follow coupling manufacturer's coupling installation and Final Alignment (Hot Alignment). • After First Run - To obtain correct alignment when both pump and driver are at operating temperature. Thereafter, alignment should be checked periodically in accordance with plant operating procedures. and alignment instructions 8.1 - Monoblock pump/motor and pump/motor assembly mounted on a baseplate 8.2 - Alignment procedure for monoblock After the causes for the emergency have been addressed and resolved, it will be necessary to follow the starting procedures (see chapter 10) for the Pump Alignment: Just The FactsProper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability. (Vertical pumps, solid couplings and hollow-shaft motors present unique concerns and require special procedures not discussed here.) Pump alignment procedures, Coupling alignment methods, How to do pump alignment, Motor and pump alignment, Pump shaft alignment, Vertical pump alignment, How to align a pump, How to check pump alignment, Wages for civil engineers, Salary of an engineer, Pay rate for engineers Step 2: Pump Beam (Laser) Alignment Before starting the laser alignment procedure, please place your sample, ideally [Ru(bpy)3]2+ dissolved in water in a 1 cm cuvette at an appropriate concentration for the pump excitation wavelength you will use. 5.5.2 Pump alignment tolerances. 5.5.3 Taking into account peak height changes. 5.5.4 Checking the coupling alignment. 5.5.5 Aligning the motor. With cold alignment take into account peak height changes under the influence of the operating temperature according to the following figures. Installation. Pump alignment. Pumps direct coupled to motors / engines on bedplates are accurately aligned at our Works before despatch. Before start up procedure, make sure you have installed your pump correctly, checked coupling alignment, filled the pump with liquid and checked Installation. Pump alignment. Pumps direct coupled to motors / engines on bedplates are accurately aligned at our Works before despatch. Before start up procedure, make sure you have installed your pump correctly, checked coupling alignment, filled the pump with liquid and checked The objective of any aligning procedure is to align shafts (not align coupling hubs) by using methods that cancel out any surface irregularities, shaft-end float Pump-to-driver shaft alignment must be per pump's alignment requirement. • Be sure all coupling set-screws and bolts are tight and coupling gap Horizontal pumps - LNGT Alignment is achieved by adding or removing shims under the motor feet and also moving the motor horizontally as required. In some cases where the alignment cannot be achieved it will be necessary to move the pump before recommencing the above procedure.
