Lubricating oil pump installation instructions
Lubricating oil pump installation instructions:
1, pump installation is good or bad for the smooth operation and service life of the pump has a very important impact, so installation calibration must be careful to not act in haste.
2, height, length and diameter of the pump suction pipe installation shall meet the calculated value, as brief as possible, to reduce unnecessary losses (elbow); ensure that the pump at work, no more than allow the NPSH.
3, the suction and discharge piping should bracket. The pump is not allowed to bear the load of the pipeline.
Pump installation location should be spacious enough to facilitate maintenance work.
Installation sequence:
1 unit on the buried anchor bolts on the basis of the correction between the base and the foundation, with a pair of wedge pad.
2, release the coupling on the shaft and the base of a level, by adjusting the wedge pad, correction unit level, properly tighten the bolt to prevent the move.
Correction Lubricating oil pump shaft and motor shaft concentricity of the outer circle of the coupling road, allowable deviation of 0.1 mm; the two coupling plane gap should ensure that the 2 to 4 mm (small pump take a small value) gap should be uniform, tolerance of 0.3 mm.
4, connected piping and determine the direction of rotation of the motor, connect the coupling, and then check again axis concentric aromatic.
5, unit 2 to 3 hours after the actual test run for a final check, if no adverse phenomenon that install qualified. Check the bearing temperature and vibration in the process of trial operation as follows:
6, during installation, to prevent debris falling into the machine, all of the perforations of the unit should be covered.
7, in order to prevent the debris in the pipeline into the pump, the filter shall be installed in the Lubricating oil pump glue on the new installation of the pipeline, its effective cross-section of the suction pipe section should be greater than 2 to 3 times.
