The quality of the alignment effect directly influences the service life of the equipment; the length of the alignment time directly influences the construction period and the economic benefit of the site construction.
The traditional coupling centering alignment method comprises the following steps:
1) determining a magnetic meter stand with a proper specification and model according to the coupling spacing required by the drawing;
2) the alignment is usually carried out by a double-surface method (namely, a circumferential section method) in the construction. The magnetic meter frame is fixed on the two half couplers and is fixed by utilizing the magnetic force of the magnetic meter frame;
3) after the frame meter is fixed, rotating the half couplers, keeping the two half couplers to rotate around the same axis, and keeping synchronization so as to avoid influencing a measurement result, and observing the reading change of the dial gauges at two ends from 0 degree, 90 degrees, 180 degrees and 270 degrees;
4) and making corresponding records, and if the deviation value is overlarge, adding a gasket for adjustment until the measurement result is within the specification requirement range.
The method has the following disadvantages:
1) the meter frame needs to be purchased in the market, the specification and the model are different, a large amount of purchase is needed, and some special models are not easy to purchase;
2) the watch frame is easy to damage and cannot be repaired, and is easy to vibrate, loosen and fall off in use, the measurement result is inaccurate, repeated measurement is needed, and the measurement result is verified;
3) the meter frame has a limited measuring range and is only suitable for mechanical equipment with a small distance between couplings;
4) the purchase of the meter frame requires capital expenditure, and repeated measurement causes an increase in construction cost and an extension of a construction period, and is not economical.
