Alignment of compressors

There are many types of compressors used in the industry, main of them are: piston, rotary, centrifugal, axial and jet compressors. All the compressors , as a rule, serve to feed air or gas under strong pressure, which can’t be made by a blower.

Compressor shaft rotation speed varies from 60 to more than 20 thousand rpm depending on a type, performance, volume and consumed power. During the compressor operation a lot of forces are acting on it that can lead to the compressor defects and its emergency shutdown. One of such forces appears as a result of the compressor shaft misalignment. The misalignment correction is a hard but top-priority objective.

All the alignment specialists must consider all the factors that influence the misalignment. Among such factors are shaft beat, soft foot, bearing defects, clearances in couplings and dynamic movements.

The alignment specialists should have a precise special alignment system such as the BALTECH SA-4300 alignment system which allows performing the alignment with the accuracy up to 0.01 mm in the automatic mode and create the alignment reports. The BALTECH SA-4300 alignment system is simple, easy- to –use and reliable.

BALTECH SA-4300 makes it possible to perform alignment of compressors with taking into account and correcting such defects as soft foot, shaft beat, piping connection tension, clearances. BALTECH SA-4300 automatically calculates a rod deflection, thermal expansion and many other defects. The device performs on-line alignment by showing automatically in what direction the machine should be moved. You can select between two alignment methods- rim and face or reverse indicator method. Based on the alignment results the system automatically creates the alignment report. The report can be transferred to the BALTECH-Expert software for analysis and trending. The BALTECH-Expert software is compatible not only with the alignment systems but also with the vibration diagnostics equipment , balancing devices and infrared cameras BALTECH TR-01500.

The alignment specialists should have not only precise measuring tools (for example, the alignment shims BALTECH-23458N Series), but also vast experience in order to ensure the reliable machine operation. Any specialist can receive training on how to perform the compressor alignment and gain practical experience in working with the alignment systems BALTECH SA-4000, -4100, -4200, -4300 on the BALTECH technical seminars «Reliability technologies» .

The compressor equipment reliability directly depends on the properly performed alignment work. The BALTECH SA-4300 system allows to carry out the accurate and reliable alignment of the compressors.
