Reliability Services – Condition Monitoring

Alignment

Proper alignment of rotating machinery is critical to machine reliability. Misalignment creates excessive vibration and high loads on bearings, couplings, rotating and non-rotating parts. Proper procedures and tolerances should be used when conducting alignment on all types of machinery including compressors, pumps, motors, turbines, generators, fans, and blowers.

CIS Industrial Services was appointed in late 2018 to be the preferred supplier to one of the worlds renowned Coal producing mines within the Witbank/Middelburg region, assisting this mine with all there alignments.

Shims

CIS Industrial Services offers high quality locally Manufactured pre-cut slotted Stainless-Steel shims for machinery alignment. All Shims are clearly marked for identification of size. Both English and metric version shims are available. Our pre-cut stainless-steel slotted shims are used for machinery alignment during machine installation and alignment servicing.

CIS Industrial Services offers complete shim kits, installer shim kits, service shim kits and replacement shim packs. Our shims are offered in Industry Standard sizes ranging from “AA” (1.50”x1.50”) through “H” 8”x8”. Please call for pricing on non-standard size shims or custom shim inquiries.

Balancing

Unbalance is a very common source of high vibration that is identified by excessive levels of vibration amplitudes at a frequency that is synchronous with machine speed. Possible sources for this malfunction may be uneven product deposits around a fan or pump impeller, damaged or missing blades or vanes, improper shaft component assembly, or any other uneven mass distribution around the rotor axis. A machine that is operated within design conditions and is clean should not experience severe unbalance vibration levels. The proper balance tool or analyser will assist in correcting these problems.

Condition Monitoring

Condition monitoring (CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance. The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences.

Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure. Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) evaluation are used for static plant equipment such as steam boilers, piping and heat exchangers.

CIS Industrial Services personnel has more that ten years of in the field experience within rotating equipment and attending on a daily basis to clients needs to ensure plant reliability and production targets are met with ease. 

Thermography

Also Known as Thermography, or Thermal Imaging Cameras. The use of Thermography, or Thermal Imaging, has increased dramatically with commercial and industrial applications over the past 20 years. Maintenance technicians use thermography to locate overheating power lines or data cables, which are a sign of impending failure. Building construction technicians use thermal images to indicate heat leaks in faulty thermal insulation and can use the results to improve the efficiency of heating and air-conditioning units.

Thermal imaging has also been a great tool to help homeowners save money, especially now that energy rates are on the rise. Heat loss and/or cold air influx can be detected and corrective actions can be taken to help improve the energy efficiency of residential and commercial structures. Thermal Cameras can be used to inspect electrical panels and receptacles on commercial and residential buildings to detect issues before there is a costly outage. Thermal imaging can detect hot spots in the electrical system not visible to the naked eye, which may be a precursor to a larger issue.
