Almost 70 percent of plant equipment failures stem from improper installation, lack of maintenance or incorrect start-up and shutdown procedures. When equipment fails, the biggest cost is time —production time and maintenance staff time. Add to that the price of repairing or replacing components more often than planned, and the total cost of ownership soars. To reduce unplanned maintenance and avoid unnecessary replacement costs, John Crane Equipment Service oversees critical systems checks and plant equipment maintenance, as well as engineered component repair, removal and reinstallation services. Assistance can be provided during unplanned shutdowns to get equipment back up and running quickly, or during planned maintenance to optimize your process and achieve your shutdown window.
Risks of Misalignment
Due to the excessive vibration it can cause, inaccurate shaft alignment is one of the most common culprits of seal damage, bearing failure and coupling failure. Even the most conservative surveys indicate that 50 percent of all machine breakdowns are directly due to poor alignment, and some show that up to 90 percent of machines are running beyond their recommended tolerances. John Crane understands the importance of proper alignment, and our engineers have a full set of diagnostic tools at their disposal to identify signs of misalignment or improper installation:
- Laser alignment
- Differential temperature measurement
- “As-fitted” applications data bank
All John Crane plant equipment maintenance services are available on a contract or as-needed basis. By scheduling timed, frequent health care checks, customers can uncover potential problems early on, providing opportunities for corrective or preventative measures that could help maximize uptime and limit the need for reactive maintenance. To identify possible risks, we evaluate the entire process — rather than just an isolated system — and then help optimize it to reduce maintenance costs and improve overall reliability.
