Pretech brings a complete program of testing, analysis and correction design for maximum facility machinery performance - Our expertise in dynamic measurement, vibration analysis and diagnostics supported by extensive laboratory and electronic field testing enables us to identify which types of critical maintenance your facility equipment needs and when it should be performed.
With "World Class" maintenance, we can find practical solutions for structural design deficiencies or mechanical malfunctions before they develop into costly failures and shutdowns.
If failure has already occurred, Pretech's experience, skill and objectivity as outside consultants will bring your machinery system back to full, reliable productivity and profitability with its comprehensive scope of analytical design and engineering services.
Defining the Problem
Increasing and excessive mechanical vibration represents an important warning of impending machinery failure. The information embedded in the vibratory responses can be interpreted by Pretech with a great degree of accuracy in relation to severity, specific causes and contributors to the failure.
Pretech's test programs and detailed forensic procedures are all aimed at determining the root cause of abnormal behavior in a mechanical system so that a precise description of the problem can be stated as early as possible in the solution process.
Field Testing and Analysis
With the problem defined, a series of Field Tests and parametric analysis under real operating conditions may follow. These tests verify the problem definitions and constitute the data on which the solution is eventually based. Many different process and motion variables are normally included in order to make both the diagnosis and correction applicable to the entire range of operating conditions.
Mathematical Modeling
Often, the complexity and number of contributing parameters require computer modeling of part or total system in order to understand and correct the entire scope of the problem.
A mathematical model is then developed and calibrated against actual field data so that a computer simulated real system can be used to evaluate and employ potential corrective actions with predetermined success.
Designing the Solution
Frequently, the test data alone presents a clear diagnosis and immediate course of corrective action. However, identical failures in system elements often occur repeatedly over time. This normally indicates a generic design problem and in such cases, Pretech's mitigation designs based on results generated by the dynamic model can be rapidly evaluated and optimized for a solution that is right for the first time.
Predictive Maintenance (PdM)
Generic problems aside, recognizing that mechanical equipment performs well most of the time, Pretech's PdM program offers the optimum in cost-effective failure protection. This low cost trending service measures and reports mechanical conditions on monthly, quarterly or annualized bases. PdM offers tremendous budget flexibility while reducing your shutdown exposure.
Contact us here for more information on this resource. Pretech's PdM can insure your machinery's continued reliability.
Vibration Control Systems
Pretech is aggressively engaged in alternate and advanced vibration control through Active and Passive reduction methods when conventional technologies prove impractical or inadequate.
Our evaluation, problem solving and solution development experience have provided a database of thousands of case histories from which to draw, compare findings and prepare studies. Our objective is to offer clients an ongoing source of information and services for improving cost effectiveness and optimizing equipment performance.
