Pump predictive maintenance

Pumps are at the heart of most industrial processes. Because pumps are often overlooked as a potential source of improved productivity or a cause of excess costs if not operated properly. 

Predictive maintenance takes our maintenance service to the next level. By continually monitoring the condition of a pump, we are able to predict when it will require maintenance rather than rely on preset time intervals. The outcome is usually an extension in operating life between maintenance outages. Predictive maintenance is a process that is routine-designed for our specific system, built out of regular observation and record keeping to understand trends and uncover irregularities. End users can, therefore, influence this chronological data to take future actions to optimize their operational efficiency. Predictive maintenance is an effective way to reduce your operational costs. 

Predictive maintenance includes:

Vibration Analysis

Bearing temperature  

Laser Alignment

Field Balancing

Ultrasonic Leak Detection

Infrared Thermography

Motor Current Analysis

Mechanical Repair

Oil Samples

Some predictive maintenance techniques are explained as below:

Temperature trending

Temperature trending measures that part of an object’s energy that noticeable itself as temperature, which is useful for locating potential production problems. For example, it identifies cooler-than-normal blocked steam traps and overheated hardware elsewhere in the plant. Heat produced by friction will also raise an object’s temperature. The temperature of constantly rubbing mechanical components, such as bearings, gears and mechanical seals, will rise if effective measures to minimize friction aren’t taken. 

Vibration analysis

In industrial plant hardware attribute rotating elements. Examples include compressors, fans, turbines, gearboxes and pumps with their motors, bearings, rotors, fan wheels, impellers and seals. Depending on its speed and degree of imbalance, a rotating element can generate a vibration that shakes the machine, its foundation and, possibly, the building structure itself. Recording vibration signals provides view of the bearing’s time-domain vibratory signature. Thus, vibration analysis distinguishes the shivering that originates with a faulty bearing from that of an out-of-balance rotor.

Lubrication analysis

Oil or grease between mechanical components minimizes heat-producing friction and cools the parts. Such lubricants consist of a base stock equipped with a variety of additives that steady the lubricant’s physical and chemical properties to maintain its high performance. However, any lubricant will give in to the rigors of complete use and its protective properties will degrade over time. Oil analysis alerts a plant that such degradation is occurring. The technique involves subjecting a lubricant sample to laboratory testing that make known, among other things, how well it can neutralize acids and resist oxidation that breaks the lube into small, ineffective molecules.
