Pumps are essential components in power transmission and liquid processing systems. When a pump fails, it can lead to cascading equipment failures, resulting in costly downtime. The higher the cost of a pump, the more complex its operation, making continuous monitoring of its condition increasingly important. Especially when a failure has not yet caused a shutdown, proactive monitoring becomes critical. Pumps are highly sensitive to equipment conditions, acting as key indicators of overall system health. Issues like damaged slip ring seals or dry sliding bearings can cause serious damage to impellers and housing.
To enhance equipment usability, it’s crucial to understand how the pump's behavior reflects the condition of the entire system. This understanding is the foundation for developing an intelligent pump diagnostic and monitoring system. The goal is to translate this relationship into a minimal set of sensor configurations. Based on fault data from service organizations and users, 2–3 sensors are typically sufficient to monitor pump performance and identify potential issues. These sensors help detect:
- Whether the pump is running without lubrication
- The temperature of the bearings
- The vibration amplitude of the pump
For end-users, being able to clearly interpret the pump’s condition is vital. Simply measuring individual values and analyzing them separately is not efficient. It requires users to perform their own logical integration and set threshold-based alarms, which demands a basic understanding of pump operations. If the only purpose is to prevent failure, this approach limits the depth of insight into the pump’s condition. When identifying abnormal operation, users often want to know exactly which component is faulty. Therefore, evaluations should go beyond simple threshold checks.
By intelligently analyzing and integrating data from each sensor, we can gain a much broader understanding of the pump’s status. This allows us to detect issues early and even determine their root causes. The Pump Expert system exemplifies this approach. It uses a few strategically placed sensors to monitor the pump and connected equipment. The system’s signals are compared with expert knowledge stored in its database. Fault list analysis is also employed, where measurements are evaluated against predefined thresholds and logically connected. The system then generates and displays error reports based on these connections.
This method also enhances decision-making by providing context, thresholds, and logical relationships. For example, if the pump hasn’t reached a set threshold, the logic unit may still indicate a potential risk. With modern electronics and microprocessors, all this data can be processed and displayed in real time.
This approach enables users to quickly identify damaged parts and sometimes even diagnose the cause of the issue. Statements like “sliding bearing wear,†“stuck rolls,†or “excessive gas in the liquid†become possible through the system’s analysis.
The automatic and comprehensive evaluation of data leads to specific recommendations for operators. Communication options include local displays, infrared interfaces, bus connections, and remote data transmission—ensuring that users have access to the information they need. The Pump Expert system is designed with user-friendly interfaces and advanced human-machine interaction technology, making it easy to use and understand.
Diagnosis and communication settings can be customized for different applications, and installation is straightforward. The system is compatible with various types of pumps and can send data to higher-level management systems. The explosion-proof version of Pump Expert is suitable for hazardous environments.
Combining data analysis with actionable insights represents a major advancement in improving pump performance and overall process efficiency. It reduces maintenance efforts and marks a significant step toward predictive maintenance.
