Pump is the liquid in the equipment and production process Once the pump fails, it can cause the breakdown of other equipment, resulting in the shutdown. The higher the manufacturing cost of a pump, the more complex the mode of operation, the greater the importance of continuously measuring and monitoring the working condition of the pump. Especially in the pump has some failures have not yet led to the occurrence of downtime, take the relevant monitoring measures is very necessary. Because the pump is very responsive to the condition of the equipment, the pump is also an indicator of the condition of the equipment, such as damage to the slip ring seals and non-lubricated running of the sliding bearings, which causes damage to the work wheels and the housing. In order to improve the usability of the equipment, it is necessary to understand the relationship between the equipment state and the reaction of the pump body. This is also the basic premise and starting point for developing a new intelligent circulating pump state diagnosis and measurement system. The purpose is to put this logic The relationship translates to a minimum configuration of sensing elements. From the analysis of service organizations and users on the fault statistics, it can be seen that the use of 2 to 3 sensing elements is enough to measure the operating status of the pump and diagnose the pump to a certain extent. The purpose of the sensing element is to: identify the pump in a non-lubricated operating condition; determine the temperature of the bearing; determine the vibration amplitude of the pump. For users of this type of equipment, it is extremely important to be able to express the working state of the pump body in a concise manner. Therefore, it is not feasible to measure a value with a measuring device, interpret each measurement separately, and then integrate the measurement values ​​(Figure 1). In this case, the user must make his own logical reasoning based on the data synthesis, to reach a conclusion. Set the corresponding threshold pre-alarm on the basis of actual work, which is also a very important step. It is just this practice that requires the user to have a basic knowledge of the pump in order to set the appropriate threshold for the pump. If this measure is only to prevent the failure of the role, then it is very limited expression of the working state of the pump body. In determining the pump body is in an abnormal working condition, people often ask what is the pump body which element is damaged. Therefore, the evaluation of the working state of the pump can not only stay in the simple determination of individual limits. By intelligently and intensively measuring and evaluating the data provided by each sensor, it is possible to greatly exceed the evaluation range of a single indicator, thereby fully understanding the working state of the pump body and the equipment. For this purpose, you can use the circulating pump diagnostic system - Pump Expert. This system can monitor the working status of the pump body and equipment with just a few sensor elements installed on the pump body. The various signals of the system are interconnected and compared with the stored intelligence experts. In addition, you can also use intelligent diagnostic methods such as fault list analysis (Figure 2). First, pick out convincing measurements from the wrong tree structure. For each set of measurements there is a corresponding measurement threshold, which is then logically connected to each other. According to the connection error report generated and displayed through the monitor. This method also provides additional information when making intelligent choices, thresholds, and connections: When the pump has not reached the set threshold, the logic unit signals that the pump will be in danger status. With the help of electronic devices and microprocessors, these data and signals can be connected. Take this method can be promptly identified the location of the pump body damaged parts, and sometimes even can determine the cause of the malfunction. Users of the pump body can make statements such as: Sliding bearing damage, wear, stuck work rolls, excessive viscous fluid medium, incorrect adjustment, equipment not filled with liquid, too much gas in the liquid , Cut off, the cooling of the bearing seat by the motor cooling air interference. The automatic and comprehensive evaluation of the data in order to make specific recommendations to the operator is the hallmark of this new approach. Local communication through the display, local infrared interface, bus connection, remote data transmission, which are created for the use of information. All available communication means can now be used. Users can not only prevent a single pump failure, but also can grasp the running status of the equipment. The Pump Expert system is renowned for its easy-to-use and easy-to-understand display and operator interface with the latest human-machine interaction technology. Diagnosis and communication content can be flexibly set according to various occasions. System installation is also very simple. This system also applies to a variety of different types of pump body. The obtained data information can also be transmitted to a higher level management system for use by a higher level management system. The explosion-proof Pump Expert system can be used in areas with an explosion hazard. A combination of data and information analysis is a big step forward in improving the performance of the pump body and the entire process, reducing the intensity of service and maintenance efforts, and is a first step toward preventive maintenance.
