Questionnaire and solutions of dredge pump during operation
Dredge pump, is also known as sand pump, slurry pump, submersible dredge pump, submersible sand pump, submersible heavy duty pump, is a new pump type designed and developed which are highly used for dredging, reclamation, seabed, sand dredging and piping. The pump is composed of two parts: motor and pump along with the mechanical seal assembly. The motor and the pump are combined with the same shaft (rotor). The entire pump has a short length and a compact structure. Equipped with a variety of protection devices, dredge pump operates safely and reliably.
The dredge pump is the delivery power of the liquid in the equipment and production process.
In the event of a dredge pump failure, it can cause other equipment to malfunction, resulting in a shutdown. The higher the manufacturing cost of the dredge pump, the more complex the working method, and the greater the importance of continuously measuring and monitoring the working state of the dredge pump. Especially when the dredge pump has some faults that have not caused the downtime, it is necessary to take relevant monitoring measures. Because the dredge pump is very sensitive to the state of the equipment, the dredge pump is also an indicator of the condition of the equipment, such as damage to the slip ring seal and unlubricated operation of the plain bearing, which causes damage to the work wheel and casing.
In order to improve the usability of the equipment, it is necessary to understand the relationship between the state of the equipment and the reaction of the dredge pump body. This is also the basic premise and starting point for the development of a new intelligent circulation dredge pump state diagnosis and measurement system. The purpose is to use this logic. The relationship translates into the lowest configuration of the sensing element. From the analysis of the fault statistics of the service organization and the user, it can be seen that the use of 2 to 3 sensing elements is sufficient to determine the operating state of the dredge pump and to diagnose the dredge pump body to some extent. The purpose of the sensing element is:
Identifying that the dredge pump is in a non-lubricated operating state;
Measuring the temperature of the bearing;
The vibration amplitude of the dredge pump was measured.
It is extremely important for a user using such a device to be able to express the working state of the dredge pump body in a concise manner. Therefore, it is not feasible to use a measuring device to measure a value, to separately interpret each measured value, and then to combine the measured values.
In this case, the user must make logical reasoning and draw conclusions based on the synthesis of the data. It is also an important step to set the corresponding threshold pre-alarm based on the actual work. It is only this practice that requires the user to have a basic knowledge of the dredge pump in order to set an appropriate threshold for the dredge pump. If this measure is only to prevent the malfunction, then its expression of the working state of the dredge pump is very limited. When it is determined that the dredge pump body is in an abnormal working state, people often ask whether the component on the dredge pump body is damaged. Therefore, the evaluation of the working state of the dredge pump body can not only stay in the simple measurement of the individual limit values. If the data provided by each sensor is intelligently and intensively measured and evaluated, the evaluation range of individual indicators can be greatly exceeded, and the working state of the dredge pump body and equipment can be fully grasped. For this purpose, a diagnostic system for the circulation dredge pump, dredge pump Expert, can be used. This system can effectively monitor the working state of the dredge pump body and equipment with a small number of sensing elements mounted on the dredge pump body. The various signals of the system are connected to each other and compared and adjusted with the stored intelligent experts.
