Description

Technical Field

[0001] The utility model relates to the technical field of pump group monitoring, and more specifically, to a pump group health monitoring device for an intelligent water plant. Background Technique

[0002] The pump group is an important part of the intelligent water plant, and the pump group is mainly used for various purposes such as fire fighting, water supply, and pressure stabilization. Therefore, it is very important to monitor the pump group to ensure the safe and reliable operation of the pump group, prevent failures, ensure production safety, and extend the service life of the pump group.

[0003] For this reason, in the prior art, the health of the pump group is monitored through a vibration sensor. The vibration sensor is arranged on the outer shell of the pump group to monitor the vibration frequency and amplitude of the pump group, and then the monitoring data is fed back to the monitoring terminal, so as to detect problems such as wear, imbalance, looseness of the pump group bearing and impeller damage. However, during the use of the vibration sensor, the traditional fixed installation has no insulation design at the bottom, which will generate electromagnetic interference to it and affect the accuracy of its monitoring results.

[0011] Furthermore, for the present utility model, the suction force of the magnetic suction seat is 10 - 20 kg to ensure the adsorption effect.

[0012] Furthermore, for the present utility model, the length of the threaded rod is greater than the depth of the internal threaded rod to improve the connection stability.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
