Description

Technical Field

[0001] The utility model relates to the technical field of vibration sensors, in particular to a vertical axial flow pump water guide bearing vibration sensor mounting base. Background Art

[0002] The vertical axial flow pump water guide bearing vibration sensor is a sensor used to monitor the vibration of rotating machinery, especially for the vibration monitoring of vertical axial flow pump water guide bearings. The main function of this sensor is to detect and measure the vibration of mechanical equipment, including parameters such as vibration speed, frequency, acceleration, etc., and convert these mechanical vibrations into electrical signal output for analysis and processing. In the application of vertical axial flow pump water guide bearings, the vibration sensor can be installed outside the machine to directly measure the vibration of the bearing seat, casing or structure.

[0003] When measuring, the vibration sensor usually needs to be installed on a base to ensure that it is firmly positioned and in close contact with the object to be measured. Existing vibration sensor mounting bases mostly use threaded rods and threaded holes to threadedly connect with the outer shell of the part to be measured to fix it. On the one hand, the connection between the mounting base and the vibration sensor becomes rusty after long-term use and is difficult to disassemble. On the other hand, when the mounting base is connected to the part to be measured, it cannot adapt to the different shapes of the part to be measured, which makes measurement more troublesome.

[0004] To this end, the utility model provides a vertical axial flow pump water guide bearing vibration sensor mounting base to solve the above problems. Utility Model Content
