Description

Technical Field

[0001] The utility model relates to the field of motor detection, in particular to an axial flow pump motor installation balance integrated calibration device. Background Art

[0002] In agricultural irrigation systems, the axial-flow pump-motor combination is the core device for transporting water resources. The axial-flow pump-motor draws water from the source and then delivers it to various areas of the farmland through pipes or channels. It provides sufficient power, enabling the axial-flow pump to lift and transport water at a specific flow rate and head, ensuring adequate irrigation water for crops. For example, in large irrigation areas, the axial-flow pump-motor can operate continuously, supplying water to large areas of farmland, ensuring crop growth and increasing agricultural yields.

[0003] In many fields, such as industrial production and water conservancy projects, the proper functioning of axial-flow pump motors is crucial to the stable operation of the entire system. To ensure the performance and reliability of axial-flow pump motors, integrated installation and balancing verification equipment has emerged. These verification devices are designed to accurately verify the balance of axial-flow pump motors during installation, preventing motor vibration, increased wear, and potential failures caused by imbalance.

[0004] The existing axial flow pump motor installation balance integrated calibration equipment has obvious limitations. Among them, a prominent problem is the inconvenience of calibrating axial flow pump motors of different lengths. Most of the existing calibration equipment is a fixed structure designed according to the specifications of axial flow pump motors of specific lengths. This structure cannot effectively adapt to axial flow pump motors of different sizes. When the axial flow pump motor is longer, the supporting components of the calibration equipment may not be able to provide sufficient support length, resulting in part of the motor being suspended in the air. When the motor is shorter, positioning and fixing it on the existing equipment becomes a problem, and it may also cause unnecessary extrusion or damage to the motor itself, thereby greatly reducing the efficiency of motor calibration.

Then, the elastic action of the spring recovery allows the card block to be connected and fixed with the new card slot, thereby realizing the tightening of the belt, effectively preventing the problem of inaccurate test results due to too loose a belt, and improving the accuracy of the test.

After the construction of the axial flow pump motor body 2 is completed, the inspection work can be started. At this time, the motor 2 13 is started, and the connecting seat 16 is fixedly connected to the motor 2 13.

The vibration displacement generated by the axial flow pump motor during operation can be measured by the vibration sensor 19. The size of the displacement can reflect the amplitude of the motor vibration. A larger displacement may mean that the motor is unbalanced, misaligned or has other faults.

[0029] Reference Figure 4 - Figure 5 , a moving block 17 is fixedly connected to the lower surface of the connecting seat 16, and the moving block 17 can be driven to slide inside the workbench 1 through the connecting seat 16, and the sliding setting of the slide 18 on the outer side of the moving block 17 allows the moving block 17 to slide stably along the slide groove 3 25 through the slide 18.

The vibration sensor 19 can measure the vibration displacement generated by the axial flow pump motor during operation. The size of the displacement can reflect the amplitude of the motor vibration. A large displacement may mean that the motor is unbalanced, misaligned or has other faults.

[0032] The spring 21 is pressed and contracted by the block 22 until the belt 12 is pulled to a suitable length and the block 22 slides to the new slot 26.
