Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering equipment technology, and in particular to a dynamic balance calibration device for a slurry pump base. Background Technology

[0002] Slurry pumps are important industrial conveying equipment, widely used in mining, metallurgical smelting, power generation, and other fields to transport suspended liquid media containing high concentrations of solid particles. The slurry pump base is the fundamental support structure of the pump unit, playing a crucial role in fixing and supporting the pump body, and affecting the operational stability of the pump unit. Especially when conveying high-concentration, highly abrasive slurries, the dynamic balance performance of the base structure is a vital factor for the long-term stable operation of the slurry pump. Good dynamic balance performance can reduce pump vibration, lower noise, extend the service life of key components, and ensure efficient and reliable operation of the slurry pump under complex working conditions.

[0003] Most calibration methods rely primarily on manual experience and simple tools, such as static calibration using a level. However, these methods cannot detect dynamic imbalances caused by uneven mass distribution of the slurry pump base during operation. When the slurry pump operates at high speed, dynamic imbalances in the base can lead to pump vibration and noise, affecting not only the equipment's efficiency but also accelerating the wear of components, reducing the equipment's lifespan, and potentially causing safety accidents. Existing calibration devices are mostly complex in structure, cumbersome to operate, and have limited calibration accuracy, making it difficult to meet the requirements of modern industry for efficient and stable operation of slurry pumps. Therefore, this application proposes a dynamic balancing calibration device for the slurry pump base to address this technical problem. Utility Model Content

The motor 4 is a variable frequency drive motor, which drives the drive shaft 21 and the half-shell base 7 to rotate through the coupling 24. According to the actual operating speed range of the half-shell base 7, the speed of the motor 4 is adjusted to make the half-shell base 7 rotate at different speeds, simulating the actual operating conditions of the slurry pump.

A triaxial accelerometer 16 detects the acceleration changes of the half-shell base 7 during rotation, obtaining the frequency and amplitude information of the vibration. A displacement sensor 15 detects the displacement changes of the half-shell base 7 in the vertical and horizontal directions. After detection, the data is transmitted to the control terminal 3. Then, the half-shell base 7 is connected to the left end of the support column 9. A robotic arm 8 performs multiple processing operations on the half-shell base 7. The robotic arm 8 has multiple degrees of freedom and can precisely control the milling cutter to reach the corresponding position for processing based on the imbalance position information given by the data processing system. Metal shavings generated during milling are collected using recycling bin 11 to maintain a clean working environment and prevent shavings from affecting equipment operation. After processing, the semi-shell base 7 is placed on the side platform 18 and inspected again by laser scanner 12. Laser scanner 12 performs high-precision, rapid three-dimensional information acquisition of the appearance of the semi-shell base 7. If it passes inspection, it can be used. If it fails, it is processed again by robotic arm 8. Combined with the precise calculations of control terminal 3, the magnitude, position, and phase of the imbalance of semi-shell base 7 can be accurately determined, achieving precise calibration of its dynamic balance and effectively reducing vibration and noise during operation.
