South BostonTiVibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.

Organize, remove rust, and repaint structural components such as suspension cages and guide rails for corrosion, and reinforce load-bearing members with severe corrosion
The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.
technological innovation.Drivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. flat
Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.
Jinchuang lifting platform product feature 01 is mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and a lifting height of 1-25 meters, a guide rail elevator, also known as a hydraulic elevator, can be installed indoors and outdoors. The lifting height is high and uses a side mounted oil cylinder, which runs smoothly, has low noise, is convenient for maintenance, and has a long service life. In case of a power outage, manual emergency descent can be used, which is safe convenient, fast, and practical. The pit depth is generally 15cm-30cm, and the top layer height is not affected, The 04 pump station can be customized according to the on-site environment, suitable for 2-3 floors of steel structures or concrete factories.

Recommendation and consultation.Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Check if the usage period of the speed limiter has expired. If it exceeds the usage period, it is necessary to send it to a qualified professional unit for inspection and calibration. What are the functions of the lifting stage device?
According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.
South Boston.The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion.

Low power consumption: When the hydraulic elevator descends,South BostonMobile scissor type lifting platform, it is driven by the pressure generated by its own weight, which greatly saves energy.
However, large welded structural components have the characteristics of complex morphology, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.
