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, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

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.

Fort Worth.When loosening occurs, newly processed and assembled components have deviations in geometric shape and fitting dimensions. In the early stages of use, due to alternating loads such as impact and vibration, as well as factors such as heat and deformation coupled with rapid wear and tear, it is easy to cause the previously fastened components to loosen.

Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight,Fort WorthFixed guide rail lifting platform, which greatly saves energy.

.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. Apply engine oil, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating, hot plating spray plating, etc., to coat the surface of steel with a layer that is not easily corroded

Vibration 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.

Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.

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.

The surface of each part of the brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than 50%.

When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.

plan.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.

Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.

The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity,Fort WorthSelf propelled curved arm lifting platform, so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, can work across obstacles, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm, and the scope and space of operation are not affected.

Sales Department.However, large welded structural components have the characteristics of complex morphology, 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,Fort WorthMobile scissor fork lifting platform, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.

When disassembling the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts, it is necessary to avoid dust during the system oil passage. The disassembled parts must be thoroughly cleaned before opening. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap. After loosening the tank cap, remove any remaining debris from the joint area (do not rinse with water to prevent water from seeping into the tank). Only after confirming cleanliness can the tank cap be opened. When using materials and hammers materials that do not remove fiber impurities and specialized hammers with rubber attached to the surface should be selected. Hydraulic components and hydraulic hoses should be carefully cleaned, dried with high-pressure air, and then assembled. Choose a well packaged filter element (the inner packaging is damaged, although the filter element is intact, it may also be unclean). When changing the oil, clean the filter at the same time. Before installing the filter element, carefully clean the bottom dirt inside the filter housing with materials.

Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.

Fort Worth.Outdoor guide rail lifting platform, mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and an elevation of 1-25 meters, guide rail elevators, also known as hydraulic elevators, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders, ensuring smooth operation, low noise, convenient maintenance, and long service life. In case of power failure, manual emergency descent can be used, convenient, fast, and practical. The pit depth is generally 15cm-30cm. Professional elevator manufacturers have high pressure resistance, good waterproof performance and fire and high temperature resistance, Strong overload capacity, corrosion resistance, long service life. The top layer height is not affected, and can be customized according to the on-site environment. It is suitable for 2-3 story steel structures or concrete factories, and can be used both internally and externally.

Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.

Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
