DundockScissorNow with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition,DundockGuide rail type outdoor lifting platform, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
Emergency stop: Press the emergency button switch to raise or lower the machine.
Dundock.Check the protective cable condition of the cable guide frame
When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.
.Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
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.
According to calculations,DundockGuide rail type lifting platform, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
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
Production department.The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and the strength requirements of the shaft are low, 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 it can make the elevator emergency descend to the nearest floor position and open the door.
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
The second method is the protective layer method, 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
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,DundockHow much is the guide rail hydraulic lifting platform, changing the internal structure of the metal to prevent rust.
Product range.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.
Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace it
Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, the rocker will automatically prevent wheelchair platform.
