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, 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, 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. Both the internal and external parts can be used. The 05 pump station adopts a joint venture pump station and an imported pump station from Italy. If the speed requirement is too high, a joint venture customized pump station can be used to meet the ideal delivery requirements. The 06 oil cylinder and seals are made of imported components, solving the problem of unstable oil pressure for customers, The oil leakage problem of components 07. The oil cylinder is built into the platform 08. The heavy-duty steel wire rope wheel or weighted special chain ensures safety 09. The automatic insurance during the lifting process ensures vehicle safety 10. The synchronous device during the lifting process ensures that the vehicle may not overturn 11. The alarm setting before falling to the ground ensures the safety of the operator 12. The chain or steel wire rope fracture protection device 13. The hydraulic system pressure loss prevention protection device 14. The elevator special flat layer permanent magnet switch is selected, The leveling effect is good. 15. The distance between heavy and empty loads is small, and the leveling accuracy is high. 16. Standard elevator boards, LCD display call boxes, relevant wiring harnesses, and connectors are selected. Beautiful appearance, easy operation, visual display of the position of the elevator car on the floor, wiring harness connected using connectors,RuthTraction lifting platform, with automatic and manual options.
Firstly, adding chromium which steel should be chosen for production? Because there are many corrosion-resistant steel materials now nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
Emergency stop: Press the emergency button switch to raise or lower the machine.
Thermal aging stress relief is generally suitable for small workpieces, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!
The reduction gearbox, gearbox, external meshing gear and other parts, as well as the hydraulic oil are all carried out according to the requirements in the table.
The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line, and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
Where is good.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.
According to calculations, 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,RuthSelf propelled tracked scissor fork lifting platform, two support points should be taken on each side for time treatment.
The safety control voltage of 18 is selected with rolling guide shoes,RuthMobile lifting platform scissor fork type, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: 1. There is no need for a machine room above the shaft. 2. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. 3. The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, it can make the elevator emergency descend to the nearest floor position and open the door.
Heavy load capacity: protective plate form: 90° Or 180° Interchangeable configuration rocker working angle: 75° Drive method: hydraulic power unit drive or screw drive.
quality standard.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.
Ensure that power cables and electrical circuits are not damaged
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, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.
Ruth.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
The driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, during normal operation, it is prohibited to use the emergency stop switch to stop the platform.
