The cleaning oil for the hydraulic system must use hydraulic oil of the same brand as the system used, with an oil temperature between and ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more. After each cleaning,According to GB/T-, 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,MacaoGuide rail type lifting platform Lifting platform, 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.When disassembling the hydraulic oil tank filler cap, filter cover, 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.B é tar é Oya,Ensure that the small gear and pressure wheel are securely fastened on the drive base plate, and check the fixing condition of the drive base plate boltsAll connecting shafts must have split pins and be sufficient.When disassembling the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts, first remove the soil around the tank cap.

Organize, remove rust and repaint the structural components such as the suspension cage and guide rail frame for corrosion, and reinforce the severely corroded load-bearing membersThe selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T-, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.Ensure that the small gear and pressure wheel are securely fastened on the drive base plate, and check the fixing condition of the drive base plate boltsDesign brand,Drop test to check if the braking interval of the safety governor meets the requirements of the rules. Equipment transfer maintenance: Check the coupling between the electric motor and the worm gear reducer, and dismantle the gearbox. Clean all components and seals, replace excessively worn and deformed parts and smooth oilThe frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit is mainly composed of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation, all the eccentric roller shafts of the lifting cage and driving mechanism are loosened or adjusted to a large eccentricity. The lifting cage and driving mechanism are installed in the guide rail frame respectively, and the two are connected. Starting from adjusting the driving mechanism, power on the suspension cage to lift it m above the ground or detach it from the ground buffer spring (or support). The adjustment and sequence are as follows: . Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to ensure that the installation plate surface of the driving mechanism is perpendicular to the horizontal plane, and ensure that the upper and lower pendulum wheels evenly guide the rails at the same time. Use your hand to move each wheel body and check if it evenly presses the rails; . Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting, use a feeler gauge to measure the side clearance to .; Between .mm, each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly, adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand, it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of .-. ram with the guide rail; . Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator, the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the operation of each roller, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in appear on the surface of the gear rack,Macao10 ton mobile boarding bridge manufacturer, it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time, the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the spots reaches more than % of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracket
