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, fully drain the system while the oil is hot.The 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, 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, 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.portland ,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 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 if the orientation of the upper and lower limit blocks on the guide rail frame is correctGodollo,Regularly check whether the operation of each mechanism is normal and whether there is any noise. If any faults are found, they must be promptly eliminated.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 lifting stage can provide real-time information on the operation of the entire vehicle, avoiding relying solely on the experience of operators to coordinate with each other, and improving the reliability and safety of the system. The definition of safety zone is very important because the lifting stage has a large range of movements, and it must be accurately calculated. The lifting stage has two structurally separate systems, the ground turntable and the high-altitude work bar. However, for various movements on the vehicle, it is also an interconnected system, which needs to consider the priority of operation, system redundancy, and safety assurance of actions.

Manganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.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,portland Hydraulic aluminum alloy lifting platform, and the layout principle is: when the aspect ratio of the component is greater than , two point supports can be used; When the aspect ratio is close to , it is advisable to use or -point support.Please refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brakebuild,What are the functions of anti rust primer for warehouse cargo elevators?Check the fastening status of the wall bracket, support rod, and bolts and retaining rings between the lifting cargo elevator and the bridge. If they are loose or displaced, they should be checked and tightenedAttention: Abnormal meshing of gear teeth should be avoided: uneven rolling of the rollers should be avoided; Avoid diagonal orientation of the guide rollers; It should be avoided that the guide rollers are kept at the same time for a long time; The above abnormal phenomena can lead to rapid wear and even scrapping of gears, racks, rollers, and guide rails. If adjusted more carefully, it will be more beneficial for the service life of the elevator.

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 %.Where can I find it?,portland Tractive mobile elevator,Quarterly maintenance: Check the items checked each monthThe 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.
