ShandongHydrauEach department's electric brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than 50%
The contact opening and closing of the travel switch of each safety device must be reliable, and the contact crater should be polished in a timely manner.
Shandong.When the motor connection of the elevator is incorrect, when a coil, coil group, or one phase winding group is connected in reverse, it can cause serious three-phase current imbalance and cause the winding to overheat.
Pay attention to checking each steel wire rope for broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance and upkeep of steel wire ropes should strictly follow the 85 regulations.
.When personnel enter the interior of the lifting platform for maintenance of outdoor elevators they must hang the elevator to prevent sudden lowering of the platform and causing casualties.
Working at heights is a common practice nowadays,Shandong12 meter hydraulic lifting platform, but it also has a certain degree of danger. So people invented hydraulic lifting platforms, which are more convenient to help people complete high-altitude operations. However, people should also pay attention when using hydraulic lifting platforms, otherwise they can easily malfunction, which may lead to serious consequences. So what are the common faults of hydraulic lifting platforms?
Each department's electric brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than 50%
The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder, the faster the lifting speed.
The current should exceed the rated current and even cause the motor to stop on its own. If the shutdown time is slightly longer and the power supply is not cut off, the winding will not only overheat severely, but also burn out. When a star connected motor is mistakenly connected into a triangle,ShandongHydraulic fixed lifting platform, or a motor with multiple coil groups connected in series into a branch is mistakenly connected into two parallel branches, it will cause the winding and iron core to overheat, and in severe cases, the winding will be burned out.
Familiarity with the usage process and without a doubt, this is the first thing to understand. There are two ways to understand it: first, carefully read the user manual provided by the manufacturer when the hydraulic lifting platform leaves the factory; The second is the equipment that needs to be installed. A professional installation technician will be dispatched to install the hydraulic lifting platform. After the installation is completed, relevant users will be trained on the operating process and safety precautions of the hydraulic lifting platform, and some maintenance matters in the future will also be explained; What should be paid attention to during the running-in period when using hydraulic lifting platforms? Check the wear of components. For newly processed and assembled components, there may be subtle deviations in shape and size that require a period of time for running-in. Therefore, it is necessary to pay attention to whether there is any rapid wear. If there is any, the manufacturer of the hydraulic lifting platform should handle it in a timely manner to avoid equipment failure; Work between the pins and bearings to ensure that they are not worn, and add some engine oil or grease appropriately; Confirm if there is any noise during the running-in period. If it is found that the hydraulic lifting platform is noisy during operation, there is no need to worry in the early stage. If there are no major problems, run it several times more. After the running-in, the noise will naturally disappear. However, if there is noise for a long time and no signs of fading, please make sure to promptly produce it and solve the problem; Regularly check if the components are loose. Before use, check if there are any signs of looseness in screws, nuts, retaining rings, oil pipe joints, please reinforce or replace them in a timely manner to avoid accidents.
Discount.What are the installation precautions for elevators? The folding fence and cage of the elevator should be cleaned of the foundation surface, a pad iron must be used below the screws to increase the force surface between the nuts and the floor to reduce the impact of the nuts on the floor; Insert steel plate shims of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite to ensure the verticality of each main pipe in both directions. After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and tighten the remaining anchor bolts; Install the buffer spring; Connect the other half of the fence to the front half with bolts; Adjust the verticality and tighten the anchor bolts as above, and release the brake on the motor inside the suspension cage. (For SC200/200 models, first install the suspension cage before installing the drive plate).
With the increasing demand for boarding bridges, mobile boarding bridge merchants are increasingly interested in using boarding bridges to provide customers with the appearance of hydraulic boarding bridges, and the demand for boarding bridges is also increasing. However, there are not many manufacturers of corresponding boarding bridges. Many boarding bridges are made of leather bags,ShandongHydraulic small lifting platform, and they do not produce them themselves, resulting in high prices. What is important is that they do not have a good understanding of the technology of car exhibition booths. When passing on direct customer technical requirements to the manufacturers, there are often deviations. Therefore, customers who purchase boarding bridges can directly find professional manufacturers. When choosing a boarding bridge, the first thing to consider is the range of use, frequency of work, utilization, rated weight, and other factors of the product, and then the after-sales service capability. As long as it is a fixed boarding bridge with good product quality, excellent performance, and complete equipment, it can be chosen at a reasonable price.
The product has a sturdy structure, a large load-bearing capacity, smooth lifting simple and convenient installation and maintenance, distribution box making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The editor will tell you about the level
Each box, etc. is usually kept clean, and dust on electrical equipment should be quickly swept away.
Statistics.What are the maintenance rules for the mechanical equipment of hydraulic elevators? The brakes of each mechanism should be regularly inspected and adjusted to ensure flexibility and reliability. On the friction surface, there should be no dirt present, and any dirt must be washed off with gasoline or thinner.
Check the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed± 10% of the motor does not rotate. Check the motor and circuit. The motor can be reversed to arbitrarily change the two phases in the three-phase line.
High altitude work requires the use of tool bags, and heavier and larger high-altitude work tools should be hung on stable components and cannot be placed randomly to avoid the occurrence of high-altitude falling accidents.
Shandong.Precautions for daily maintenance of hydraulic elevator: Check all hydraulic pipelines and joints of the hydraulic elevator. The pipelines must not be damaged, and the joints must not be loose. All joints must be tightened.
When encountering overheating in the electric motor during daily maintenance of the elevator, it is necessary to quickly park the car, remove obstacles, and then continue running. The motor bearings should be smooth and excellent.
