Senteshydrauli
SentesFixed hyInstalling bearings for elevators may seem simple, such as: it is actually difficult to thrust bearings into the shaft pins when excessively installing them. However, sometimes, some people may think of using a hammer to hammer the bearings for convenience, and use brute force during installation. In fact, directly hitting the bearings with a hammer can cause significant damage to the bearings, which is the main reason for bearing damage and reducing the service life of the bearings. So when installing bearings, we must not go too far. Fortunately, we can place some soft cloth or cardboard on top of them before installing them.
Loosening: The motor fan makes a sound when it rotates. If the screws that fix the motor are loose, coupled with its own vibration, the motor collides with other components, resulting in a sound; The joints of each pin shaft are dry, lacking oil and there is hard friction between the iron parts, which not only damages the components but also produces abnormal noises. Therefore, the editor should emphasize again that timely maintenance and frequent refueling are important; If the hydraulic lifting platform does not rise, add gas, and then tighten it again; Hydraulic oil solidification: replace the hydraulic oil; Oil leakage: Check if there is any oil leakage at the interfaces of each oil pipe. If there is any oil leakage, replace it in a timely manner; Motor reversal: Check for wiring errors; (Manufacturers of hydraulic lifting platforms who do not understand electricity in a timely manner)
Sentes.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.
Outdoor elevators and factory cargo elevators are heavy lifting mechanical equipment. Outdoor elevators are used for transporting goods between floors of buildings and are specialized hydraulic cargo elevator products. They are mainly used for transporting goods up and down between various working floors; Vertical garage and car lift between garage floors. The hydraulic system of the product is equipped with anti fall and overload protection devices, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point operation.
.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.
The sinking of a cargo elevator is a phenomenon where the table surface drops due to gravity after a certain period of time when it rises to a designated position. Of course this problem is definitely abnormal. So how can we solve it? The first step is to identify the cause. Below, the editor summarizes the ultimate solution.
Do not adjust the solenoid valve on the motor arbitrarily. The solenoid valve is pre adjusted before leaving the factory, and random adjustment can easily cause internal pressure to increase or decrease. In severe cases,SentesElectric fixed hydraulic lifting platform, it can shorten the service life of the motor.
Familiarity with the usage process and without a doubt, 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, during the running-in period, 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, check if there are any signs of looseness in screws nuts, retaining rings, oil pipe joints, etc. If there are any, please reinforce or replace them in a timely manner to avoid accidents.
Hydraulic lifting platforms can be divided into: four wheel mobile, two wheel traction, car modification, car type, auxiliary self-propelled, and lifting heights ranging from a meter to 1 meter.
Before using the machine,SentesProduction hydraulic lifting platform, the staff should carefully inspect the hydraulic and electrical systems to ensure that there are no leaks or bare leaks before use.
Job description.The second is that the steel will have obvious thermal expansion effect at low temperature. Although this property of steel will be taken into account when designing and manufacturing hydraulic elevators, the environment is different after all. Under low conditions, the steel will have some unstable performance,SentesLifting hydraulic platform, such as hardness increase, toughness decline, etc. At this time, more attention should be paid to the maintenance of equipment to keep key parts to avoid dry grinding.
Regular inspection and maintenance, eliminating hidden dangers, and troubleshooting are beneficial for improving work efficiency, extending equipment service life, and ensuring the safety performance of elevators.
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 using, the four legs should be firmly supported on a solid ground (based on the walking wheel about to leave the ground), and sleepers can be used when necessary.
property right.High altitude work is now also very common, with high efficiency and reassuring safety. However, attention should also be paid to the installation of the elevator, otherwise there may be problems, and no one wants to see such a situation happen. What are the installation precautions for elevators?
Unscrew the screws on the dustproof hole on the outer side of the elevator flange, adjust the PCS system ring to align its side hole with the dustproof hole, and tighten the inner hexagon. Afterwards, remove the motor shaft key.
Regularly check the connection of each part of the hydraulic elevator, and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure, and all connecting shafts must have split pins and be sufficient.
Sentes.When using the distribution box, the electric leakage switch meets the requirements for construction elevators. If the fixed elevator installed is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
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.
