St.PetersburgGThe motor winding is short-circuited. When a short circuit fault occurs in the motor winding, the short circuit current is much larger than the normal working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox, gearbox, external meshing gear, and other parts of the equipment, as well as the hydraulic oil, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables,St.Petersburg10 ton lifting cargo elevator, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.
St.Petersburg.As we all know now,St.PetersburgSmall cargo elevator, elevators and lifting platforms have been widely used in recent years to solve the problems we encounter in daily life. Because working at heights is a high-risk profession that requires the assistance of auxiliary tools to complete certain tasks, the use of elevators is undoubtedly emerging in the domestic machinery market and has been vigorously developed.
'Using the elevator is not about maintaining and overhauling the equipment after it has failed. It is important to maintain the equipment in accordance with the correct maintenance and overhaul. First, do the preparatory work to eliminate all possible fault problems and accidents. I hope that today's summary of knowledge points by the editor can help everyone.'.
.Does the cleanliness of the hydraulic station have relevant rules and requirements?
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
Usage: Scissor fork type fixed lifting platforms are mostly used for goods transportation between height differences in production lines, loading and unloading materials, adjusting the working height during workpiece assembly, lifting components during assembly of large equipment, matching storage and loading sites with forklift trucks and other transportation vehicles for rapid loading and unloading of goods, vehicle lifting, fixed three-dimensional parking, and other places.
Incorrect connection of the elevator motor When a coil coil group, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
As we all know now, elevators and lifting platforms have been widely used in recent years to solve the problems we encounter in daily life. Because working at heights is a high-risk profession that requires the assistance of auxiliary tools to complete certain tasks, the use of elevators is undoubtedly emerging in the domestic machinery market and has been vigorously developed.
Goods should be stacked well on the platform, and should not be tilted. When the goods elevator is lifting or lowering beyond the scope of the platform, no one should stand around to watch.
Create brilliance.Connect the motor to the elevator naturally. During connection it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
Many people believe that the mechanical strength of the elevator itself is relatively high when using the elevator, so the installation method specified in the manual is not strictly followed during the installation process. However, this can lead to increased wear of parts and inflexibility in operation. In addition, it is necessary to pay attention to the installation precautions corresponding to the working environment and not be careless. Correct installation, use, and maintenance of the elevator are important steps to ensure the normal operation of mechanical equipment. Therefore, when installing the elevator, please be sure to carefully assemble and use it in strict accordance with the following installation and use related matters.
Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found, go to a professional beauty shop for processing in a timely manner.
Is the water cooling and air cooling of the hydraulic station the same?
Word of mouth recommendation.Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Manual hydraulic platform classification: Manual hydraulic lifting platform vehicles can be divided into manual hydraulic handling platform vehicles, manual hydraulic stacking platform vehicles, and manual hydraulic shear type platform vehicles.
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
St.Petersburg.Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions scratches, regularly inspect the engine compartment lid and surrounding areas, and once found, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
Frequently check for water accumulation and humidity. It is inevitable for aerial vehicles to drive in rainy and snowy weather, or muddy roads. The bottom and some gaps and indoor floors are prone to sludge accumulation. If the owner does not clean them in a timely manner, this can cause moisture to hide. Therefore, activities in the outer edges of wheel hubs, doors, bottom corners of tree trunks,St.PetersburgConstruction site lifting cargo elevator, key holes, and wiper brackets, as well as other areas, should be regularly inspected, and the drainage holes in the doors and various parts should be kept unblocked to ensure that the car seat covers, such as humidity, carpets, and floors, prevent rust from forming parts.
