Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, or when several coil groups are connected in series into a single branch,JinghaiIndustrial cargo elevators, the motor is mistakenly connected into two branches in parallel, and in severe cases, the windings will be burned.
Jinghai.When working in a hot environment, pay attention to heat dissipation.
The anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
.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.
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.
After the goods are transported, clean the platform.
Before installing the elevator, confirm whether the motor and the elevator are intact, and strictly check whether the dimensions of each part connecting the motor and the elevator match. Here are the dimensions and fit tolerances of the positioning boss, input shaft, and elevator groove of the motor.
Failure Analysis of Mobile Elevator
Knowledge popularization and superior performance of scissor fork type fixed lifting platform: equipped with safety devices to prevent overloading of the lifting platform; Equipped with a protection valve to prevent hydraulic oil pipe from cracking; Equipped with an emergency lowering device for sudden power failure; The doors of the upper and lower floors are equipped with safety devices that interlock with the system.
Information recommendation.In addition to having a fixed mode, there are also types of mobile elevators. As the name implies, it is a combination of lifting equipment and on-board systems. This type of lifting equipment is very flexible to move,JinghaiFreight elevator lifting, and of course, it is better to use it. For example, and stations or stadiums may also be equipped with such equipment, as it can be moved by itself, The scope of work is not limited to a certain place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to send billboards or staff to a designated height for work. This type of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive to achieve a specified height. The electric mode is driven by a motor or tooth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current,JinghaiHigh performance elevator, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
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.
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
High value.Hydraulic lifting platforms are widely used in factory maintenance or one of the parallel branches is open circuit, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
Make sure to add butter twice a month to the transmission assembly where the grease fitting is located. For parts where butter cannot be added, it is necessary to dredge the oil circuit or replace the grease fitting until butter can be added, otherwise it is prohibited to use the equipment.
Systems: explosion-proof electronic control system, remote control system, PIC system.
Jinghai.Test the goods elevator every day to see if it can operate normally.
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, Transformation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.
