XilinhotFixed 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, 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.
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.
Xilinhot.When using the four legs should be firmly supported on a solid ground (subject to the fact that the walking wheel is about to leave the ground). Sleepers can be used when necessary.
To ensure excellent power supply at the installation site, install a separate distribution box. When using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, the clothes will repeatedly slap the car paint, especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
Guide rail elevator (also known as cargo elevator) is a non scissor fork type hydraulic lifting platform, mainly used in industrial buildings, restaurants, restaurants, warehouses, docks, workshops, and other places where vertical cargo handling is required between two or more floors. The low height is particularly suitable for sites that are not suitable for digging pits on site. What issues should we pay attention to in these places where elevators are used?

where.The water cooling of hydraulic stations is generally tubular water cooling, and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the type selection calculation is performed when the flow can be satisfied. Therefore, the two types of cooling are different and there are significant differences.
