KessleyOutdoorThe 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.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, 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.
Kessley.The solenoid valve on the motor should not be adjusted randomly. The solenoid valve is pre adjusted before leaving the factory, and random adjustment can easily cause internal pressure to increase or decrease, which in severe cases can shorten the service life of the motor.
Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
.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.
The 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.
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, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor 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.
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, 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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Excellent service.The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to user requirements, with a load of up to 10 tons.
'Before installing the elevator bearings, we should never open the packaging prematurely. This can easily lead to premature bearing contamination, which can lead to premature bearing damage. In addition, when installing, it is necessary to ensure that the device environment is clean and not to bring iron filings,KessleyFixed guide rail lifting cargo elevator, dust, as even some small dust,',KessleyElectric cargo elevator, If it continues for a long time, it will also affect the running-in between bearings, 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.'.
Kessley.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.
