Explosion-proof electric hoist is composed of multiple parts, of which the motor is the core component of the entire electric hoist, especially the explosion-proof hoist requires that the motor must be explosion-proof whether it is level three or four, then the selection and How is it different from other gourds?
等特点，除此之外防爆电动葫芦所需的电机还要适应不同的工作环境、温度及湿度问题。 When selecting an explosion-proof hoist motor, you must choose according to the weight of the hoisting weight. The main parameters of the motor are the characteristics of the number of contacts, the number of lifting times, and the high-intensity cycle work . Working environment, temperature and humidity issues.
As an explosion-proof electric hoist manufacturer , remind you that in addition to paying attention to the above issues when selecting a motor, you must also choose a very good lifting torque and overload capacity. The maximum safe speed of the motor can reach about 2.5 times the rated speed to ensure the motor. Quality and the quality of hoisting hoist.
The load test of explosion-proof electric hoist is in order:
次。 1. Start the explosion-proof electric hoist hoisting mechanism first to perform the no-load lifting operation to make the trolley run back and forth throughout the whole process. This no-load trial operation is not less than 3 times.
2. Park the trolley in the track span, and gradually increase the load for lifting trial operation, until the trolley is fully traveled on the track after being added to the rated load.
应无失稳现象，然后卸去负荷，将小车开到跨端或支脚处，检查电动葫芦金属结构且应无裂纹、焊缝开裂、油漆脱 等缺陷。 3. Lift the load 1.25 times the rated lifting weight without impact. At a height of 100 ~ 200mm above the ground, the suspension stay time should be no less than 10min, and there should be no instability. Then remove the load and drive the car. At the span end or at the foot, check the metal structure of the electric hoist and it should be free of defects such as cracks, cracks in welds, and paint peeling .
4. Determine the actual camber of the main beam, which should be greater than 0.75 / 1000mm.
葫芦及负荷静止后，测出其上拱值，此值与第四项结果之差即为电动葫芦的静刚度，电动葫芦的静刚度，应在主梁 跨度中部s/10的范围内丈量。 5. When checking the static stiffness of the explosion-proof electric hoist track, fasten the trolley to the middle of the track, and lift the load of the rated lifting weight, 200mm from the ground. After the electric hoist and the load are stationary, measure the upper arch value. The difference between the fourth results is the static stiffness of the electric hoist. The static stiffness of the electric hoist should be measured within the range of s / 10 in the middle of the main beam span.
少于1h，各机构动作应敏捷、平稳、可靠，安全保护、联锁装置和限位开关的动作应正确、可靠。 6. The dynamic load test operation should be performed over the full stroke length. The lifting weight should be 1.1 times the rated lifting weight. The cumulative start-up and running time should not be less than 1h for the electric hoist . The movements of each mechanism should be agile, stable, reliable and safe The actions of protection, interlocking devices and limit switches should be correct and reliable.
