| 在粉尘环境中，对防爆电动葫芦有特殊的防护要求，防护要点如下： I. in dust environment, there are special protection requirements for explosion-proof electric hoist, and the protection points are as follows: (1)起重机上的电动机和主要电器的防护等级应相应提高，通常情况下葫芦式起重机用电动机及电器的防护等为IP44，根据粉尘程度的大小，应相应增强其密封性能，即防护(主要是防尘能力)等级成相应提高为IP54或lP64； (1) the protection level of the motor and main electrical appliances on the crane shall be increased accordingly. Generally, the protection level of the motor and electrical appliances for the hoist crane is IP44. According to the dust level, the sealing performance shall be enhanced accordingly, that is, the protection level (mainly dust-proof ability) shall be increased to IP54 or LP64 correspondingly; (2)应采用闭式司机室进行操作，以保护司机的人身健康。 (2) the closed cab shall be used for operation to protect the personal health of the driver. 二、在高温环境中，对防爆电动葫芦有特殊的要求，防护要点如下： II. In high temperature environment, there are special requirements for explosion-proof electric hoist, and the protection points are as follows: (1)电动机绕组及机壳上应埋设热敏电阻等温控蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 装置，当温度超过一定界限时，断电停机加以保护或在电机上增设强冷措施(通常为在电机上增设一专用电风扇)。 (1) temperature control devices such as thermistor shall be embedded on the motor winding and casing. When the temperature exceeds a certain limit, power off and stop for protection or add strong cooling measures on the motor (usually adding a special electric fan on the motor). (2)司机室应是闭式装有电风扇或安装空调的司机室。 (2) the cab shall be a closed cab equipped with electric fan or air conditioner. 三、在施工场地中，对防爆电动葫芦有特殊的要求，防护要点如下： III. in the construction site, there are special requirements for explosion-proof electric hoist, and the protection points are as follows: |
