The environment mentioned here is mainly the impact of natural environment on electric gourds. The natural environment includes atmospheric environment, water environment, soil environment, geological environment, and biological environment. The environmental factors that have a deeper impact on electric gourd include humid environment, corrosive environment, dust environment, high temperature environment, and cold environment. The use of electric gourds in the above environment will have a certain impact on it, which may cause acceleration of accessories to be damaged. Electric gourds may be corroded or even scrapped directly, so they should pay more attention to their use in the above environment. Use electric gourds in a humid environment: under normal circumstances, when the humidity of the working environment is not more than 85%, the protection level of electric gourds is IP44, but currently requires more and more occasions that are required to adapt to large humidity. It requires the humidity to be 1000%. There are also many occasions. For example, the nuclear power plant also pollutes the nuclear dust of the nuclear equipment with high pressure water, and the protection level of the lifting equipment used must be improved. To this end, in the use of 85% to 100% humidity, electric gourd and electrical protection level should be IP55. In a humid environment, a preheating drying device should be added to the motor of more than 1OKW. The rain cover should be added to the electric gourds in the open -air operation. Use in a corrosive environment: reduce the chance of use in the corrosion environment, and try to avoid it. Special steel wire ropes such as galvanized and aluminum -plated with harsh environment with harsh environment and less exercise. The surface of galvanized or galvanizing on the atmosphere of these steel wire ropes will form a zinc hydroxide and aluminum hydroxide film, which can effectively prevent the corrosion of the steel wire steel wire rope of the wire rope. In addition, we must always maintain and apply oil. It is essential for the wire rope that is often in a sports state. New steel wire ropes generally contain 12 to 15 % of the oil, and the scrapped steel wire rope contains only 2.4 percent of the oil in the large part. 12.7 ～ 14.5 oil. The test shows that the stewed wire that occurs after the test after the test is about half of the non -oil. Use in the dust environment: the protection level of electric motors and major electrical appliances on the electric gourd should be improved accordingly. Under normal circumstances, the protection level of the electric motor and electrical appliances of the gourd -type crane should be IP44. According to the size of the dust, its sealing performance should be enhanced accordingly, that is, the performance of the seal, that is, Protection (mainly dustproof ability) levels should be increased accordingly to IP54 or IP64. Use in high temperature environments: The temperature control device such as thermistor should be buried on the electric motor winding and the case. When the temperature exceeds a certain value, the power off -power stop is protected, or a special electric fan is added to the electric motor to cool down. Use in a cold environment: timely clearing the track, ladder, and ice and snow on the stage to prevent slipping and falling.
