The automobile manufacturing industry occupies an important market share, and at the same time, as a powerful engine of the global economy, the automobile industry affects the development of the world economy. The automobile manufacturing industry has driven the development of many related industrial chains, and the scale of automobile manufacturers is also expanding. The future development of the automobile industry tends to be specialized, intelligent, digital, networked, and electrified, which is inseparable from the support of a large number of talents and technologies. Automakers' all-around care for employees is also one of the irreversible trends. The breakthrough and in-depth cooperation between industrial fans and the auto manufacturing industry have promoted the green development of the auto industry and the working environment of employees.
Most of the interiors of automobile manufacturing plants are steel structure workshops with large spans, wide-area, and high spaces. The overall automobile manufacturing plant can be roughly divided into four production workshops: stamping, welding, painting, and final assembly. At the same time, there are chassis, body, painting, and final assembly production lines and inspection lines. Due to the lack of ventilation and exhaust facilities in many factories, coupled with the high-intensity and long-term operation of machinery and equipment in the stamping and welding workshops of automobile manufacturers, excessive heat is released. Due to the heat flow, the employees were enveloped by the high-temperature heat flow, and the body scorching was unbearable. Especially when the high temperature hits in summer, the employees are sweating profusely and cannot work normally with peace of mind. Employees are distracted, productivity is reduced, and accidents are prone to occur. Freon, a foaming and defoaming agent used in plastic castings of automobiles, and lead-based paints and paint solvents used in automobile painting, dissipate a large amount of irritating and harmful gases, which exist for a long time and have high concentrations. Employees will have difficulty breathing and bring health problems.
It is very important to provide employees with a green and healthy working environment in automobile manufacturing plants, especially in welding workshops. Because the welding process will produce chemical harmful pollution, mainly welding fumes and harmful gases. The smoke and dust are in the form of fragments, with high viscosity and a large amount of dust; the harmful gases are ozone, nitrogen oxides, carbon monoxide, fluoride, or chloride generated under the high-temperature arc of welding. If these are inhaled by employees in large quantities, symptoms such as coughing, chest tightness, shortness of breath, sputum, and hemoptysis will occur. Severe employees may suffer from occupational diseases such as pneumoconiosis, fluorosis, and manganese poisoning.
Faced with such severe and severe problems, automobile manufacturing factories are indeed urgently seeking solutions to improve the internal environment of the factories. As an industrial large HVLS ceiling fan manufacturer, our GX Fan company contacted the factory after learning about this demand, communicated in detail about the factory structure, area, workshop, machinery and equipment, and employee work areas, and formulated a set of reasonable ventilation and cooling solutions for it. The industrial large HVLS ceiling fans were successfully installed on the steel structure beam inside the automobile factory, and the key installation was carried out in the area where the employees operate the machine to achieve post air supply. The streamlined design of the large HVLS ceiling fan's blades increases the coverage to a radius of 22 meters, creating a cone of airflow that reaches body height. The large air volume covers the entire body of the employee, the wind speed is stronger and more uniform, and the airflow "hole" in the center of the ordinary fan is eliminated; Running at a wind speed of 1 m/s to 3 m/s quasi-natural wind can increase the cooling feeling of employees, and through airflow circulation and airflow dispersion, the ambient temperature around employees can be reduced by 4℃ to 6 ℃.
While helping to cool employees, energy-efficient industrial large HVLS ceiling fans also help improve air circulation inside the car manufacturing plant. The diameter of the fan is 7.3 meters, and the rotation speed is 40-55 rpm. By pushing the airflow, a cone-shaped airflow is formed to circulate downward, and the fresh air in the upper part of the car manufacturing plant with low carbon dioxide concentration is pushed to the bottom, and then smoke and harmful gases are discharged through the doors and windows. At the same time, it can supplement fresh air for the factory, reduce the concentration of smoke and harmful gases, and provide a comfortable and healthy working environment for employees; in addition, industrial large HVLS ceiling fans can save energy and reduce carbon emissions, and achieve a green and benign development of the environment. What’s more, because of the improvement of the entire workshop environment, employees will improve their work efficiency in such a comfortable environment. Coupled with saving electricity bills, the car manufacturing plant can also save production costs while being a green production site.
