In industrial production scenarios, environmental ventilation issues in injection molding workshops and machining workshops have long plagued enterprises.
In injection molding workshops, injection molding machines continuously release a large amount of heat during the process of melting plastics at high temperatures, and also produce trace amounts of plastic volatile odors.
In addition, the workshop space is usually large and equipment is densely arranged, which hinders air circulation and easily forms local high-temperature and stuffy areas.
This not only affects the comfort of workers’ operations, but may also affect the molding quality of injection molded products due to excessively high environmental temperatures. In machining workshops, due to the high-speed operation of various machine tools, the equipment itself generates a large amount of heat, and metal dust is produced during the processing process. The dust is easy to suspend and accumulate in the workshop. If ventilation is not timely, it will not only harm the respiratory health of workers, but also may adhere to the surface of precision equipment and processed parts, affecting processing accuracy and equipment service life.
When addressing these issues, selecting a suitable permanent magnet industrial HVLS Fan is crucial.
The following points should be noted during the purchase:
First, pay attention to the matching between the fan’s coverage area and the workshop size.
Based on the length, width, and height of the workshop, combined with the fan’s diameter and air flow coverage, ensure that a single fan or multiple fans can fully cover the operation area and avoid ventilation dead corners.
Second, attach importance to motor performance.
Prioritize the selection of high-efficiency and energy-saving permanent magnet synchronous motors, which not only have low energy consumption, but also have the advantages of stable operation and low noise, reducing interference to the workshop production environment.
Third, check the quality and design of the fan blades.
The fan blades should be made of high-strength and lightweight materials, such as aviation-grade aluminum alloy. At the same time, a reasonable fan blade angle design can ensure that a large amount of air flow is pushed at a low speed, improving ventilation efficiency.
Fourth, consider installation conditions and safety protection.
The installation height and load-bearing structure of the fan must comply with the workshop building requirements, and complete safety protection nets, emergency shutdown devices, etc., should be equipped to ensure safe use.
Fifth, pay attention to after-sales service.
Choose brands with professional installation teams and complete after-sales systems to facilitate subsequent equipment maintenance and fault handling.
After installing permanent magnet industrial HVLS Fans, significant changes will occur in injection molding workshops and machining workshops, and work efficiency will be greatly improved.
In terms of environmental improvement, the fan pushes a large amount of air flow through low-speed and large-diameter fan blades, which can quickly take away the accumulated heat in the workshop. The perceived temperature in injection molding workshops is reduced by 4 – 6℃, and that in machining workshops is reduced by 3 – 5℃, effectively alleviating the problem of high temperature and stuffiness.
At the same time, the accelerated air circulation promotes the diffusion and discharge of injection odors and metal dust, significantly improving the workshop air quality. The workers’ operation environment becomes more comfortable, fatigue caused by high temperature and odors is reduced, and the attendance rate and work concentration are significantly improved.
In terms of production guarantee, the stable workshop temperature avoids product molding defects caused by temperature fluctuations during injection molding, improving the qualification rate of injection molded products.
For machining workshops, a good ventilation environment reduces the damage of dust to precision machine tools, lowers the incidence of equipment failures, extends the service life of equipment, and indirectly reduces equipment maintenance costs and downtime losses. In addition, permanent magnet industrial HVLS Fans have low energy consumption.
The power of a single fan is usually only about half of that of traditional industrial fans, which can save enterprises a large amount of electricity expenses in long-term use and has high cost-effectiveness.
To ensure the long-term stable operation of permanent magnet industrial HVLS Fans, daily maintenance is essential.
First, it is necessary to regularly clean the dust, oil stains and other debris on the surface of the fan blades, usually at least once a month, to prevent the attachment of debris from affecting the air flow pushing efficiency and the balance of the fan blades.
Second, check the operation status of the motor every quarter, including whether the motor temperature and noise are normal, and whether the motor terminal blocks are firm, to prevent failures caused by loose wiring.
Third, focus on checking the tightness of screws at various connection parts of the fan, such as the connecting screws between the blades and the motor, and the fixing screws between the fan body and the installation bracket.
Finally, regularly check the safety protection devices, such as whether the emergency shutdown button is sensitive, to ensure that the equipment operates in a safe state.
In conclusion, permanent magnet industrial HVLS Fans can effectively solve the environmental ventilation problems of injection molding workshops and machining workshops, bringing significant work benefits to enterprises. With reasonable selection and daily maintenance, they can play a role stably for a long time. It is recommended that more similar factories actively install and use them to improve the production environment and enhance operational efficiency and economic benefits.
