Fast door, a high-quality food factory PVC fast door, Hongfa automatic door

Description :

　　Due to frequent opening and closing of fast doors in daily work, there may be some minor issues after prolonged use. Choosing a high-quality manufacturer and paying attention to daily maintenance can improve the service life of the product. Next, let's take a look at the repair methods for quick rolling shutter doors.

　　Regular inspections can prevent accidents from occurring. Due to the simple composition structure of the quick door, the overall condition of the product can be observed visually. Mainly observe whether the door body lifts and opens smoothly. If the fast door is not used for a long time, regularly test and run the fast door to check whether the switch button is normal, the electrical control box indicator signal, etc.

　　More detailed maintenance can be divided into frequency converter maintenance and motor maintenance. Regularly check whether there are foreign objects blocking the air inlet of the frequency converter, and clean the dust in the cooling air duct of the filter every month. Inspect the corrosion of wires and insulators annually. If there is, wipe it with alcohol in a timely manner. Check if bolts, screws, and inserts are loose. Whether there is a short circuit to ground and phase to phase resistance in the output and input reactors should be greater than tens of megaohms under normal circumstances. Test the stability of the output circuit voltage of the opening and closing power supply, such as 5V, 12V, 15V, 24V, etc., and check for spark marks on the contactor contacts. If the situation is serious, it is necessary to update the new contactor to its original capacity. Confirm that the control voltage is correct, conduct a sequential protection action test, confirm that the protection display circuit is normal, and confirm that the output voltage of the frequency converter is balanced when running alone.

　　Fast doors have been continuously developed in recent years and have been applied in various industries. So, how can fast doors achieve energy-saving effects? Below, the editor will answer the key to energy-saving for fast doors.

　　The most important aspect of energy-saving for fast doors is to provide them with high strength, high air tightness, high water tightness, high precision, and excellent thermal and sound insulation performance. The key to energy-saving of fast doors is to have high insulation and thermal insulation performance while meeting their functional requirements. For offices and production workshops, using air conditioning for cooling in summer and heating or electric heaters for heating in winter has become a necessary condition. The energy consumption involved is a significant expense for businesses. The sealing and insulation performance of the fast door height effectively prevents air loss, and the lifting speed of the fast door is 0.7m/s-2.1m/s, which isolates air by quickly opening and closing.

　　In the cold winter weather, there is a large temperature difference between indoor and outdoor areas. If the air tightness is not high, it can cause a pressure difference between indoor and outdoor air. Outdoor cold air enters the room through gaps, causing severe fluctuations in room temperature, affecting the indoor environment and consuming a large amount of heat energy. This phenomenon is called cold air infiltration. In hot summer weather, outdoor high temperature weather, and indoor air conditioning cooling, the hot air generated by air flow enters the room through gaps, resulting in an increase in cooling energy consumption. Whether it is cold or hot, the temperature difference between indoors and outdoors will lead to an increase in energy consumption when the air tightness is poor. Therefore, the air tightness performance of fast doors is an important measure for energy conservation.

　　Another thing is the insulation effect of the quick door. Two bottles containing hot water at the same time, the open one cools faster than the sealed one, while the glass bottle cools faster than the plastic bottle. The latter phenomenon is manifested in the differences between materials. As long as there is a temperature difference, heat transfer cannot be avoided, and the main pathways of heat transfer are convection, conduction, and radiation. The sealing performance, material performance, and smoothness of surface technology are respectively evaluated

　　Reducing heat loss through flow, conduction, and radiation achieves energy-saving effects. Our door curtain material is imported industrial polyester fiber cloth, high-strength and environmentally friendly polyester fiber, good insulation, double-sided polymer coating, smooth and beautiful. By quickly opening and closing, it has excellent energy-saving effects.
