The door installed in the ultra-low temperature environment such as cold storage equipment and freezer is the cold storage door. This door not only has good heat insulation effect, but also needs good sealing effect. In this way, the overall environment can be kept constant. At present, we use professional cold storage door sealing strips to seal the cold storage door in actual operation.
Although the cold storage door sealing strip can not cool the environment, it can better isolate the internal and external environment and block the heat exchange between the internal and external environment. Moreover, this product is more convenient to use, and can be installed at one time.
Compared with other refrigeration equipment, it will not produce additional energy consumption in the working process, and the cost is also very low, which can better reduce the storage cost and cost for enterprises.
Using the cold storage door sealing strip can better seal the cold storage equipment and achieve better indoor refrigeration effect. This is very important for many manufacturers and enterprises.

Energy saving is important to make the door have high strength, high air tightness, high water tightness, high precision, excellent heat insulation and sound insulation performance. The key to energy saving of fast door is that it has high thermal insulation and thermal insulation performance on the premise of its application function. For office and consumer workshops, it has become a necessary condition to use air conditioning for refrigeration in summer and heating or electric heater in winter. The high sealing and thermal insulation performance of the fast door can effectively avoid the loss of air, and the lifting speed of the fast door is 0.7m/s-2.1m/s, which is isolated from the air through rapid opening and closing. In the cold weather in winter, the indoor and outdoor temperature difference is large. If the air tightness is not high, the indoor and outdoor air constitutes a pressure difference. The outdoor cold air passes through the gap and the room temperature shakes, which affects the room and consumes a lot of heat energy. This phenomenon is called "cold air infiltration"; In the hot summer weather, outdoor high temperature weather and indoor air conditioning refrigeration, the hot air generated by air activities passes through the gap indoor, which reduces the refrigeration energy consumption. Whether it is cold or hot, the temperature difference between indoor and outdoor will consume energy under the condition of poor air tightness. Therefore, the air tightness of fast door is an important measure of energy saving. The fast door adopts new high-frequency welding technology, fully automatic splicing and one-time forming, and the air bag cloth pocket is installed at the bottom of the door curtain, which can be sealed and separated from various uneven air. The guide rail is equipped with a brush to achieve a high sealing effect.

The fast door adopts double spiral turbine guide rail to make the door body run more quietly and stably. The bearing capacity is greatly strengthened, the friction is reduced, and the operation is faster; When rolling up, there is no contact, friction and wear between the door panel and the connecting piece. The switch is smooth and fast, which improves the service life of the door body. The guide wheel adopts shaft sleeve and Peek (polyether ether copper). This data can not produce molecular change at the temperature of - 60 ℃ and + 200 ℃, and the wear resistance is 10 times that of copper. It has self smoothing function and is mainly used in military in the United States. The outer surface of the hinge shaft is treated with QP, which can increase the self smoothness and corrosion resistance of the shaft, which is 3-5 times that of the galvanized shaft. The transmission shaft adopts retractable spline transmission shaft. This plan is applied to automobile transmission power. It is maintenance free for life, which can effectively reduce noise and is suitable for size deviation caused by metal molecule change caused by temperature change. Precautions: correct application methods and proper maintenance will help to prolong the service life of the fast door (once the product is installed, our technicians will set a reasonable lifting speed according to the size of the door body. Generally, it does not need to be adjusted by the customer. Please do not move without permission). The customer shall set the opening and closing speed of the fast door according to the practical needs. Otherwise, unnecessary energy waste and friction loss of transmission parts will be formed. As long as the request is met, try to lower the speed of the fast door, especially the larger door. It is helpful to maintain the longer service life of the frequency converter.

1、 Schedule of quick door:
1. Motor configuration: the configuration and performance of the motor directly affect the opening speed and service life of the fast door. If consumers buy low-quality fast door motors, they may have problems in one or two years. Don't be greedy for temporary cheapness. It's very troublesome to repair in the future and shut down the factory. Therefore, the fast door is a product that needs to strictly control the quality. In order to be cheap, many purification engineering companies install low-cost and poor quality fast doors for the owners. Their motors must be quite poor, so they have problems after using them for a year or two. Many enterprises are attracted by their fame and prosper.
2. Control performance: it is controlled by high-tech PLC and frequency converter, and adopts advanced weak current control mode. Strong current is converted to weak current control, and the door is sensitive to prevent leakage.
3. Guide rail design: the guide rail adopts the double row brush sealing structure of PVC brush card base, which can prevent mosquitoes and dust. The bottom of the door curtain is equipped with an inflatable airbag structure, which can closely fit with the ground.
4. Door body and door frame: the door frame is made of 2.0mm cold-rolled steel plate and high-quality imported plastic powder paint baking process.
2、 Xingerwang fast door has a variety of control modes:
1. Geomagnetic control system:
The geomagnetic control system uses the circle surrounded by the rising sun geomagnetic induction line to sense iron substances, such as forklift. When the forklift passes through the geomagnetic field, it can open the fast door and drive out directly, which is very convenient for unloading and loading.
2. Control box system:
Commonly known as the button type, this is the basic configuration of the fast door. As long as there is a button, it can be opened.
3. Radar control system:
As long as there is a moving object where the radar sweeps, it can be turned on. However, the accuracy is not as accurate as geomagnetism, and there is no fixed range that can be adjusted.
4. Interlock control system:
After the interlock controller is installed, two doors and three doors can be interlocked, so that the doors can not be opened at the same time.
5. Airbag control system:
The protective air bag can prevent people and vehicle goods from being injured. The air bag senses obstacles and plays a protective role.
