Install the expansion door manufacturer. According to the length of the door hole as shown in the table above, when the door is opened, the width of the internal clearance hole shall not be less than M. the internal clearance of the height of the common door shall be reserved with a width and height. If conditions permit, the total opening length of the door can be extended again, so that the through hole can become a small door for later maintenance and extending the retraction circuit of the door. At present, with the sustainable development of society, more and more electronic devices have greatly improved people´s living standards and greatly facilitated our daily life. Next, we will learn the function of the electric door control device.
The micro meter adopts sound level meter, with stable frequency, code transmission, differential frequency reception, good anti-interference and convenient use. The electric door has three functions: open, close and pause. Therefore, stainless steel pipe must be selected. After the switch is sealed, the layman can´t see whether the stainless steel pipe or the iron pipe is used outside.Haifeng Automatic Door Co., Ltd. according to the characteristics of automatic retractable door products and people´s aesthetic habits, can comfortably see the face without looking up or down. Objects about 1.6m high are easy to integrate into the viewer´s sight range, avoiding visual fatigue. The height of the automatic expansion door shall conform to the mechanical principle. The higher the product height of the automatic expansion door is, the weaker the ability to resist the sun and rain, and the shorter the service life. This is an indisputable fact. As most of the automatic expansion doors are exposed to the outside, they will gradually age, aging and failure rate will increase, because of long-term exposure to sunlight and wind and rain.The higher the automatic expansion door is, the greater the stress field is and the worse the wind resistance is. As the saying goes, "trees attract the wind", only by reducing the height of the automatic expansion door as much as possible the overall center of gravity, so that the door moves down, we can reduce the pressure of the area and improve the stability, so we can effectively resist the typhoon. Reducing the height of the automatic expansion door is equal to increasing the strength of the material.Electric device configuration: stainless steel expansion door motor does not need air cooling, fast heat dissipation, high temperature resistance, with overheating protection device. The expansion door is often open. When the motor temperature is too high, the motor will automatically cut off power and stop running. When the temperature drops to about 90 ℃, it will return to operation. Structural features of stainless steel expansion door: it is made of special process pipes popularized abroad, which are bent, welded and shaped. The door body is not easy to deform and durable. The door body is connected by large and small connecting rods to form an expansion door. Dalian connecting rod type is ancient coin plum blossom type, small connecting rod type is diamond type, beautiful and generous, solid and durable.
