「齐齐哈尔伸缩门」伸缩门延长寿命

 

 

 电动伸缩门的几乎组件是导轨、滑轮及传动皮带。因为这三个部分与电动伸缩门的运行直接有关,是电动伸缩门正常使用条件下的易损件,其布局设计、材料、加工精度、安装和调节精度决定了其维修保养要求和使用寿命。电动伸缩门电气组件的寿命主要与不当使用和偶然事故有关。

 

 

Almost all components of the electric telescopic door are guideways, pulleys and transmission belts. Because these three parts are directly related to the operation of the electric telescopic door, and are vulnerable parts under the normal operation conditions of the electric telescopic door. Its layout design, material, processing accuracy, installation and adjustment accuracy determine its maintenance requirements and service life. The service life of electrical components of electric telescopic doors is mainly related to improper use and accidental accidents.

 

 

 长期以来,电动伸缩门滑轨的设计完全不同于非电动伸缩门滑轨的设计。后者通常有两道水平方向的平行滑轨,两个(或四个)滑轮通过中心的连接件与悬挂的移动门体相连,移动门体的重心恰好在两道滑轨的支撑力之间,形成稳定的"正悬挂",这种稳定的布局可以达到很好的稳定性和静音效果。但是,电动伸缩门的滑轨因为要兼顾与门框的固定、门体吊挂及调节、电气组件的安装和外饰盖板的安装等功能,因此非常简略的主张就是将滑轨设计成单侧滑道,门体在一侧通过滑轮侧向吊挂在滑轨上,形成侧悬挂。这种设计的优点是安装和调节门体便利、维修也容易。但是,这种设计有很多弱点。

 

For a long time, the design of electric telescopic door slideway is completely different from that of non-electric telescopic door slideway. The latter usually has two parallel slides in horizontal direction. Two (or four) pulleys are connected with the suspended moving door body through the central connecting parts. The center of gravity of the moving door body is just between the support forces of the two slides, forming a stable "positive suspension". This stable layout can achieve good stability and silence effect. However, because the slideway of the electric telescopic door has to take into account the functions of fixing the door frame, hanging and adjusting the door body, installing the electrical components and installing the outer decorative cover plate, it is a very simple idea to design the slideway as a one-sided slideway, and the door body is hanging on the slideway side by pulley side to form a side suspension. The advantage of this design is that it is convenient to install and adjust the door body and easy to maintain. However, this design has many weaknesses.

 因此使用这种电动伸缩门必须注意保养和维护滑轮与导轨上部间隙容易使门体滑落,使用的安全性得不到保证。因此选择这种电动伸缩门必须注意电动伸缩门的抗风压强度。这种不稳定的运行使驱动器负载不断变化,对电气组件的使用寿命影响极大。侧悬挂布局,对门体向上的支撑力都在一条线上,门体重心因为安装精度的误差和风力的影响.使门体不仅形成静态侧摆也产生动态侧摆。为此.这种电动伸缩门门体下部的导向块,通常称为"止摆块",就使用一种轴承,轴承直径小于门体下部导槽,使门体在两方向摆动的条件下仍然可以运行。这种侧摆产生的震动在使用效果上表现为噪音,其后果必然导致滑轮和导轨的磨损。

 

 

Therefore, the use of this kind of electric telescopic door must pay attention to the maintenance and maintenance of the upper clearance between pulley and guide rail, which can easily cause the door body to slide, and the safety of use can not be guaranteed. Therefore, when choosing this kind of electric telescopic door, we must pay attention to the wind compression strength of the electric telescopic door. This kind of unstable operation makes the load of the driver constantly change, which has a great impact on the service life of the electrical components. Side suspension layout, the support force to the door body upward are all on one line. The center of the door body not only forms static side swing but also generates dynamic side swing because of the error of installation accuracy and the influence of wind force. For this purpose, the guide block of the lower part of the electric telescopic door body, commonly known as the "anti-swing block", uses a bearing whose diameter is smaller than the guide groove of the lower part of the door body, so that the door body can still operate under the condition of swinging in two directions. The vibration caused by this side pendulum is shown as noise in use effect, and its consequences will inevitably lead to wear and tear of pulleys and guideways.

 


选好门,上创隆.
