从哪些细节来看开门机的质量?

发布人:http://www.kdjlm.com    发布时间:2019-06-11 10:18:29

  开门机是实现各种门体电动开闭的重要驱动装置。它由电动机、变速机构和离合器装置组成。人们在选择时通常用它来查看其制造工艺是否精细以及工艺质量检验是否严格来确定开门器的质量。然而,这种测定方法只能从其表面而不能从本质上对平开门机的质量进行分析。想知道开门机的质量如何,我们应该从哪些细节来决定呢?

  Door opener is an important driving device for electric door opening and closing. It consists of motor, transmission mechanism and clutch device. It is usually used to check whether the manufacturing process is fine or not and whether the process quality inspection is strict to determine the quality of the door opener. However, this method can only analyze the quality of the door opener from its surface, but not from its essence. To know the quality of the door opener, what details should we decide from?

  1、见电机马力大小。人们通常会问,这扇门有多大?不要认为开门机的尺寸更大更强,这是不科学的。事实上,电机功率取决于转子参数(直径、厚度)和电机磁瓦。铷铁硼材料的磁通量是铁氧体材料的10倍,铷铁硼材料的价格是铁氧体材料的15倍,一些小厂家考虑到成本等因素,只能牺牲铁氧体材料的质量。

  1. See motor horsepower. People often ask, how big is this door? Don't think that the size of the door opener is bigger and stronger. It's not scientific. In fact, the motor power depends on the rotor parameters (diameter, thickness) and the motor magnetic tile. The magnetic flux of rubidium-iron-boron material is 10 times that of ferrite material, and the price of rubidium-iron-boron material is 15 times that of ferrite material. Some small manufacturers can only sacrifice the quality of ferrite material considering cost and other factors.

  2、看电机防水性能。电机防水性能的影响是由电机的出口、底盖密封圈决定的。市场上大部分电机都是室内电机,并没有真正考虑到户外门使用的特殊性。客户只要对门上的电机进行比较,就会发现有些市场上的电机出口为开放式,没有做任何加工,也没有密封,而且密封圈的底盖是绿色的外壳纸,这样的电机肯定没有办法实现防水。

  2. Waterproof performance of motor. The influence of waterproof performance of motor is determined by the outlet of motor and the sealing ring of bottom cover. Most of the motors on the market are indoor motors, and the particularity of outdoor door door use is not really taken into account. As long as the customers compare the motors on the door, they will find that some motors in the market export is open, without any processing, no sealing, and the bottom cover of the sealing ring is green shell paper, such motors certainly can not achieve waterproof.

  3、看电机寿命长短。电机蜗轮蜗杆、轴套、减速器和蜗壳、转子支承结构、安装座等部件选用的材料和制造工艺决定了电机的使用寿命和抗扰流冲击的能力。市场上,一些机电机的出轴套被普通黄铜轴套所取代,转子支承结构也采用单滚动轴承+单铜轴套式支承结构,显然是非常不合理的。

  3. Look at the life of the motor. Material and manufacturing technology of motor worm, sleeve, reducer and volute, rotor support structure, mounting seat and other components determine the service life and anti-disturbance impact ability of motor. In the market, the outlet sleeve of some Motors has been replaced by the ordinary brass sleeve, and the rotor supporting structure also adopts the single rolling bearing + single copper sleeve supporting structure, which is obviously very unreasonable.
