如何正确选择球磨铸铁井盖的外形?

来源:http://www.kpp647.com添加时间:2020-06-10 15:36:06

  当时广泛应用的圆形球墨铸铁井盖,之所以规划成圆形不仅是出于安全方面考虑,其比较方形井盖也要更节省铸造材料资源,在足够安全的基础上,还能节省本钱,这样一举两得工作,有什么理由不从之呢?

  At that time, the round nodular cast iron well cover, which was widely used at that time, was planned to be round not only for the sake of safety, but also to save more resources of casting materials compared with the square well cover. On the basis of sufficient safety, it can also save costs. What's the reason why it can't work with one stone?

  通常情况下,在路面上我们常见到的便是圆形的那种。这是因为圆形的井盖与方形比较,稳固性较强,不易出现歪斜不结实的现象,能更好的保障行人和车辆的安全。

  Usually, on the road, we often see the round one. This is because the round well cover is more stable than the square well cover, which is not easy to skew and not solid, and can better protect the safety of pedestrians and vehicles.

  更为深化的原因便是圆形的球墨铸铁井盖通过其圆心的每条直径长度都是一样的,这样一来,当井盖被通过的车辆轧起时,它的直径都会比下面的井口略宽,不会出现井盖掉到井口里的危险。

  The reason for deepening is that the length of each diameter of the round nodular cast iron manhole cover passing through its center is the same, so that when the manhole cover is rolled up by the passing vehicle, its diameter will be slightly wider than the wellhead below, and there will be no danger of the manhole cover falling into the wellhead.

  其实球墨铸铁井盖形状的确认还涉及到一个材料运用率的问题,因为井盖的运用取决于井口的巨细,若是非要装置个面积远远超越井口的方形井盖,那么材料的运用和实用价值显然没有直接运用圆形球墨铸铁井盖来的合适。

  In fact, the confirmation of the shape of the nodular cast iron well cover also involves the problem of the utilization rate of materials, because the utilization of the well cover depends on the size of the wellhead. If the area of the non essential devices is far beyond the square well cover of the wellhead, the application and practical value of the materials are obviously not suitable for the direct use of the round nodular cast iron well cover.

  已然方形球墨铸铁井盖被规划出来,阐明其也有特定的应用规模,那便是乡村和电缆井的运用,方形球墨铸铁井盖可以更好地预防雨水等液体的进入,以免电缆受到水浸。

  The square nodular cast iron well cover has been planned out。 It also has a specific application scale, that is, the use of villages and cable wells。 The square nodular cast iron well cover can better prevent the entry of rainwater and other liquids, so as to prevent the cable from being flooded。

  看了以上的内容,是不是在理论上理解了圆形球墨铸铁井盖为何比方形应用广泛了呢?球墨铸铁井盖作为一个马路上的“常驻军”,确实为我们的日子提供了很大的协助,希望跟着科学技术的开展,其规划上也能更进一步。

  After reading the above content, have you theoretically understood why the round ductile iron manhole cover is more widely used than the square one? As a "resident army" on the road, the ductile iron manhole cover really provides a great help for our day。 I hope that with the development of science and technology, its planning can go further。
