大口径水泥管产量少的原因是什么?

  大口径水泥管是在一些非常大的工程的时候用的到的一种水泥管类型,然而大口径水泥管并不是非常的多的,那么大口径水泥管产量少的原因是什么?
  Large-diameter cement pipe is a type of cement pipe used in some very large projects, but large-diameter cement pipe is not very much, so what is the reason for the small output of large-diameter cement pipe?
  1、管壁塌落:制作40m以上大口径并调整长术塞顶面与臂芯裸露端管时,因管体较重即使湿管坯两端插入短顶面高度相同.然后慢慢抽出管芯,长术塞木塞,在传送带上转动,管体照样塌落,随着管芯被脱出而进入管内,当管芯全部脱落椭圆形,造成废品,这是主要原因。
  : making 1, wall falling over 40 m long of large diameter and adjust the art at the top of the plug with the arm core bare tube, for pipe ends inserted into the pipe body heavier even wet short end face the same height. Then slowly pull out tube core, long plug stopper, turn on the conveyor belt, the tube body still falling, as the tube core is thrown into the tube, when all off the oval tube core, cause waste, this is the main reason.
  2、接触面较:靠它们之间的摩擦阻力难以完成,长水塞应有钕动感,以防授出管芯如加大托架与湿管坯包角,则无法将缠有湿管坯的管放在超过管外径一半的托传送带上停止转动,否则将无法脱出,造成脱大口径管芯十分困难,影响大出现抱死现象口径管生产。
  2, the contact surface is: by the friction between them is difficult to finish, long water plug should have move feeling, neodymium in case of handing out mandrel pipe Angle, such as enlarging the bracket and wet of the pipe cannot be bound to have a wet pipe in more than half of the conveyor belt to stop rotating, pipe diameter, otherwise will not be able to emerge cause is very difficult to take off the large diameter pipe core, influence of lock phenomenon in a large diameter pipe production.

  3、脱芯困难:各厂一般采用蜕车脱.掉连接器,将带有长术塞的湿管坯送到传送0mm以上口径管芯,即在脱车上放一只比30带上预硬(预硬温度6~7C)~小时管子略长的半圆形托架,脱芯时将缠有湿管抽出长术塞,管壁不会产生椭圆变形,脱Ⅱj坯的管芯放在托架上,然后开动脱车依靠的长术塞应迅速反回再用,术塞数量视不同管坯与托架的摩擦力实现脱芯。
  3, stripping difficult GeChang generally USES the shedding off car. Connector, with long operation of wet pipe to transmit more than 0 mm diameter tube core, namely in advance out of the car to put a more than 30 take hard (hard temperature 6 ~ 7 c) ~ hours longish semicircle pipe bracket, stripping the extract with wet pipe plug, long wall won't produce elliptical deformation, take off the Ⅱ j billet tube core on the bracket, and then start to take off the vehicle, relying on long should be quickly return to use plug, plug number operation depending on different friction to achieve stripping tube billet and the brackets.
  所以在我国大口径水泥管的制造还是比较难的,但是大口径水泥管发挥的作用实在是非常的有价值。
  So in our country the manufacture of large diameter cement pipe is still difficult, but the role of large diameter cement pipe is very valuable.
