  杜邦公司(Dupont)使用Radian激光跟踪仪在安装校装50吨级矿石烘干机
  DuPont Co (Dupont) Radian laser tracker used in the installation adjustment of 50 tons ore drying machine

  以下是激光跟踪仪在矿石机械行业应用的典型案例:
  The following is a typical case of laser tracker in ore machinery industry application:
  在位于田纳西州约翰逊维尔的杜邦工厂中,有两台将成吨的重矿加热到4000F(2040C)的50吨级矿石烘干机7*24小运转,因此焦炭和矿石反应区始终非常嘈杂。而且,在该生产阶段,该区域满是灰尘,并且烘干机周围布满了管道、天桥、钢梁和辊子。工厂生产的最终产品是一种广泛用于从牙膏到笔记本纸的白色颜料——钛白粉地(二氧化钛)。
  In Tennessee, Johnson, DuPont plant, two tons of heavy machinery will become heated to 4000F (2040C) 50 tons of ore drying machine 7*24 operation, so the ore and coke reaction zone is always very noisy. Moreover, the area is dusty at the stage of production, and the drier is covered with pipes, bridges, steel beams and rollers. The final product produced by the factory is a white pigment widely used f rom toothpaste to notebook paper - titanium dioxide (titanium dioxide).
  在这样的环境中,杜邦公司的工人和工程师最近更换了陈旧且使用过度的2号烘干机,并使用了API公司的Radian激光跟踪仪来确保新烘干机的完美安装和校准。联系电话186-0138-1355.
  In this environment, the DuPont Co of workers and engineers has recently replaced 2 dryer obsolete and excessive use, and the use of laser tracker Radian API company to ensure the perfect installation and calibration of the new drying machine. Contact the phone 186-0138-1355.
  “烘干机不仅体积巨大,而且笨重,必须用非常特殊的方法进行安装和定位”来自Rotating Machinery Group(旋转机械组)的杜邦设备校准专家Micheal Callan说。新约翰逊维尔工厂在几个星期前更换了1号焦炭和矿石烘干机,更换时使用传统光学器件进行测量,用时超过14个小时。Callan相信:“激光跟踪仪能够提供更加可靠和精确的测量,对2号机的更换非常有帮助。”
  "The dryer is not only huge and bulky, but has to be installed and positioned in a very special way," said Micheal Callan, a DuPont equipment calibration expert f rom Rotating Machinery Group (Rotating Machinery Group). The new Johnson Ville plant changed 1 coke and ore drier a few weeks ago, replacing it with traditional optical devices for more than 14 hours. Callan believes that "laser tracker can provide more reliable and accurate measurement, replacement of the No. 2 machine is very helpful."
  “房子是否坚固取决于地基,烘干机容器也是一样。因此,我们必须使用如Radian激光跟踪仪这样的精确设备,来确保烘干机容器处于正确位置”,Callan说。在更换烘干机时,Callan和其同事旋转机械顾问Mike Burgess必须了解烘干机的位置和倾斜角度。另外,放置辊子的耳轴必须以不同的高度安装,以确保精确的角度。“我们不能出现丝毫差错,”Callan说道。
  "Whether the house is strong or not depends on the foundation, and the same is the same as the dryer container. Therefore, we must use such as Radian laser tracker that precise equipment, to ensure that the dryer vessel is in the correct position, "said Callan. When changing the dryer, Callan and its colleague rotating machinery consultant Mike Burgess must understand the position and angle of the dryer. In addition, the ear axis of the roller must be installed at different heights to ensure an accurate angle. "We can t make a mistake," Callan said.
  “哪怕是三千分之一的英寸的偏移,我们就白忙活了”,Callan补充道。
  "Even if it s a 1/3000 inch offset, we re busy," Callan added.
轻型便携式测量系统(激光跟踪仪)
Portable measurement system (laser tracker)


  Callan从事校准工作已超过16年,在多年的校准工作中,他注意到使用激光跟踪仪将使安装和操作更加快速、简单,因此在2012年,他从API公司购买了一台Radian激光跟踪仪。他指出:“之所选择Radian激光跟踪仪,是因为该型号跟踪仪的便携性——与其他跟踪仪相比,Radian激光跟踪仪是能实现连续测量的最轻便的跟踪仪。”
  Callan is engaged in the calibration work has been more than 16 years, in the calibration work for many years, he noticed that the use of laser tracker will enable more rapid and simple installation and operation, so in 2012, he purchased a laser tracker Radian f rom API. He pointed out: "the selected Radian laser tracker, because this type of portable tracker -- compared with other tracker, Radian laser tracker is able to achieve continuous measurement of the most portable tracker."
  Callan还喜欢API公司提供的支持与维护。自打购买了Radian激光跟踪仪,Callan已经将其用于诸多测量工作中,其中大多数是类似于新约翰逊维尔项目的辊子校准工作。此外,Callan还将该跟踪仪用于佛罗里达州的疏浚项目以及其他设施中绝热板和设备绝缘的测量。
  Callan also likes the support and maintenance provided by API. Since the purchase of the Radian laser tracker, Callan has been applied to many measurement work, most of them are roller calibration work similar to the new Johnson s project. In addition, Callan will also be used to measure the tracker insulated heat insulating plates and equipment in Florida dredging projects and other facilities.
烘干机内外存在巨大压力
There is great pressure inside and outside the dryer


    二氧化钛量一种亮白色颜料,广泛用作食用染料以及纸制品和油漆的基础原料。每年,美国人均二氧化钛用量达10磅,其中超过三分之一的二氧化钛来自田纳西州新约翰逊维尔。二氧化钛的生产过程在距离工厂600英里以外的佛罗里达沼泽便已开始——在这里提取生产二氧化钛的煤焦,然后通过驳船将这些黑色粉末状的焦炭运送到新约约翰逊维尔的杜邦工厂。整个生产过程中,早期工作便是在烘干机中对矿石进行高温高压处理。
    titanium dioxide production, and then transport these black powdered coke to the new DuPont factory in Johnson Ville by barge. In the whole process of production, the early work is to treat the ore at high temperature and high pressure in the dryer.
  为了满足二氧化钛的需求,杜邦不断致力于增加生产时间和提高产量,而其中矿石在烘干机中的高温高压处理就是一道关键工序。另外,减少停机时间也确保实现生产目标的一个主要因素,因此校准工作必须快速进行。
  In order to meet the demand of titanium dioxide, DuPont is committed to increasing production time and increasing output, and the high temperature and high pressure treatment of ore in the dryer is a key process. In addition, the reduction of downtime also ensures a major factor in the realization of the production goal, so the calibration must be carried out quickly.
  要更换新的烘干机,首先要测量旧烘干机,然后使用起重机将旧的烘干机从原来位置上移除。使用Radian激光跟踪仪可以在测量旧烘干机的时候实现跟踪测量,并在适当位置保留一条虚线作为测量的参考点。此外,Callan在跟踪仪周围的四个点安装了可用作参考的测量靶标。在安装新烘干机后,他能够通过观察和测量这些靶标来确定新烘干机的安装位置是否正确。
  To replace the new dryer, first measure the old dryer, and then use the crane to remove the old dryer f rom the original position. Using the Radian laser tracker can achieve tracking measurement when measuring the old drying machine, and at the appropriate position to retain a dotted line as the measurement reference point. In addition, Callan at four points around the installation of the tracker can be used as a reference measurement target. After installing the new dryer, he can determine whether the installation position of the new dryer is correct by observing and measuring these targets.
  接下来,Callan测量新耳轴的正确位置,得到所有四根辊子的三维坐标。
  Next, Callan measures the correct position of the new ear axis and gets the three-dimensional coordinates of all four rollers.
  两对耳轴彼此间距43英尺并且高度略有不同,这样可使烘干机向下倾斜。Callan得出的辊子的距离和角度的测量结果,随后工厂工作人员使用尺量法证明了该测量结果的准确性。
  The two pairs of ear axes are 43 feet apart and slightly different f rom each other, which makes the dryer tilt down. The measurement results of the distance and angle of the roller are obtained by Callan. Then the factory staff use the scale method to prove the accuracy of the measurement results.
挑战
Challenge


  由于支撑结构和管道的妨碍,Callan必须在视线受到阻挡的情况下依靠四个上参考点来确保新烘干机的安装位置和虚线保持一致。此外,该项工作还需要克服其他复杂情况,包括:
  Due to the hindrance of support structure and pipeline, Callan must rely on four reference points to ensure that the installation position of new dryer is consistent with the dashed line when the line of sight is blocked. In addition, the work needs to overcome other complex situations, including:
  附近1烘干机通过钢梁传递的振动,该振动可能会影响测量结果。
  The vibration of a nearby 1 dryer passes through a steel beam, which may affect the measurement results.
  输送热污水的水管带来的温度波动,该温度变化可能导致钢梁轻微变形。
  The temperature fluctuation caused by the pipe conveying hot water may cause a slight deformation of the steel beam.
  参考点的位置可能会过于紧密,甚至可能不在正确位置。
  The location of the reference point may be too close and may not even be in the right position.
  API激光跟踪仪工程师随时提供支持
  API laser tracker engineer to provide support at any time
  每当Callan遇到一个问题,API激光跟踪仪工程师都能给出答案并在工作过程中进行指导。在完成一整天的测量工作后,Callan将测量数据记录在空间分析器中,然后将数据电邮给API公司的服务工程师Will Austin,以确保测量数据的准确性。Austin在查看,能够重新构建Callan的整个测量项目。
  When Callan encounters a problem, API laser tracker engineers can give answers and guidance in the work process. After completing the whole day s measurement work, Callan records the measurement data in the spatial analyzer, then sends the data to API Will Austin, to ensure the accuracy of the measurement data. Austin is looking at the entire measurement project that can be rebuilt for Callan.
  Austin 在家中与Callan进行了一个多小时的通话,他建议Callan在Radian激光跟踪仪周边(包括跟踪仪后面)放置更多的测量靶标,以获得更准确的读数。“你的测量网络向外扩展的越大越好,这榜首可以减小误差”,Austin说。
  Austin at home and Callan for more than an hour call, he suggested that Callan in peripheral Radian laser tracker (including tracker behind) placed the measurement target more, to obtain more accurate readings. "The bigger the scale of your measurement network is, the better, the top can reduce the error," Austin said.
  由于可以和API工程师分享测量结果并讨论整个项目,Callan充满自信,并可确保自己的测量结果是准确的。
  Since you can share the results with API engineers and discuss the whole project, Callan is full of confidence and ensures that the results of their measurements are accurate.
  “仅仅通过查看文件,Austin就能找到这些问题,实在是太不可思议了。他给予了我极大的帮助,”Callan说道。
  "Just by looking at the file, Austin can find these problems. It s really incredible. He gave me a great deal of help, "Callan said.
  尽管测量工作极为复杂,并且精确度要求很高,Callan和Burgess通过测量数据和计算精确地校准了2号烘干机的安装位置。然后,使用起重机将2号烘干机按要求放置在准确位置。完美校准的烘干机不仅可以减少未来所需要的维护工作,还能延长使用寿命。
  Although the measurement is very complex and the accuracy is very high, Callan and Burgess accurately calibrated the installation position of dryer 2 by measuring data and calculation. Then, use the crane to place the No. 2 dryer in the exact position. The perfect calibrated dryer can not only reduce the maintenance work needed in the future, but also prolong the service life.
  无论何地,Radian均可以随身携带激光跟踪仪
  No matter where, Radian can carry a laser tracker
  自烘干机校准工作以后,Callan将API公司的Raddian激光跟踪仪带到欧洲进行了各种各样的测量工作。他计划在接下的工作中,使用激光跟踪仪帮助杜邦工程师在爱荷华移动一个容量达数千加仑的储罐。
  Since the calibration of drying machine, Callan laser tracker Raddian API company to Europe measured various jobs. He plans in the next work, using a laser tracker to help DuPont engineer a mobile tank capacity of thousands of gallons in Iowa.
  激光跟踪仪初次应用于新设施测量时,偶尔会让一些员工吃惊,尤其是那些更加熟悉经纬仪或其他光学方法的老工程师和工作。但Callan相信,  Radian跟踪仪的表现会赢得他们的信任,就像在新约翰逊维尔一样。
Laser tracker is first applied to the new facilities when measuring, occasionally let some employees surprised, especially those old engineers and more familiar with theodolite or other optical methods. But Callan believes that the Radian tracker will win their trust, as well as in the new Johnson.
  “Radian跟踪仪最终以其出色的表现征服了怀疑者,”他说。
  "The final Radian tracker for its outstanding performance to conquer the skeptics," he said.
