Extrusion Asia Edition 1-2019

51 Extrusion Asia Edition 1/2019 齿轮泵安装在挤出机和挤出模头之间，可将熔体压力从 挤出机转移到齿轮泵。除了可以降低挤出机上承受的应力 外，还能提升吞吐量，显著减少工艺变化对熔体压力的影 响。这使得挤出加工商可以按更严格的容差运行，而不必牺 牲产品均匀性。 这款新的在线工具名叫 Gear Pump Payback Analysis， 通过以下网址发布： https://www.nordson.com/en/divisions/polymer-processing- systems/support/calculators。该工具可以根据树脂价格、生 产率、在采用和未采用齿轮泵时的压力变化和资本投资来计 算节省的树脂成本和收回投资所需的时间。这些输入的信息 可以表示为英制或公制以及世界上的多种货币。 负责熔体输送产品的全球产品经理 Christian Schroeder 表示：“在未使用齿轮泵的情况下，即使只是换了一根新螺 杆，压力的变化幅度也将达到 +/- 5%，使得加工商必须使用 更多树脂才能确保成品符合规格。通过将压力变化幅度降低 到 +/- 1%，BlueFlow 齿轮泵有可能做到节省树脂成本，从而 可以在几个月内收回所有投资。” I nstalled between the extruder and the die, a gear pump shifts the job of building melt pressure from the extruder to the gear pump. Besides reducing stress on the extruder and potentially increasing throughput, the gear pump significantly reduces the effect of process variations on melt pressure. This enables ex- trusion processors to run with narrower tolerances without compromising product uniformity. The new online tool, called the Gear Pump Payback Analysis, is posted at https://www.nordson.com/en/divisions/polymer-pro- cessing-systems/support/calculators. The tool calculates resin cost savings and investment payback time on the basis of resin price, output rate, pressure variation with and without the gear pump, and capital investment. These inputs can be made in ei- ther pounds or kilograms and in many of the world’s currencies. “Even with a new screw, pressure variation without the use of a gear pump typically is in the +/- 5% range, making it neces- sary for the processor to use more resin in order to ensure that the finished product meets specification”, said Christian BKG ® BlueFlow™ 齿轮泵 BKG ® BlueFlow™ Gear Pump 新款在线工具可自动计算安装齿轮泵后节省的树 脂成本和投资回报 New Online Tool Automatically Calculates Resin Savings and Investment Payback after Installation of a Gear Pump 诺信公司开发出一款在线工具，可以快速计算 在安装 BKG® BlueFlow™ 齿轮泵后能够实现的树 脂成本节省额，以及收回对齿轮泵的所有投资需 要的月数。该公司将在 2019 年中国国际橡塑展上 正式推出这款工具（ 展位号 2.1F41 ）。 Nordson Corporation has developed an online tool that quickly calculates the resin cost savings achievable with installation of a BKG® Blue- Flow™ gear pump, plus the number of months in which the investment in the pump is paid back in full. The company will introduce the tool at Chinaplas 2019 ( Booth 2.1F41 ).
