Check the feed throat cooling and focus on extruder zone 1 for resolution.
解决方法是检查喉咙冷却部分和重点检查挤出机器区域1。
But nothing goes through the extruder that doesn't go through the feed throat first.
但是，不先通过喂料口，就没有什么东西通过挤出机。
In an earlier column I discussed feed throat design and how it can affect extruder performance.
在早期的专栏里，我讨论过喂料口(管)设计，以及它是如何影响挤出机的性能的。
Not wanting that to ever happen again, most operators run full coolant flow to the feed throat.
不希望再次出现这种情况，许多操作者就把喂料口的冷却水打满。
Well, it's the feed throat. It's the zone most extruder manufacturers do not treat as a barrel zone.
它就是喂料口，许多挤出机制造商不把它当做机筒区。
As you can see from Fig. 1, the feed throat has a metal-to-metal connection that is very effective at transferring heat.
就象你在图1所见的那样，喂料口有一个金属对金属的连接，它可以有效转移热量。
As I said, everything that goes through the extruder goes through the feed throat first, so this can be a controlling aspect of the process.
如我所说，任何通过挤出机的东西都要先通过喂料口（管），所以这是工艺控制的一个方面。
They are not considering the feed throat as part of the process, but rather as a disconnected apparatus that has nothing to do with the process.
他们没有把喂料口当做工艺的一部分，而是作为一个与工艺无关的孤立部件。
You can solve this problem by adding a modulating valve as a flow control, which can be a controlled by a thermocouple attached to the feed throat.
你可以加一个调节阀作为流体控制的手段来解决这个问题，你在喂料口上加一个热电偶就可以了。
Since the first zone thermocouple is some distance down the barrel from the feed throat, a gradient is developed between the zone 1 setting and the feed throat.
由于一区的热电偶在喂料口下游的某个距离，在一区温度设定和喂料口温度之间就建立了一个温度梯度。
Not only is the feed rate established in the feed throat, but over-cooling the feed throat can extract as much as 20% of the total drive power by pulling heat constantly from zone 1.
不仅是在喂料口建立了喂料速率，使喂料口处于过冷状态还多消耗了总驱动能耗的20%，这是通过在一区恒定吸热实现的。
As a processor, the only way you can maximize feed-throat performance is to adjust its temperature.
作为一个加工者，优化喂料口的唯一方法就是调整它的温度。
For replacing part (s) of needle, presser foot, throat plate, looper, spreader, feed dog, needle guard, folder, cloth guide etc.
更换机针、压脚、针板、弯针、分离器、送布牙、护针器、支架、布导向器等时。
The Michell turbine is very amenable to power control by means of narrowing the feed-nozzle width and for fine control by means of a throttle plate in the throat of the feed-nozzle.
涡轮的米歇尔是非常经得起权力控制缩小饲料喷嘴宽度和良好的控制手段通过在饲料喷嘴喉部油门板的手段。
