熔体泵、齿轮泵的安装和使用 Installation and Usage

　　1、熔体泵运输、存放时应轻拿轻放。到货后如三个月内不安装，应重新清洗轴封。起吊ZB-100CC以上系列的熔体泵时，应使用吊环螺钉。

　　2.安装前用测具检查、调整泵座与电机传动轴的同心度应确保熔体泵轴在工作时按订货时标明的方向旋转，否则会引起输入轴断裂、泵体损坏。熔体泵安装的底座要平整，并有足够的强度和刚性。在螺栓均匀紧固的情况下，应保证输入轴能无卡滞地均匀回转。万向联轴器的安装误差应不超过其允许的偏差值，以免引起附加力，缩短轴的寿命。安装中旋紧螺钉时用力要均匀。

　　3.熔体泵在交货前均经过严格的试运转检验，各项指标符号要求，交货后可以直接投入使用。无论那种规格的熔体泵启动使用加载负荷时应低速（5rpm左右）运转一段时间，待各轴承处充分润滑后可加载运转，缓慢的提升工作压力，当整体运行状况较为稳定后，则可逐步将泵及整个系统调整至正常的工艺速度与压力。

　　4.熔体泵在加载前，应先均匀预热，温升不得超过120度每小时。在泵没有达到工作温度前不要启动泵，冷启动是容易引起泵损坏的时候。

　　5.对于采用填料密封形式的熔体泵，应及时调整密封压盖的位置，保证佳的密封状态。对于采用螺旋密封的泵，如果需要使用冷却水辅助密封，应在螺旋密封组件上安装1/8或1/4NPT接头，然后通上水源。对于小排量的泵不要让冷却水影响到泵体的加热。

　　1、You should be careful of transporting and storing melt pump. You should clean the shaft seal when you don’t install it within 3 month of arrival. Use rings screws when you lift melt pump of ZB-100 above series.

　　2、Before installation, test with testing tools, adjust concentricity between pump seat and motor shaft. Ensure the melt pump shaft rotates in ordering indicated direction, otherwise that will cause input shaft rupture and the pump body damage. Mounting base of melt pump should be smooth and has enough intensity and rigidity. Under the holding down bolt with is tightened evenly, make sure the input shafts rotate evenly without clamping stagnation. Deviation of universal coupling installation shouldn’t exceed the allowing deviation in order to avoid causing additional force and shortening the shaft life. You should tighten the screws evenly during the installation.

　　3、The melt pumps have past strict test-turn inspection, each indications meet the requirements, you can put them into use directly. Any kinds of melt pumps should run in low speed （about 5 rpm） when you start the pumps. When each bearing has sufficient lubrication the pump can have load operation and the working pressure can be improved slowly. When there is a steady running of the whole line, you can adjust the pump and the whole system into normal operation speed and pressure.

　　4、 Before loading the pump, there should be a even preheating for the pump. The rising temperature shouldn’t exceed 120℃ （250℉） per hour. Don’t start pump before it reaches the operation temperature, cold start is the most likely time to damage the pump. For melt pump with packing seal form, you should adjust the position of the sealing gland promptly to make sure the best sealing condition.

　　5、For melt pump with packing sealing form , you should adjust the position of  sealing cover to ensure the best sealing state. For melt pump with helical sealing form, if it is necessary to use cooling auxiliary seal, you should install 1/8 or 1/4 NPT joint on the helical sealing component, then connecting water. For the small delivery capacity pump, don’t let the cooling water influence the heating of pump body.
