旋转式和往复式泵启动

        往复泵中,填料箱内的两端和中间还应放入导向环,以保持其同心运动和受柱塞的重力。
  安装填料环后,扭紧螺栓。为了在每个螺母上获一至的压力,建议用扳手或相关的计量装置紧固螺母注意:此时装置如果处于无泄漏状态,可能引起盘根燃烧。建议慢慢扭紧螺栓直至泄漏量达到允许范围。
  运转前,先在无负荷状态下试运转,观察有无异常情况,然后正式开车,细心观测,有无压的不实或过紧,而造成严重泄露或烧坏填料的现象。泵启动时的关键在于确信其在开始时泄漏。如果一开始将盘根紧固至无泄漏状态,则会灼伤填料导致泄漏。
  在安装填料环之后,扭紧螺栓,并确认料盖与填料箱面正确接合。一旦开始紧固螺栓,要确保各个螺栓均匀受力。
  如果应用一个外部润滑系统,在启动前应确信其能正确运行。
  启动时允许高泄漏率。在这过程期间,盘根安位并开始起作用。
  运转约15-30分钟之后,再次紧固螺栓直至泄漏达到允许范围。推荐泄漏量8-10点/分钟。四氟乙烯 填料应允许更大流量来导出热能以减少热膨胀。
Reciprocating pump, the packing box should be at the two ends and the middle of Central Add-oriented in order to maintain the concentric movement and gravity plunger.
Packing ring is installed, the bolt tightening. In order to be one on each nut to the pressure, it is recommended to use wrenches or nut fastening the measuring device Note: At this point if the device is leak-free state, may cause burning packing. Recommended bolt tightening slowly reached up to allow the scope of leakage.
Operation before the load in the absence of a state of commissioning, to observe any unusual circumstances, and then an official car, careful observation, whether real or not pressure tight, and a serious leak or burn the phenomenon of filler. Pump to start when the key is convinced that the leak in the beginning. If a fastener to start packing leak-free state, it will lead to leakage of filler burns.
After installing the packing ring, twisted tight bolts, and confirmed with the filler material to build the right side junction box. Once fastening bolts, each bolt to ensure that the force evenly.
If the application of an external lubrication system should be convinced to start their run to the right.
Startup to allow a high leakage rate. In the process, the packing-an-bit and came into play.
After running about 15-30 minutes, again until the leak fastening bolt to reach permitted. Recommended leakage 8-10 points / min. Tetrafluoroethylene packing should be allowed to export a greater flow of energy in order to reduce the thermal expansion.
