随着工业技术和密封技术的展开，工业泵在电力、化工、石油等多个行业中得到了大量的运用。工业泵的密封对整个设备运转来说起着重要的作用。那接下来就让工业泵选型的小编来为您引见一下工业泵选型蜜蜂呈现问题应该采取哪些措施吧。
1.填料材料的选择。选择填料时我们主要看能否具备这几个条件:①在压盖压力下有足够的塑性，在压紧力作用下能否产生一定的径向力并与紧密轴接触，填充一切的松孔、缝隙，从而堵塞透露。②有足够的化学稳定性，不污染介质，填料不被介质泡胀，填料中的浸渍剂不被介质溶解，不受密封的液体、气体和润滑液体的腐蚀。
2.加装填料。在加装填料是，必需对填料室清算干净，不允许有任何杂质和污垢。检查填料函和填料尺寸，根据泵轴的尺寸圈切，不易太短。填装时不得用锐器(如改锥、铁丝等)扎压填料，以免使填料构成孔洞影响密封效果，装填压实过程中压盖不可偏斜，构成靠近压盖一段的填料压得太紧，紧固时要均匀用力。
3.泵轴窜量大的处置。合理地设计轴向力的平衡装置，消弭轴向窜量。关于多级离心泵，设计方案是:平衡盘加轴向止推轴承，由平衡盘平衡轴向力，由轴向止推轴承对泵轴中止轴向限位。
4.增加辅助冲洗系统。密封腔中密封介质含有颗粒、杂质，必需中止冲洗，否则会因结晶的析出，颗粒、杂质的堆积，使机械密封的弹簧失灵，假设颗粒进入摩擦副，会招致机械密封的疾速破坏。机械密封的辅助冲洗系统可以有效地维护密封面，起到冷却、润滑、冲走杂物等作用。
With the development of industrial technology and sealing technology, industrial pumps have been widely used in many industries such as electric power, chemical industry, petroleum and so on. The sealing of industrial pump plays an important role in the operation of the whole equipment. Then let the industrial pump selection of small series for you to introduce the industrial pump selection bee problems should take what measures.
1. Selection of packing materials. When choosing packing, we mainly see whether the following conditions can be met: ① there is enough plasticity under the gland pressure, and whether a certain radial force can be generated under the compression force and contact with the tight shaft to fill all the loose holes and gaps, so as to block the leakage. ② it has enough chemical stability, does not pollute the medium, the filler is not expanded by the medium, the impregnant in the filler is not dissolved by the medium, and is not corroded by the sealing liquid, gas and lubricating liquid.
2. Add packing. When adding packing, the packing chamber must be cleaned and free of any impurities and dirt. Check the size of stuffing box and packing, and circle cut according to the size of pump shaft, which is not easy to be too short. During filling, sharp tools (such as screwdriver, wire, etc.) shall not be used to tie and press the packing, so as not to make the packing form a hole and affect the sealing effect. During filling and compaction, the gland shall not be inclined, and the packing near the gland section shall be pressed too tightly, and even force shall be applied during fastening.
3. Disposal of large displacement of pump shaft. The balance device of axial force is designed reasonably to eliminate axial displacement. As for the multi-stage centrifugal pump, the design scheme is: balance plate plus axial thrust bearing, balance the axial force by the balance plate, and stop the axial limit of the pump shaft by the axial thrust bearing.
4. Add auxiliary flushing system. The sealing medium in the sealing cavity contains particles and impurities, so it is necessary to stop flushing. Otherwise, the spring of the mechanical seal will fail due to the precipitation of crystallization and the accumulation of particles and impurities. Assuming that particles enter into the friction pair, it will cause rapid damage to the mechanical seal. The auxiliary flushing system of mechanical seal can effectively maintain the sealing surface and play the role of cooling, lubricating and flushing away sundries.
