工程塑料脱硫泵具有什么特点?-程跃泵业
2019.04.23
1、强大的耐磨性:过流部件全部采用钢衬超高分子量聚乙烯(UHMW-PE)制造,超高分子量聚乙烯(UHMW-PE)的耐磨性居塑料之首,比尼龙66(PA66)、聚四氟乙烯(PTFE)高4倍,是碳钢、不锈钢耐磨性的7-10倍。
     2、强大的耐冲击性:超高分子量聚乙烯的冲击强度位居通用工程塑料之首,是(丙烯腈/丁二烯/苯乙烯)共聚物(ABS)的5倍,且能在零下196℃下坚持稳定,这是其它任何塑料所没有的特性。
     3、优秀的耐腐蚀性:该泵在一定温度和浓度范围内能耐各种腐蚀性介质(酸、碱、盐)及有机溶剂,在20℃和90℃的80种有机溶剂中浸渍30d。表面无任何反常现象,其它物理性能也简直没有变化。
     4、无噪音:超高分子量聚乙烯冲击能吸收性为塑料中高值,消音性好,从而在保送过程中大限度的减小了液体活动产生的噪音。
     5、平安牢靠,无毒素合成:该泵所采用超高分子量聚乙烯(UHMW-PE)化学性能极端稳定,因而亦合适在食操行业运用。
     6、摩擦系数低:该泵的内部的摩擦系为仅为0.07-0.11,故具有自光滑性。在水光滑条件下,其动摩擦系数比PA66和聚甲醛(POM)低一半。当以滑动或转动方式工作时,比钢和黄铜加了光滑油后的光滑性还要好。
     7、抗粘性好:超高分子量聚乙烯(UHMW-PE)抗粘性极好,抗粘附才能与PTFE相当,因而在保送一些黏度较高的介质时亦表现突出。
1. Strong wear resistance: All the overflow parts are made of UHMW-PE with steel lining. UHMW-PE has the highest wear resistance among plastics, 4 times higher than PA66 and PTFE, and 7-10 times higher than carbon steel and stainless steel.

2. Strong impact resistance: The impact strength of UHMWPE ranks first among general engineering plastics, which is five times as high as that of (acrylonitrile/butadiene/styrene) copolymer (ABS) and can maintain stability at minus 196 C. This is a characteristic that no other plastics have.

3. Excellent corrosion resistance: The pump can resist all kinds of corrosive media (acid, alkali, salt) and organic solvents in a certain temperature and concentration range, and impregnate in 80 kinds of organic solvents at 20 ~90 ~C for 30 days. There are no abnormal phenomena on the surface and no changes in other physical properties.

4. Noise-free: UHMWPE has the highest impact energy absorptivity in plastics and good silence, thus minimizing the noise generated by liquid activities in the process of delivery.

5. Safe and reliable, non-toxic synthesis: UHMW-PE used in this pump has extremely stable chemical properties, so it is also suitable for use in food and gymnastics industry.

6. Low friction coefficient: the internal friction system of the pump is only 0.07-0.11, so it has self-smoothness. Under the condition of water smoothness, the dynamic friction coefficient is half lower than that of PA66 and POM. When working in sliding or rotating mode, the smoothness is better than that of steel and brass with smooth oil.

7. Good anti-stickiness: UHMW-PE has excellent anti-stickiness, and its anti-stickiness ability is comparable to that of PTFE, so it is outstanding in delivering some medium with high viscosity.
