简析泵头在使用过程中会遇到的常见问题

大家在使用标准型蠕动泵的时候经常会碰到一些问题，下面我就帮大家简单的介绍一下一些常见的问题以及遇到时的处理方法。Everyone in the use of standard peristaltic pump often encounter some problems, let me help you simply introduce some common problems and meet when processing method.泵头问题Pump head problem蠕动泵各款泵头压力上限如何？Set forth in peristaltic pump pump head pressure cap?主要取决于泵管能承受的压力。一般短时可承受0.2MPa的最大压力，持续承受压力低于上面的数值。Mainly depends on owing to withstand the pressure. Generally short-term can bear the biggest pressure of 0.2 MPa, continuing pressure on lower than the above value.蠕动泵最大抽吸高度如何？Peristaltic pump maximum suction height?最大抽吸高度为8.8米水柱。The biggest suction height is 8.8 meters of water.蠕动泵需要止回阀吗？Peristaltic pump need to check?不需要。蠕动泵独特的泵体结构决定了不需要止回阀（单向阀）Don"t need. Peristaltic pump unique pump body structure determines the don"t need to check valve (check valve)蠕动泵可以空转吗？Peristaltic pump can be idle?可以。它可泵送气体、液体以及气液混合流体。You can. It can be pumping gas, liquid and gas liquid mixed fluid.蠕动泵是自吸泵吗？Self-priming pump peristaltic pump is?是的。能产生超过660毫米汞柱的真空，不需要在管路里注水就能工作。B: yes. Can produce more than 660 mm hg vacuum, don"t need to water injection can work in the pipeline.蠕动泵属于正位移泵吗？Peristaltic pump belongs to a positive displacement pump?是的。水的流量与转子的转速（一定范围内）成正比。B: yes. The flow of water and the speed of the rotor (a range) is proportional to the.蠕动泵是非虹吸式的吗？Peristaltic pump is siphon type?是的。任何时刻总有一根辊子压过泵管将其锁闭，因此不会产生任何回流。B: yes. Any time there is always a roll over owing to lock it, so does not produce any backflow.蠕动泵可以泵送浆状流体或研磨性溶液吗？Peristaltic pump can pumping slurry fluid or abrasive solution?可以。但可泵送的粘度及粒度上限值与所采用的泵管内径有关。You can. But can be pumping on the viscosity and particle size of limit related to adoption of pump pipe diameter.蠕动泵为何提供如此多的泵头类型及泵管尺寸？Why peristaltic pump to provide so many type of pump and pump pipe size?为最大限度的适合各种不同应用的场合For maximum is suitable for different application occasions蠕动泵可反向泵送流体吗？Peristaltic pump can reverse pumping fluid?可以。泵头顺时针或逆时针旋转时，所有的规格指标相同。You can. The pump head clockwise or counterclockwise, all of the specifications of the same indicators.蠕动泵的泵头采用何种材质？其化学特性如何？Peristaltic pump pump head adopt what kind of material? Its chemical properties?蠕动泵的泵头为外壳PPS（聚苯硫醚），滚轮不锈钢，耐腐蚀；Peristaltic pump pump head for the shell of PPS (polyphenylene sulfide), roller, stainless steel corrosion resistance;PPS耐热性高（连续使用温度达240℃）、机械强度高、耐磨。耐多种化学药品，对大多酸、酯、酮、醛、酚及脂肪烃、芳香烃、氯代烃等稳定，目前尚未发现可在200℃以下溶解聚苯硫醚的溶剂，对无机酸、碱和盐类的抵抗性极强。不耐氯代联苯及氧化性酸、氧化剂、浓硫酸、浓硝酸、王水、过氧化氢及次氯酸钠等PPS high heat resistance (continuous working temperature of 240 ℃), high mechanical strength, wear resistance. Resistance to a variety of chemicals, for most of the acid, ester, ketone, aldehyde, phenol and fat hydrocarbon, aromatic hydrocarbon, chlorinated hydrocarbons, such as stability, can be found under 200 ℃ dissolve polyphenyl thioether solvent, the inorganic acid, alkali and salt resistance. No chlorinated biphenyls and oxidation resistance acid, oxidant, sulfuric acid, nitric acid and aqua regia, hydrogen peroxide and sodium hypochlorite, etc
