簡析泵頭在使用過程中會遇到的常見問題
大家在使用標準型蠕動泵的時候經常會碰到一些問題，下面我就幫大家簡單的介紹一下一些常見的問題以及遇到時的處理方法。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.泵頭問題Pump head problem蠕動泵各款泵頭壓力上限如何？Set forth in peristaltic pump pump head pressure cap?主要取決于泵管能承受的壓力。一般短時可承受0.2MPa的最大壓力，持續承受壓力低于上面的數值。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.蠕動泵最大抽吸高度如何？Peristaltic pump maximum suction height?最大抽吸高度為8.8米水柱。The biggest suction height is 8.8 meters of water.蠕動泵需要止回閥嗎？Peristaltic pump need to check?不需要。蠕動泵獨特的泵體結構決定了不需要止回閥（單向閥）Don"t need. Peristaltic pump unique pump body structure determines the don"t need to check valve (check valve)蠕動泵可以空轉嗎？Peristaltic pump can be idle?可以。它可泵送氣體、液體以及氣液混合流體。You can. It can be pumping gas, liquid and gas liquid mixed fluid.蠕動泵是自吸泵嗎？Self-priming pump peristaltic pump is?是的。能產生超過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.蠕動泵屬于正位移泵嗎？Peristaltic pump belongs to a positive displacement pump?是的。水的流量與轉子的轉速（一定范圍內）成正比。B: yes. The flow of water and the speed of the rotor (a range) is proportional to the.蠕動泵是非虹吸式的嗎？Peristaltic pump is siphon type?是的。任何時刻總有一根輥子壓過泵管將其鎖閉，因此不會產生任何回流。B: yes. Any time there is always a roll over owing to lock it, so does not produce any backflow.蠕動泵可以泵送漿狀流體或研磨性溶液嗎？Peristaltic pump can pumping slurry fluid or abrasive solution?可以。但可泵送的粘度及粒度上限值與所采用的泵管內徑有關。You can. But can be pumping on the viscosity and particle size of limit related to adoption of pump pipe diameter.蠕動泵為何提供如此多的泵頭類型及泵管尺寸？Why peristaltic pump to provide so many type of pump and pump pipe size?為最大限度的適合各種不同應用的場合For maximum is suitable for different application occasions蠕動泵可反向泵送流體嗎？Peristaltic pump can reverse pumping fluid?可以。泵頭順時針或逆時針旋轉時，所有的規格指標相同。You can. The pump head clockwise or counterclockwise, all of the specifications of the same indicators.蠕動泵的泵頭采用何種材質？其化學特性如何？Peristaltic pump pump head adopt what kind of material? Its chemical properties?蠕動泵的泵頭為外殼PPS（聚苯硫醚），滾輪不銹鋼，耐腐蝕；Peristaltic pump pump head for the shell of PPS (polyphenylene sulfide), roller, stainless steel corrosion resistance;PPS耐熱性高（連續使用溫度達240℃）、機械強度高、耐磨。耐多種化學藥品，對大多酸、酯、酮、醛、酚及脂肪烴、芳香烴、氯代烴等穩定，目前尚未發現可在200℃以下溶解聚苯硫醚的溶劑，對無機酸、堿和鹽類的抵抗性極強。不耐氯代聯苯及氧化性酸、氧化劑、濃硫酸、濃硝酸、王水、過氧化氫及次氯酸鈉等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
