| 1.机械方面可靠性高、噪声低、振动小。 1. The machine has high reliability, low noise, small vibration. 2.经济上要综合考虑设备费、运转费、维修费和管理费的总成本最低。 2. To comprehensively consider economic equipment cost, operation cost, the lowest total cost of maintenance and management fees. 3.所选的型号和性能符合装置流量、扬程、压力、温度、汽蚀流量、吸程等工艺参数的要求。 3. The types and properties of the selected device capacity and head, pressure, temperature, cavitation flow, process parameters, such as suction. 4.必须满足介质特性的要求。 4. Must meet the requirements of dielectric properties. 1）对输送易燃、易爆有毒或贵重介质的泵，要求轴封可靠或采用无泄漏泵，如磁力驱动泵、隔膜泵、屏蔽泵。 1) for conveying inflammable, explosive or toxic or precious medium pump, require no leakage of pump shaft sealing is reliable or adopted, such as magnetic drive pump, diaphragm pump, shielding pump. 2）对输送腐蚀性介质的泵，要求对流部件采用耐腐蚀性材料，如：氟塑料材质泵，如果腐蚀性不强，也可酌情选用工程塑料泵。 2) for the pump forhandling corrosive mediums for convection component with corrosion resistance materials, such as: fluoride plastic pump, if you don't strong corrosive, also may choose engineering plastic pump. 3）对输送含固体颗粒介质的泵，要求对流部件采用耐腐耐磨材料，必要时轴封采用清洁液体冲洗。 3) for conveying pump, containing solid granules medium requirements convection components with corrosion resistant materials, shaft seals use clean fluid flush when necessary. |
