选型提示 Notes for Pump Selection
1、选择产品时，需要注意泵进口流速(包括进口管线流速)。一般进口流速控制在1 m/s以内，1一1.3 m/s需有条件选择，大于1.3m/s需谨慎选择或不选;
1 .Attentions shall be paid to the flow speed at pump inlet (including the flow in the inlet pipe) during selection. In general, the flowat inlet shall be controlled within 1m/s, the flow of 1}1.3m/s can be selected only when the conditions allowed, and the flow greaterthan 1.3m/s shall be selected conservatively or never.
2、由于电机转速越高，泵进口流速越大，可靠性会有所降低，应综合考虑泵的可靠使用，电机的选择请根据选型步骤中的值选取;
2. Because the flow speed at pump inlet will rise up along with the increase of the motor speed, resulting into the decrease ofreliability, therefore, by taking into consideration of the reliable operation of the pump, the motor shall be selected according to therecommended value provided in the Procedures of Type Selection.
3、若输送介质润滑性较好，且温度≤80℃，使用内置轴承结构的泵;若输送介质润滑性较差，或温度>80℃ ,使用外置轴承结构的泵;3. If the lubricating property of the conveying medium is better and the temperature is less than or equal to 80℃，you arerecommended to select the pump with internal bearing; if the lubricating property of the conveying medium is poor and thetemperature is higher than 80℃，you are recommended to select the pump with external bearing.
4、为了更好的避免杂质进入泵内，建议在泵的进口前配备过滤器，过滤精度为40目(过滤面积为过流通径的15-20倍);
4. To better avoid the impurities from entering the pump, it is suggested to provide a filter with filtering accuracy of 40 mesh (filteringarea is 15 20 times of flow passage diameter) in front of pump inlet.
5、如您使用流量要求精确且不在性能参数表范围内，您可以选用变频电机实现，或者我公司根据您实际要求特殊制作
5. If the flow rate required is precise and out of the scope of the performance parameter table, you can use variable frequency motor,or contact our sales people for customized solution.
