　　<流量范围

　　流量:1.63～160m3/min升压:9.8～98kPa

　　<性能表说明

　　流量:性能表中流量Qs是指标准吸气状态（绝对压力101.325kPa、温度20℃、相对湿度50%），介质为空气时罗茨鼓风机的进口流量，对于输送其它介质或非标准状态下的流量段进行换算。

　　流量换算:当进气流量用基准状态（温度0℃，绝对压力101.325kPa）下的流量Qn表示时，需先按下式换算成标准吸气状态下的流量Qs后，再查性能表（通常不考虑湿度）。

　　Qs=1.0733Qn

　　当进气温度ts与20℃相差较大，或者吸入气体分子量M显著地偏离空气分子量29时，实际进气流量Qs按下式计算:

　　Qb=(Qth-Qsa)×[(273+ts)/(273+20)×29/M]1/2

　　Qs=Qth-Qb

　　式中:Qb—吸入气体温度为ts℃，分子量为M时的内泄漏量m3/min；

　　Qth—理论流量m3/min；（根据要求升压下的进口流量，按性能表初步选型后由性能表查得）。

　　Qsa—标准吸入状态下的实际m3/min流量。（初步选型后性能表所示的流量）

　　压力单位换算:9.8kPa=0.1kgf/cm2=1000mmH2O=73.5mmHg=98mbar=0.0967atm

　　表列性能参数以空气为介质，如输送其它介质或进气状态与标准进气状态不符时，流量需进行相应的换算。

　　<性能表使用说明

　　Qs系指在各种进口真空度下，温度为20℃时的进口气体流量。

　　性能表参数以空气为介质，如输送其它介质或进气状态与规定进气状态不符时，实际流量需进行相应的换算。

　　性能表中△符号所示转速表示直联传动，*符号表示可直联也可带联传动，其它均为皮带传动。

　　电动机防护等级如无特别说明，一般选用IP44。

　　<选型订货须知

　　样本性能表参数基于确定的进气状态和排气状态，真空泵选型时，请注明输送介质、进气状态、进口流量、排气压力及环境条件。

　　特殊使用要求如防腐防爆、安装布置、密封、调节、控制方式等等请在订货前说明。
