无负压供水设备在试用前,应先关闭供水阀,检查各密封阀情况,不允许有泄露现象,开车后,应运行注意事项机泵转向。当压力表指针到上限的时候,机泵自动停止。打开供水阀,就可正常供水、如需定时供水,可把选择开关扳到手动位置。在无负压供水设备中,当由(you)一(yi)台变(bian)频器控(kong)制(zhi)一(yi)台电(dian)(dian)(dian)动(dong)机时,还需(xu)使变(bian)频器的配用电(dian)(dian)(dian)动(dong)机容(rong)量(liang)(liang)与实际电(dian)(dian)(dian)动(dong)机容(rong)量(liang)(liang)相符就可。当一(yi)台变(bian)频器同时控(kong)制(zhi)两台电(dian)(dian)(dian)动(dong)机时,原则上(shang)变(bian)频器的配用电(dian)(dian)(dian)动(dong)机容(rong)量(liang)(liang)应等于两台电(dian)(dian)(dian)动(dong)机的容(rong)量(liang)(liang)之(zhi)和(he)。
