Atlas智能變頻液環泵


而(er)根(gen)據原有問題,我(wo)們設(she)計(ji)了(le)真空解決方案,LRP VSD+智能變(bian)頻液(ye)環泵。

LRP VSD+液環泵對比油旋片真空泵的優勢:

1、適合于真空(kong)度150~700mbar(-30~-85KPa),效率較(jiao)高;

2、無耗材,日常保(bao)養(yang)費用幾乎(hu)為(wei)0;

3、“0級無油認(ren)證“,排放氣體無油,也沒有(you)意外返油進車(che)間(jian)的風險(xian);

4、允許(xu)少量水蒸汽、水滴及固體雜質(zhi)吸入真空(kong)泵;

5、葉輪和端板采用標準(zhun)不銹鋼,并設(she)置可變排氣口(簧板),真空(kong)度更穩(wen)定(ding);

6、LRP VSD+液環泵具(ju)有智能(neng)變頻(pin)控制(zhi),功(gong)(gong)能(neng)強(qiang)大(da)的Mk5電腦控制(zhi)器不(bu)僅可以實現本(ben)機運行監(jian)控、數據(ju)記錄、保養計劃、故(gu)障告警(jing)的功(gong)(gong)能(neng),還有非常強(qiang)大(da)的拓展(zhan)功(gong)(gong)能(neng);


智能變頻液環泵操作界面


此外(wai),LRP為(wei)閉式循環,自(zi)帶自(zi)動排水補水功(gong)能(neng),換水時間可(ke)以根據工藝設(she)置,可(ke)以節約工作液水量達95%。
