Zmd catena of self inhale magnetic force pumps adopt structure of electrical engine direct link form , by centernog prop up , the structure is tightly , teardown and maintenance is convenient , adopt high - powered magnetism stuff nd fe boron to make inside and outside magnet . isolationsheath assembled make of import nonmetallic material , avoid magnetism backset ullage of the run - of - mill pumps have drastically Zmd系列自吸磁力泵采用電機直聯式結構,由中間支架支撐,結構緊湊,拆卸維護方便,采用高性能磁性材料“釹鐵硼”制造內外磁體,隔離套采用進口非金屬材料,徹底消除了一般磁力泵具有的磁渦流損耗,可輸送高濃度,密度大于1 . 84 t m

The noise of the fan is mainly consist of circumrotatory noise and backset noise based on the theoretical analysis 首先基于風機噪聲理論的分析確定了影響風機噪聲源的主要因素是旋轉噪聲和渦流噪聲。

The backset current boiling point of high balance , surmount all kinds of modern automobiles and brake the system is required 主要性能高平衡回流沸點,超越現代各類汽車剎車系統要求

Resisting the balance backset current boiling point , the ones that reduce and brake oil volatilize effectively 搞平衡回流沸點,有效減少剎車油的揮發。
