力士樂葉片泵傳動帶磨損。有許多大型離水泵采用帶傳,因長期使用,傳動帶磨損而松也,出現(xiàn)打滑現(xiàn)象，降低了水泵轉(zhuǎn)速。 上海維特銳直銷德國REXROTH品牌的產(chǎn)品，并附帶報關(guān)單 REXROTH葉片泵安裝不當。兩帶輪中心距太小或兩軸不太平行，傳動帶緊邊安裝到上面，致使包角太小，兩帶輪直徑計算差錯以及聯(lián)軸傳動水泵兩軸偏心距較大等，均會造成水泵轉(zhuǎn)速變化。 有相當一部分用戶因力士樂原配電動機損壞，就隨意配上另一臺電動機帶動，結(jié)果造成了力士樂葉片泵流量少、水泵轉(zhuǎn)速過低、揚程低抽不上水后果。 REXROTH葉片泵本身機械故障。葉輪與泵軸緊固螺母松脫或泵軸變形彎曲，造成葉輪多移，直接與泵體摩擦，或軸承損壞，都有可能降低水泵轉(zhuǎn)速。 上海維特銳在德國與REXROTH合作，可長期穩(wěn)定供應(yīng)力士樂葉片泵，力士樂電磁閥，REXROTH導(dǎo)軌，力士樂柱塞泵等產(chǎn)品
