力士樂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速。
REXROTH葉片泵電動機因繞組燒毀,而失磁,維修中繞組匝數、線徑、接線方法改變,或維修中故障未*排除因素也會使水泵轉速改變。
REXROTH葉片泵工作前,先將泵內充滿液體,然后啟動離心泵,葉輪快速轉動,葉輪的葉片驅使液體轉動,液體轉動時依靠慣性向葉輪外緣流去,同時葉輪從吸入室吸進液體。上海維特銳供應力士樂葉片泵
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軸傳動水泵兩軸偏心距較大等,均會造成水泵轉速變化。
在這一過程中,力士樂葉片泵的葉輪中的液體繞流葉片,在繞流運動中液體作用一升力于葉片,反過來葉片以一個與此升力大小相等、方向相反的力作用于液體,這個力對液體做功,使液體得到能量而流出葉輪,這時液體 的動能與壓能均增大。
上海維特銳可提供力士樂報關單等證明,在德國設立的分公司,有能力持續(xù)穩(wěn)定供應力士樂產品
