水(shui)泵(beng)的(de)同(tong)(tong)心(xin)度即以電機軸(zhou)為主動(dong)軸(zhou)與水(shui)泵(beng)泵(beng)軸(zhou)同(tong)(tong)軸(zhou)心(xin)的(de)程(cheng)度稱(cheng)同(tong)(tong)心(xin)度。

當水(shui)(shui)泵(beng)與電機軸同(tong)(tong)(tong)心(xin)(xin)度偏(pian)差過大(da)時，會(hui)對水(shui)(shui)泵(beng)產(chan)生(sheng)危害。長(chang)期運轉的水(shui)(shui)泵(beng)與電機軸不同(tong)(tong)(tong)心(xin)(xin)，其軸承（或軸瓦）會(hui)嚴重磨損造成設備損壞(huai)；水(shui)(shui)泵(beng)與電機軸不同(tong)(tong)(tong)心(xin)(xin)還會(hui)使水(shui)(shui)泵(beng)在運轉時產(chan)生(sheng)噪聲(sheng)和(he)振(zhen)動，縮短水(shui)(shui)泵(beng)壽(shou)命，并影響水(shui)(shui)泵(beng)效率。

因(yin)此，水(shui)泵的同心(xin)度在安裝時應認真細致的測試調整。
