混流泵
水泵的傳動方式
我廠生產的HW型系列混流泵均可用柴油機、電機帶動,其傳動方式視各地區動力情況而定,訂貨時根據原動機的型號(功率、轉速)確定水泵的傳動方式,以確定皮帶輪的大小或聯軸器的規格。
IV. Drive Mode of Pump
Our HW
seriel mixed-flow pump can be driven by diesel engine and motor.The drive mode
can be chosen according to the local motive power situation. When placing an
order for the pump, we should decide the drive mode of the pump according to
the prime motor type(power, rotate speed) in order to confirm the size of
pulley or coupling.

使用與保養:Use And
Maintenance
1、經常檢查軸承溫度,軸承箱內應裝70%的鈣基黃油,不得過多或過少,軸承升溫一般不得比周圍超過35°C,軸承的極限溫度不得超過75°C(用手摸感到燙手),若超過應停車檢查原因予以消除。
Check the bearing temperature
regularly.The bearing box should be put 70% butter,it can not be too much or
too little.The temperature rising of bearing can not be more than 35°C higher
than around temperature and the limiting temperature of bearing is 75°C,if the temperature is higher than 75°C, stop to check the reason and adjust it.
效率下降原因
1、由于水流的沖刷,水泵流道內壁和葉輪過水面變得粗糙不平,水泵內流道的摩阻系數增大,再加上水在泵內的流速很大,水頭損失增加。水力效率降低。
2、由于在泵前投加或水質等原因,使泵殼內嚴重積垢或腐蝕。泵殼內積垢嚴重的可以使泵殼壁厚增加2ram左右,而且水泵內壁形成垢瘤,使泵體容積縮小、抽水量減少、并且流道粗糙,水頭損失增加。客積效率和水力效率都降低。
隔膜泵3、由于水泵加工工藝造成的鑄造缺陷、汽蝕、磨蝕、腐蝕和化學浸蝕等原因造成泵流道內產生空洞或裂縫,水流動時產生旋渦而造成能量損失。水力效率降低
