混流泵
混流泵,兼有離心泵和軸流泵優(yōu)點(diǎn),結(jié)構(gòu)簡單,區(qū)寬,使用方便,適用于平原圩區(qū)農(nóng)田排灌泵站。中國研制的混流泵中,蝸殼式的揚(yáng)程5~12m,流量900~4000m3/h;導(dǎo)葉式的揚(yáng)程 3~25.7m,流量45~20160m3/h。葉輪直徑5.7m,流量80~100m3/s,揚(yáng)程 6~12m,轉(zhuǎn)速75r/min, 效率92.1%,配套功率7000kW,是世界上投入運(yùn)行的大型混流泵之一。綜上所述,離心泵是由于在葉輪的高速旋轉(zhuǎn)所產(chǎn)生的離心力的作用下,將水提向高處的,故稱離心泵。
混流泵是國際泵行業(yè)的技術(shù)開發(fā)重點(diǎn)之一。它將部分代替離心泵和軸流泵工作。在日本、蘇聯(lián)、澳大利亞等國,混流泵的效率都達(dá)到或超過90%。
2、水泵起動后有一股水就不出水了
After starting ,
the pump only send one stream water then no water runs out
1、吸入的水中有過多氣泡
2、吸水管中窩存空氣
3、吸水管或連接處墊料不嚴(yán)密有進(jìn)氣現(xiàn)象
4、底閥或葉輪有水草雜物填塞
1.There are too many bubbles in the
indrawn water
2.There is air in the suction pipes
3.The paddings in connected parts are
imprecision and produces leaking phenomenon
4.There are waterweeds and sundries
filled in the bottom valve or impeller
1、檢查進(jìn)水管末端是否在水平面以下一米左右
2、排除空氣
3、高速墊料,填塞縫隙擰緊螺栓
4、消除水草雜物
1.Check the end
of water inlet pipe if it is under the water surface at one meter
2. Remove the
air
3.Add padding to
fill the gaps and then tighten the bolts
4.Clear the
waterweeds and sundries.
4、耗用功率太大
The power
cumption is too large
1、轉(zhuǎn)速太高
2、傳動軸彎曲
3、填料壓得太緊
4、軸承磨損或損壞
5、葉輪和前蓋摩擦
6、皮帶太緊
1.The rotate speed is too high
2.The drive shaft is bend
3.The padding is too tight
4.The bearing is worn out
5.Impeller clashes the front cover
6.The belt is too tight
1、降低轉(zhuǎn)速
2、校直
3、擰松壓蓋螺栓或?qū)⑻盍先〕龃虮庖恍?
4、更換軸承
5、調(diào)整葉輪端面軸向間隙
6、適應(yīng)放松
1.Reduce the rotate speed
2.Straightening
3.Loose the cap blot or take our the
padding and make it more flat
4.Change the bearing
5.Ajust the end play of impeller end face
6.Loose the belt to suitable degree
