混流泵
HW型蝸殼式混流泵按國(guó)家標(biāo)準(zhǔn) 新系列而設(shè)計(jì)的節(jié)能產(chǎn)品。其性能指標(biāo)均達(dá)到國(guó) 先 水平,省材節(jié)能效果顯著。
HW Spiral Mixed-flow Pump is an efficient pump designed by latest
national standard.The performance indexes have been upto the international
advanced level and the material and energy saving result is remarkable.
4、耗用功率太大
The power
cumption is too large
1、轉(zhuǎn)速太高
2、傳動(dòng)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
常用的農(nóng)用泵
離心泵
離心泵型號(hào)、品種規(guī)格及其變型產(chǎn)品在農(nóng)用泵中是多的。根據(jù)水流入葉輪的方式、葉輪多少、泵身能否自吸以及配套動(dòng)力大小和動(dòng)力品種等,離心泵有單級(jí)單吸離心泵、單級(jí)雙吸離心泵、多級(jí)離心泵、自吸離心泵、電動(dòng)機(jī)泵和柴油機(jī)泵等。
2、軸流泵的一般特點(diǎn)
(1)水在軸流泵的流經(jīng)方向是沿葉輪的軸向吸入、軸向流出,因此稱軸流泵。
(2)揚(yáng)程低(1~13米)、流量大、效益高,適于平原、湖區(qū)、河區(qū)排灌。
(3)起動(dòng)前不需灌 ,操作簡(jiǎn)單。
