5、水泵有雜音或振動
There is noise
in pump or the pump is vibrating
1、軸中心沒有對正
2、軸彎曲軸承磨損過大
3、葉輪平衡性差
4、地腳螺栓松動
5、裝置不當(dāng)
6、葉輪局部阻塞
7、吸水高度太高、發(fā)生汽蝕
8、泵內(nèi)掉進(jìn)雜物
1.The axile center is not aligning
2.The axile is bend,五指山市混流泵價格, the bearing wears
much
3.The balance of impeller is not good
4.The foundation bolts are loose
5.The assembly is improper
6.Part of the impeller is blocked
7.The suction head is too high to produce
cavitation
8.There are sundries in pump.
1、找正
2、校正或更換軸承
3、進(jìn)行靜平衡試驗和調(diào)整
4、擰緊
5、檢查機(jī)組
6、消除雜物
7、降低安裝位置減低安裝高度
8、清除雜物
1.Calibrate
2.Calibrate it or change the bearing
3.Do the static balancing test and adjust
it
4.Tighten it
5.Check the pump unit
6.Remove the sundries
7.Reduce the installation site to reduce
the installation height
8. Remove the sundries
(二)泵蓋是泵與進(jìn)水管相連的零件,其端面與葉輪之間留有規(guī)定的軸向端面間隙(在消除軸承軸向活動間隙以后,保持規(guī)定的軸向間隙)。間隙過小產(chǎn)生磨擦,過大則會導(dǎo)致泵內(nèi)壓力水回流,使泵的效率降低,通過增減調(diào)整紙墊達(dá)到規(guī)定的間隙。
II. Pump cover is
the part connected with water inlet pipe.There is an stated axial end face gap
between its end
face and
impeller(Keep the stated axail gap after removing the bearing axial movable
gap).Friction will be
produced if
the gap is too small, contrary, if the gap is too large, the pressure water in
pump will reflux which
makes the
feeiciency reduced.Adjust the paper washer and make the gap be stated one.
4、葉輪表面的氣蝕。由于葉片背水面運(yùn)行時產(chǎn)生負(fù)壓,當(dāng)壓力Pk<Pva時,產(chǎn)生汽穴和蜂窩表面后,球鐵混流泵價格,在電化學(xué)腐蝕作用下,農(nóng)業(yè)混流泵價格,使泵葉汽蝕。
5、容積損失和機(jī)械損失。由于泵使用時間長,機(jī)械磨損產(chǎn)生漏失和阻力增大,雨水混流泵價格,使容積效率和機(jī)械效率降低。
以上原因,使水泵性能變差。運(yùn)行效率降低2~5%,嚴(yán)重的可以使水泵效率降低10%以上。
