出

水

1．進(jìn)水管或油封處漏氣Air

leakage exists in inlet

pipe or in sealing parts．

2．泵體內(nèi)儲(chǔ)水不夠Water

stored in the pump boay is

insufficient．

3．水泵反轉(zhuǎn)Revolution

direction reversed．

4．進(jìn)水管太長(zhǎng)Length of

inlet pipe is too long．

5．吸程過(guò)高Suction lift is

too high．

6．出口閥關(guān)閉無(wú)法排氣

Outlet valve is turned off

unable to discharge air．

1．檢修進(jìn)水管，適當(dāng)壓緊填料或更

換  Repair the inlet pipe，press

sufficiently the sealing filler or

replace it．

2．增加儲(chǔ)水，檢查泵內(nèi)逆止閥是否

密封或堵塞Increase the storage of

water．Examine whether the check

valve in the pump is sealed or

blocked．

3．檢修糾正Check and correct it．

4．縮短進(jìn)水管shortenthe inletpipe．

5．降低吸程Lowerthe suctionlift．

6．打開(kāi)出口閥或泵體上的螺塞Turn

on the outlet valve，or the．screw plug

on the pump body．．

足

1．濾網(wǎng)或葉輪堵塞Filter

gauze valve or vane wheel is

blockcd．

2．密封環(huán)處漏水嚴(yán)重

Serious water leakage in the

sealingring．

3．揚(yáng)程太高The lift is too

high

4．進(jìn)水管漏氣Air leakage

exists in the inlet pipe．

5．吸程過(guò)高，局部產(chǎn)生汽

蝕Suction lift is too high．

Local vapour etching appears．

1．清除堵塞物Clear the blockage．

2．更換密封環(huán)Replace the sealing

ring．

3．降低揚(yáng)程Lower the lift．

4．檢修進(jìn)水管Repair the inlet pipe．

5．降低泵安裝高度，減少進(jìn)口阻力

Lower the installation site of the

pump to decrease the inlet resistance．
