不銹鋼混流泵廠家詢問(wèn)報(bào)價(jià)【金石泵業(yè)】

混流泵

（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(dòng)間隙以后，保持規(guī)定的軸向間隙）。間隙過(guò)小產(chǎn)生磨擦，過(guò)大則會(huì)導(dǎo)致泵內(nèi)壓力水回流，使泵的效率降低，通過(guò)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.

3、安裝基礎(chǔ)：要求土質(zhì)堅(jiān)實(shí)牢固。

  4、水泵安裝時(shí)，必須保證泵軸的水平位置。

  5、進(jìn)水管末端應(yīng)浸入水平面以下一米左右，但須離開泥底半米左右。

  6、水泵安裝好后，計(jì)算允許吸上高度和揚(yáng)程，在水位穩(wěn)定的條件下，要求為規(guī)定數(shù)量值的0.8~1.2倍范圍，否則水泵不會(huì)正常運(yùn)行

I.

Installation Principle

 1. Installation

Height: Cidering the height according to the rainy season or dry season.The suction

vacuum

height can

not be higher than the adsorbing height.

 2. Installation

Location:The location is better to close to the water source as p  as

can.It should be not

only

keeping the safety but also shortening the water inlet pipe and reduce the

headloss

Failure Casues and Resolving Methods

 故障現(xiàn)象

 Failures

 原     因

 Reas

 消 除

 方 法

 Methods

 1、水泵不出水

 No water are

 runing out

 1、引水不夠真空泵抽吸空氣不盡

 2、進(jìn)水管路進(jìn)氣

 3、水泵轉(zhuǎn)速太低

 4、吸程太高

 5、水泵轉(zhuǎn)向不對(duì)

 6、輸水高度超過(guò)規(guī)定

 1.The diversion is not engouth or the

 vacuum pump does not remove all air

 2.Air suction for inlet pipes

 3.The rotate speed of pump is too low

 4.Suction head is too high

 5.The turnning direction is not right

 6.Water delivery height exceeds stated

 one.

 1、繼續(xù)加灌或抽氣

 2、檢查并堵塞之

 3、用轉(zhuǎn)速表檢查予以調(diào)整

 4、降低安裝位置減少吸程

 5、改變旋轉(zhuǎn)方向

 6、減少輸水高度

 1.Continue filling or removing air

 2.Check and seal it

 3.Check by tachometer and adjust it

 4.Reduce the installation po ition,

 reduce the suction head

 5.Change the turnning direction

 6. Reduce water delivery height

 8、填料處漏水太多

 The padding is

 leaking water too much

 1、填料壓得太松

 2、填料裝置不好

 3、填料大小不一或磨損過(guò)多

 4、填料質(zhì)量差，密封性不好

 5、軸套磨損太多

 1.The padding is pressed too loose

 2.The padding does not assemble well

 3.The padding is not of niform size or it

 wears too much

 4.The padding is with bad quality and

 tightness

 5.

 1、上緊壓蓋到適應(yīng)程度

 2、調(diào)整填料搭口，使之錯(cuò)開一定角度而不在一個(gè)方向

 3、更換填料

 4、更換符合要求的石棉填料

 5、更換軸套

 1.Tighten the gland up to suitable degree

 2.Adjust the padding jiont up to some

 angle not in the same direction.

 3.Change the padding

 4.Change the suitable asbestos padding

 5.Change the axle sleeve.
