混流泵

（一）   用途：

HW型混流泵為臥式、單級(jí)、單吸、懸臂蝸殼式混流泵，適用于農(nóng)田排灌、工業(yè)、城鎮(zhèn)給排水及船塢、碼頭引水等。

I.                  

Application:

HW Spiral

Mixed-flow pump is a horizontal type, single stage, single suction and

cantilever spiral mixed flow pump, which is used for farmland irrigation and drainage,

industry, town water supply and drainage and water diversion of docks.

（二）開車前準(zhǔn)備：

1、檢查地腳螺栓的堅(jiān)固情況。

2、檢查傳動(dòng)皮帶松緊程度及安裝設(shè)備是否安裝妥善。

3、檢查進(jìn)、出水管是否進(jìn)氣、漏水。

4、檢查填料松緊是否適宜。

5、檢查電動(dòng)機(jī)和水泵軸心線是否在同一直線上，直聯(lián)時(shí)，電動(dòng)機(jī)旋轉(zhuǎn)方向是否符合泵的旋轉(zhuǎn)方向。

6、檢查泵內(nèi)有無障礙，軸是否卡住，用手轉(zhuǎn)動(dòng)應(yīng)輕無雜音。

II. Preparation Before Starting

1. Check the foundation bolts if they are firm.

2. Check the degree of tightness of drive belt and check the

installation if it is suitable.

3.Check the water–in and outpipes if they are leaking water and air.

4.Check the degeree of tightness of padding if it is suitable.

    5.Check the

motor and pump axile lead if they are in the same line and check the direction

of rotation of motor if it is the same with the rotation direction of pump.

    6.Check the

pump if there are barriers , if the axile locks, there should be no noises when

turing it by hand.

 3、水泵出水量不足

 The waer yield

 of water is not enough

 1、進(jìn)水管路或葉輪有水草雜物

 2、轉(zhuǎn)速過低

 3、輸水高度過高

 4、泵蓋及葉輪磨損間隙過大

 5、填料進(jìn)氣

 6、馬力不足

 7、進(jìn)水管口插入水中深度不夠

 1. There are waterweeds and sundries in

 inlet pipes or impeller

 2.The rotate speed is too low

 3.Water delivery height is too high

 4.The attrition gap between pump cover

 and impeller is too large

 5.The padding is air in

 6.The horsepower is not engough

 7.The depth of inlet pipe under water is

 not enough

 1、清除水草雜物

 2、調(diào)整轉(zhuǎn)數(shù)

 3、降低輸水高度

 4、用紙墊調(diào)整間隙至正常

 5、壓緊或更換填料

 6、加大馬力

 7、增加插入水中深度至一米左右

 1.Clear the waterweeds and sundries

 2.Ajust the rotate speed

 3.Reduce the water delivery height

 4.Add paper washers to adjust the gaps

 5.Compact or change padding

 6.Increase the horsepower

 7.Make the depth of inlet pipe under

 water to one meter

不同用途

水泵具有不同的用途，不同的輸送液體介質(zhì)，不同的流量、 不同揚(yáng)程的范圍，因此，它的結(jié)構(gòu)形式當(dāng)然也不一樣，材料也不同，概括起來，大致可以分為：

1 、城市供水 2 、污水系統(tǒng) 3 、土木、建筑系統(tǒng) 4 、農(nóng)業(yè)水利系統(tǒng) 5 、電站系統(tǒng)

6 、化工系統(tǒng) 7 、石油工業(yè)系統(tǒng) 8 、礦山冶金系統(tǒng) 9 、輕工業(yè)系統(tǒng) 10 、船舶系統(tǒng)往復(fù)泵、柱塞泵、活塞泵、隔膜泵、轉(zhuǎn)子泵、螺桿泵、液環(huán)泵、齒輪泵、滑片泵、羅茨泵、滾柱泵、凸輪泵、蠕動(dòng)泵、擾性泵、葉片泵、離心泵、軸流泵、混流泵、漩渦泵、射流泵、噴射泵、水錘泵、真空泵、旋殼泵、軟管泵、蝸桿泵
