但一般試壓泵與管網(wǎng)連接處要安裝一個(gè)閥門或者止回閥,防止管網(wǎng)介質(zhì)回流,并且試壓泵上壓力表的壓力也容易受試壓泵活塞工作而容易產(chǎn)生波動(dòng)。所以一般將管網(wǎng)壓力升至試驗(yàn)壓力后,關(guān)閉試壓泵與被測管網(wǎng)之間的閥門,來觀察被測管網(wǎng)有無滲及管網(wǎng)上壓力表壓力值下降范圍是否符合規(guī)范要求;壓力試驗(yàn)是否合格,要以被測管網(wǎng)上的壓力表讀數(shù)下降范圍為準(zhǔn)。當(dāng)葉輪旋轉(zhuǎn)時(shí),由于葉輪內(nèi)運(yùn)動(dòng)液體的離心力Fu大于在流道內(nèi)運(yùn)動(dòng)液體的離心力只,兩者之間產(chǎn)生一個(gè)旋渦運(yùn)動(dòng),其旋轉(zhuǎn)中線是沿流道縱向,稱為縱向旋渦,在縱向旋渦作用下,液體從吸人至排出的整個(gè)過程中,可以多次進(jìn)人與流出葉輪,類似于液體在多級(jí)離心泵內(nèi)的流動(dòng)狀況。液體每流經(jīng)葉輪一次,就獲得一次能量。當(dāng)液體從葉輪流至流道對(duì),就與流道中運(yùn)動(dòng)的液體相混合。由于兩股液流速度不同,在混合過程中產(chǎn)生動(dòng)量交換。流體由吸人口進(jìn)道和葉輪使流道中液體的能量得以增加。管道旋渦泵主要是依靠這種縱向旋渦傳遞能量。
三、管道泵工作條件:
1、吸入壓力≤1. 0MPa,或泵系統(tǒng)工作壓力≤1.6MPa,即泵吸入口壓力+泵揚(yáng)程≤1.6MPa,泵靜壓試驗(yàn)壓力為2.5MPa,訂貨時(shí)請(qǐng)注明系統(tǒng)工作壓力。泵系統(tǒng)工作壓力大于1.6MPa時(shí)應(yīng)在訂貨時(shí)另行提出,以便在制造時(shí)泵的過流部分和聯(lián)接部分采用鑄鋼材料。
2、環(huán)境溫度<40℃,相對(duì)濕度<95%。
3、所輸送介質(zhì)中固體顆粒體積含量不超過單位體積的0.1%,粒度<0.2mm。
注:如使用介質(zhì)為帶有細(xì)小顆粒,請(qǐng)?jiān)谟嗀洉r(shí)說明,以便廠家采用耐磨式機(jī)械密封。
四、管道泵產(chǎn)品特點(diǎn):
1、管道泵為立式結(jié)構(gòu),進(jìn)出口口徑相同,且位于同一中心線上,可象閥門一樣安裝于管路之中,外形緊湊美觀,占地面積小,建筑投入低,如加上防護(hù)罩則可置于戶外使用。
2、葉輪直接安裝在電機(jī)的加長軸上,軸向尺寸短,結(jié)構(gòu)緊湊,泵與電機(jī)軸承配置合理,能有效地平衡泵運(yùn)轉(zhuǎn)產(chǎn)生的徑向和軸向負(fù)荷,從而保證了泵的運(yùn)行平穩(wěn),振動(dòng)小、噪音低。
