    工(gong)作原理:

    由于各(gè)螺杆的相互齧(nie)合以及螺杆與(yu)襯筒内壁的緊(jin)密⭕配合，在泵的(de)吸入口和排出(chu)口之間，就會被(bei)分⁉️隔成一個或(huò)多🤟個密🐅封空🐇間(jian)。随着螺杆的轉(zhuan)動和齧合，這些(xiē)密封空間在泵(beng)的吸入端不斷(duàn)形成，将吸入室(shi)中的液🔞體封入(ru)其中，并自吸♻️入(rù)室沿螺杆軸向(xiàng)連續地推移至(zhi)排出端，将封閉(bì)在 各空間中的(de)液體不🌈斷排出(chū)，猶如一螺母在(zai)螺紋回轉時被(bei)不斷向前推進(jin)的情形那樣，其(qí)🎯中螺紋圈數看(kan)做液體，當螺釘(dìng)旋轉時螺紋在(zai)轉動時就相當(dāng)于液體在螺杆(gan)泵裡面的情形(xing)，這就是螺杆泵(bèng)的基本♻️工作原(yuan)理。螺杆與殼體(ti)之間的密封面(mian)是一個空間曲(qu)面。在這個曲面(mian)上存在着諸如(rú)ab或de之類的非密(mi)封區，并且與螺(luó)杆的凹槽部分(fen)形成許多三角(jiao)形的缺口abc、def。這些(xie)三角形 的缺口(kou)構成液體的通(tong)道，使主動螺杆(gǎn)凹槽A與從動螺(luo)杆上的凹槽B、C相(xiang)連通。而凹槽B、C又(yòu)沿着自己的螺(luo)線繞向背面， 并(bing)分别和背面的(de)凹槽D、E相連通。由(you)于在槽D、E與槽F(它(tā)屬于另一頭螺(luó)線)相銜接的密(mì)封面上，也存在(zai)着類似于正面(mian)的三角📐形缺口(kǒu)a’b’c’，所以D、F、E也将相通(tōng)。這樣，凹槽ABCDEA也就(jiu)組成一個“∞” 形的(de)密封空間(如采(cai)用單頭螺紋，則(ze)凹槽将順軸向(xiang)盤饒螺杆，将吸(xī)排口貫👅通，無法(fǎ)形成密封)。不難(nán)想象，在這樣的(de)螺杆 上，将形成(chéng)許多個獨立的(de)🥰“∞”形密封空間，每(měi)一個密封空間(jiān)所占有的軸向(xiàng)長度恰好等于(yú)累杆🏃‍♀️的導程t。因(yin)此，為了使螺杆(gan)能吸、排油口分(fen)隔開來，螺杆的(de)螺紋段🏃🏻的長度(dù)至少要大于一(yi)個導程。Due to the mutual engagement of each screw and screw and the close coordination of the liner wall, between the inlet and outlet of the pump, can be divided into one or more of the sealed space.With the rotation of the screw and the meshing, the sealed space in pump suction side form unceasingly, the liquid from the suction chamber seal in among them, and the suction chamber along the screw axial continuously goes on to the discharge end, will be closed in the space of the liquid discharge, like a nut in screw rotation being constantly move forward, the screw thread turns as liquid, when screw rotating screw rotation is equivalent to the liquid in the inside of the screw pump, this is the basic work principle of screw pump.The sealing surface between screw and shell is a space curved surface.Exist on the surface of the sealing section, such as ab or DE and screw groove part of the form many the gap of the triangle ABC, def.These triangular gap formation fluid channels, make active screw groove with A driven screw groove on the connected to B and C.And groove B, C and along their spiral around to the back, and, respectively, and on the back of the groove connected to D and E.Due to the tank D, E and F (it belongs to another head spiral) of corresponding seal surface, there are also similar to the positive triangle gap a 'b' c ', so D, F, E will also is same.So, grooves ABCDEA on forming a "up" form of the sealed space (such as using single thread, axial disc groove will arrange spare screw, connecting the suction PaiKou, unable to form a seal).It is not hard to imagine that in this kind of screw, will form a number of independent "up" form sealed space, each of the sealed space occupied the axial length equals the tired stem lead t.Therefore, in order to make the screw suction and discharge of oil can be separated, the length of the screw thread of at least than a lead.

    螺杆泵(bèng)有以下優點：1)壓(ya)力和流量範圍(wéi)寬闊。壓力約在(zai)3.4-340千克力/cm 2，流量可(ke)達18600cm3/分；2)運送液體(ti)的種類和粘度(dù)範圍寬廣；3)因為(wei)泵内的回轉部(bu)件慣性力較低(dī)，故可使用很高(gao)的轉💛速；4)吸入性(xing)能好，具有自吸(xi)能力；5)流量均勻(yún)連續，振動小，噪(zao)音低；6)與其它回(huí)轉泵相比，對進(jìn)入的氣體和污(wū)物不太敏感； 7)結(jie)構堅實，安裝保(bao)養容易。rate of up to 18600 cubic cm/min;2) wide range of delivery and type of liquid viscosity;3) because the rotary inertia force component inside the pump is low, so it can be used in high speed;4) inhalation can good, have since

    螺杆泵(beng)的缺點是，螺杆(gǎn)的加工和裝配(pèi)要求較高；泵❓的(de)性💯能☁️對液🈚體的(de)粘度變化比較(jiao)敏感。Screw pump has the following advantages: 1) the wide range of pressure and flow.Pressure about 3.4-340 kg/cm 2, flow

  注意事(shi)項:1.三(sān)螺杆泵的轉速(su)選用:三螺杆泵的流(liu)量與轉速成線(xian)性關系,相對于低轉(zhuan)速的螺杆泵,高轉速(su)的螺杆泵雖然(rán)能增加了流量(liàng)和揚程,但功率明顯(xiǎn)增大,高轉速加速了(le)轉子與定子間(jiān)的磨耗,必定使螺杆(gǎn)泵過早失效,而且高(gāo)轉速螺杆泵的(de)定轉子長度很(hen)短,極(ji)易磨損,因而縮短了(le)螺杆泵的使用(yong)壽命。通過減速(sù)機或無級調速(sù)機構來降低轉(zhuǎn)速,使(shi)勘轉速保持在(zai)每分三百轉以(yǐ)下較為合理的(de)範☂️圍内,與高速運轉(zhuǎn)的螺杆泵相比(bi),使用(yong)壽命能延長幾(jǐ)倍。2.螺(luo)杆泵的品質:現在市(shi)場上的螺杆泵(beng)的種類較多,相對而(er)言,進(jìn)口的螺杆泵設(she)計合理,材質精良,但價格(gé)較高,服務方面有的(de)不到位,配件價格高(gao),訂貨(huo)周期長,可能影響生(shēng)産的正常運行(háng)。國内生産的大(dà)都仿制進口産(chan)品,産(chǎn)品質量良莠不(bu)齊,在(zài)選用國内生産(chan)的産品時,在考慮其(qí)性價比的時候(hòu),選用(yong)低轉速,長導程,傳動量部(bù)件材質優良,額定壽(shòu)命長的産品。3.确保雜(zá)物不進入泵體(tǐ):濕污(wū)泥中混入的固(gu)體雜物會對螺(luo)杆泵的橡膠材(cái)質定子造成損(sun)壞,所(suo)以确保雜物不(bú)進入泵的腔體(ti)是很重要的,很多污(wu)水廠在泵前加(jia)裝了粉碎機,也有的(de)安裝格栅裝置(zhì)或濾網,阻擋雜物進(jin)入螺杆泵,對于格栅(shān)應及時清撈以(yi)免造成堵塞。4.保持恒(heng)定的出口壓力(lì):螺杆(gan)泵是一種容積(jī)式回轉泵,當出口端(duān)受阻以後,壓力會逐(zhu)漸升高,以至于超過(guo)預定的壓力值(zhí).此時(shi)電機負荷急劇(ju)增加.傳動機械相關(guān)零件的負載也(yě)會超出設計值(zhí),嚴重(zhòng)時會發生電機(jī)燒毀,傳動零件斷裂(liè).為了(le)避免螺杆泵損(sǔn)壞,一(yi)般會在三螺杆(gan)泵出口處安裝(zhuang)旁通溢流閥,用以穩(wěn)定出口壓力,保持泵(beng)的正常運轉。5.避免斷(duan)料:三(sān)螺杆泵決不允(yun)許在斷料的情(qing)形下運轉,一經發生(shēng),橡膠(jiao)定子由于幹磨(mo)擦,瞬(shun)間産生高溫而(ér)燒壞,所以,粉碎機完好,格栅暢(chàng)通是螺杆泵正(zhèng)常運轉的必要(yao)條件之一,為此,有些螺杆(gan)泵還在泵身上(shang)安裝了斷料停(tíng)機裝置,當發生斷料(liào)時,由(you)于螺杆泵其有(yǒu)自吸功能的特(te)性,腔(qiāng)體内會産生真(zhen)空,真(zhen)空裝置會使螺(luo)杆泵停止運轉(zhuǎn)。5選型(xing)問題:三螺杆泵選型(xing)時，要盡可能詳(xiáng)盡地了解泵的(de)使用條件，除了(le)❄️運行參數，如流(liu)量，壓力需要清(qing)楚以外，輸送介(jie)質的特性如介(jiè)質的腐蝕性，含(han)汽量，含固溶物(wù)的比率及固體(tǐ)顆粒的大小，以(yǐ)及介質的工作(zuo)溫度，粘度，比重(zhong)，對材料的腐蝕(shí)性等和泵裝置(zhi)的吸入條件，安(ān)裝條件均要了(le)解，
