    工作原理(li):

    由于各螺杆(gan)的相互齧合(he)以及螺杆與(yǔ)襯筒内壁的(de)緊密配合，在(zai)泵的吸入口(kou)和排出口之(zhi)間，就會被分(fèn)隔成一個‼️或(huò)多個密封空(kōng)間。随着螺杆(gǎn)的轉動和齧(niè)合，這些密封(fēng)空間在泵的(de)吸入端不斷(duan)形成，将吸入(rù)♉室中的液體(tǐ)封入其中，并(bing)自吸入室沿(yán)螺杆軸向連(lian)續地推移至(zhì)😘排出端，将封(fēng)閉在 各空間(jian)中的液體不(bú)斷排出，猶如(rú)一螺母在螺(luó)紋回轉時被(bèi)不斷向⛹🏻‍♀️前推(tuī)進的情形那(nà)樣，其中螺紋(wén)🔞圈數看做🚶‍♀️液(ye)體，當螺釘旋(xuán)轉✨時螺紋在(zai)轉動時🤟就相(xiang)當于液體在(zai)螺杆泵裡面(miàn)的情形，這就(jiù)是螺杆泵的(de)基本工作原(yuán)理。螺杆與殼(ke)體之間的密(mi)封面是一個(gè)空間曲面。在(zai)這個曲面上(shang)存在着諸如(rú)ab或de之類的非(fei)密封區，并且(qie)與螺杆的凹(ao)槽部分形成(chéng)許✔️多三角形(xing)的缺口abc、def。這些(xie)三角形 的缺(que)口構成液體(tǐ)的通道，使主(zhǔ)動螺杆凹槽(cáo)A與從動螺杆(gan)上的凹槽B、C相(xiàng)連通。而凹槽(cao)B、C又沿着自己(jǐ)的螺線繞向(xiàng)背面， 并分别(bié)和背面的凹(āo)槽D、E相連通。由(you)于在槽D、E與槽(cáo)F(它屬于另一(yi)頭螺線)相銜(xián)接的密封面(miàn)上，也存在着(zhe)類似于正面(miàn)的三角🙇‍♀️形缺(que)口a’b’c’，所以D、F、E也将(jiāng)相通。這樣，凹(āo)槽ABCDEA也就組成(cheng)一個“∞” 形的密(mì)封空間(如采(cai)用單頭螺紋(wen)，則凹槽将順(shùn)軸向盤饒螺(luo)杆，将吸排口(kǒu)貫⭐通，無⛱️法形(xing)成密封)。不難(nán)想象，在這樣(yang)的螺杆 上，将(jiang)形成許多個(gè)獨立的“∞”形密(mì)封空間👈，每一(yī)個密封空間(jiān)所占有的軸(zhóu)向長度恰好(hao)等于累杆的(de)導程t。因此，為(wei)了使螺杆能(néng)吸、排油口分(fen)隔開來，螺杆(gan)的螺紋段☂️的(de)長度至少要(yào)大于一個導(dǎo)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.

    螺杆泵有(yǒu)以下優點：1)壓(yā)力和流量範(fan)圍寬闊。壓力(lì)約在3.4-340千克力(lì)/cm 2，流量可達18600cm3/分(fen)；2)運送液體的(de)種類和粘度(du)範圍寬廣；3)因(yīn)為泵内的回(huí)轉部件慣性(xìng)力較低，故可(kě)使用很高的(de)🈲轉速；4)吸入性(xing)能好，具有自(zì)吸能力；5)流量(liàng)均勻連續，振(zhèn)動小，噪音低(dī)；6)與其它回轉(zhuǎn)泵相比，對進(jìn)入的氣體和(he)污物不太敏(mǐn)✉️感； 7)結構堅實(shi)，安裝保養容(rong)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

    螺杆泵的(de)缺點是，螺杆(gan)的加工和裝(zhuāng)配要求較高(gao)；泵💛的性能👅對(duì)液體的粘度(du)變化比較敏(min)感。Screw pump has the following advantages: 1) the wide range of pressure and flow.Pressure about 3.4-340 kg/cm 2, flow

Suction capacity;5) flow uniformly continuous, little vibration, low noise;6) compared with other rotary pump, less sensitive to enter gas and dirt;7) solid structure, installation and maintenance easy.The screw pump's disadvantage is that the screw processing and assembling the demand is higher;The performance of the pump is more sensitive to the viscosity of the liquid change.

  注意事項:1.三螺(luo)杆泵的轉速(sù)選用:三螺杆泵(beng)的流量與轉(zhuan)速成線性關(guān)系,相對于低轉(zhuan)速的螺杆泵(bèng),高(gāo)轉速的螺杆(gǎn)泵雖然能增(zēng)加了流量和(he)揚程,但功率明(ming)顯增大,高轉速(su)加速了轉子(zi)與定子間的(de)磨耗,必定使螺(luo)杆泵過早失(shī)效,而且高轉速(sù)螺杆泵的定(dìng)轉子長度很(hěn)短,極易磨損,因而(ér)縮短了螺杆(gan)泵的使用壽(shòu)命。通過減速(su)機或無級調(diào)速機構🈲來降(jiàng)低轉速,使勘轉(zhuan)速保持在每(mei)分三百轉以(yi)下較為合理(lǐ)的範♋圍内,與高(gao)速運轉的螺(luo)杆泵相比,使用(yòng)壽命能延長(zhǎng)幾倍。2.螺杆泵的(de)品質:現在市場(chang)上的螺杆泵(bèng)的種類較多(duo),相(xiang)對而言,進口的(de)螺杆泵設計(ji)合理,材質精良(liang),但(dan)價格較高,服務(wù)方面有的不(bú)到位,配件價格(gé)高,訂貨周期長(zhǎng),可(ke)能影響生産(chǎn)的正常運行(hang)。國内生産的(de)大都仿制進(jìn)口産品,産品質(zhì)量良莠不齊(qi),在(zai)選用國内生(sheng)産的産品時(shi),在(zài)考慮其性價(jià)比的時候,選用(yòng)低轉速,長導程(chéng),傳(chuan)動量部件材(cai)質優良,額定壽(shòu)命長的産品(pin)。3.确(que)保雜物不進(jin)入泵體:濕污泥(ni)中混入的固(gu)體雜物會對(dui)螺杆泵的橡(xiang)膠材質定子(zi)造成🌍損壞,所以(yi)确保雜物不(bú)進入泵的腔(qiāng)體是很重要(yào)的,很多污水廠(chǎng)在泵前加裝(zhuang)了粉碎機,也有(yǒu)的安裝格栅(shan)裝置或濾網(wang),阻(zu)擋雜物進入(ru)螺杆泵,對于格(ge)栅應及時清(qīng)撈以免造成(cheng)堵塞。4.保持恒定(ding)的出口壓力(lì):螺(luo)杆泵是一種(zhǒng)容積式回轉(zhuan)泵,當出口端受(shou)阻以後,壓力會(hui)逐漸升高,以至(zhi)于超過預定(dìng)的壓力值.此時(shi)電機負荷急(ji)劇增加.傳動機(ji)械相關零件(jiàn)的負載也會(huì)超出設計值(zhi),嚴(yan)重時會發生(sheng)電機燒毀,傳動(dòng)零件斷裂.為了(le)避免螺杆泵(bèng)損壞,一般會在(zài)三螺杆泵出(chu)口處安裝旁(pang)通溢流閥,用以(yǐ)穩定出口壓(yā)力,保持泵的正(zheng)常運轉。5.避免斷(duan)料:三螺杆泵決(jué)不允許在斷(duàn)料的情形下(xia)運轉,一經發生(shēng),橡(xiàng)膠定子由于(yu)幹磨擦,瞬間産(chan)生高溫而燒(shao)壞,所以,粉碎機完(wan)好,格栅暢通是(shì)螺杆泵正常(cháng)運轉的必要(yào)條件之一,為此(cǐ),有(you)些螺杆泵還(hái)在泵身上安(an)裝了斷料停(ting)機裝置,當發生(sheng)斷料時,由于螺(luo)杆泵其有自(zì)吸功能的特(tè)性,腔體内會産(chǎn)生真空,真空裝(zhuāng)置會使螺杆(gǎn)泵停止運轉(zhuan)。5選(xuan)型問題:三螺杆(gan)泵選型時，要(yào)盡可能詳盡(jin)地了解泵的(de)使用條件，除(chú)了運行參數(shu)，如流量，壓力(li)需要清楚以(yǐ)外，輸送介質(zhi)的特性如介(jie)質的腐蝕性(xing)，含汽量，含固(gù)溶物的比率(lǜ)及固體顆粒(lì)的大小，以☀️及(ji)介質💋的工作(zuò)溫度，粘度，比(bi)重，對材料的(de)腐蝕性等🤟和(he)泵裝置的吸(xī)入條⁉️件，安裝(zhuāng)條件均要了(le)解，
