    工(gōng)作原理:

    由(you)于各螺杆(gan)的相互齧(niè)合以及螺(luó)杆與襯筒(tong)内壁的緊(jǐn)密配合，在(zai)泵的吸入(ru)口和排出(chu)口之間，就(jiu)會被分隔(ge)成一個或(huò)多個密封(feng)空💔間。随着(zhe)螺杆的轉(zhuan)動和齧合(hé)，這些密封(feng)空間在泵(beng)的吸入端(duān)不斷形成(chéng)，将吸入室(shì)中的液體(ti)封入其中(zhōng)，并自吸入(ru)室沿螺杆(gan)軸向連續(xu)地推移至(zhì)排出端，将(jiāng)封閉在 各(ge)空間中的(de)液體不斷(duàn)排出，猶如(rú)一螺母在(zai)螺紋回轉(zhuan)時被不斷(duàn)向前推進(jìn)的情形那(na)樣，其中螺(luo)紋圈數看(kan)做液體，當(dāng)螺釘旋轉(zhuan)時螺紋在(zài)轉動時就(jiù)相當于液(ye)體在螺杆(gan)泵裡面的(de)情形，這就(jiu)是螺杆泵(beng)的基本工(gong)作原理。螺(luo)杆與殼體(ti)之間的密(mì)封面是一(yī)個🔴空間曲(qu)面。在這個(ge)曲面上存(cun)在着諸如(ru)ab或de之類的(de)非密封區(qū)，并且與螺(luó)杆的凹槽(cao)部分形成(chéng)許多三角(jiǎo)形的缺口(kou)abc、def。這些三角(jiao)形 的缺口(kǒu)構成液體(ti)的通道，使(shǐ)主動螺杆(gan)凹槽A與從(cong)動螺杆上(shang)的凹槽B、C相(xiang)連通。而凹(ao)槽B、C又沿着(zhe)自己的螺(luó)線繞向背(bei)面， 并分别(bie)和背面的(de)凹槽D、E相連(lian)通。由于在(zai)槽D、E與槽F(它(tā)屬于另一(yi)頭螺線)相(xiang)銜接的密(mi)封面上，也(ye)存在着類(lei)似于正面(mian)的三角形(xing)缺口a’b’c’，所以(yi)D、F、E也将相通(tong)。這樣，凹槽(cáo)ABCDEA也就組成(chéng)一個“∞” 形的(de)密封空間(jiān)(如采用單(dān)頭螺紋，則(zé)凹槽将順(shùn)軸向盤饒(rao)螺杆，将吸(xī)排口貫通(tong)，無法形成(chéng)密封)。不難(nan)想象，在這(zhè)樣的螺杆(gan) 上，将形成(cheng)許多個獨(du)立的“∞”形㊙️密(mì)封空間，每(měi)一個密封(feng)空間所占(zhan)有的軸向(xiang)長度恰好(hao)🔆等于✊累杆(gǎn)🙇🏻的導程t。因(yīn)此，為了使(shǐ)螺杆能吸(xī)、排油口分(fen)隔開來，螺(luó)杆的螺紋(wén)段的長度(du)至少要大(dà)于一個導(dao)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(beng)有以下優(you)點：1)壓力和(hé)流量範圍(wéi)寬闊。壓力(li)約在3.4-340千克(ke)力/cm 2，流量可(kě)達18600cm3/分；2)運送(sòng)液體的種(zhong)類和粘度(du)範圍寬廣(guǎng)；3)因為泵内(nèi)的回轉部(bù)件慣性力(lì)較低，故可(kě)使用很高(gao)的轉速；4)吸(xī)入性能好(hǎo)，具有自吸(xī)能力；5)流量(liàng)均勻連續(xù)，振動小，噪(zào)音低；6)與其(qi)它回轉泵(bèng)相比，對進(jin)入的氣體(ti)和污物不(bu)太敏🥰感； 7)結(jié)構堅實，安(an)裝保養容(róng)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(shi)，螺杆的加(jia)工和裝配(pèi)要求較高(gao)；泵的性能(néng)對液體的(de)粘度變化(hua)比較敏感(gǎn)。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(shì)項:1.三螺杆(gan)泵的轉速(su)選用:三螺(luo)杆泵的流(liu)量與轉速(sù)成線性關(guan)系,相對于(yú)低轉速的(de)螺杆泵,高(gao)轉速的螺(luó)杆泵雖然(rán)能增加了(le)流量和揚(yang)程,但功率(lǜ)明顯增大(da),高轉速加(jia)速了轉子(zi)與定子間(jian)的磨耗,必(bi)定使螺杆(gan)泵過早失(shi)效,而且高(gao)轉速螺杆(gan)泵的定轉(zhuan)子長度很(hěn)短,極易磨(mo)損,因而縮(suo)短了螺杆(gan)泵的使用(yòng)壽命。通過(guò)減速機或(huo)無級調速(su)機構來降(jiàng)低轉速,使(shi)勘轉速保(bǎo)持在每分(fèn)三百轉以(yǐ)下較為合(he)理的範圍(wei)内,與高速(su)運轉的螺(luó)杆泵相比(bǐ),使用壽命(mìng)能延長幾(ji)倍。2.螺杆泵(beng)的品質:現(xiàn)在市場上(shang)的螺杆泵(bèng)的種類較(jiao)多,相對而(ér)言,進口的(de)螺杆泵設(shè)計合理,材(cái)質精良,但(dan)價格較高(gāo),服務方面(mian)有的不到(dào)位,配件價(jia)格高,訂貨(huo)周期長,可(kě)能影響生(sheng)産的正常(cháng)運行。國内(nei)生産的大(dà)都仿制進(jin)口🔴産品,産(chǎn)品質量良(liáng)莠不齊,在(zài)選用國内(nèi)生産的産(chan)品時,在考(kǎo)慮其性價(jià)比的時候(hou),選用低轉(zhuan)速,長導程(cheng),傳動量部(bu)件材質優(you)良,額定壽(shou)命長的産(chan)品。3.确保雜(za)物不進入(ru)泵體:濕污(wu)泥中混入(rù)的固體雜(zá)物會對螺(luo)杆泵的橡(xiang)膠材質定(ding)子造成損(sǔn)壞,所以确(que)保雜物不(bu)進入泵的(de)腔體是很(hěn)重要的,很(hěn)多污水廠(chang)在泵前加(jiā)裝了粉碎(suì)機,也有的(de)安裝格栅(shān)裝置或濾(lǜ)網,阻擋雜(zá)物進入螺(luo)杆泵,對于(yú)格栅應及(jí)時清撈以(yi)免造成堵(dǔ)塞。4.保持恒(héng)定的出口(kou)壓力:螺杆(gan)泵是一種(zhǒng)容積式回(hui)轉泵,當出(chu)口端受阻(zu)以後,壓力(lì)會逐漸升(sheng)高,以至于(yu)超過預定(dìng)的壓力值(zhí).此時電機(ji)負荷急劇(ju)增加.傳動(dong)機械相關(guan)零件的負(fù)載也會超(chao)出設計值(zhi),嚴重時會(huì)發生電機(jī)燒毀,傳動(dong)零件斷裂(liè).為了避免(miǎn)螺杆泵損(sǔn)壞,一般會(hui)在三螺杆(gan)泵出口處(chu)安裝旁通(tong)溢流閥,用(yong)以穩定出(chu)口壓力,保(bao)持泵的正(zheng)常運轉。5.避(bì)免斷料:三(sān)螺杆泵決(jué)不允許在(zài)斷料的情(qing)形下運轉(zhuǎn),一經發生(sheng),橡膠定子(zi)由于幹磨(mó)擦,瞬間産(chǎn)生高溫而(ér)燒壞,所以(yǐ),粉碎機完(wan)好,格栅暢(chàng)通是螺杆(gan)泵正常運(yun)轉的必要(yao)條件之一(yī),為此,有些(xiē)螺杆泵還(hai)在泵身上(shang)安裝了斷(duàn)料停機裝(zhuāng)置,當發生(sheng)斷料時,由(you)于螺杆泵(bèng)其有自吸(xi)功能的特(tè)性,腔體内(nei)會産生真(zhen)空,真空裝(zhuāng)置會使螺(luo)杆泵停止(zhǐ)運轉。5選型(xíng)問題:三螺(luo)杆泵選型(xíng)時，要盡可(ke)能詳盡地(dì)了解泵的(de)使用條件(jian)，除✍️了運行(háng)參數，如流(liú)量，壓力需(xu)要清楚以(yi)外，輸送介(jie)質的特性(xìng)如介質的(de)腐蝕性，含(han)汽量，含固(gù)溶物的比(bǐ)率及固體(tǐ)顆粒的大(da)小，以及介(jie)質的工作(zuo)溫度，粘度(dù)，比重，對材(cái)料的腐蝕(shi)性等和泵(beng)裝置的吸(xī)入條🥰件，安(ān)裝條件均(jun1)要了解，
