液體在壓(ya)差作用下進(jìn)入齧合空間(jiān)容積。當容積(jī)增至最大而(er)形成一個密(mì)封腔時，液體(ti)就在一個個(gè)密封腔内連(lián)續地沿軸向(xiang)移動，直至排(pái)出腔一端。這(zhe)時排出腔一(yi)端的螺杆齧(niè)合空間容積(ji)逐漸縮小，而(ér)将液體排出(chu)。三螺杆泵的(de)工作原理與(yǔ)齒輪泵相似(sì)，隻是在結構(gòu)上用螺杆取(qu)代了齒輪。表(biao)為各種螺杆(gan)泵的特點和(hé)應用範圍。三(sān)螺杆泵的流(liú)量和壓力脈(mo)沖很小，噪聲(shēng)和振動小，有(you)自吸能力，但(dàn)螺杆加工較(jiào)困難。泵有單(dan)吸式和雙吸(xī)式兩種結構(gou),但單螺杆泵(beng)僅有單吸式(shi)。三螺杆泵必(bì)須配帶安全(quán)閥(單螺杆泵(bèng)不必配帶），以(yǐ)防止由于某(mǒu)種原因如排(pái)出管堵塞使(shi)泵的出口壓(ya)力超過容許(xu)值而損壞泵(beng)或原動機。Liquid under the action of pressure difference mesh into space volume.When the volume to maximum and form a sealed chamber, the liquid is in a sealed cavity continuously along the axial movement, until one end discharge chamber.Then screw meshing space at the end of the discharge chamber volume shrinking, and liquid discharge.The working principle of three screw pump and gear pump are similar, just on the structure of screw to replace the gear.Table for all kinds of screw pump characteristics and application scope.Three screw pump flow and pressure pulse is small, little noise and vibration, self-priming ability, but the screw processing more difficult.Pump is single suction and double suction type two kinds of structure, but only single single screw pump suction.Three screw pump must be installed with the valve (single screw pump don't match), in order to prevent due to some reasons such as the outlet pressure of pump outlet pipe plug more than permissible value and damage to the pump or prime mover. 三(sān)螺杆泵泵結(jié)構:三螺杆泵(bèng)是利用螺杆(gan)的回轉來吸(xī)排液體的。中(zhōng)間螺杆為主(zhu)動螺杆，由原(yuán)動機帶動回(huí)轉，兩邊的螺(luó)杆為從動螺(luó)杆，随主動螺(luo)杆作反向旋(xuán)轉。主、從動螺(luó) 杆的螺紋均(jun)為雙頭螺紋(wén)。三螺杆泵是(shi)螺杆式式容(róng)積泵。在三螺(luo)矸泵中，由于(yu)主螺杆與從(cóng)動螺杆上螺(luó)旋槽相互齧(niè)合及它們與(yǔ)襯套三孔内(nèi)表面的配合(he)，得以在泵的(de)進口與出口(kou)之間形成數(shù)級動密封室(shi)，這些動密封(feng)室将不斷把(ba)液體由泵進(jin)口軸向移動(dong)到泵出 口，并(bing)使所輸送液(yè)體逐級升壓(yā)。從而形成一(yi)個連續、平穩(wen)、軸向移動的(de)壓力液體。三(sān)螺杆泵所輸(shū)送液體為不(bu)含固體顆粒(li)，無腐蝕性油(yóu)類及類似油(you)的潤滑性液(yè)體，粘度1.2~100oE(3.0~760cst)，高粘(zhan)度液體亦可(ke)通過加溫降(jiàng)粘後輸送，其(qí)溫度不超過(guò)150oC。Three screw pump pump structure: three screw pump is the use of screw rotary to absorb liquid.The middle screw to active screw, the prime mover, on both sides of the screw is driven screw, with the active screw do reverse rotation.Lord, driven screw thread are double thread.Three screw pump is screw type positive displacement pump.In three screw pump of coal and gangue, the spiral groove on the main screw and driven screw pitch and they cooperate with three hole on the surface of the bushing, formed between in the import and export of the pump number level dynamic seal chamber, the dynamic seal chamber will continue to move liquids from pump axial pump out of the mouth, and make the conveying liquid booster step by step.To form a continuous, smooth, axial movement of liquid pressure.Three screw pump for conveying liquid not containing solid particles, non-corrosive oil and similar oil lubrication and liquid viscosity of 1.2 ~ 100 oe (3.0 ~ 760 CST), is high viscosity liquids through the heating viscosity after delivery, the temperature does not exceed 150 oc.  工作原理: 由(you)于各螺杆的(de)相互齧合以(yǐ)及螺杆與襯(chen)筒内壁的緊(jin)密配合，在泵(bèng)的吸入口和(he)排出口之間(jiān)，就會被分隔(ge)成一個或多(duō)個密封空間(jian)。随着螺杆的(de)轉動和齧合(hé)，這些密封空(kong)間在泵的吸(xi)入端不斷形(xíng)成，将吸入室(shì)中的液體封(feng)入其中，并自(zi)吸入室沿螺(luó)杆軸向連續(xu)地推移至排(pai)出端，将封閉(bi)在 各空間中(zhong)的液體不斷(duan)排出，猶如一(yi)螺母在螺紋(wen)回轉時被不(bú)斷向前推進(jìn)的情形那樣(yàng)，其中螺紋圈(quan)數看做液體(ti)，當螺釘旋轉(zhuǎn)時螺紋在轉(zhuan)動時就相當(dāng)于液體在螺(luo)杆泵裡面的(de)情形，這就是(shì)螺杆泵的基(ji)本工作原理(lǐ)。螺杆與殼體(tǐ)之間的密封(fēng)面是一個空(kōng)間曲面。在這(zhè)個曲面上存(cun)在着諸如ab或(huò)de之類的非密(mì)封區，并且與(yu)螺杆的凹槽(cao)部分形成許(xu)多三角形的(de)缺口abc、def。這些三(san)角形 的缺口(kǒu)構成液體的(de)通道，使主動(dong)螺杆凹槽A與(yu)從動螺杆上(shang)的凹槽B、C相連(lián)通。而凹槽B、C又(you)沿着自己的(de)螺線繞向背(bei)面， 并分别和(he)背面的凹槽(cao)D、E相連通。由于(yú)在槽D、E與槽F(它(ta)屬于另一頭(tóu)螺線)相銜接(jiē)的密封面上(shang)，也存在着類(lèi)似于正面的(de)三角形缺口(kou)a’b’c’，所以D、F、E也将相(xiàng)通。這樣，凹槽(cáo)ABCDEA也就組成一(yī)個“∞” 形的密封(fēng)空間(如采用(yong)單頭螺紋，則(ze)凹槽将順軸(zhou)向盤饒螺杆(gǎn)，将吸排口貫(guàn)通，無法形成(cheng)密封)。不難想(xiang)象，在這樣的(de)螺杆 上，将形(xíng)成許多個獨(du)立的“∞”形密封(feng)空間，每一個(gè)密封空間所(suo)占有的軸向(xiang)長度恰好等(deng)于累杆的導(dǎo)程t。因此，為了(le)使螺杆能吸(xī)、排油口分隔(ge)開來，螺杆的(de)螺紋段的長(zhǎng)度至少要大(da)于一個導程(chéng)。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. 螺杆泵有以(yi)下優點：1)壓力(lì)和流量範圍(wei)寬闊。壓力約(yuē)在3.4-340千克力/cm
