液體在壓(yā)差作用下(xià)進入齧合(hé)空間容積(ji)。當容積增(zeng)至最大而(er)形成一個(ge)密封腔時(shí)，液體就在(zài)一個個密(mi)封腔内連(lian)續地沿軸(zhou)向移動，直(zhi)至排出腔(qiang)一端。這時(shi)排出腔一(yī)端的螺杆(gan)齧合空間(jiān)容積逐漸(jiàn)縮小，而将(jiāng)液體排出(chū)。三螺杆泵(beng)的工作原(yuan)理與齒輪(lun)泵相似，隻(zhī)是在結構(gòu)上用螺杆(gǎn)取代了齒(chǐ)輪。表為各(gè)種螺杆泵(bèng)的特點和(hé)應用範圍(wéi)。三螺杆泵(bèng)的流量和(hé)壓力脈沖(chong)很小，噪聲(shēng)和振動小(xiǎo)，有自吸能(neng)力，但螺杆(gan)加工較困(kùn)難。泵有單(dan)吸式和雙(shuāng)吸式兩種(zhong)結構,但單(dān)螺杆泵僅(jin)有單吸式(shì)。三螺杆泵(beng)必須配帶(dài)安全閥(單(dān)螺杆泵不(bu)必配帶），以(yǐ)防止由于(yú)某種原因(yin)如排出管(guǎn)堵塞使泵(bèng)的出口壓(ya)力超過容(rong)許值而損(sǔn)壞泵或原(yuán)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. 三螺(luó)杆泵泵結(jié)構:三螺杆(gǎn)泵是利用(yòng)螺杆的回(huí)轉來吸排(pái)液體的。中(zhōng)間螺杆為(wei)主動螺杆(gan)，由原動機(jī)帶動回轉(zhuan)，兩邊的螺(luó)杆為從動(dong)螺杆，随主(zhu)動螺杆作(zuò)反向旋轉(zhuan)。主、從動螺(luó) 杆的螺紋(wen)均為雙頭(tóu)螺紋。三螺(luo)杆泵是螺(luó)杆式式容(róng)積泵。在三(sān)螺矸泵中(zhōng)，由于主螺(luo)杆與從動(dòng)螺杆上螺(luo)旋槽相互(hù)齧合及它(tā)們與襯套(tao)三孔内表(biao)面的配合(hé)，得以在泵(bèng)的進口與(yǔ)出口之間(jiān)形成數級(ji)動密封室(shi)，這些動密(mì)封室将不(bu)斷把液體(tǐ)由泵進口(kǒu)軸向移動(dong)到泵出 口(kou)，并使所輸(shu)送液體逐(zhu)級升壓。從(cong)而形成一(yi)個連續、平(ping)穩、軸向移(yi)動的壓力(li)液體。三螺(luó)杆泵所輸(shū)送液體為(wei)不含固體(ti)顆粒，無腐(fǔ)蝕性油類(lèi)及類似油(yóu)的潤滑性(xing)液體，粘度(dù)1.2~100oE(3.0~760cst)，高粘度液(ye)體亦可通(tōng)過加溫降(jiang)粘後輸送(sòng)，其溫度不(bu)超過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(zuo)原理: 由于(yu)各螺杆的(de)相互齧合(he)以及螺杆(gǎn)與襯筒内(nèi)壁的緊密(mì)配合，在泵(bèng)的吸入口(kou)和排出口(kǒu)之間，就會(hui)被分隔成(cheng)一個或多(duō)個密封空(kōng)間。随着螺(luo)杆的轉動(dong)和齧合，這(zhe)些密封空(kōng)間在泵的(de)吸入端不(bú)斷形成，将(jiāng)吸入室中(zhong)的液體封(fēng)入其中，并(bing)自吸入室(shi)沿螺杆軸(zhou)向連續地(di)推移至排(pái)出端，将封(fēng)閉在 各空(kong)間中的液(ye)體不斷排(pái)出，猶如一(yi)螺母在螺(luo)紋回轉時(shi)被不斷向(xiàng)前推進的(de)情形那樣(yang)，其中螺紋(wén)圈數看做(zuò)液體，當螺(luo)釘旋轉時(shi)螺紋在轉(zhuǎn)動時就相(xiàng)當于液體(tǐ)在螺杆泵(bèng)裡面的情(qíng)形，這就是(shì)螺杆泵的(de)基本工作(zuò)原理。螺杆(gan)與殼體之(zhī)間的密封(feng)面是一個(gè)空間曲面(mian)。在這個曲(qu)面上存在(zai)着諸如ab或(huo)de之類的非(fei)密封區，并(bing)且與螺杆(gan)的凹槽部(bu)分形成許(xǔ)多三角形(xíng)的缺口abc、def。這(zhè)些三角形(xing) 的缺口構(gòu)成液體的(de)通道，使主(zhǔ)動螺杆凹(ao)槽A與從動(dòng)螺杆上的(de)凹槽B、C相連(lian)通。而凹槽(cáo)B、C又沿着自(zì)己的螺線(xiàn)繞向背面(mian)， 并分别和(he)背面的凹(ao)槽D、E相連通(tōng)。由于在槽(cáo)D、E與槽F(它屬(shu)于另一頭(tou)螺線)相銜(xián)接的密封(fēng)面上，也存(cún)在着類似(sì)于正面的(de)三角形缺(que)口a’b’c’，所以D、F、E也(yě)将相通。這(zhe)樣，凹槽ABCDEA也(yě)就組成一(yi)個“∞” 形的密(mì)封空間(如(rú)采用單頭(tou)螺紋，則凹(ao)槽将順軸(zhóu)向盤饒螺(luo)杆，将吸排(pai)口貫通，無(wú)法形成密(mi)封)。不難想(xiang)象，在這樣(yang)的螺杆 上(shàng)，将形成許(xǔ)多個獨立(lì)的“∞”形密封(fēng)空間，每一(yī)個密封空(kong)間所占有(yǒu)的軸向長(zhǎng)度恰好等(deng)于累杆的(de)導程t。因此(ci)，為了使螺(luo)杆能吸、排(pái)油口分隔(gé)開來，螺杆(gǎn)的螺紋段(duan)的長度至(zhi)少要大于(yu)一個導程(cheng)。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(you)以下優點(diǎn)：1)壓力和流(liu)量範圍寬(kuan)闊。壓力約(yuē)在3.4-340千克力(li)/cm
