液體在(zài)壓差作用下進(jìn)入齧合空間容積。當容積增至最大而形成一個密封腔時，液體就在一個個密封腔内連續地沿軸向移動(dòng)，直至排出腔一端。這時排出腔一端的螺杆齧合空間容積逐漸(jiàn)縮小，而将液體排出。三螺杆(gǎn)泵的(de)工作原理與齒輪(lún)泵相似，隻是在結構上用螺(luó)杆取代了齒輪。表(biǎo)為各種螺杆泵的特點和應用範圍。三螺杆泵的流量(liàng)和壓力脈沖很(hěn)小，噪聲和振動小，有自吸能力，但螺杆加工較(jiào)困難。泵有單吸式和雙(shuāng)吸式兩種結構,但單螺(luó)杆泵僅有單吸式。三螺杆泵必須配(pèi)帶安全閥(單螺杆泵不必配帶），以防止由于某種原因如排出管堵塞使泵的出口壓力超過容許值而損壞(huài)泵(bèng)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. 三螺杆泵泵結構:三螺杆泵是利用螺杆的回轉來吸排液體的。中間螺杆為主動螺杆，由(yóu)原動機帶動回轉，兩邊的(de)螺杆為從動螺杆，随主動螺杆作反向旋轉。主、從動螺 杆的螺紋均為雙頭螺(luó)紋。三螺杆泵是螺杆式式容積泵。在三螺矸泵中，由于主螺杆與從動螺杆上螺旋(xuán)槽相互齧合及它(tā)們與襯套三(sān)孔内表面的配合，得以在泵的進口與出口之間形成數級動密封室，這些動密封室将不斷(duàn)把液體由泵進口軸(zhóu)向移動到泵出 口，并使所輸送液體(tǐ)逐級升壓。從而形成一個連續、平穩(wěn)、軸向移動(dòng)的壓力液體。三螺杆(gǎn)泵所(suǒ)輸送液體(tǐ)為不含固體顆粒，無腐蝕性油類及類似油的潤滑性液體，粘度1.2~100oE(3.0~760cst)，高粘(zhān)度液(yè)體亦可通過加溫降粘後輸送，其溫度不(bú)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.  工作原理: 由(yóu)于各螺杆的相(xiàng)互齧合以及(jí)螺杆與襯筒内壁的緊密配合，在泵的(de)吸入口和排出口之間(jiān)，就會被分隔成一個或多個密封空間。随着螺杆(gǎn)的轉動和齧合，這些密封空間在泵的吸(xī)入端不斷(duàn)形成，将吸入室中的液體封入其中，并自吸(xī)入室沿螺杆軸向連續地推移至排(pái)出端，将封閉(bì)在 各(gè)空間中的液體不斷排出，猶如一螺(luó)母在螺紋回(huí)轉時被不斷向前推進的情形那(nà)樣，其中螺紋圈(quān)數看做液體，當螺釘(dìng)旋轉時螺紋在轉動時就相當于液體在螺杆泵裡面的情形(xíng)，這就(jiù)是螺杆泵的基本工作原(yuán)理。螺杆(gǎn)與殼體之間的密封面(miàn)是一個(gè)空間曲面。在(zài)這個曲面上存在着諸如ab或de之類的非密封區，并且與螺(luó)杆的凹槽部分形成(chéng)許多三角形的缺口(kǒu)abc、def。這些三角形 的缺口構成液體的通(tōng)道，使主動(dòng)螺杆凹槽(cáo)A與從動螺(luó)杆上(shàng)的(de)凹槽B、C相連通(tōng)。而凹槽B、C又沿着自己的螺線繞向背面， 并分别和背面的(de)凹槽D、E相連通。由于在槽D、E與(yǔ)槽F(它屬于另一頭螺線)相銜接的密封面上，也存在着類似于正面的三角形缺口a’b’c’，所以D、F、E也将(jiāng)相通。這樣，凹槽ABCDEA也就(jiù)組成(chéng)一個“∞” 形的密封空間(如采用單頭螺紋，則凹槽将順軸向盤饒螺杆，将吸(xī)排口貫通，無法形成密封)。不難想象(xiàng)，在這樣的螺杆 上，将(jiāng)形成許多個獨立的(de)“∞”形密封空間，每一個(gè)密封空間所(suǒ)占有的(de)軸向長度恰好等于累杆的導程t。因此，為了使螺杆(gǎn)能吸、排油(yóu)口分隔開來，螺杆(gǎn)的螺紋段的長度至少要大于一個(gè)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. 螺杆泵有以下優點：1)壓(yā)力和流量範圍寬闊。壓力(lì)約在3.4-340千克力/cm 2，流量可達18600cm3/分；2)運送液體的種類和粘度(dù)範圍寬廣；3)因為泵内的回(huí)轉部件慣性力較低(dī)，故可使用(yòng)很高的轉(zhuǎn)速；4)吸入(rù)性(xìng)能好，具有自吸(xī)能力；5)流量均(jun1)勻(yún)連續，振動小，噪音低；6)與其它回轉泵相比，對進入的氣體和污物不太敏感(gǎn)； 7)結構堅(jiān)實，安裝保養容易。rate
