液體在壓差(chà)作用下進入齧合(he)空間容積。當容積(jī)增至最大而形成(cheng)一個密封腔時，液(ye)體就在一個個密(mì)封腔内連續地沿(yan)軸向移動，直至排(pai)出腔一端。這時排(pai)出腔一端的螺杆(gan)齧合空間容積逐(zhu)漸縮小，而将液體(ti)排出。三螺杆泵的(de)工作原理與齒輪(lun)泵相似，隻是在結(jie)構上用螺杆取代(dai)了齒輪。表為各種(zhong)螺杆泵的特點和(he)應用範圍。三螺杆(gǎn)泵的流量和壓力(lì)脈沖很小，噪聲和(he)振動小，有自吸能(néng)力，但螺杆加工較(jiao)困難。泵有單吸式(shi)和雙吸式兩種結(jié)構,但單螺杆泵僅(jin)有單吸式。三螺杆(gan)泵必須配帶安全(quan)閥(單螺杆泵不必(bi)配帶），以防止由于(yu)某種原因如排出(chū)管堵塞使泵的出(chū)口壓力超過容許(xu)值而損壞泵或原(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. 三螺杆泵泵(beng)結構:三螺杆泵是(shi)利用螺杆的回轉(zhuan)來吸排液體的。中(zhōng)間螺杆為主動螺(luó)杆，由原動機帶動(dong)回轉，兩邊的螺杆(gǎn)為從動螺杆，随主(zhu)動螺杆作反向旋(xuan)轉。主、從動螺 杆的(de)螺紋均為雙頭螺(luó)紋。三螺杆泵是螺(luo)杆式式容積泵。在(zài)三螺矸泵中，由于(yu)主螺杆與從動螺(luó)杆上螺旋槽相互(hu)齧合及它們與襯(chen)套三孔内表面的(de)配合，得以在泵的(de)進口與出口之間(jian)形成數級動密封(feng)室，這些動密封室(shì)将不斷把液體由(you)泵進口軸向移動(dong)到泵出 口，并使所(suo)輸送液體逐級升(shēng)壓。從而形成一個(gè)連續、平穩、軸向移(yi)動的壓力液體。三(san)螺杆泵所輸送液(yè)體為不含固體顆(kē)粒，無腐蝕性油類(lei)及類似油的潤滑(hua)性液體，粘度1.2~100oE(3.0~760cst)，高粘(zhān)度液體亦可通過(guò)加溫降粘後輸送(song)，其溫度不超過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(gong)作原理: 由于各螺(luó)杆的相互齧合以(yǐ)及螺杆與襯筒内(nèi)壁的緊密配合，在(zai)泵的吸入口和排(pái)出口之間，就會被(bei)分隔成一個或多(duo)個密封空間。随着(zhe)螺杆的轉動和齧(niè)合，這些密封空間(jian)在泵的吸入端不(bu)斷形成，将吸入室(shì)中的液體封入其(qí)中，并自吸入室沿(yán)螺杆軸向連續地(dì)推移至排出端，将(jiāng)封閉在 各空間中(zhōng)的液體不斷排出(chū)，猶如一螺母在螺(luo)紋回轉時被不斷(duan)向前推進的情形(xíng)那樣，其中螺紋圈(quan)數看做液體，當螺(luo)釘旋轉時螺紋在(zai)轉動時就相當于(yú)液體在螺杆泵裡(li)面的情形，這就是(shì)螺杆泵的基本工(gōng)作原理。螺杆與殼(ké)體之間的密封面(miàn)是一個空間曲面(miàn)。在這個曲面上存(cun)在着諸如ab或de之類(lei)的非密封區，并且(qie)與螺杆的凹槽部(bu)分形成許多三角(jiao)形的缺口abc、def。這些三(san)角形 的缺口構成(chéng)液體的通道，使主(zhu)動螺杆凹槽A與從(cong)動螺杆上的凹槽(cao)B、C相連通。而凹槽B、C又(yòu)沿着自己的螺線(xian)繞向背面， 并分别(bié)和背面的凹槽D、E相(xiàng)連通。由于在槽D、E與(yu)槽F(它屬于另一頭(tóu)螺線)相銜接的密(mi)封面上，也存在着(zhe)類似于正面的三(sān)角形缺口a’b’c’，所以D、F、E也(yě)将相通。這樣，凹槽(cao)ABCDEA也就組成一個“∞” 形(xíng)的密封空間(如采(cai)用單頭螺紋，則凹(ao)槽将順軸向盤饒(rao)螺杆，将吸排口貫(guàn)通，無法形成密封(fēng))。不難想象，在這樣(yàng)的螺杆 上，将形成(chéng)許多個獨立的“∞”形(xíng)密封空間，每一個(ge)密封空間所占有(you)的軸向長度恰好(hao)等于累杆的導程(cheng)t。因此，為了使螺杆(gan)能吸、排油口分隔(ge)開來，螺杆的螺紋(wén)段的長度至少要(yào)大于一個導程。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(luo)杆泵有以下優點(diǎn)：1)壓力和流量範圍(wei)寬闊。壓力約在3.4-340千(qian)克力/cm
