液體在壓(ya)差作用下進入(rù)齧合空間容積(jī)。當容積增至最(zuì)大而形成一個(gè)密封腔時，液體(tǐ)就在一個個密(mi)封腔内連續地(dì)沿軸向移動，直(zhí)至排出腔一端(duān)。這時排出腔一(yi)端的螺杆齧合(hé)空間容積逐漸(jian)縮小，而将液體(ti)排出。三螺杆泵(bèng)的工作原理與(yǔ)齒輪泵相似，隻(zhī)是在結構上用(yong)螺杆取代了齒(chi)輪。表為各種螺(luó)杆泵的特點和(hé)應用範圍。三螺(luó)杆泵的流量和(he)壓力脈沖很小(xiao)，噪聲和振動小(xiao)，有自吸能力，但(dan)螺杆加工較困(kun)難。泵有單吸式(shì)和雙吸式兩種(zhong)結構,但單螺杆(gǎn)泵僅有單吸式(shì)。三螺杆泵必須(xu)配帶安全閥(單(dan)螺杆泵不必配(pei)帶），以防止由于(yu)某種原因如排(pái)出管堵塞使泵(bèng)的出口壓力超(chāo)過容許值而損(sǔn)壞泵或原動機(jī)。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(jie)構:三螺杆泵是(shì)利用螺杆的回(hui)轉來吸排液體(tǐ)的。中間螺杆為(wei)主動螺杆，由原(yuan)動機帶動回轉(zhuǎn)，兩邊的螺杆為(wei)從動螺杆，随主(zhu)動螺杆作反向(xiang)旋轉。主、從動螺(luó) 杆的螺紋均為(wéi)雙頭螺紋。三螺(luo)杆泵是螺杆式(shi)式容積泵。在三(sān)螺矸泵中，由于(yu)主螺杆與從動(dòng)螺杆上螺旋槽(cao)相互齧合及它(tā)們與襯套三孔(kǒng)内表面的配合(he)，得以在泵的進(jin)口與出口之間(jian)形成數級動密(mi)封室，這些動密(mi)封室将不斷把(ba)液體由泵進口(kǒu)軸向移動到泵(beng)出 口，并使所輸(shū)送液體逐級升(shēng)壓。從而形成一(yī)個連續、平穩、軸(zhóu)向移動的壓力(li)液體。三螺杆泵(beng)所輸送液體為(wéi)不含固體顆粒(li)，無腐蝕性油類(lei)及類似油的潤(run)滑性液體，粘度(dù)1.2~100oE(3.0~760cst)，高粘度液體亦(yì)可通過加溫降(jiang)粘後輸送，其溫(wen)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.  工作(zuo)原理: 螺杆泵有(yǒu)以下優點：1)壓力(li)和流量範圍寬(kuān)闊。壓力約在3.4-340千(qiān)克力/cm 2，流量可達(da)18600cm3/分；2)運送液體的(de)種類和粘度範(fan)圍寬廣；3)因為泵(beng)内的回轉部件(jian)慣性力較低，故(gù)可使用很高的(de)轉速；4)吸入性能(neng)好，具有自吸能(néng)力；5)流量均勻連(lián)續，振動小，噪音(yin)低；6)與其它回轉(zhuan)泵相比，對進入(rù)的氣體和污物(wu)不太敏感； 7)結構(gou)堅實，安裝保養(yang)容易。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 螺杆泵的(de)缺點是，螺杆的(de)加工和裝配要(yao)求較高；泵的性(xing)能對液體的粘(zhan)度變化比較敏(mǐn)感。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.
