 工作原(yuan)理(li):

   由于各螺杆的(de)相互(hu)齧合以及(ji)螺杆(gan)與襯(chen)筒内壁的(de)緊密配合，在泵(beng)的吸(xi)入口和排(pai)出口之間，就會(hui)被分(fen)隔(ge)成一個(ge)或多(duo)個(ge)密(mi)封空間。随(sui)着螺(luo)杆的(de)轉動和齧合，這(zhe)些密(mi)封(feng)空間在(zai)泵的吸入(ru)端不(bu)斷形(xing)成(cheng)，将(jiang)吸入(ru)室中的液(ye)體封入其(qi)中(zhong)，并(bing)自吸(xi)入室(shi)沿(yan)螺杆軸向連續(xu)地推移(yi)至排(pai)出端(duan)，将封閉在(zai) 各空間中(zhong)的液(ye)體(ti)不(bu)斷排(pai)出，猶(you)如一(yi)螺母(mu)在螺(luo)紋(wen)回(hui)轉時(shi)被不(bu)斷向前推(tui)進的(de)情形(xing)那樣(yang)，其中(zhong)螺(luo)紋(wen)圈數(shu)看做液體(ti)，當螺釘旋(xuan)轉(zhuan)時螺紋(wen)在轉動時(shi)就相(xiang)當于(yu)液(ye)體在螺(luo)杆泵裡面的情(qing)形，這(zhe)就(jiu)是螺杆(gan)泵的基本(ben)工作(zuo)原理(li)。螺(luo)杆與殼(ke)體之間(jian)的密封面是一(yi)個空間(jian)曲面。在(zai)這個曲(qu)面上(shang)存在(zai)着諸(zhu)如ab或(huo)de之(zhi)類(lei)的非(fei)密封(feng)區(qu)，并且與(yu)螺杆(gan)的凹槽部(bu)分形(xing)成(cheng)許多三(san)角形的缺(que)口abc、def。這(zhe)些三(san)角(jiao)形(xing) 的缺(que)口構(gou)成液(ye)體的(de)通道(dao)，使主動螺(luo)杆凹槽(cao)A與(yu)從動(dong)螺杆上(shang)的凹槽(cao)B、C相連(lian)通。而(er)凹槽(cao)B、C又沿(yan)着(zhe)自己的(de)螺線繞向(xiang)背面(mian)， 并分(fen)别(bie)和(he)背面(mian)的凹槽D、E相連通。由于(yu)在槽(cao)D、E與槽(cao)F(它屬于另(ling)一頭(tou)螺線)相銜接的(de)密封面(mian)上(shang)，也存(cun)在着類似于正(zheng)面的(de)三角形缺(que)口a’b’c’，所(suo)以D、F、E也(ye)将相(xiang)通。這樣(yang)，凹槽ABCDEA也(ye)就組(zu)成一(yi)個“∞” 形(xing)的密封空(kong)間(如采用單頭螺紋(wen)，則凹槽将順軸向盤(pan)饒(rao)螺杆，将(jiang)吸排口貫(guan)通，無(wu)法形成密封)。不(bu)難想象，在(zai)這樣的螺杆 上，将形(xing)成許多個獨立(li)的“∞”形(xing)密封(feng)空間(jian)，每一個密封空(kong)間所(suo)占有的軸(zhou)向長度(du)恰好等(deng)于累(lei)杆(gan)的導程(cheng)t。因此，為了(le)使螺杆能(neng)吸、排(pai)油口(kou)分隔(ge)開來(lai)，螺杆(gan)的螺(luo)紋段的長(zhang)度至(zhi)少(shao)要大于(yu)一個(ge)導(dao)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  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 e.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.
