三(sān)螺杆泵 帕姆泵 snh80r36e6.7w3 低噪(zào)音(yīn) 微(wēi)脈動(dòng)

 工作原理(lǐ):

   由于(yú)各螺(luó)杆的相互(hù)齧合以及螺杆(gǎn)與襯(chèn)筒内壁的(de)緊密(mì)配合，在泵的吸入(rù)口和排(pái)出口之間，就會被分隔成(chéng)一個(gè)或多(duō)個密封空(kōng)間。随(suí)着螺(luó)杆的(de)轉動(dòng)和(hé)齧合，這(zhè)些密封空間在(zài)泵的吸入(rù)端不斷形成，将吸入(rù)室中(zhōng)的液體封入其中，并自吸(xī)入室(shì)沿螺杆軸向連(lián)續地推移(yí)至排出端(duān)，将封(fēng)閉在(zài) 各空間中(zhōng)的液體(tǐ)不(bú)斷排(pái)出，猶如(rú)一(yī)螺母(mǔ)在螺(luó)紋回轉時(shí)被不(bú)斷向前推(tuī)進的情形那樣，其中(zhōng)螺紋圈數(shù)看做液體，當螺釘旋(xuán)轉時(shí)螺紋(wén)在轉(zhuǎn)動時就相當于(yú)液(yè)體在螺杆泵裡(lǐ)面(miàn)的情(qíng)形，這(zhè)就是(shì)螺杆(gǎn)泵的基本工作原理。螺杆與殼(ké)體之間的密封(fēng)面是(shì)一個(gè)空間(jiān)曲面。在這個曲(qǔ)面上(shàng)存在着諸如ab或(huò)de之類(lèi)的非(fēi)密封區，并且與(yǔ)螺杆的凹槽部分形成許多三(sān)角形的缺(quē)口abc、def。這(zhè)些三角形 的缺(quē)口構成(chéng)液(yè)體的(de)通道，使主(zhǔ)動螺(luó)杆凹槽a與從動螺杆(gǎn)上的凹槽(cáo)b、c相連通。而(ér)凹槽b、c又沿着自己(jǐ)的(de)螺線繞(rào)向(xiàng)背面(miàn)， 并分别和背面的凹槽(cáo)d、e相(xiàng)連通。由于在槽d、e與槽(cáo)f(它屬于另(lìng)一頭(tóu)螺線(xiàn))相銜(xián)接的密封(fēng)面上，也存(cún)在着(zhe)類(lèi)似(sì)于正面(miàn)的三角形缺(quē)口a’b’c’，所(suǒ)以d、f、e也将相通。這樣，凹槽abcdea也就組(zǔ)成一個“∞” 形(xíng)的密封(fēng)空間(如(rú)采用(yòng)單頭螺紋(wén)，則凹槽将(jiāng)順軸向盤(pán)饒螺杆，将(jiāng)吸排口(kǒu)貫(guàn)通，無(wú)法形成密封)。不難(nán)想象，在(zài)這樣(yàng)的螺杆 上，将(jiāng)形(xíng)成許多個(gè)獨立(lì)的“∞”形(xíng)密封空間(jiān)，每一(yī)個(gè)密封空(kōng)間所占有的軸(zhóu)向長度恰好等(děng)于累杆的導程(chéng)t。因此，為(wéi)了(le)使螺(luó)杆能吸、排(pái)油口(kǒu)分隔開來，螺杆(gǎn)的螺紋段的長(zhǎng)度至少要大于一個(gè)導(dǎo)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  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.
