三螺杆泵的使用維護說明和(hé)常見(jiàn)故障原因及消除方(fāng)法
使用維(wéi)護說明
啟動
①啟動前檢查全部管路法蘭、接頭的密(mì)封性,要求嚴密不(bú)漏(lòu)。
②轉動聯軸器,檢查泵的轉(zhuǎn)動是(shì)否靈(líng)活:如有别勁或卡住等不良(liáng)現象,應(yīng)拆泵排除。
③次啟動(dòng)應向泵内注入輸(shū)送液體,保證各摩擦處(chù)有足夠的潤(rùn)滑油。
④啟動前應全開吸入和排出管(guǎn)路中所有的閥(fá)們,嚴禁閉閥啟動。
⑤上述準備工(gōng)作完(wán)後,可接通電源,直接(jiē)啟動泵。
⑥嚴禁空轉運行。
維護
①如泵和電機的聲音異常(或電流表指針迅速上升(shēng))應立即停車,查出原因。
②出口(kǒu)壓力不得(dé)超過泵的工作壓力。
③安全(quán)閥(fá)在出廠前已調好,不得随意調動。
④如管路系統發生(shēng)故障,使安全閥回(huí)流,應立即停車排除(chú)故障(zhàng)。一般安全閥全回流時間不得超過三分鐘。因時間過長泵内溫度急劇(jù)升高,嚴(yán)重影響泵的壽命(mìng),甚至使泵“咬死”損壞。
⑤軸封處點滴洩漏是正常現象,如漏油量大于(yú)10毫升時(shí),應停車排除故障(zhàng)。

三螺杆泵 帕姆泵 SNH80R36E6.7W3 低(dī)噪音 微脈動
工作原(yuán)理:
由于各螺杆的相互齧合以及螺杆與襯筒内壁的緊密配(pèi)合(hé),在泵的吸入口和排出口之間,就會被分(fèn)隔成一個或多個(gè)密封空(kōng)間(jiān)。随着螺杆的轉動和齧合,這些密封空間在泵的吸(xī)入端不斷形成,将吸入室中的液體封入其中,并自吸入室沿(yán)螺杆軸向連續地推移至排出端(duān),将封閉在 各空間中的液體不斷排出,猶如一螺母在螺紋回轉時(shí)被不斷向前推(tuī)進的情形(xíng)那樣,其中螺紋(wén)圈數看做液體,當螺釘旋轉時螺紋在轉動時就相當于液體在螺杆泵裡(lǐ)面的情形,這就(jiù)是螺杆泵的基(jī)本工作原理(lǐ)。螺杆與殼體之間的密封面是一個空(kōng)間曲面。在這個曲面上存(cún)在着諸如ab或de之類的非密(mì)封區,并且與螺杆的(de)凹槽(cáo)部分形(xíng)成許多三角形的(de)缺口abc、def。這些(xiē)三角形 的缺口構成(chéng)液體的通道,使主動螺杆凹槽A與從(cóng)動螺杆上的凹槽B、C相連通。而(ér)凹槽(cáo)B、C又沿着自己的螺線繞向背面, 并分别和背面的凹槽(cáo)D、E相連通。由于在槽(cáo)D、E與槽F(它(tā)屬于另一頭螺(luó)線)相銜接的密封面上,也存在(zài)着類似于(yú)正面的三角形缺口(kǒu)a’b’c’,所以D、F、E也将相通。這樣(yàng),凹槽ABCDEA也就組成一個(gè)“∞” 形的密封(fēng)空間(如采用單頭螺紋,則凹槽将順軸向盤饒螺杆,将吸排口貫通,無(wú)法形成密封)。不難想象,在這樣的螺杆 上,将形成(chéng)許多個獨立的“∞”形密封空間,每一個(gè)密封空間所占有的軸向長(zhǎng)度(dù)恰好等于累杆的導(dǎo)程t。因此,為了使螺杆能吸、排油(yóu)口分(fèn)隔開來,螺杆的螺紋段的長度至少要大于(yú)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 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.
