    1、安裝前(qián)應檢查泵的油封(feng)是否良好，并檢查(cha)泵在運輸中是否(fǒu)損壞，可用手轉動(dòng)聯軸器是否有卡(kǎ)勁現象，如💚有則應(yīng)拆泵進行清洗，修(xiu)理和校正。1, before installation should check whether the oil seal of the pump is good, and check the pump is damaged in transportation, turn the coupling usable hand card trouble phenomenon, if there is any should tear open pump for cleaning, repair and calibration.2、安裝泵(bèng)的進油和排油管(guǎn)道時，其管徑不得(de)小于泵的✏️進油🙇🏻和(he)📐出油口口徑，進油(yóu)管道不得過長，彎(wān)頭不得過多，否則(ze)将影響泵的💚工作(zuò)狀态。2, installation of pump suction and discharge of oil pipe, the pipe diameter shall not be less than the oil inlet of the pump and the oil outlet diameter, inlet pipe shall not be too long, elbow shall not too much, otherwise will affect the pump working condition.3、當有兩台以(yi)上的泵安裝在同(tong)一條主管線上，為(wei)便于泵的啟動，在(zài)近泵的排油管上(shàng)必須安裝逆止閥(fá)。3, when more than two head of pump installed in the same line, to facilitate pump start-up, in close to the oil drain pump must be installed on a non-return valve.4、對于在較高溫度(dù)（指60℃以上）下輸送粘(zhān)度大的油類（如：重(zhòng)油）的備用泵，必須(xū)是熱🌈備用泵，否則(ze)泵在低溫下啟動(dòng)會造成電機過載(zǎi)或泵損壞。（建議在(zai)靠近✏️泵的排油管(guan)上的逆止閥旁，并(bing)聯♈安裝一個小回(hui)流閥，對備用泵可(kě)微啟回流⛱️閥，使泵(bèng)緩慢逆轉，其逆轉(zhuan)速≤100轉/分，使部分熱(re)油經常流過泵内(nèi)，達到泵熱備用目(mù)的）。4, for under high temperature (above 60 ℃) conveying the viscosity of oil (such as: heavy oil) of the standby pump, it must be hot standby pump, otherwise the pump at low temperature can cause the damage of motor overload or pump.(suggest near the exhaust non-return valve on the tubing pump, a small return valve installed in parallel, differentiable and the backflow preventer to standby pump, the pump slow reversal, the reverse speed 100 r/min or less, often make some hot oil flows through the pump, to pump hot standby purposes).5、輸送介質内含(hán)有機械雜質。将嚴(yan)重影響泵的運轉(zhuan)🌂和降☁️低使用壽命(ming)，因此在泵安裝前(qián)，必須仔細清除☔進(jin)油管内的焊渣，沙(shā)粒等雜質，并應在(zai)進油管道靠近泵(beng)處🙇🏻安裝濾器，濾器(qi)網孔大❤️小，可根據(jù)工作情況及介質(zhì)粘度确定。（一般可(ke)用40~80目網），過濾面積(jī)一般不得小于進(jin)油管橫截面積的(de)20倍。5, mechanical impurity is contained within the transmission medium.Will seriously affect the operation and reduce the service life of pump, so before the pump installation, must be carefully clean up the feed tube welding slag, impurities such as grains of sand, and shall be installed in the inlet pipe near the pump filter, filter mesh size, is decided according to the working condition and medium viscosity.Available (40 ~ 80 mesh net), filter area generally shall not be less than 20 times into the cross-sectional area of the tubing 6、盡量在泵進油(you)和排油口處的螺(luó)紋孔上連接壓力(lì)表❗和真空表，以便(biàn)于觀察泵的運轉(zhuan)狀态。6, as far as possible in the pump suction and discharge of oil on the threaded hole mouth connect pressure gauge and vacuum gauge, in order to observe the pump running state.7、原動機與泵(beng)的轉軸必須在同(tóng)一中心線上，可用(yòng)直㊙️尺測隙規在聯(lián)軸器圓周上間隔(gé)90°處檢查。8、原動機與(yu)泵的轉向必須一(yī)緻，嚴格禁止原動(dòng)機驅動泵逆轉。電(diàn)機接線時，應先脫(tuo)開電機與泵的聯(lian)軸❄️器，對電機🏃🏻作試(shi)運轉。使其🤞轉向與(yu)泵的轉向标志一(yī)緻。7, prime mover and the pump shaft must be in the same center line, available ruler feeler gauge in the coupling of the circumference of a circle by 90 ° in check.8, steering engine and pump must be consistent, strictly prohibited prime motor driven pump reversal.Electrical wiring, should first release coupling of motor and pump, a test run on the motor.The steering pump and steering sign agreement.

    工作原理:

    由于(yú)各螺杆的相互齧(niè)合以及螺杆與襯(chen)筒内壁的🐅緊密配(pèi)合，在泵的吸入口(kǒu)和排出口之間，就(jiu)會被分🧡隔成一個(ge)或多個密封空⛷️間(jian)。随着螺杆的轉動(dong)和齧合，這些密封(feng)空間在泵的吸入(ru)端不斷形成，将吸(xī)入室中的液🔆體封(feng)入其中，并自吸入(ru)室沿螺杆軸向連(lián)🌂續地推移至排出(chū)端，将封閉在 各空(kōng)間中的液體不斷(duan)排出，猶如一螺母(mǔ)在螺紋回⚽轉時被(bèi)不斷向前推進的(de)情形那樣，其中螺(luó)紋圈數看做🤩液體(ti)，當螺釘旋轉時螺(luo)紋在轉動時就相(xiang)當于液體在螺杆(gǎn)泵裡面的情形，這(zhe)就是螺杆泵的基(ji)本工作原理。螺杆(gǎn)與殼🛀🏻體之間的密(mi)封面♌是一個空間(jian)曲面。在這個曲面(mian)上存在着諸如ab或(huo)de之類的非密封區(qu)，并且與螺杆的凹(āo)槽部分形成許多(duō)三角🚶形的缺口abc、def。這(zhè)些三角形 的缺口(kou)構成液體的通道(dào)，使主動螺杆凹槽(cáo)A與從動螺杆上的(de)凹槽B、C相連通。而凹(ao)槽B、C又沿着自己的(de)螺線繞向背面， 并(bing)分别和背面的凹(ao)槽D、E相連通。由于在(zai)槽D、E與槽F(它屬于另(ling)一頭螺線)相銜接(jiē)的密封面上，也存(cún)在着類似于正面(mian)的三角形缺口a’b’c’，所(suǒ)以D、F、E也将相通。這樣(yàng)，凹槽ABCDEA也就組成一(yi)個“∞” 形的密封空間(jian)(如采用單頭螺紋(wén)，則凹槽将順軸向(xiang)盤饒螺杆，将吸排(pai)口貫通，無法形成(chéng)密封)。不難想象，在(zài)這樣的螺杆 上，将(jiāng)形成許多個獨立(lì)的“∞”形密封空間，每(mei)一個密封空間所(suo)占有的軸向長度(du)恰好等于累杆的(de)導程t。因此，為了使(shǐ)螺杆能吸、排油口(kǒu)分隔開來，螺杆的(de)螺紋段的長度至(zhì)少要大于一個導(dao)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.

    螺杆泵的缺(que)點是，螺杆的加工(gong)和裝配要求較高(gāo)；泵的性能🈲對液體(ti)的粘度變化比較(jiao)敏感。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.

    螺杆泵具(jù)有以下優點：1．和離(li)心泵相比螺杆泵(beng)無需安裝閥們流(liu)量是穩定的線性(xìng)流動;2． 和柱塞泵相(xiàng)比螺杆泵具有自(zì)吸能力強、吸入高(gāo)度強;3．和隔膜泵相(xiang)比螺杆泵可輸送(song)各種混合雜質含(han)有氣體及固體顆(kē)粒或纖維的介質(zhi)，也可輸送各種腐(fu)蝕性物質;4． 和齒輪(lun)相比，螺杆泵可輸(shū)送高粘度的物質(zhì);5．和柱塞泵，隔膜泵(bèng)及齒輪泵不同的(de)是，螺杆泵可用于(yu)藥劑填充和計量(liàng).Screw pump has the following advantages: 1. Compared with screw pump and centrifugal pump doesn't need to install the valve flow is stable linear flow;2. Compared with those of screw pump plunger pump self-priming capability is strong, strong suction height;3.

  注意事(shì)項:1.三螺(luó)杆泵的轉速選用(yòng):三螺杆(gǎn)泵的流量與轉速(su)成線性關系,相對于低轉(zhuǎn)速的螺杆泵,高轉速的螺(luo)杆泵雖然能增加(jia)了流量和揚程,但功率明(ming)顯增大,高轉速加速了轉(zhuan)子與定子間的磨(mo)耗,必定(dìng)使螺杆泵過早失(shi)效,而且(qiě)高轉速螺杆泵的(de)定轉子長度很短(duan),極易磨(mo)損,因而(ér)縮短了螺杆泵的(de)使用壽命。通過減(jiǎn)速機或無級調速(sù)機✏️構來降低轉速(sù),使勘轉(zhuan)速保持在每分三(sān)百轉以下較為合(he)理的範🚶‍♀️圍内,與高速運轉(zhuan)的螺杆泵相比,使用壽命(ming)能延長幾倍。2.螺杆泵的品(pin)質:現在(zai)市場上的螺杆泵(beng)的種類較多,相對而言,進口的螺(luó)杆泵設計合理,材質精良(liáng),但價格(gé)較高,服(fu)務方面有的不到(dao)位,配件(jiàn)價格高,訂貨周期長,可能影響生(shēng)産的正常運行。國(guó)内生産的大都仿(páng)制進🐇口産品,産品質量良(liang)莠不齊,在選用國内生産(chan)的産品時,在考慮其性價(jia)比的時候,選用低轉速,長導程,傳動量部(bu)件材質優良,額定壽命長(zhǎng)的産品。3.确保雜物不進入(ru)泵體:濕(shi)污泥中混入的固(gù)體雜物會對螺杆(gǎn)泵的橡膠材質定(ding)子造成損壞,所以确保雜(zá)物不進入泵的腔(qiāng)體是很重要的,很多污水(shuǐ)廠在泵前加裝了(le)粉碎機,也有的安裝格栅(shān)裝置或濾網,阻擋雜物進(jìn)入螺杆泵,對于格栅應及(jí)時清撈以免造成(chéng)堵塞。4.保(bǎo)持恒定的出口壓(yā)力:螺杆(gan)泵是一種容積式(shì)回轉泵,當出口端受阻以(yǐ)後,壓力(lì)會逐漸升高,以至于超過(guò)預定的壓力值.此時電機(jī)負荷急劇增加.傳動機械(xie)相關零件的負載(zǎi)也會超出設計值(zhí),嚴重時(shi)會發生電機燒毀(huì),傳動零(líng)件斷裂.為了避免螺杆泵(bèng)損壞,一(yī)般會在三螺杆泵(bèng)出口處安裝旁通(tōng)溢流閥,用以穩定出口壓(yā)力,保持(chi)泵的正常運轉。5.避免斷料(liào):三螺杆(gan)泵決不允許在斷(duàn)料的情形下運轉(zhuǎn),一經發(fa)生,橡膠(jiao)定子由于幹磨擦(ca),瞬間産(chan)生高溫而燒壞,所以,粉碎機完好(hao),格栅暢(chàng)通是螺杆泵正常(chang)運轉的必要條件(jian)之一,為(wei)此,有些(xiē)螺杆泵還在泵身(shēn)上安裝了斷料停(ting)機裝置,當發生斷料時,由于螺杆(gan)泵其有自吸功能(neng)的特性,腔體内會産生真(zhēn)空,真空(kōng)裝置會使螺杆泵(bèng)停止運轉。5選型問題:三螺杆泵選(xuan)型時，要盡可能詳(xiáng)盡地了解泵的使(shǐ)用條件，除了運行(hang)參數，如流量，壓力(li)需要清楚以外，輸(shu)送介質的🌍特性😍如(rú)介質的腐蝕性，含(hán)汽量，含固溶物的(de)比率及固體顆粒(lì)的🔴大小，以及介質(zhì)♍的工作溫度，粘度(dù)，比重，對材料的腐(fǔ)蝕性等和泵裝置(zhi)的吸入條件，安裝(zhuāng)條件均要了解，
