    注意(yì)事項(xiàng):1.三螺杆泵的轉(zhuǎn)速選(xuǎn)用(yòng):三螺杆(gǎn)泵的(de)流量與轉(zhuǎn)速成線性關系(xì),相對(duì)于低(dī)轉速(sù)的螺杆泵(bèng),高轉(zhuǎn)速的(de)螺(luó)杆(gǎn)泵雖(suī)然能(néng)增加(jiā)了流量和揚程,但功(gōng)率明(míng)顯增大,高(gāo)轉速加速了轉子與定子間的(de)磨耗,必定使螺(luó)杆泵過早失效(xiào),而且高轉速(sù)螺(luó)杆泵的(de)定轉子長度很短,極易(yì)磨損(sǔn),因而(ér)縮短(duǎn)了螺(luó)杆泵的使(shǐ)用壽(shòu)命。通(tōng)過減(jiǎn)速機或無(wú)級調(diào)速機構(gòu)來降低(dī)轉速(sù),使勘轉速保持(chí)在每分三(sān)百轉以下較為(wéi)合理的範(fàn)圍内,與高速運轉的(de)螺杆泵相比,使(shǐ)用壽(shòu)命(mìng)能延長(zhǎng)幾倍。2.螺杆泵的(de)品質:現在市場(chǎng)上的螺杆泵的種類(lèi)較多(duō),相對(duì)而言,進口的螺杆泵(bèng)設計合(hé)理,材質精(jīng)良,但價(jià)格較高(gāo),服務方面有的不到位(wèi),配件價格高,訂(dìng)貨周期長,可(kě)能影響生産(chǎn)的正(zhèng)常運行(háng)。國内生産的大都仿制(zhì)進(jìn)口(kǒu)産(chǎn)品,産品質量(liàng)良(liáng)莠不齊(qí),在選用國内生(shēng)産的(de)産品(pǐn)時,在(zài)考慮(lǜ)其性(xìng)價比(bǐ)的時候,選用低(dī)轉速,長導程,傳動量(liàng)部(bù)件材質(zhì)優良(liáng),額定壽命(mìng)長的(de)産品(pǐn)。3.确保(bǎo)雜物(wù)不進入泵體:濕污泥中(zhōng)混(hùn)入的固體(tǐ)雜物(wù)會對螺(luó)杆泵的(de)橡膠材質(zhì)定子(zǐ)造成損壞,所以(yǐ)确保雜物不(bú)進入泵(bèng)的腔體是(shì)很重要(yào)的,很多(duō)污水(shuǐ)廠在泵前(qián)加(jiā)裝了粉碎機(jī),也有(yǒu)的安裝(zhuāng)格(gé)栅裝(zhuāng)置(zhì)或濾網(wǎng),阻擋雜(zá)物進入(rù)螺杆泵,對于格(gé)栅應及(jí)時清撈(lāo)以免造成堵塞。4.保持恒定(dìng)的出(chū)口壓力:螺(luó)杆泵(bèng)是一(yī)種容積式(shì)回轉泵(bèng),當(dāng)出口(kǒu)端受阻以後,壓(yā)力會(huì)逐漸升高(gāo),以至于超過預(yù)定的(de)壓力(lì)值.此(cǐ)時電機負(fù)荷急(jí)劇增加.傳動機(jī)械相關(guān)零件的(de)負載也會(huì)超出(chū)設計(jì)值(zhí),嚴重時(shí)會(huì)發生電機燒毀,傳(chuán)動(dòng)零件斷(duàn)裂.為了避(bì)免螺(luó)杆泵損壞,一般(bān)會在三(sān)螺(luó)杆泵(bèng)出口處(chù)安裝旁(páng)通溢流閥,用以(yǐ)穩定出口(kǒu)壓力(lì),保持泵的正常運轉(zhuǎn)。5.避免斷料(liào):三螺杆泵(bèng)決不(bú)允許在斷料的(de)情形(xíng)下運轉,一(yī)經發生,橡膠定子由(yóu)于幹磨擦,瞬(shùn)間(jiān)産生高溫(wēn)而燒壞,所以(yǐ),粉碎機完好(hǎo),格栅(shān)暢通是(shì)螺(luó)杆泵(bèng)正常(cháng)運轉(zhuǎn)的必要(yào)條件之一,為此,有些螺(luó)杆泵(bèng)還在泵(bèng)身(shēn)上安裝了斷(duàn)料停機(jī)裝置,當發生斷(duàn)料時(shí),由于螺杆(gǎn)泵其有(yǒu)自吸功能的特性,腔體(tǐ)内會(huì)産生真空(kōng),真空(kōng)裝置會使(shǐ)螺(luó)杆泵停止運(yùn)轉。5選型問題:三螺杆泵選(xuǎn)型時(shí)，要盡(jìn)可能(néng)詳盡地了(le)解(jiě)泵的使(shǐ)用(yòng)條件，除了運(yùn)行參數(shù)，如流(liú)量，壓力需要清楚(chǔ)以外，輸送(sòng)介質特性如介(jiè)質的(de)腐蝕性，含(hán)汽量，含固溶物的比(bǐ)率及固(gù)體顆粒(lì)的大小(xiǎo)，以及介質的工作溫度(dù)，粘度，比重，對材(cái)料的腐(fǔ)蝕(shí)性(xìng)等(děng)和泵裝置的吸入條件，安裝條(tiáo)件均要了(le)解，根(gēn)據我們(men)的經驗(yàn)，三螺(luó)杆泵選型(xíng)時應注(zhù)意以下幾點：轉(zhuǎn)速的選(xuǎn)擇note: 1. the three screw pump speed selection: a linear relationship with three-screw pump flow rate and rotational speed, low relative to the rotating speed of screw pump, high rotational speed of screw pump, although can increase the flow and head but power obviously increase, high speed accelerate the abrasion between the rotor and stator, must make the premature failure of screw pump, and the high speed of the screw pump stator length is short, easy to wear and tear, thus shortening the service life of the screw pump.through reducer or stepless speed regulation mechanism to reduce the speed, keep to determine speed at three hundred revolutions per minute (the following reasonable range, compared with the high speed of screw pump, can prolong service life of a few times.2. the quality of the screw pump, now in the market is more, the kinds of screw pump, screw pump imported from rational design, excellent material, but the price is higher, the service aspect some do not reach the designated position, accessories price is high, the order cycle is long, may affect the normal running of production.domestic production of generic mostly imported products, product quality is good and bad are intermingled, when choosing the products of the domestic, considering its cost-effective, choose low rotation speed, long lead, transmission quantity of parts material is good, rated life long product.3. ensure that stuff does not enter the pump body: wet sludge mixed with solid debris can cause damage to the rubber stator of screw pump, so make sure debris into the cavity of the pump is not very important, a lot of sewage plant in front of the pump with a grinder, also some installation or mesh grille device, stop the debris into screw pump, the grating should be timely get so as not to cause congestion.4. maintain a constant outlet pressure: screw pump is a kind of positive displacement rotary pump, when after the outlet is blocked, the pressure will gradually rise, so that more than a predetermined pressure value. the motor load increases sharply. transmission machinery and related parts load will exceed the design value, serious happens when the motor is burnt, transmission parts fracture. in order to avoid damage of screw pump, typically, bypass the overflow valve is installed on the three screw pump outlet to stable outlet pressure, maintain the normal operation of the pump.5. avoid cutting: three screw pump must not be allowed in the case of the cutting operation, once happened, the rubber stator due to dry friction, instant high temperature and burn out, so, crushing machine in good condition, grille flow is one of the necessary conditions for normal operation of the screw pump, therefore, some screw pump on pump installation end stop device, when cutting, due to the characteristics of the screw pump has a self-priming function, can produce vacuum chamber, vacuum device can make the screw pump stop running.5 selection problem: three screw pump selection, should understand the using condition of pump as much detail as possible, in addition to the operating parameters, such as flow rate, pressure needs to be clear, the characteristics of medium such as corrosive medium, gas content, including ratio of solid solution and the size of the solid particles, as well as the working temperature, medium viscosity, density, corrosion of materials and pump suction conditions, such as the installation conditions are to understand, according to our experience, three screw pump selection should pay attention to the following:the choice of speed

    螺杆(gǎn)磨(mó)損五點(diǎn)原(yuán)因:1、每(měi)種塑(sù)料，都(dōu)有一(yī)個理想塑化的加工(gōng)溫度範圍(wéi)，應該(gāi)控制料筒(tǒng)加工(gōng)溫度，使之(zhī)接近這個溫度範圍(wéi)。粒狀塑料(liào)從料(liào)鬥進入料筒，首(shǒu)先會(huì)到達加料(liào)段，在加料段必(bì)然會出現(xiàn)幹性磨擦(cā)，當這(zhè)些塑料受熱不(bú)足，熔(róng)融不(bú)均時，很易(yì)造(zào)成料筒(tǒng)内壁(bì)及螺(luó)杆表面(miàn)磨(mó)損增大(dà)。同(tóng)樣，在(zài)壓縮段和均化(huà)段，如果塑料的(de)熔融狀态紊亂(luàn)不均，也會造成磨損(sǔn)增快。2、轉速(sù)應調校(xiào)得(dé)當。由于部分塑料加(jiā)有(yǒu)強化(huà)劑(jì)，如玻璃纖維、礦物(wù)質(zhì)或其他填(tián)充料。這些(xiē)物質對金(jīn)屬材質(zhì)的磨擦力往往(wǎng)比熔融(róng)塑料的(de)大(dà)得多(duō)。在注(zhù)塑這些塑(sù)料時，如果(guǒ)用高的轉(zhuǎn)速成，則在(zài)提高對塑料的(de)剪切(qiē)力的同(tóng)時(shí)，亦将(jiāng)令強(qiáng)化相(xiàng)應地産生更多(duō)被撕(sī)碎的纖維(wéi)，被撕碎的纖維(wéi)含有(yǒu)鋒利末(mò)端(duān)，令磨損力(lì)大為(wéi)增加。無機(jī)礦物(wù)質在金屬表面(miàn)高速滑行時，其(qí)刮削作用(yòng)也不(bú)小。所以轉速不(bú)宜調得(dé)太高。3、螺杆在機筒内轉動，物(wù)料與二者(zhě)的摩擦(cā)，使(shǐ)螺(luó)杆與機筒(tǒng)的工作(zuò)表面逐漸(jiàn)磨損(sǔn)：螺杆(gǎn)直徑逐漸(jiàn)縮小，機(jī)筒(tǒng)的内(nèi)孔直(zhí)徑逐漸加大。這樣，螺杆與(yǔ)機筒的配合直(zhí)徑間(jiān)隙，随着二者的逐漸磨損(sǔn)而一點點加大。可是(shì)，由于機筒(tǒng)前面機頭(tóu)和分(fèn)流闆(pǎn)的阻力沒(méi)有改(gǎi)變，這就增(zēng)加了被擠塑物(wù)料前進時的漏(lòu)流量，即物料從(cóng)直徑間隙處向(xiàng)進料方(fāng)向流動(dòng)量增加。結果使(shǐ)塑膠(jiāo)機械生産(chǎn)量下降。這種現(xiàn)象又(yòu)使物料在機筒内停留時(shí)間增(zēng)加，造成物(wù)料分解。如果是(shì)聚乙烯(xī)，分(fèn)解産(chǎn)生的(de)氯化氫氣(qì)體加(jiā)強了對螺(luó)杆和機筒的腐(fǔ)蝕。4、 物(wù)料(liào)中如有(yǒu)碳酸鈣(gài)和玻璃纖維(wéi)等填充料(liào)，能加快(kuài)螺杆和(hé)機筒的磨損。5、 由于物(wù)料沒(méi)有塑(sù)化均(jun1)勻(yún)，或是有金屬異(yì)物(wù)混入料中(zhōng)，使螺杆轉(zhuǎn)動扭矩力突然增加(jiā)，這種(zhǒng)扭矩超出螺(luó)杆的強度極限，使螺杆(gǎn)扭斷。這(zhè)是一種(zhǒng)非常(cháng)規事故損(sǔn)壞。screw wear five reasons: 1, each type of plastic, there is a ideal plasticizing processing temperature range, temperature should be controlled cylinder processing, make it close to the temperature range.granular plastic from the hopper into the cylinder, will first reach the feeding section, the charging period of inevitable dry friction, when the plastic is heated, fused inequality, very easy to cause the inner wall of the cylinder and the screw surface wear.similarly, in compression and homogenization, if uneven plastic molten state of disorder, can cause wear faster.2, rotational speed should be proper calibration.as part of the plastic with enhancer, such as glass fiber, minerals, or other filling material.the material of metal friction often is much bigger than the molten plastic.when these plastic injection molding, if with high speed, is in the increase of plastic shear force at the same time, will also strengthen accordingly produce more fiber is torn, torn fiber containing sharp end, the wear and tear strength increased greatly.inorganic minerals in the metal surface high-speed taxi, scraping effect is also not small.so the speed shoulds not be too high.3, screw rotation inside the barrel, friction material with both the screw and barrel of the surface of the work gradually wear: screw diameter reduced gradually, the barrel inner hole diameter increase gradually.in this way, the atching of the screw and barrel diameter clearance, with the gradual wear and tear of the a little bit more., however, because of the barrel in front of the nose and shunt plate resistance has not changed, which adds to the forward extrusion material leakage flow, the material feeding direction from diameter clearance flow has increased.results decreased plastic machinery production.this phenomenon and make the material stay in the barrel time increased, the material break down.if it is polyethylene, decomposition of hydrogen chloride gas is used to strengthen the corrosion of the screw and barrel.4, material such as calcium carbonate and the filling material such as glass fiber, can speed up the screw and barrel of the wear and tear.5, as there is no uniform plasticizing, material or metal foreign bodies with material, to rotate the screw torque force suddenly increases, the torque beyond the ultimate strength of the screw, the screw twist off.this is a kind of unconventional accident damage.
