    注意事(shì)項(xiàng):1.三螺(luó)杆泵(bèng)的轉(zhuǎn)速選(xuǎn)用(yòng):三螺杆(gǎn)泵的(de)流(liú)量與轉(zhuǎn)速成線性(xìng)關系,相對于(yú)低轉(zhuǎn)速(sù)的螺杆泵,高轉速的(de)螺杆泵雖(suī)然能增加(jiā)了流(liú)量和揚程(chéng),但功(gōng)率明(míng)顯增大,高(gāo)轉速(sù)加速(sù)了轉(zhuǎn)子與定子間的(de)磨耗,必定(dìng)使螺(luó)杆泵過早失效(xiào),而且高轉速(sù)螺(luó)杆泵的定(dìng)轉子(zǐ)長度(dù)很短,極易(yì)磨損(sǔn),因(yīn)而縮短(duǎn)了(le)螺杆(gǎn)泵的使(shǐ)用壽命(mìng)。通過減(jiǎn)速機(jī)或無級調(diào)速機(jī)構來降低(dī)轉速,使勘轉速(sù)保持在每分三(sān)百轉以下(xià)較為(wéi)合理的範圍内(nèi),與高(gāo)速運轉的(de)螺杆泵(bèng)相比,使用(yòng)壽命能延長(zhǎng)幾倍。2.螺杆(gǎn)泵的品質:現在市場(chǎng)上的(de)螺杆泵的(de)種類(lèi)較多,相對(duì)而言,進(jìn)口的螺(luó)杆泵設(shè)計合理(lǐ),材質精良,但價格較高(gāo),服務方(fāng)面有(yǒu)的不(bú)到位,配(pèi)件(jiàn)價(jià)格高,訂(dìng)貨周期長,可能影響生産的正(zhèng)常運行。國内生産的(de)大都仿制進口産品,産品(pǐn)質量良(liáng)莠不齊(qí),在選用國(guó)内生産的(de)産品時,在(zài)考慮其性價比(bǐ)的時候,選用低(dī)轉速,長導程,傳動量部件(jiàn)材質(zhì)優良,額(é)定壽命(mìng)長的産品(pǐn)。3.确保雜物(wù)不進(jìn)入泵(bèng)體:濕污泥(ní)中(zhōng)混(hùn)入的固體雜物(wù)會對(duì)螺(luó)杆泵的(de)橡膠(jiāo)材質(zhì)定子(zǐ)造成損壞,所以(yǐ)确保(bǎo)雜物(wù)不進(jìn)入泵(bèng)的腔體是(shì)很重要(yào)的(de),很多污水(shuǐ)廠在泵前(qián)加裝(zhuāng)了粉碎機(jī),也有的(de)安(ān)裝格(gé)栅裝(zhuāng)置或(huò)濾網(wǎng),阻擋雜物進入(rù)螺杆泵(bèng),對于格(gé)栅應及(jí)時清撈(lāo)以免(miǎn)造成堵塞。4.保持恒定的出(chū)口壓力:螺(luó)杆泵(bèng)是一種容積式回轉泵,當(dāng)出口(kǒu)端受阻以後,壓(yā)力會(huì)逐(zhú)漸(jiàn)升高,以至于超過預(yù)定的壓力(lì)值.此時電機(jī)負荷急(jí)劇增加.傳(chuán)動機(jī)械相(xiàng)關零件的負載(zǎi)也會超出(chū)設計值,嚴重時會(huì)發(fā)生電(diàn)機燒(shāo)毀,傳動(dòng)零件斷裂.為了避(bì)免螺(luó)杆泵(bèng)損壞,一般(bān)會在(zài)三(sān)螺(luó)杆泵(bèng)出口處(chù)安裝旁(páng)通溢(yì)流閥,用以(yǐ)穩定出口(kǒu)壓力,保持泵(bèng)的正常(cháng)運轉(zhuǎn)。5.避免(miǎn)斷料(liào):三螺杆泵(bèng)決不允許(xǔ)在斷料的情形(xíng)下運轉,一(yī)經發生,橡膠定(dìng)子由(yóu)于幹磨擦,瞬間産生高溫(wēn)而燒(shāo)壞,所以(yǐ),粉(fěn)碎機完好(hǎo),格栅暢通是(shì)螺(luó)杆泵正常運轉的必(bì)要條件之一,為(wéi)此,有(yǒu)些螺杆泵(bèng)還在泵身(shēn)上安(ān)裝了斷(duàn)料停機(jī)裝置(zhì),當發(fā)生斷(duàn)料(liào)時(shí),由于螺杆(gǎn)泵其有自吸功(gōng)能的(de)特性,腔體(tǐ)内會産生真空(kōng),真空裝置(zhì)會使(shǐ)螺杆(gǎn)泵停止運(yùn)轉。5選(xuǎn)型問題:三螺杆泵選(xuǎn)型時，要盡(jìn)可(kě)能詳盡(jìn)地了解泵(bèng)的使(shǐ)用條件，除了運(yùn)行參數，如流量(liàng)，壓力(lì)需(xū)要清楚(chǔ)以外，輸送介質特性(xìng)如介質的(de)腐蝕性，含汽量，含固溶(róng)物的比率及固體顆粒(lì)的大小，以及介(jiè)質的工作(zuò)溫度(dù)，粘度，比重(zhòng)，對材(cái)料的腐蝕(shí)性等(děng)和泵(bèng)裝置(zhì)的吸(xī)入條件，安裝條件均(jun1)要了解，根(gēn)據我們(men)的經驗(yàn)，三螺(luó)杆泵選型(xíng)時應(yīng)注意以下幾點：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

    螺杆磨(mó)損五(wǔ)點原(yuán)因:1、每種塑(sù)料，都有一個理(lǐ)想塑化的(de)加工(gōng)溫度範圍(wéi)，應該(gāi)控制(zhì)料(liào)筒加工溫度，使(shǐ)之(zhī)接近(jìn)這個(gè)溫度範圍(wéi)。粒狀(zhuàng)塑料(liào)從料(liào)鬥進(jìn)入料(liào)筒，首先會(huì)到達加料(liào)段，在(zài)加料段必(bì)然會出現(xiàn)幹性(xìng)磨擦(cā)，當這些塑(sù)料受(shòu)熱不足，熔融不均時(shí)，很易(yì)造成料筒内壁及螺杆(gǎn)表面磨(mó)損增大。同(tóng)樣，在壓縮段(duàn)和均化(huà)段，如果(guǒ)塑料的(de)熔融(róng)狀态紊亂(luàn)不均，也(yě)會造成磨損增快。2、轉速(sù)應調校(xiào)得當。由于部分塑(sù)料加(jiā)有強化劑，如玻(bō)璃纖維、礦物(wù)質(zhì)或其他填(tián)充料(liào)。這些物(wù)質對金(jīn)屬材質的磨擦(cā)力往往比熔融(róng)塑料(liào)的大(dà)得多。在注塑這些塑(sù)料時，如果用高(gāo)的轉速成，則在提高對塑料的(de)剪切力(lì)的同時(shí)，亦将令強化相(xiàng)應地産生更多(duō)被撕碎的纖維(wéi)，被撕碎的(de)纖維(wéi)含有鋒利末端(duān)，令磨(mó)損(sǔn)力大為增加。無(wú)機(jī)礦物質在(zài)金屬表面(miàn)高(gāo)速(sù)滑行(háng)時，其(qí)刮削作用(yòng)也(yě)不小。所以轉(zhuǎn)速不(bú)宜調(diào)得(dé)太高。3、螺(luó)杆在(zài)機筒内轉動，物料與(yǔ)二者(zhě)的摩擦，使螺杆與機筒的(de)工作表面(miàn)逐漸磨損：螺杆(gǎn)直徑逐漸(jiàn)縮小，機筒的内(nèi)孔直徑逐漸加(jiā)大。這樣，螺(luó)杆與機筒的配合直(zhí)徑間(jiān)隙，随(suí)着二者的逐漸磨損(sǔn)而一(yī)點點加(jiā)大(dà)。可是(shì)，由于機筒(tǒng)前面機(jī)頭(tóu)和分流闆(pǎn)的(de)阻力沒有改變(biàn)，這(zhè)就增(zēng)加了被擠塑物(wù)料前進時的漏(lòu)流量，即(jí)物料從(cóng)直徑間隙(xì)處向(xiàng)進(jìn)料方向流動(dòng)量增加。結果使(shǐ)塑膠機(jī)械生産(chǎn)量下降。這種現(xiàn)象又使物料在機筒(tǒng)内停(tíng)留時(shí)間增(zēng)加，造成物(wù)料分解。如(rú)果是聚乙烯，分解産(chǎn)生的(de)氯化(huà)氫氣(qì)體(tǐ)加強(qiáng)了對螺(luó)杆和(hé)機筒(tǒng)的腐蝕。4、 物料(liào)中如有碳酸鈣和(hé)玻璃纖維(wéi)等(děng)填充料(liào)，能加快(kuài)螺(luó)杆和機筒(tǒng)的磨損。5、 由(yóu)于物(wù)料沒有塑化均(jun1)勻(yún)，或是有金屬(shǔ)異物(wù)混入料中，使螺杆轉(zhuǎn)動扭矩(jǔ)力(lì)突然增加，這種扭矩超出螺(luó)杆的強(qiáng)度極限，使(shǐ)螺杆(gǎn)扭(niǔ)斷。這是一種(zhǒng)非常規(guī)事(shì)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.
