    注(zhù)意事項:1.三螺杆(gan)泵的轉速選用(yòng):三螺杆泵的流(liú)量與轉速成線(xian)性關系,相對于(yú)低轉速的螺杆(gan)泵,高轉速的螺(luó)杆泵雖然能增(zēng)加了流量和揚(yáng)程,但功率明顯(xian)增大,高轉速加(jiā)速了轉子與定(dìng)子間的磨耗,必(bì)定使螺杆泵過(guò)早失效,而且高(gao)轉速螺杆泵的(de)定轉子長度很(hěn)短,極易磨損,因(yin)而縮短了螺杆(gǎn)泵的使用壽命(ming)。通過減速機或(huò)無級調速機構(gou)來降低轉速,使(shǐ)勘轉速保持在(zai)每分三百轉以(yǐ)下較為合理的(de)範圍内,與高速(su)運轉的螺杆泵(bèng)相比,使用壽命(mìng)能延長幾倍。2.螺(luó)杆泵的品質:現(xiàn)在市場上的螺(luo)杆泵的種類較(jiào)多,相對而言,進(jin)口的螺杆泵設(she)計合理,材質精(jing)良,但價格較高(gao),服務方面有的(de)不到位,配件價(jià)格高,訂貨周期(qi)長,可能影響生(sheng)産的正常運行(háng)。國内生産的大(dà)都仿制進口産(chǎn)品,産品質量良(liáng)莠不齊,在選用(yòng)國内生産的産(chan)品時,在考慮其(qí)性價比的時候(hou),選用低轉速,長(zhang)導程,傳動量部(bù)件材質優良,額(e)定壽命長的産(chǎn)品。3.确保雜物不(bu)進入泵體:濕污(wū)泥中混入的固(gu)體雜物會對螺(luó)杆泵的橡膠材(cái)質定子造成損(sun)壞,所以确保雜(zá)物不進入泵的(de)腔體是很重要(yao)的,很多污水廠(chang)在泵前加裝了(le)粉碎機,也有的(de)安裝格栅裝置(zhì)或濾網,阻擋雜(zá)物進入螺杆泵(bèng),對于格栅應及(jí)時清撈以免造(zao)成堵塞。4.保持恒(héng)定的出口壓力(lì):螺杆泵是一種(zhong)容積式回轉泵(bèng),當出口端受阻(zu)以後,壓力會逐(zhu)漸升高,以至于(yú)超過預定的壓(ya)力值.此時電機(ji)負荷急劇增加(jia).傳動機械相關(guan)零件的負載也(ye)會超出設計值(zhí),嚴重時會發生(sheng)電機燒毀,傳動(dong)零件斷裂.為了(le)避免螺杆泵損(sǔn)壞,一般會在三(san)螺杆泵出口處(chu)安裝旁通溢流(liu)閥,用以穩定出(chū)口壓力,保持泵(beng)的正常運轉。5.避(bi)免斷料:三螺杆(gǎn)泵決不允許在(zai)斷料的情形下(xià)運轉,一經發生(shēng),橡膠定子由于(yu)幹磨擦,瞬間産(chǎn)生高溫而燒壞(huài),所以,粉碎機完(wan)好,格栅暢通是(shi)螺杆泵正常運(yùn)轉的必要條件(jian)之一,為此,有些(xiē)螺杆泵還在泵(beng)身上安裝了斷(duan)料停機裝置,當(dāng)發生斷料時,由(you)于螺杆泵其有(you)自吸功能的特(te)性,腔體内會産(chan)生真空,真空裝(zhuāng)置會使螺杆泵(beng)停止運轉。5選型(xíng)問題:三螺杆泵(bèng)選型時，要盡可(ke)能詳盡地了解(jie)泵的使用條件(jiàn)，除了運行參數(shù)，如流量，壓力需(xū)要清楚以外，輸(shū)送介質特性如(ru)介質的腐蝕性(xing)，含汽量，含固溶(róng)物的比率及固(gu)體顆粒的大小(xiǎo)，以及介質的工(gōng)作溫度，粘度，比(bǐ)重，對材料的腐(fu)蝕性等和泵裝(zhuang)置的吸入條件(jian)，安裝條件均要(yao)了解，根據我們(men)的經驗，三螺杆(gan)泵選型時應注(zhù)意以下幾點：轉(zhuan)速的選擇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(gan)磨損五點原因(yīn):1、每種塑料，都有(yǒu)一個理想塑化(hua)的加工溫度範(fàn)圍，應該控制料(liào)筒加工溫度，使(shi)之接近這個溫(wen)度範圍。粒狀塑(sù)料從料鬥進入(rù)料筒，首先會到(dào)達加料段，在加(jiā)料段必然會出(chū)現幹性磨擦，當(dang)這些塑料受熱(rè)不足，熔融不均(jun)時，很易造成料(liao)筒内壁及螺杆(gǎn)表面磨損增大(dà)。同樣，在壓縮段(duàn)和均化段，如果(guǒ)塑料的熔融狀(zhuàng)态紊亂不均，也(yě)會造成磨損增(zeng)快。2、轉速應調校(xiao)得當。由于部分(fèn)塑料加有強化(huà)劑，如玻璃纖維(wéi)、礦物質或其他(tā)填充料。這些物(wù)質對金屬材質(zhì)的磨擦力往往(wǎng)比熔融塑料的(de)大得多。在注塑(sù)這些塑料時，如(ru)果用高的轉速(sù)成，則在提高對(duì)塑料的剪切力(li)的同時，亦将令(lìng)強化相應地産(chǎn)生更多被撕碎(suì)的纖維，被撕碎(suì)的纖維含有鋒(feng)利末端，令磨損(sǔn)力大為增加。無(wu)機礦物質在金(jīn)屬表面高速滑(huá)行時，其刮削作(zuo)用也不小。所以(yi)轉速不宜調得(de)太高。3、螺杆在機(ji)筒内轉動，物料(liao)與二者的摩擦(ca)，使螺杆與機筒(tong)的工作表面逐(zhú)漸磨損：螺杆直(zhí)徑逐漸縮小，機(jī)筒的内孔直徑(jing)逐漸加大。這樣(yàng)，螺杆與機筒的(de)配合直徑間隙(xì)，随着二者的逐(zhú)漸磨損而一點(dian)點加大。可是，由(yóu)于機筒前面機(ji)頭和分流闆的(de)阻力沒有改變(biàn)，這就增加了被(bei)擠塑物料前進(jìn)時的漏流量，即(ji)物料從直徑間(jian)隙處向進料方(fang)向流動量增加(jiā)。結果使塑膠機(jī)械生産量下降(jiang)。這種現象又使(shi)物料在機筒内(nei)停留時間增加(jia)，造成物料分解(jie)。如果是聚乙烯(xī)，分解産生的氯(lü)化氫氣體加強(qiang)了對螺杆和機(ji)筒的腐蝕。4、 物料(liào)中如有碳酸鈣(gai)和玻璃纖維等(děng)填充料，能加快(kuài)螺杆和機筒的(de)磨損。5、 由于物料(liào)沒有塑化均勻(yún)，或是有金屬異(yì)物混入料中，使(shi)螺杆轉動扭矩(ju)力突然增加，這(zhe)種扭矩超出螺(luo)杆的強度極限(xiàn)，使螺杆扭斷。這(zhe)是一種非常規(guī)事故損壞。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.
