    注意事項(xiàng):1.三螺杆泵的(de)轉速選用:三(san)螺杆泵的流(liu)量與轉速成(chéng)線性關系,相(xiàng)對于低轉速(sù)的螺杆泵,高(gāo)轉速的螺杆(gǎn)泵雖然能增(zeng)加了流量和(hé)揚程,但功率(lü)明顯增大,高(gāo)轉速加速了(le)轉子與定子(zǐ)間的磨耗,必(bì)定使螺杆泵(beng)過早失效,而(ér)且高轉速螺(luo)杆泵的定轉(zhuan)子長度很短(duǎn),極易磨損,因(yin)而縮短了螺(luó)杆泵的使用(yòng)壽命。通過減(jiǎn)速機或無級(jí)調速機構來(lái)降低轉速,使(shi)勘轉速保持(chi)在每分三百(bai)轉以下較為(wei)合理的範圍(wei)内,與高速運(yùn)轉的螺杆泵(beng)相比,使用壽(shou)命能延長幾(jǐ)倍。2.螺杆泵的(de)品質:現在市(shì)場上的螺杆(gan)泵的種類較(jiao)多,相對而言(yán),進口的螺杆(gǎn)泵設計合理(li),材質精良,但(dàn)價格較高,服(fu)務方面有的(de)不到位,配件(jiàn)價格高,訂貨(huo)周期長,可能(neng)影響生産的(de)正常運行。國(guó)内生産的大(dà)都仿制進口(kou)産品,産品質(zhì)量良莠不齊(qi),在選用國内(nèi)生産的産品(pin)時,在考慮其(qi)性價比的時(shí)候,選用低轉(zhuan)速,長導程,傳(chuán)動量部件材(cai)質優良,額定(ding)壽命長的産(chǎn)品。3.确保雜物(wu)不進入泵體(ti):濕污泥中混(hùn)入的固體雜(za)物會對螺杆(gan)泵的橡膠材(cái)質定子造成(cheng)損壞,所以确(què)保雜物不進(jin)入泵的腔體(tǐ)是很重要的(de),很多污水廠(chang)在泵前加裝(zhuāng)了粉碎機,也(ye)有的安裝格(ge)栅裝置或濾(lü)網,阻擋雜物(wù)進入螺杆泵(beng),對于格栅應(yīng)及時清撈以(yi)免造成堵塞(sai)。4.保持恒定的(de)出口壓力:螺(luó)杆泵是一種(zhong)容積式回轉(zhuan)泵,當出口端(duan)受阻以後,壓(ya)力會逐漸升(sheng)高,以至于超(chāo)過預定的壓(ya)力值.此時電(diàn)機負荷急劇(jù)增加.傳動機(ji)械相關零件(jian)的負載也會(huì)超出設計值(zhi),嚴重時會發(fā)生電機燒毀(hui),傳動零件斷(duan)裂.為了避免(miǎn)螺杆泵損壞(huai),一般會在三(sān)螺杆泵出口(kou)處安裝旁通(tōng)溢流閥,用以(yǐ)穩定出口壓(ya)力,保持泵的(de)正常運轉。5.避(bì)免斷料:三螺(luó)杆泵決不允(yun)許在斷料的(de)情形下運轉(zhuan),一經發生,橡(xiàng)膠定子由于(yu)幹磨擦,瞬間(jian)産生高溫而(ér)燒壞,所以,粉(fen)碎機完好,格(gé)栅暢通是螺(luó)杆泵正常運(yun)轉的必要條(tiáo)件之一,為此(ci),有些螺杆泵(beng)還在泵身上(shàng)安裝了斷料(liào)停機裝置,當(dāng)發生斷料時(shi),由于螺杆泵(beng)其有自吸功(gong)能的特性,腔(qiāng)體内會産生(sheng)真空,真空裝(zhuāng)置會使螺杆(gǎn)泵停止運轉(zhuǎn)。5選型問題:三(san)螺杆泵選型(xíng)時，要盡可能(néng)詳盡地了解(jiě)泵的使用條(tiao)件，除了運行(hang)參數，如流量(liang)，壓力需要清(qīng)楚以外，輸送(song)介質特性如(rú)介質的腐蝕(shí)性，含汽量，含(hán)固溶物的比(bǐ)率及固體顆(ke)粒的大小，以(yǐ)及介質的工(gōng)作溫度，粘度(du)，比重，對材料(liào)的腐蝕性等(děng)和泵裝置的(de)吸入條件，安(an)裝條件均要(yào)了解，根據我(wǒ)們的經驗，三(sān)螺杆泵選型(xíng)時應注意以(yǐ)下幾點：轉速(sù)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(gǎn)磨損五點原(yuan)因:1、每種塑料(liào)，都有一個理(lǐ)想塑化的加(jiā)工溫度範圍(wei)，應該控制料(liào)筒加工溫度(dù)，使之接近這(zhè)個溫度範圍(wéi)。粒狀塑料從(cóng)料鬥進入料(liao)筒，首先會到(dao)達加料段，在(zai)加料段必然(rán)會出現幹性(xìng)磨擦，當這些(xie)塑料受熱不(bu)足，熔融不均(jun)時，很易造成(chéng)料筒内壁及(ji)螺杆表面磨(mó)損增大。同樣(yàng)，在壓縮段和(he)均化段，如果(guǒ)塑料的熔融(róng)狀态紊亂不(bú)均，也會造成(cheng)磨損增快。2、轉(zhuǎn)速應調校得(de)當。由于部分(fen)塑料加有強(qiang)化劑，如玻璃(li)纖維、礦物質(zhi)或其他填充(chōng)料。這些物質(zhi)對金屬材質(zhi)的磨擦力往(wǎng)往比熔融塑(su)料的大得多(duō)。在注塑這些(xie)塑料時，如果(guo)用高的轉速(sù)成，則在提高(gao)對塑料的剪(jiǎn)切力的同時(shi)，亦将令強化(huà)相應地産生(shēng)更多被撕碎(sui)的纖維，被撕(si)碎的纖維含(hán)有鋒利末端(duan)，令磨損力大(da)為增加。無機(jī)礦物質在金(jīn)屬表面高速(sù)滑行時，其刮(gua)削作用也不(bú)小。所以轉速(su)不宜調得太(tài)高。3、螺杆在機(ji)筒内轉動，物(wu)料與二者的(de)摩擦，使螺杆(gǎn)與機筒的工(gōng)作表面逐漸(jian)磨損：螺杆直(zhi)徑逐漸縮小(xiao)，機筒的内孔(kong)直徑逐漸加(jiā)大。這樣，螺杆(gǎn)與機筒的配(pèi)合直徑間隙(xì)，随着二者的(de)逐漸磨損而(ér)一點點加大(dà)。可是，由于機(jī)筒前面機頭(tóu)和分流闆的(de)阻力沒有改(gǎi)變，這就增加(jia)了被擠塑物(wu)料前進時的(de)漏流量，即物(wu)料從直徑間(jian)隙處向進料(liào)方向流動量(liàng)增加。結果使(shi)塑膠機械生(sheng)産量下降。這(zhe)種現象又使(shǐ)物料在機筒(tong)内停留時間(jiān)增加，造成物(wu)料分解。如果(guo)是聚乙烯，分(fèn)解産生的氯(lü)化氫氣體加(jia)強了對螺杆(gan)和機筒的腐(fu)蝕。4、 物料中如(rú)有碳酸鈣和(he)玻璃纖維等(děng)填充料，能加(jia)快螺杆和機(ji)筒的磨損。5、 由(you)于物料沒有(you)塑化均勻，或(huò)是有金屬異(yì)物混入料中(zhōng)，使螺杆轉動(dòng)扭矩力突然(ran)增加，這種扭(niǔ)矩超出螺杆(gǎn)的強度極限(xian)，使螺杆扭斷(duan)。這是一種非(fēi)常規事故損(sun)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.
