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(wǔ)點原因(yin):1、每種塑(sù)料，都有(you)一個理(lǐ)想塑化(hua)的加工(gong)溫度範(fan)圍，應該(gāi)控制料(liao)筒加工(gong)溫度，使(shǐ)之接近(jìn)這個溫(wen)度範圍(wéi)。粒狀塑(sù)料從料(liao)鬥進入(rù)料筒，首(shou)先會到(dao)達加料(liao)段，在加(jiā)料段必(bi)然會出(chū)現幹性(xìng)磨擦，當(dang)這些塑(su)料受熱(re)不足，熔(róng)融不均(jun)時，很易(yi)造成料(liào)筒内壁(bi)及螺杆(gǎn)表面磨(mo)損增大(dà)。同樣，在(zai)壓縮段(duan)和均化(hua)段，如果(guǒ)塑料的(de)熔融狀(zhuàng)态紊亂(luàn)不均，也(ye)會造成(cheng)磨損增(zēng)快。2、轉速(sù)應調校(xiao)得當。由(yóu)于部分(fèn)塑料加(jia)有強化(hua)劑，如玻(bo)璃纖維(wéi)、礦物質(zhi)或其他(ta)填充料(liao)。這些物(wù)質對金(jin)屬材質(zhì)的磨擦(cā)力往往(wǎng)比熔融(rong)塑料的(de)大得多(duō)。在注塑(su)這些塑(su)料時，如(rú)果用高(gāo)的轉速(su)成，則在(zài)提高對(dui)塑料的(de)剪切力(li)的同時(shi)，亦将令(lìng)強化相(xiàng)應地産(chǎn)生更多(duo)被撕碎(sui)的纖維(wei)，被撕碎(sui)的纖維(wei)含有鋒(fēng)利末端(duān)，令磨損(sun)力大為(wei)增加。無(wu)機礦物(wù)質在金(jin)屬表面(miàn)高速滑(hua)行時，其(qí)刮削作(zuo)用也不(bú)小。所以(yǐ)轉速不(bu)宜調得(dé)太高。3、螺(luó)杆在機(ji)筒内轉(zhuan)動，物料(liao)與二者(zhe)的摩擦(cā)，使螺杆(gǎn)與機筒(tǒng)的工作(zuo)表面逐(zhú)漸磨損(sun)：螺杆直(zhi)徑逐漸(jian)縮小，機(ji)筒的内(nei)孔直徑(jìng)逐漸加(jia)大。這樣(yàng)，螺杆與(yǔ)機筒的(de)配合直(zhi)徑間隙(xi)，随着二(èr)者的逐(zhú)漸磨損(sǔn)而一點(diǎn)點加大(da)。可是，由(you)于機筒(tong)前面機(jī)頭和分(fèn)流闆的(de)阻力沒(mei)有改變(biàn)，這就增(zēng)加了被(bèi)擠塑物(wù)料前進(jìn)時的漏(lou)流量，即(ji)物料從(cóng)直徑間(jiān)隙處向(xiàng)進料方(fāng)向流動(dong)量增加(jia)。結果使(shǐ)塑膠機(jī)械生産(chan)量下降(jiàng)。這種現(xian)象又使(shi)物料在(zai)機筒内(nei)停留時(shi)間增加(jiā)，造成物(wù)料分解(jie)。如果是(shi)聚乙烯(xī)，分解産(chan)生的氯(lü)化氫氣(qì)體加強(qiáng)了對螺(luó)杆和機(jī)筒的腐(fu)蝕。4、 物料(liao)中如有(yǒu)碳酸鈣(gài)和玻璃(lí)纖維等(děng)填充料(liào)，能加快(kuài)螺杆和(hé)機筒的(de)磨損。5、 由(you)于物料(liào)沒有塑(su)化均勻(yun)，或是有(yǒu)金屬異(yi)物混入(ru)料中，使(shi)螺杆轉(zhuǎn)動扭矩(jǔ)力突然(ran)增加，這(zhè)種扭矩(ju)超出螺(luo)杆的強(qiáng)度極限(xian)，使螺杆(gǎn)扭斷。這(zhè)是一種(zhong)非常規(guī)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.
