W4.0), generally contain flow relief valve on the pump body, when the discharge pressure exceeds rating, has certain protective effect.There are two kinds of the direction of the import and export on the pump body, one for level, level;Secondly, level, vertical;User can choose according to their own needs. 1. 流量 Q : 作(zuò)為容積式(shì)泵,影響雙(shuang)螺杆泵流(liu)量的因素(sù)主要有轉(zhuan)速 n ,壓力 p ,以(yi)及介質的(de)粘度 v 。The selection of performance parameters: 1. The flow Q: As a positive displacement pump, double screw pump flow effects are the major factors of rotational speed n, pressure p, and the medium viscosity v. 1.1 轉速(su) n 的影響: 螺(luo)杆泵(高溫(wēn)雙螺杆泵(beng),大流量雙(shuang)螺杆泵)在(zai)工作時,兩(liang)螺杆及襯(chen)套之間形(xing)成密封腔(qiang),螺杆每轉(zhuan)動一周便(bian)由進口向(xiàng)出口移出(chu)一個密封(feng)腔,即一個(ge)密封腔的(de)體積的液(yè)體被排出(chū)去。理想狀(zhuàng)态下,泵内(nèi)部無洩漏(lòu),那麼泵的(de)流量與轉(zhuan)速成正比(bǐ)。即: Qth=n*q n---- 轉速; q---- 理(li)論排量,即(ji)泵每轉一(yi)周所排出(chu)的液體體(ti)積; Qth---- 理論排(pái)量。The influence of the rotational speed n 1.1:Screw pump (high temperature double screw pump, large flow of double screw pump) at work, the sealed cavity formed between the two screw and bushing, the screw rotation per week will remove a sealed cavity from import to export, that is, a sealed cavity volume of liquid is out.Internal leak-off ideally, pump, the pump flow rate is proportional to the speed.Namely: Qth q = n * n - speed;Q - the theory of displacement, the pump discharge by turn every week liquid volume;Qth - the theory of displacement. 1.2 壓力 △ P 的(de)影響: 雙螺(luó)杆泵(高溫(wēn)雙螺杆泵(beng),大流量雙(shuāng)螺杆泵)實(shí)際工作過(guo)程中,其内(nei)部存在洩(xie)漏,也稱滑(huá)移量。由于(yú)泵的密封(fēng)腔有一定(ding)的間隙,且(qie)密封腔前(qián)、後存在壓(yā)差 △ P ,因此,有(yǒu)一部分液(ye)體回流,即(jí)存在洩漏(lou),洩漏量用(yòng) △ Q 表示,則 Q=Qth- △ Q.顯(xiǎn)而易見,随(suí)着密封腔(qiāng)前、後壓差(cha) △ P 升高,洩漏(lòu)量 △ Q 逐漸增(zēng)大。對于不(bú)同型線和(hé)結構,影響(xiǎng)大小也各(ge)不相同。The influence of pressure delta P 1.2: Double screw pump (high temperature double screw pump, large flow of double screw pump) in the process of the actual work, its internal is leaking, also known as slippage.Due to pump seal chamber has a certain gap, and seal chamber before and after the differential delta P, as a result, some liquid reflux, is leakage, leakage in delta Q, Q = Qth - delta Q. Obviously, as the seal chamber pressure difference before and after the delta P increases, leakage delta Q increases gradually.For different lines and structure, effect size are different. 1.3 粘(zhan)度 2. 壓(ya)力 △ 與離心(xin)泵不同,雙(shuang)螺杆泵的(de)工作壓力(li) △ P 由出口負(fù)載決定,即(ji)出口阻力(lì)來決定。出(chu)口阻力與(yǔ)泵的出口(kǒu)處的壓力(li)是匹配的(de),出口阻力(li)越大,工作(zuo)壓力也越(yue)大。若想知(zhi)道壓力,則(zé)需要用流(liu)體力學的(de)知識對出(chu)口阻力精(jīng)确的計算(suàn)。2. Pressure delta P: 3. 軸功率 N : 雙(shuang)螺杆泵(高(gāo)溫雙螺杆(gǎn)泵,大流量(liàng)雙螺杆泵(bèng))的軸功率(lü)分為兩部(bù)分,即: Nth---- 液壓(ya)功率,即壓(ya)力液體的(de)能量; Nr---- 摩擦(ca)功率。3. The shaft power N: 對于(yu)确定的壓(ya)力和流量(liàng),其液壓功(gong)率是一定(ding)的,因此影(yǐng)響軸功率(lü)的因素為(wei)摩擦率 Nr 。 摩(mo)擦功率是(shì)由于運動(dòng)部件的摩(mo)擦而消耗(hao)的那部分(fèn)功率。這些(xiē)摩擦功率(lǜ)顯然是随(sui)着工作壓(ya)差的增加(jiā)而增加的(de),并且介質(zhi)粘度的增(zēng)加也會引(yǐn)起液體摩(mo)擦功率的(de)增加。 由此(cǐ),泵的軸功(gong)率除了液(ye)壓功率外(wài),其中摩擦(cā)功率随介(jie)質粘度及(ji)工作壓力(li)而增加,因(yīn)此在選擇(ze)配套電機(jī)時,介質的(de)粘度也是(shi)一個非常(cháng)重要的參(cān)考數據。尤(yóu)其在輸送(song)高粘度介(jie)質時,需要(yào)作比較精(jing)确的計算(suan)。Thus, the pump shaft power in addition to the hydraulic power, the friction power increases with medium viscosity and the pressure of work, therefore, when choosing motor medium viscosity is also a very important reference data.Especially in transport high viscosity medium, the need for accurate calculation. N(KW) N≤10 10 < N≤50 N > 50 N > 100 K 1.5 1.25 1.15 1.1 Nm=N.K Nm---- 電機功(gōng)率 N---- 軸功率(lǜ) K---- 功率儲備(bei)系數 4. 吸上(shang)性能的計(ji)算及選擇(ze) :泵(高溫雙(shuāng)螺杆泵,大(dà)流量雙螺(luo)杆泵)工作(zuo)分為以下(xia)幾個階段(duan): 4. On the absorption performance of calculation and selection: pump (high temperature double screw pump, large flow of double screw pump) work is divided into the following stages: 4.1 吸入,此時(shí)液體連續(xu)不斷地沿(yán)吸入管道(dao)移動;the liquid move continuously along the suction piping; 4.3 壓出,此時(shí)液體帶有(you)克服壓出(chū)管道系統(tong)所有阻力(lì)所必需的(de)壓力從泵(bèng)中排出。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump. 在(zài)以上三個(gè)階段中,最(zuì)為重要的(de)階段是必(bi)須保證泵(bèng)的吸上條(tiáo)件,泵才能(néng)正常工作(zuò),這是泵工(gōng)作的重要(yào)條件,否則(zé)就會發生(sheng)氣蝕,即引(yǐn)起振動,噪(zào)音等問題(ti)。 In the above three stages, the most important stage is must ensure that the suction on the condition of the pump, pump can work normally, this is the important condition of pump work, otherwise cavitation occurs, which cause vibration, noise and other issues. 5. 汽蝕餘量(liang)的計算: The calculation of NPSH: 5.1 裝(zhuāng)置汽蝕餘(yu)量 NPSHa 的計算(suan),這裡不再(zai)闡述。 5.2 想要(yào)保持泵正(zhèng)常工作,即(jí)不發生汽(qì)蝕、振動等(děng)問題,必須(xū)保證以下(xià)條件: 6. 雙(shuang)螺杆泵(高(gao)溫雙螺杆(gǎn)泵,大流量(liang)雙螺杆泵(beng))的轉速選(xuǎn)擇:Double screw pump (high temperature double screw pump, large flow of double screw pump) the speed of choice: 選擇不(bú)同的轉速(su)常牽涉以(yǐ)下問題:Choose a different speed often involve the following questions: 6.1 通(tong)過選擇合(he)适的泵轉(zhuǎn)速,以達到(dao)适當的性(xìng)能參數如(rú)流量等。by selecting the appropriate pump rotation speed, in order to achieve the appropriate performance parameters such as flow rate, etc. 6.2 随(sui)着粘度的(de)不同,泵的(de)轉速亦應(yīng)有所改變(biàn)。as the viscosity, the speed of the pump should also be changed. 轉(zhuǎn)速的選擇(zé)實質也是(shi)吸上性能(néng)的問題,尤(yóu)其是在高(gao)粘度的情(qíng)況下,如果(guǒ)轉速選得(de)過高,就會(hui)引起吸入(ru)不足,從而(er)産生噪音(yīn)和振動等(děng)問題。因此(ci)務必遵照(zhào)有關原則(ze)選擇轉速(sù)。Speed selection essence is also on the absorption performance problems, especially in the case of high viscosity, if speed selected too high, it will cause insufficient suction, so as to produce the problem such as noise and vibration.So be sure to follow relevant principles to choose speed. |
