3GR螺桿泵工作原理與特點(diǎn)
3GR screw pump working principle and characteristics
3GR螺桿泵是利用螺桿的回轉(zhuǎn)來(lái)吸排液體的。主、從動(dòng)螺桿的螺紋均為雙頭螺紋。由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合,在泵的吸入口和排出口之間,就會(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)和嚙合,這些密封空間在泵的吸入端不斷形成,將吸入室中的液體封入其中,并自吸入室沿螺桿軸向連續(xù)地推移至排出端,將封閉在各空間中的液體不斷排出,猶如一螺母在螺紋回轉(zhuǎn)時(shí)被不斷向前推進(jìn)的情形那樣,這就是3GR螺桿泵的基本工作原理。
3GR screw pump is used to suck the liquid rotary screw. The main, driven screw threads are double headed screw. Due to the mutual engagement of the screw and the screw and tube wall lining closely with, the pump suction port and exhaust port, will be separated into one ormore of the sealed space. With the rotating screw and meshing, the sealed space in the pump suction side evolving, the suction chamber of liquid filled therein, and a suction chamber along the screw axis continuous passage to the discharge end, will be closed in thespace continuous discharge of liquid, like a nut in screw rotation is constantly moving forwardthis is the case3GR the basic principle of the screw pump.
從上述工作原理可以看出,3GR螺桿泵有以下優(yōu)點(diǎn):
Can be seen from the above works, 3GR screw pump has the following advantages:
1)壓力和流量范圍寬闊。壓力約在3.4-340千克力/cm2,流量可達(dá)18600cm3/分;
1) a wide range of pressure and flow. Pressure of about 3.4-340 KGF /cm2, flow up to 18600cm3/ min;
2)運(yùn)送液體的種類(lèi)和粘度范圍寬廣;
2) the delivery of liquid type and a wide range of viscosity;
3)因?yàn)楸脙?nèi)的回轉(zhuǎn)部件慣性力較低,故可使用很高的轉(zhuǎn)速;
3) because of the rotary inertia force components in the pump is low, it can use very high speed;
4)吸入性能好,具有自吸能力;
4) inhalation of good performance, with self absorption capacity;
5)流量均勻連續(xù),振動(dòng)小,噪音低;
5) continuous uniform flow, small vibration, low noise;
6)與其它回轉(zhuǎn)泵相比,對(duì)進(jìn)入的氣體和污物不太敏感;
6) when compared with other rotary pump, less sensitive to gas and dirt entering the;
7)結(jié)構(gòu)堅(jiān)實(shí),安裝保養(yǎng)容易。
7) the structure of a solid, easy installation and maintenance.
3GR螺桿泵的缺點(diǎn)是,螺桿的加工和裝配要求較高;泵的性能對(duì)液體的粘度變化比較敏感。
盡管三3GR螺桿泵有諸多優(yōu)勢(shì),但若選型不當(dāng),則不僅得不到滿(mǎn)意的運(yùn)行效果,而且會(huì)導(dǎo)致泵的噪音和振動(dòng),甚至嚴(yán)重?fù)p壞泵的內(nèi)部零件,使泵系統(tǒng) 不能正常工作,因此,選型人員應(yīng)多方慎重考慮,合理選型 ,必要時(shí)應(yīng)向我公司技術(shù)部門(mén)咨詢(xún)。三3GR螺桿泵選型時(shí),要盡可能詳盡地了解泵的使用條件,除了運(yùn)行參數(shù),如流量 ,壓力需要清楚以外,輸送介質(zhì)的特性如介質(zhì)的腐蝕性,含汽量,含固溶物的比率及固體顆粒的大小,以及介質(zhì)的工作溫度,粘度,比重,對(duì)材料的腐蝕性等和泵裝置的吸入條件,安裝條件均要了解,根據(jù)我們的經(jīng)驗(yàn),
3GR the disadvantage is that the screw pump, screw machining and assembly demanding;more sensitive to the change of fluid viscosity pump performance
Although the three 3GR screw pump has many advantages, but if the improper selection, not only not to run a satisfying effect, but will lead to the vibration and noise of pump, or even seriously damage the internal parts of the pump, the pump system can not work normally,therefore, selection should be more party carefully consideration, reasonable selection, when necessary should consult technical service department of our company. Three 3GR screwpump selection, to be as detailed as possible understanding of the pump operating conditions, in addition to operating parameters, such as flow rate, pressure needs to beclear, the conveying medium properties such as corrosive medium, steam content, containingsolids and the ratio of the size of the solid particles, and the operating temperature, the viscosity of the medium, specific gravity, suction conditions on corrosion resistance and pump device materials, installation conditions are to understand, according to our experience
三、3GR螺桿泵選型 時(shí)應(yīng)注意以下幾點(diǎn):
3GR screw pump selection should pay attention to the following points:
1. 泵轉(zhuǎn)速的選擇
1 pump speed selection
1.1 以輸送介質(zhì)粘度和泵的規(guī)格確定轉(zhuǎn)速范圍:
1.1 to the transmission medium viscosity and pump specifications to determine the speed range:
輸送高粘度介質(zhì)時(shí),泵應(yīng)選低轉(zhuǎn)速,若粘度較低,相應(yīng)可選擇高轉(zhuǎn)速:介質(zhì)粘度> 20°E 時(shí),對(duì)于大規(guī)格的泵(主桿外徑60mm 以上),轉(zhuǎn)速以970rpm 或720rpm 為宜,如果粘度更高(粘度>80°E )如粘膠液,可降低轉(zhuǎn)速使用,* 200-500rpm ;
The transport of high viscosity medium, the pump should be selected the low speed, if theviscosity is low, the corresponding choice of high speed: medium viscosity '20 ° E, thespecifications of the pump (above the main rod diameter 60mm), the speed with 970rpm or720rpm is appropriate, if higher viscosity (viscosity >80 ° E) such as viscose reduce speed,can use, recommended 200-500rpm;
對(duì)于小規(guī)格的泵,介質(zhì)粘度>20°E 時(shí),轉(zhuǎn)速以1450rpm 或970rpm 為宜,如果粘度更高(粘度>80°E ),可降低轉(zhuǎn)速使用,*300-600rpm ;
For the small size of the pump, medium viscosity >20 ° E, speed to 1450rpm or 970rpm is appropriate, if higher viscosity (viscosity >80 ° E), can reduce speed to use, recommended 300-600rpm;
1.2 由于泵的轉(zhuǎn)速越高,在相同性能參數(shù)下,泵的體積就越小,但由于轉(zhuǎn)速高,摩擦功率高,泵的磨損就大,壽命就短,如果輸送介質(zhì)的潤(rùn)滑性比較差或含有微量雜質(zhì),應(yīng)選擇較低轉(zhuǎn)速,以使泵保持較長(zhǎng)的壽命,*在1450rpm 以下。
1.2 because of the higher speed of the pump, in the same performance parameters, the smaller size of the pump, but because of high speed, high power pump friction, wear and tear on the big, short life, if the transmission medium relatively poor lubrication or contain trace impurities, should choose low speed, so that the pump to maintain the longer life, recommendbelow 1450rpm
2. 結(jié)構(gòu)的選擇可根據(jù)泵的安裝和使用條件參3GR螺桿泵的系列和型式來(lái)進(jìn)行,原則上:
2 structure can choose according to installation of the pump and the use of reference condition three 3GR screw pump series and types are, in principle
2.1 輸送潤(rùn)滑性油類(lèi),溫度在80°C 以下選擇內(nèi)置結(jié)構(gòu)的泵;
A 2.1 conveying lubricating oils, choice of internal structure of pump temperature below 80 ° C;
2.2 溫度超過(guò)80°C 或輸送介質(zhì)潤(rùn)滑性差時(shí),選擇外置 軸承 結(jié)構(gòu)的泵;
2.2 temperature exceeds 80 ° C or conveying medium poor lubrication, select the external bearing structure of pump;
2.3 輸送流動(dòng)性差,粘度較高的介質(zhì)或需要所輸送介質(zhì)進(jìn)行加熱或保溫時(shí)選擇雙層加熱泵體結(jié)構(gòu)的泵;
2.3 the transport mobility is poor, medium or high viscosity media transport needs of theselection of heating or insulation layer structure of heat pump pump;
2.4 高溫輸送時(shí),應(yīng)選擇耐高溫的材料所制成的泵,請(qǐng)與我廠。
2.4 high temperature pipeline, should choose the high temperature resistant material pump,please contact with my factory.
3. 泵材料組合的選擇:
