①和離心泵(beng)相比螺杆泵(bèng)無需安裝閥(fá)門,流量是穩(wěn)定的線性流(liú)動,壓力和流(liú)量範圍寬闊(kuò)🙇♀️而且穩定,脈(mo)動很小。壓力(lì)約在 3.4-340 Kg.N /cm2 ,流量可(ke)達 18600L/min,液體在泵(bèng)作連續而勻(yun)速的直🈲線運(yun)動,無攪拌現(xiàn)象。(1) there is no need to install the valve compared with screw pump and centrifugal pump, the flow is stable linear flow, and wide range of pressure and flow stability, ripple is small.Pressure about 3.4-340 Kg. N/cm2, flow rate of up to 18600 l/min, liquid in the pump for continuous and uniform linear motion, no mixing phenomenon. ②流量與泵(bèng)的轉速成正(zheng)比,因而具有(you)良好的變量(liang)調節☀️性。(2) the flow is proportional to the pump speed, thus has a good regulatory variables. ③和柱(zhu)塞泵相比螺(luó)杆泵具有自(zi)吸能力強、吸(xi)入高度強☎️,無(wú)♌需裝置底閥(fa)抽真空的附(fù)屬設備。(3) compared with those of screw pump plunger pump self-priming capability is strong, strong suction height, without bottom valve vacuum device accessory equipment. ④和齒(chǐ)輪相比,螺杆(gǎn)泵可輸送高(gāo)粘度的物質(zhi);運送液體的(de)種類和粘度(du)範圍寬廣。(4) compared with gear, screw pump can transport high viscosity material;Wide range of delivery and type of liquid viscosity. ⑤相(xiang)互齧合的螺(luó)杆磨損甚少(shao),泵的使用壽(shòu)命長,一般滑(huá)油泵能使用(yòng)30-40年,甚至更長(zhang)。(5) mutual engagement of screw little wear and tear, long service life of pump, oil pump can be used commonly 30-40 years, or longer. ⑥泵的振動和(he)噪聲極小。The vibration and noise of the pump. ⑦因(yin)為泵内的回(hui)轉部件慣性(xìng)力較低,可在(zài)高轉速下工(gong)作。because the rotary inertia force component inside the pump is low, can work under high rotation speed. ⑧結構簡單(dan)緊湊,拆裝方(fāng)便,體積小,質(zhi)量輕。結構堅(jian)實,安裝保養(yǎng)容易。Was simple and compact structure, easy to tear open outfit, small volume, light quality.Solid structure, installation and maintenance easy. ⑨和隔膜(mó)泵相比螺杆(gǎn)泵可輸送各(ge)種混合雜質(zhì)含有氣體♌及(ji)固🌈體顆粒或(huo)纖維的介質(zhì),也可輸送各(ge)種腐蝕性物(wu)質; 對進入的(de)氣體和污物(wu)不太敏感。Pet-name ruby compared with diaphragm pump screw pump can transport all kinds of gas and solid particle mixing impurities or fiber medium, also can transport all kinds of corrosive substance;To enter a less sensitive gas and dirt. ⑩和(he)柱塞泵,隔膜(mó)泵及齒輪泵(bèng)不同的是,螺(luo)杆泵可用于(yu)藥劑填充和(hé)計量。Attending and plunger pump, diaphragm pump and the gear pump, screw pump can be used in the pharmaceutical filling and metering. 缺點:Disadvantages: ①對(dui)被輸送液體(tǐ)中的粘度變(biàn)化十分敏感(gan)。(1) is sensitive to the viscosity change of the liquid to be delivered. ②螺杆的加工(gong)精度要求高(gāo)、制造困難。(2) screw machining accuracy requirement is high, the manufacturing difficulty. |
