三螺杆泵優點與缺點(Diǎn)
發布時間:2014-11-18 16:58:17 點擊次數[Shù]:

 ①和離心泵相比螺杆泵無[Wú]需安裝閥[Fá]門,◇流◇量(Liàng)是穩定的線(Xiàn)性流動,壓力和流量範圍寬闊而▽且▽穩定,脈動很小。壓▾力▾約在 3.4-340 Kg.N /cm2 ,流量可達 18600L/min,液體[Tǐ]在泵作(Zuò)連續而勻速的直(Zhí)線運[Yùn]動,無攪拌現象。(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流量與泵的▽轉▽◆速◆成正比,因而具有良好的變[Biàn]量調節性。(2) the flow is proportional to the pump speed, thus has a good regulatory variables.
    ③和柱塞泵相比螺杆泵▲具▲有自吸能力強、吸入高度強,無需裝[Zhuāng]置底(Dǐ)閥抽真空的附(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和齒輪相比(Bǐ),螺杆泵可輸(Shū)送高粘度的(De)物質;運送液[Yè]體的種類和粘度(Dù)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相互(Hù)齧合的螺杆磨(Mó)損甚少,泵的⋄使⋄用壽命長,一般滑油泵能使用30-40年,甚至更長。(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泵的振動和噪聲(Shēng)極小。The vibration and noise of the pump.
    ⑦因為泵内▾的▾回轉部件慣性力較▾低▾,可在(Zài)高轉速下工作。because the rotary inertia force component inside the pump is low, can work under high rotation speed.
    ⑧結構簡▽單▽緊湊,拆裝方便,體積(Jī)小,質量輕。結構堅實,安裝保養(Yǎng)容[Róng]易。Was simple and compact structure, easy to tear open outfit, small volume, light quality.Solid structure, installation and maintenance easy.
    ⑨和隔膜泵相▾比▾螺杆泵可[Kě]輸(Shū)送各[Gè]種混合(Hé)雜質含有氣體及固體顆粒[Lì]或纖維的介質,也[Yě]可輸送各種腐蝕[Shí]性物質; 對進入的[De]氣(Qì)體◊和◊污物不太敏感。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和柱塞泵,隔膜泵及齒輪泵不同的是,螺杆泵可用于藥劑填充和計量。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[Duì]被輸送液體中[Zhōng]的粘度變化十分敏感。(1) is sensitive to the viscosity change of the liquid to be delivered.
    ②螺杆的(De)加工精度要(Yào)求高、制造困難。(2) screw machining accuracy requirement is high, the manufacturing difficulty.
