●焊接三螺桿泵(螺桿輸油泵)特點
1. 三螺桿泵是一種容積式泵,它是利用相互嚙合的螺桿的旋轉把液體排送出去的辦法來進行輸送的,其壓力沒有脈動,壓力取決于該泵所串入的管路系統(tǒng)的阻圧損失或總負載。
Three screw pump is a positive displacement pump, it makes use of pitch screw
rotating liquid row out of the way to delivery, no pulse, its pressure pressure
depends on the pump series with the resistance 圧 loss or total load of pipeline
system. 2.SNH---E…Y 型泵是我公司在 SN 系列基礎上派生出來的雙層加熱泵體結構,其泵體是用鋼管和鋼板焊接而成的。在外層加熱套的水平對稱位置焊接一對蒸汽進出管,蒸汽進入加熱套內(nèi)作為傳輸液體,對所輸送的介質進行加熱及預熱(蒸汽吹掃溫度≤ 280 ℃)。該泵主要用于石油、化工、煉油廠、油庫、輸油站等行業(yè),輸送高粘度,流動性差的液體,如:重油,渣油,瀝青,原油等。 .
SNH - E...Y type pump is derived based on SN series double heat pump body structure,
the pump body is made of steel tube and steel plate welded together.At the
levels of outer heating jacket symmetric position of a pair of in and out of
the steam pipe, steam into the heating jacket as a transport liquid, heating
on the transmission medium and preheating (purge steam temperature of 280 ℃
or less).This pump is mainly used in petroleum, chemical industry, refinery,
oil depot, oil station, etc, high viscosity, illiquid liquid, such as heavy
oil, residual oil, bitumen, crude oil, etc. 性能參數(shù)范圍 :Performance

焊接三螺桿泵(螺桿輸油泵)選型要點:
1. 首先應根據(jù)油品的粘度選擇適當?shù)谋棉D速,以保證泵的 NPSH 能滿足用戶的實際吸入條件。2. 介質粘度 υ>
10000mm 2 /s 時請與我公司聯(lián)系,我公司幫助用戶選泵。 3. 從性能表中選定泵的規(guī)格及相應粘度下的壓力流量后, 可查到泵的軸功率 N ,該軸功率再加上一定的功率儲備后,作為選配電機的依據(jù),一般電機功率
N m 不小于泵軸功率 N 乘以功率儲備系數(shù) K 所得的值即: N m ≥ K · N 。 K 值由下表查得。First select the appropriate
pump speed should be based on the viscosity of the product, to ensure the pump
NPSH can satisfy the user's actual suction conditions.2. The medium viscosity
nu > 10000 mm 2 / s, please contact with our company, our company help the
user to choose the pump.3. Selected from a performance table of the specifications
of the pump and the corresponding viscosity under pressure flow, pump shaft
power can be N, the shaft power plus the power of a certain reserve, as a basis
for the matching machine, general motors power N m is not less than the pump
shaft power N times the power reserve coefficient K value: N m p k. N.K value
from the table below to check.
N(KW) | K | N ≤ 5 | 1.25 | 5 < N ≤ 10 | 1.2 | 10 < N ≤ 50 | 1.15 | N > 50 | 1.1 |
定貨須知: 由于
SNH---E…Y 型泵,必須根據(jù)使用條件,確定泵的規(guī)格,密封型號,材料,電機等,故定貨時請寫明:流量,壓力,液體的粘度,溫度等。
Because the SNH - E... Y type pump must be determined according to the conditions
of use, the specifications of the pump, seal type, material, machine, etc.,
so the order, please specify: flow, pressure, liquid viscosity, temperature,
etc. 對電機有特殊要求的還需寫明:防爆等級,防潮等級,電壓,工作環(huán)境等。
, also need to specify the special requirement of motor, explosion-proof grade,
moisture level, voltage, the work environment.
