SN系列三螺杆泵

SN系列三螺杆泵
产品先容

SN系列三螺杆泵 - 产品先容:

ejiamp /意嘉牌SN系列三螺杆泵液在压差下进入啮合空间体积。当体积增加到最大值以形成密封室时,液体在密封室内轴向连续移动直到室的一端。此时,放电室一端的螺旋啮合空间体积逐渐减小,液体被排出。除了齿轮由结构中的螺钉代替之外,三螺杆泵的工作原理类似于齿轮泵的工作原理。该表显示了各种螺杆泵的特性和应用范围。三螺杆泵具有小流量和压力脉冲,低噪音和振动,以及自吸能力,但螺杆加工困难。该泵具有单吸式和双吸式,但单螺杆泵只有一种吸入式。三螺杆泵必须配备安全阀(单螺杆泵不必配备皮带),以防止泵或原动机因某些原因(例如排放管堵塞)而损坏泵出口压力超过允许值。

SN系列三螺杆泵结构:

SN系列三螺杆泵利用螺杆的旋转来吸入和排出液体。中间螺杆是主动螺杆,由原动机驱动,两侧螺杆为从动螺杆,与主动螺杆反向旋转。主螺钉和从动螺钉的螺纹是双头螺纹。
三螺杆泵它是一种螺杆式正排量泵。在三螺杆泵中,由于主螺杆和从动螺杆上的螺旋槽相互啮合并且它们与套管的三个孔的内表面配合,在入口之间形成多个动态密封室。和泵的出口,形成这些动态密封。腔室将连续地将液体从泵入口移动到泵出口并逐步增加输送的液体。从而形成连续,平滑,轴向移动的压力液体。由三螺杆泵输送的液体是不含固体颗粒,无腐蚀性油等的润滑液,高粘度液体也可通过加热和降低粘度输送,温度不超过150℃ 。

SN系列三螺杆泵 - 工作原理:

由于螺钉的相互接合以及螺钉与衬套内壁的紧密配合,在泵的吸入口和排出口之间,它被分成一个或多个密封空间。随着螺杆的旋转和接合,这些密封空间连续地形成在泵的吸入端,并且吸入室中的液体被密封在其中,并且从螺杆的轴向方向上的吸入室连续地推动到排放端,在每个空间关闭。液体连续排出,好像在螺纹旋转时螺母连续推进一样。螺纹数被认为是液体,当螺杆旋转时,螺纹在旋转时相当于液体。在螺杆泵的情况下,这是螺杆泵的基本工作原理。
螺钉和壳体之间的密封表面是空间弯曲表面。在该弯曲表面上存在诸如ab或de的非密封区域,并且多个三角形凹口abc,def与螺钉的凹槽部分形成。这些三角形凹口形成液体通道,允许主动螺旋槽A与从动螺杆上的凹槽B,C连通。凹槽B和C沿其自身的螺旋线缠绕到背面,并分别与背面的凹槽D和E连通。由于凹槽D,E和凹槽F(属于另一个头螺旋)通过类似于前表面的三角形凹口a'b'c'彼此连接,因此D,F和E也将连通。这样,凹槽ABCDEA也构成“∞”形密封空间(如果使用单头螺纹,凹槽将沿轴向拧紧,吸入口和排出口将通过,不能形成印章)。不难想象,在这种螺钉上,将形成多个独立的“∞”形密封空间,每个密封空间占据的轴向长度恰好等于疲劳杆的导程t。因此,为了分离螺杆吸入口和排出口,螺杆的螺纹部分的长度至少大于一个引线。SN系列三螺杆泵的特点和优点:

(1)压力和流量范围宽,流量范围0.2-320 m3 / h,最大工作压力可达5 MPa;
(2)输送液的粘度和粘度范围宽,粘度范围为1mm2 / s-760mm2 / s;
(3)由于三螺杆泵中旋转部件的惯性力低,可以使用高转速;
(4)吸入性能好,自吸能力强;
(5)流量均匀连续,振动小,噪音低,几乎没有脉动;
(6)三螺杆泵结构坚固,易于安装(水平,垂直,法兰和插入式)。
(7)三螺杆泵耐热性强,一般工作温度为(1~250℃)。
(8)根据要运输的介质,还可以提供加热或冷却结构;
(9)三螺杆泵几乎没有磨损,只要选择正确,三螺杆泵的使用寿命就很长。
(10)三螺杆泵工作效率高
