结构特点:

DSH型泵特别适用输送高温高压以及易燃、易爆或有毒的液体。泵壳径向剖分。中心线支撑设计有利于减少由于温升而引起的负面影响。泵体设计成双涡室,以平衡泵的径向力。

泵体、泵盖和密封压盖之间采用可控压缩型垫片密封。密封腔的设计适合安装所有单封、无压和带压双封等集装机械密封,完全符合API682 (ISO21049) 的要求。

DSH泵的压力等级为ANSI B16.5 Class300

(5MPa),符合API610的要求。

如果要求更高的压力等级,可提供特殊设计和侧进侧出的DSH泵,通过修改可满足实际工况的需求。

泵的转向:

从原动机往泵看为逆时针方向旋转。

Design Features:

Series DSH pumps are especially suitable for pumping high temperature high pressure and inflammable,explosive or toxic fluids. Have a radially split case construction. Centerline mounting is utilized to minimize thermally induced misalignment. All sizes are double volute to balance radial force.

Fully confined gaskets betweencase, cover and seal gland plate. Seal chamber designed to accommodate all single,unpressurized and pressurized dual cartridge seal configurations; complies fully with API 682 specification (ISO 21049).

For API 610 compliance, with standard pressure class ratings equivalent to ANSI B16.5 Class300(5MPa).

For higher pressure ratings, side-side suction discharge nozzles and other special applications the DSH is supplemented, which can be modified to suit virtually any application.

Pump Rotation:

Rotation is counterclockwise when viewed from the coupling end.
