結構特點:

DSH型泵特別適用輸送高溫高壓以及易燃、易爆或有毒的液體。泵殼徑向剖分。中心線支撐設計有利于減少由于溫升而引起的負面影響。泵體設計成雙渦室,以平衡泵的徑向力。

泵體、泵蓋和密封壓蓋之間采用可控壓縮型墊片密封。密封腔的設計適合安裝所有單封、無壓和帶壓雙封等集裝機械密封,完全符合API682 (ISO21049) 的要求。

DSH泵的壓力等級為ANSI B16.5 Class300

(5MPa),符合API610的要求。

如果要求更高的壓力等級,可提供特殊設計和側進側出的DSH泵,通過修改可滿足實際工況的需求。

泵的轉向:

從原動機往泵看為逆時針方向旋轉。

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.
