結構說明 Description of structure

1.該型泵為單級、單吸、臥式、徑向剖分，軸向吸入、徑向排出。全密封，無泄漏。

2.采用ISO2858標準，方便替代IH型、ZA型和CZ型化工流程泵。

3.工藝液體自冷卻潤滑傳動部件，不需要額外管路系統。

4.整臺泵只需1～2個密封圈，確保了運行安全。

5.優化的剛性軸結構設計，具有更佳的撓度指數，使泵的振動值進一步降低。

6.泵的軸向力主要靠葉輪上的副葉片或者平衡孔進行水力平衡，殘余軸向力由推力軸承承受。

7.采用大厚度、重載、強推力陶瓷軸承，選用高純度、高耐磨性的碳化硅材料，使用壽命長。

8.內外磁轉子均為全密封式結構，防止泵在腐蝕環境下磁體腐蝕和磁性能的衰退。

9.泵體具有底腳支撐和中心支撐（CQBH）兩種形式，供不同溫度介質時選用，基本型采用底腳支撐、低溫與高溫型采用中心支撐。

10.新型的誘導輪技術，可使泵的必需汽蝕余量更低。

11.多種循環方式將泵內產生的渦流熱和摩擦熱帶走，以滿足不同介質的輸送。典型的循環系統有：

a.內循環式。通過泵內液體壓力差形成自循環。

b.外循環式。當不宜使用泵送介質進行自潤滑冷卻時，可引入外來液體，但外來液體必須高于泵腔內的壓力0.07～0.1MPa。

12.一般無需額外的冷卻循環系統。

13.因結晶、汽化等工況需要時，可帶冷卻或保溫夾套。

14.可選擇電機直連或通過聯軸器連接的形式。

15.從驅動端看，泵為順時針方向旋轉。

16.法蘭標準可提供ANSI、HG/T20615、HG/T20592等多種選擇。

17.可配帶普通Y系列電機、YB系列防爆型電機、直流電機和永磁電機等。

1.This pump is of horizontal single stage and single suction type with radial split, axial suction and radial discharge. It is fully enclosed and leakage free.

2.It is based on ISO2858 standard, and can be conveniently used in place of type IH, ZA and CZ chemical process pumps.

3.The driving parts are cooled and lubricated by process liquid, without additional piping system.

4.In the whole pump, only 1~2 sealing rings are used, ensuring operation safety.

5.Optimized rigid shaft structure design with better deflection index has further reduced the vibration of the pump.

6.The axial load on the pump is mainly balanced hydraulically by the back blades or balance holes on the impeller, and the residual axial force is on the thrust bearing.

7.Ceramic bearings of big thickness, heavy duty and high thrust are used, and they are made with high purity and high wear resisting carborundum material, with a long service life.

8.Both internal and external magnetic rotors are in fully enclosed structure, to prevent corrosion of magnetic mass and attenuation of magnetic property with the pump in corrosive environments.

9.Pump body is available in two types: foot support and center support, for use with media of different temperature; the basic model is provided with foot support and low and high temperature types with center support.

10.New type inducer technology is adopted, to further reduce the necessary NPSH of the pump.

11.The heat produced by eddy current and friction in the pump is carried away with a number of circulation forms, to allow conveying different media. Typical circulation systems include:

a. Internal circulation. Self-circulation is formed by the liquid differential pressure within the pump.

b. External circulation. When self-lubrication and cooling with pumped media is not suitable, external liquid can be connected, provided that the incoming liquid pressure must be 0.07~0.1MPa above the pressure within the pump cavity.

12.Normally additional cooling circulation system is not required.

13.Cooling or insulation jacket can be provided when required in conditions such as crystallization and gasification.

14.Either direct driving by motor or via coupling can be used.

15.The pump rotates in a clockwise direction when viewed from the driving end.

16.A number of options for flanges to standards ANSI, HG/T20615 and HG/T20592.    

17.It can be provided with general-purpose Y series motor, YB series explosion-proof motor, DC motor and permanent magnetic motor.
