型號說明:                 

AMP 160-120×8

AMP — 水平中開雙蝸殼式離心泵

160 — 泵設計點流量(m3/h

120 — 泵單級揚程(m)

8   — 泵級數

結構特點:

  1、AMP泵為水平中開結構型式,吸入口、吐出口均在水泵軸心線下方,與軸線垂直成水平方向,這種結構型式泵在檢修時不需拆卸進出口管路,方便拆裝檢修。

  2、葉輪為單吸閉式結構,采用背靠背對稱布置,保證轉子部件軸向力小,軸承負荷小。首級葉輪也可選用雙吸葉輪滿足大流量、低氣蝕余量工況的要求。

3、泵殼體為軸向剖分雙蝸殼結構,精鑄水力流道,過流面積大,徑向力自動平衡,大大降低軸變形量和軸承負荷。

4、殼體口環為可更換的標準整體口環,舌型固定方式,軸向剖分線位置設置防轉銷。

5、密封腔體尺寸符合API682標準,可以配置不同結構的密封及沖洗方案。足夠大的腔體空間便于密封維護或更換。

Application Range

AMP series of pumps are horizontal axially split with double volute casing centrifugal pumps. The pumps are widely applied in fields of petrochemicals, petroleum pipeline transportation, oil refinery, coal chemical industry, power plant, sea water desalination etc. Typical duties are power plant boiler feeding, oil fields water injection, ash water pump for coal chemicals, lean methanol transportation and other high pressure duties.

Performance range:

Capacity     Q:61600 m3/h  

Head       H: 1800 m

Pressure     p: 1035MPa5MPa

Temperature   t: -30200

Description of pump type:

AMP 160-120×8

AMP — Horizontal axially split double casing centrifugal pump

160  Pump design point flow (m3/h)

120 — Single stage head (m)

   8 — Pump stages

Structure Features:

1. Series AMP of pumps have horizontal axially split structure, with suction and discharge below the pump shaft center line, and vertical to the shaft line to be in horizontal direction. It facilitates easy disassembling and maintenance without moving inlet and outlet pipeline.

2. The impellor is single suction close type, with symmetrical back-to-back structure so that ensured small axial force for rotor parts, and small load to bearings. The first impellor can also be double suction to meet duty requirements of big flow and low NPSH.

3. The axially split double volute casing is with hydraulic liquid way fine casted, so that the hydraulic area is bigger, and radial force automatically balanced, which greatly reduced bearing loading and shaft distortion.

4. The casing wearing is exchangeable standard integral wearing, with tongue-type fixed. Stop pin is used on the axially split position.

5. The seal chamber size is according to API682, applicable for different structure of seal and flushing plan. Adequate chamber size is convenient for seals maintenance or exchanging.  

 

6、軸依照水力性能要求優化設計,階梯軸便于組裝,錐形軸伸便于聯軸器拆卸。大軸徑設計,轉子整體剛性好,撓度小,保證了密封環間隙,運行安全、可靠。

7、整體節流襯套,用于泄壓,降低密封腔壓力,且尺寸變化可平衡軸向力

8、整體平衡管路保證兩側密封腔工作壓力相同,不需要用戶提供輔助連接。

9、軸承體帶散熱片冷卻,也可選擇風扇冷卻,滿足高溫工況要求。安全可靠的迷宮密封環,有效的防止潤滑油泄漏和阻止灰塵等雜質進入軸承體內。

10、軸承有兩種選配,其一,徑向軸承采用滑動軸承,平衡殘余軸向力的軸承采用角接觸球軸承,最大程度滿足轉子部件強度的要求;其二,軸的徑向軸承和推力軸承均采用滾動軸承結構,徑向力由圓柱滾子軸承承受,軸向力由一對預緊的角接觸球軸承吸收,徑向力與軸向力由不同的軸承承受可大大延長軸承的使用壽命。

泵的轉向:

從驅動端看,泵順時針方向旋轉。如用戶特殊要求,也可逆時針方向旋轉。

6. The shaft is optimized designing to meet hydraulic performance requirement. The multidiameter shaft is easy for assembling, and tapered shaft extent is easy for coupling disassembling. The big shaft diameter design ensured rotor with good stiffness, small deflection, seals ring clearance, and reliable operation.

7. The whole throttle bushing is used for pressure releasing to reduce the pressure in seal chamber. And the varying of the bushing size can also balance the axial force.

8. In a whole to balance the piping to ensure same working pressure in the seal chamber on both sides. So auxiliary connection is no necessary.

9. The bearings cooling with fan or air are both available to meet high temperature duties. The reliable Labyrinth seals ring can effectively avoid lubricant leaking and ash in bearing house.

10.There are two ways of bearings fitting. One is radial bearings of sliding bearings. The angular contact ball bearings balance the residual axial force, so as to keep the rotor parts strength to a maximum extent. The other is rolling bearings for shaft radial and thrust bearing. The radial force is born through cylindrical rolling bearing while the axial force is absorbed by a pair of preloaded angular contact ball bearings. So the bearings working life can be greatly prolonged if radial and axial forces are born by different bearings.

Rotation direction of pump:

The pumps are clockwise rotating viewed from driving end. Counter clockwise is also available if required by users.
