TD、TDAHorizontal Multi-Stages Style Barral Pump

General

Horizontal,multi-stages, radially split or axially split, barrel type centerline mounted multi-stages centrifugal pumps.The series pumps compile with API610 standard BB5 type.

Application

TD(A) series pumps are designed for high temperature and high pressure working conditions,especially for conditions intended to suffering thermal shock.The pump operates more reliably when pumping flammable or hazardous liquid with higher pressure.

Hydraulic model

Design

◆ Hydraulic modelsEach pump size have two or three types of hydraulic models,for different operating conditions the best efficient hydraulic model can be selected.

Balancing partsThe balancing drum balances most of the hydraulic axial forces.The residual thrust is

◆ 平衡機構:采用平衡鼓結構,平衡掉大部分的軸向力,殘余軸向力由推力軸承來承受。

 

◆ 筒體:雙層殼體結構,后拉出式設計,內殼體為段式多級或軸向剖分離心泵。筒體采用中心支撐,底部帶有定位孔。高壓時(大于15MPa)采用鍛造。

 

◆ 支撐:剛性軸,重工況承載能力的軸承支撐設計;油環潤滑的滾動軸承及滑動軸承配水冷卻或強制循環潤滑的滑動軸承。

 

◆ 管口:吸入管、吐出管壓力等級相同,均豎直向上布置。管口載荷符合API610標準。

 

◆ 軸封:密封腔體尺寸符合API682標準,配集裝式單封、雙封或串聯式機械密封。軸封只承受吸入壓力。

 

 

碳鋼,鉻鋼,鉻鉬不銹鋼。

API610標準材料等級:S-5,S-6,C-6,A-7,A-8,D-1,D-2。

根據介質特性,也可選用其它材質。

 

BB4型泵的比較優勢

BB4型單殼體節段式多級離心泵比較,有以下技術優勢:

可以承受更高的壓力。只有外筒體和泵蓋承受出口壓力,節段式內殼體僅承受壓差,避免了節段間的泄漏可能。泵蓋和筒體間有可靠的承壓墊片。

避免熱沖擊和高溫變形影響。內殼體完全浸沒在介質中,與轉子部件均勻受熱,沒有泵變形危險。泵在高溫情況下,必要時可無需預熱直接啟動。

拆卸維修方便。后拉出式結構,內殼體和轉子部件可完全抽出,無需拆卸進出口管路。

安全性好。在輸送危險介質時,由于有外筒體的結構,最大程度地減少了泄漏途徑和泄漏可能。

 

 

 

absorbed by thrust bearing.

◆ Barrel casingDouble casing,back pulling out construction,and the inner casing are section-ring casings or axially split casings. The barrel casing centerline mounted with set pin hole in the bottom. Ductile cast should be used when pressure is greater than 15MPa.

◆ Support structuresHeavy duty shaft design and bearings support having heavy duty carrying capability,roller bearings, or sleeve bearings with oil ring lubricated,water cooled,or sliding bearings with forced oil circulation.

◆ NozzleThe suction and discharge nozzied with same pressure grade are vertically arranged. Allowable nozzle loadings compile with API610.

◆ Shaft sealingThe shaft sealing chamber compiles with API682 specifications; single, double or tandem cartridge type mechanical seals are available. The pressure in seal chamber is only the same as suction.

Materials

Carbon steel, chrome steel, or Cr-Ni-Mo stainless steel.

Standard API610 material classesS-5, S-6, C-6, A-7, A-8, D-1, D-2. Other choices can be selected when needed.

Superiorities

The pump have its own superiorities compared with BB4 type pumps.

Higher pressure sustaining possibility. Only the barrel and casing cover withstand the discharge pressure, Section-ring casings only wihtstand the pressure diference,the leaking ways is minimized.The gaskets are reliable between the barrel and the casing cover.

Minimize the effect of heat shock and deformation. Both the inner casings and the rotors are surrounded by pumped liquid and uniformly heated. For high temperature operating conditions, the pump evenly permit start-up without preheating.

Easy dismantling and maintenaces. The inner unit including the casing and rotors can be removed entirely from the barrel without dismantle the piping lines.

Excellent safety. When pumping hazardous liquids, the possibility of leaking is minimized because of the barrel.
