CTD型深井筒袋磁力泵
CTD Borehole Barrel Magnetic Drivien Pump

  CTD立式多級(jí)筒袋磁力泵是我公司針對安裝空間受限和低汽蝕余量工況研制開發(fā)的一種立式懸吊式雙層殼體磁力驅(qū)動(dòng)泵，是一種深井灌裝式化工工藝用泵，該型泵參照美國石油學(xué)會(huì)API685標(biāo)準(zhǔn)設(shè)計(jì)，具有全密封、無泄漏、無污染、效率高、安全可靠、使用壽命長等特點(diǎn)，適用于輸送各種易燃易爆的、污染的、易氣化的、高溫、低溫、腐蝕性的液體，主要用于煉廠、石油化工、低溫工程、管線調(diào)壓或海上平臺(tái)、能源工業(yè)冷凝液抽取等。
CTD型泵通過內(nèi)外磁轉(zhuǎn)子進(jìn)行耦合傳動(dòng)，外磁轉(zhuǎn)子與電機(jī)直聯(lián)，隔離套將內(nèi)磁轉(zhuǎn)子密封在泵腔內(nèi)，運(yùn)用磁力驅(qū)動(dòng)技術(shù)實(shí)現(xiàn)全密封，從根本上解決了易燃易爆、有毒有害物料的輸送難題。
該型泵也可用于油田二次增壓注水，筒袋式的耐高壓外殼及隔離套，滿足泵的入口壓力較高的要求，可做到全密封、無泄漏，占地面積小。
CTD vertical multistage cylinder-bag magnetic pump is a vertical suspended 2-layer housing magnetic drive pump developed by our company for limited installation space and low net positive suction head operating conditions. It is a type of deep well grouted installation chemical engineering process pump, designed by referencing API685 standards. It features full sealing, no leakage, no pollution, high efficiency, high safety and reliability, and long service life, etc. It is suitable for the transfer of various types of inflammable, explosive, contaminating, easily gasifying, high temperature, low temperature, and corrosive liquids. It is mainly applied in refinery, petrochemical engineering, low temperature engineering, pipeline pressure regulation, and suction of condensate for offshore platform and energy industry.
CTD pump applies inner and outer magnetic rotors to provide coupled drive. The outer magnetic rotor is directly connected to the motor, the isolation sleeve seals the inner magnetic rotor inside the pump cavity, and the magnetic drive technology is used to realize full sealing, which essentially resolves the challenging situation with pumping the feed containing inflammable, explosive, toxic, and harmful substances.
This pump model can also be used for the secondary pressurized water injection in the oil field. The cylinder-bag type HP resistant housing and isolation sleeve meet the relatively high requirements on pump inlet pressure and achieve full sealing, no leakage, and small lａnd area occupied. 

結(jié)構(gòu)說明 Description of structure
1.CTD型泵為立式筒袋泵，多級(jí)徑向剖分式結(jié)構(gòu)。
2.軸向力利用水力學(xué)原理平衡，或由推力軸承及磁懸浮機(jī)構(gòu)承受。
3.外殼承受入口壓力，外殼的長度及泵的深度取決于泵的揚(yáng)程和裝置汽蝕余量的要求。
4.該泵也可以作為多級(jí)液下泵和槽罐泵以及多級(jí)管道泵使用。泵可以直接安裝在介質(zhì)池中或容器上。
5.內(nèi)置滑動(dòng)軸承為流體動(dòng)力軸承，運(yùn)行平穩(wěn)、易維護(hù)更換。
6.泵的吸入口和排出口的位置在安裝底座的上部，吸入口和排出口一般互成180°布置。
7.泵上設(shè)有方便維修的外殼排液置換管和氣相平衡接口。
8.泵芯采用可分段、便拆式結(jié)構(gòu)，使泵芯從外殼內(nèi)拔出時(shí)，可從上端分段拆下，也可分段完成裝配至外殼體內(nèi)，不會(huì)因?yàn)橐话愕膹S房高度影響到泵的拆卸和維修。
9.驅(qū)動(dòng)機(jī)可以采用與泵直聯(lián)或通過聯(lián)軸器聯(lián)接的形式。
1.CTD pump is a vertical cylinder-bag pump with multistage radial split type structure.
2.The axial force is balanced by the principle of hydraulics by thrust bearing and magnetic suspension mechanism.
3.The inlet pressure is retained by the housing. The housing length and pump depth depend on the requirements of the pump head and the net positive suction head of the equipment.
4.This pump can also be used as multistage submerged pump, tank pump, and multistage pipeline pump. This pump can be directly installed in the media pool or on the vessel.
5.The built-in sliding bearing is a hydrodynamic bearing of smooth and stable operation and easy maintenance and replacement.
6.Pump suction port and discharge port are on the upper part of the installation pedestal. Generally, they are at arranged at 180° between each other.
7.The housing liquid discharge replacing tube and gas phase equilibrium interface on this pump are provided to facilitate maintenance.
8.The pump core adopts a segmented structure which is convenient for disassembly. Therefore, when the pump core is taken out of the housing, it can be removed in segments from the upper end (while it can also be assembled into the housing in segments). Generally, the building height will not affect the pump disassembly and maintenance.
9.The drive can be connected to the pump directly or via a coupling.
