1、雙層殼體結(jié)構(gòu)，外殼承受入口壓力，進出口位于同一水平線上，可作為多級管道泵或去掉外殼作為槽罐泵使用。
With two-casing structure, the outer casing bears inlet pressure. Inlet and outlet are at same level. It can be used as multi-stage pipeline pump or groove pump by removing the casing.
2、 首級葉輪為吸入式葉輪，提高抗汽蝕性能；特殊工況，可設(shè)計加裝誘導(dǎo)輪，以降低汽蝕余量。
First-stage impeller is suction one, which enhances anti-cavitation performance. Under special working conditions, inducer can be designed and installed to reduce NPSH.
3、 加大軸承箱儲油室，帶有獨立循環(huán)的自動潤滑系統(tǒng)；軸承部件集成化設(shè)計，拆卸組裝方便。
With oil chamber with enlarged bearing casing and independent and cyclic automatic lubrication system. With integrated design of bearing parts, it is convenient in dismantling and assembling.
4、采用平衡盤裝置平衡軸向力，殘余軸向力由配對的向心推力球軸承承受。
Balance axial force with balance disk. The residual axial force is undertaken by paired radial-thrust ball bearing.
5、 選用增強型剛性軸，整體無接點；下部配置流體動力滑動軸承，線速小、磨損輕，減少運轉(zhuǎn)振動。
Select enhanced rigid shaft, it’s overall contactless. Fluid dynamic sliding bearing is configured below
with low line speed, slight wear and reduction in revolving vibration.
6、采用便拆型電機支架，帶加長段膜片聯(lián)軸器，不必拆卸電機即可進行軸承
部件、密封部件和平衡裝置的維修更換。
With convenient-to-dismantle TV support and diaphragm coupler with lengthened segment, it is
not necessary to dismantle motor to repair and replace bearing and sealing parts and balancing device.
7、 管口按API標準三倍載荷設(shè)計，確保運轉(zhuǎn)安全、穩(wěn)定、可靠。
Pipe orifice is designed according to API standard twofold load. API standard chassis is adopted
to ensure safe, stable and reliable operation.
8、按API682標準密封腔設(shè)計，采用集裝式機械密封，便于安裝和維修，
軸向壓縮量不受任何連接件軸向尺寸影響，無需調(diào)整。
Packaging-type mechanical seal is adopted according to seal design of API682 standard. It is conve
-nient in installation and maintenance. The axial compression is free of influences of axial dimensions of
any connecting pieces. It is not necessary to make adjustment.
