1、   SNH三螺桿泵產(chǎn)品概述簡介：

SNH三螺桿泵是無脈動(dòng)軸向輸送具有一定潤滑性介質(zhì)的定量容積式低壓轉(zhuǎn)子泵，適于輸送燃料油、潤滑油、液壓油、礦物油等油類和具有潤滑性的流動(dòng)性液體。所輸送的介質(zhì)中不得含有任何磨料顆粒和對(duì)泵材料有腐蝕的物質(zhì)。SNH系列三螺桿泵由特殊型線（擺線）構(gòu)成的螺旋型面，當(dāng)電機(jī)或馬達(dá)驅(qū)動(dòng)主動(dòng)螺桿轉(zhuǎn)動(dòng)時(shí)，其不斷運(yùn)動(dòng)的各個(gè)密封腔室逐漸形成真空，液體在大氣壓的作用下由吸入口吸入并沿軸向連續(xù)、無脈動(dòng)的輸送到排出口，無攪拌、乳化現(xiàn)象。形成排出壓力的能力取決于系統(tǒng)負(fù)載和螺桿密封腔的數(shù)量，同時(shí)也與輸送介質(zhì)的粘度以及驅(qū)動(dòng)轉(zhuǎn)速也有一定的關(guān)系。

SNH三螺桿泵的主動(dòng)螺桿和從動(dòng)螺桿采用液壓平衡裝置，被輸送的液體在泵腔內(nèi)做連續(xù)、勻速的軸向直線運(yùn)動(dòng)，無脈動(dòng)，噪音低，運(yùn)轉(zhuǎn)平穩(wěn)，流量壓力穩(wěn)定，工作平穩(wěn)，振動(dòng)小。

SNH三螺桿泵的零部件通用互換性好，可以任意拆解，更換相應(yīng)的零部件。泵零件少，結(jié)構(gòu)簡單，重量輕，安裝、使用、維修方便，效率高，壽命長。

三螺桿泵的從動(dòng)螺桿的軸向力支撐在后蓋或主動(dòng)螺桿上，并由液壓力驅(qū)動(dòng)旋轉(zhuǎn)，從動(dòng)螺桿由液壓力驅(qū)動(dòng)，，主動(dòng)螺桿和從動(dòng)螺桿之間沒有機(jī)械接觸，螺桿之間，螺桿和泵套之間皆有油膜保護(hù)，因而螺桿型面僅傳遞液壓扭矩，并不受力，也無磨損和機(jī)械摩擦，對(duì)全部傳動(dòng)零件而言，均由被輸送介質(zhì)形成的油膜保護(hù)和潤滑。

三螺桿泵的主桿的徑向旋轉(zhuǎn)跳動(dòng)由平衡活塞套也可以叫滑動(dòng)軸承定位，且借助于平衡活塞和軸套的間隙使高壓腔和密封腔分開，在密封腔內(nèi)裝有機(jī)械密封，無泄漏，腔內(nèi)的油液回油孔與泵的吸入腔相通，因而不受排出壓力的影響。

具有很強(qiáng)的自吸能力，節(jié)能低耗，不需要底閥及每次開機(jī)前灌油。

組合系列化有多種結(jié)構(gòu)，可用于臥式（H），法蘭式（F）和立式（S）浸油式（J）以及懸掛式(K)安裝。

根據(jù)所輸送介質(zhì)需要還可提供加熱或冷卻結(jié)構(gòu)。

對(duì)于潤滑性相對(duì)較差的介質(zhì)，可以采用軸承外置結(jié)構(gòu)（W1）以及金屬波紋管密封。保證三螺桿泵優(yōu)良的使用壽命。

為了保護(hù)泵、電機(jī)和管路系統(tǒng)，泵必須帶有外置或內(nèi)置安全閥裝置。
可輸送介質(zhì)種類：

A  潤滑性液體：液壓油，礦物油，機(jī)械油，潤滑油，淬火油，齒輪油，變壓器油，汽輪機(jī)油，水乙二醇，原油，動(dòng)植物油等

B  低潤滑性液體：輕柴油，重柴油，燃油，燃料油，重油，渣油，含臘稀油，冷卻液，皂化液等

C  粘性液體：各種合成橡膠液，人造膠液，乳化液等

SNH initiative three screw screw screw and driven by hydraulic balancing device, the liquid in the pump chamber is fed continuously to do, uniform axial linear motion, no pulse, low noise, smooth operation, flow pressure stable, smooth, vibration.

SNH three screw generic interchangeability of parts, which could be disassembled, replace the corresponding parts. Pump parts, simple structure, light weight, easy to install, use, maintenance, high efficiency, long life.

Axial force supporting three screw driven screw on the back cover or active screw driven by a hydraulic pressure rotating, driven screw driven by fluid pressure, there is no mechanical contact between the screw and the initiative driven screw, screw the Individually film protection, which passed between the surface between screw type, screw and hydraulic torque pump sets only, not by force, and no mechanical wear and friction, for all transmission parts, the film is transported by the formation of protective medium and lubrication.

Three main radial screw rod rotation beating balanced by the piston sleeve can also be called sliding bearing positioning and balance clearance between the piston and sleeve by means of high-pressure chamber and sealing chamber separately in a sealed chamber equipped with a mechanical seal, no leakage , the oil return hole cavity pump suction chamber communicating with, and therefore not affected by the pressure of the discharge.

Has a strong self-absorption capacity, low energy, no bottom valve and filling the oil before each start.

The series combination of a variety of structures can be used in horizontal (H), flange (F) and vertical (S) oil immersion formula (J) and suspended (K) installed.

May need to provide heating or cooling structure according to the transmission medium.

For the relatively poor lubrication media, you can use an external bearing structure (W1) and metal bellows seal. Three screw ensure good life.

To protect pumps, motors and piping systems, pumps must have external or internal valve devices.
Can transport media types:

A lubricating fluid: hydraulic oil, mineral oil, mechanical oil, lubricating oil, quenching oil, gear oil, transformer oil, turbine oil, water glycol, oil, animal and vegetable oil

B low lubricity liquids: light diesel oil, heavy diesel oil, fuel oil, fuel oil, heavy oil, residual oil, wax-containing light oil, coolant, and other fluid saponification

C viscous liquid: liquid synthetic rubber, synthetic glue, emulsion, etc.
