1, SNH three screw pump is based on the national standard GB10887-89 design, manufacturing production. SNH three screw pump is a rotary pump volume, it is the use of screw meshing principle, rely on the rotation of the screw on the pump casing are mutually engaged, put by transmission medium sealed in engaging chamber, along the screw axis of continuous uniform pushed to outlet, provide a stable pressure for the system. Three screw pump for conveying a variety of non corrosive oil and lubricating oil and similar liquids. The viscosity of the liquid deliveryrange is generally 3 ~ 760mm2/S (1.2 ~ 100 ° E), high viscosity medium viscosity by heating after the delivery. The temperature less than 350 ℃.
2 according to the temperature and medium customer delivery can be used U12.1 built-in rolling bearingmechanical seal (suitable for conveying lubricating oil, hydraulic oil, lubricating oil, turbine oil, turbine oil, etc.) andE6.7 external bearing mechanical seal (suitable for conveying diesel oil, heavy oil, fuel oil, asphalt and other),available nozzle lubrication, K2 external bearings, packing seal
1, advanced structure, superior performance: to change the traditional high voltage balancing technology, from the axial force rod pressure balance device, the main force balance, uniform, screw not deformation, stable and reliable operation, no pulse, low noise; 2、 *設(shè)計(jì),密封可靠:泵采用機(jī)械密封形式,密封腔壓力與吸入壓力相通,同時(shí)結(jié)構(gòu)設(shè)計(jì)上對(duì)密封充分冷卻循環(huán),保證密封效果,無泄漏;
2, the unique design, reliable seal: pump with mechanical seal, seal chamber pressure and suction pressure is communicated, and structural design of the sealing fully cooling cycle, ensure the sealing effect, no leakage; 3、 優(yōu)化改進(jìn),外形美觀:改變傳統(tǒng)的進(jìn)、出口的位置,使得進(jìn)出口分布在泵兩側(cè)并成一條直線,外形美觀,同時(shí)在設(shè)計(jì)上進(jìn)行創(chuàng)新,在用戶現(xiàn)場(chǎng)不用改變管線就可實(shí)現(xiàn)進(jìn)出口的互換;
3, optimization, beautiful appearance: change the traditional inlet, outlet position, makes the import and exportdistribution on the pump side and into a straight line, beautiful appearance, at the same time in design innovation,without changing the pipeline can realize the exchange of import and export in the user field; 4、 泵芯組件,方便維修和配件更換:泵結(jié)構(gòu)簡(jiǎn)單緊湊,泵芯總成采用組件式結(jié)構(gòu),可整體取出,便于維護(hù)、修理;
4, pump core assembly, convenient repair and replacement parts: pump has simple and compact structure, pump core assembly uses the assembly type structure, can be taken out as a whole, convenient maintenance, repair; 5、 安全閥組件,保護(hù)產(chǎn)品安全:產(chǎn)品所配安全閥可以瞬間保護(hù)泵,防過載但不能作為管道的溢流閥使用;
5, safety valve assembly, protection products: product safety with safety valves can overload and transient protection pump,, but not as a relief valve pipeline;
6、 進(jìn)出口多種組合形式,方便現(xiàn)場(chǎng)管道連接;
6, import and export a variety of combinations, convenient fieldpipe connection; 7、 多種安裝方式,更好滿足工況安裝要求
7, different methods of installation, better meet the requirements of installation conditions
