2.2W.W TWIN SCREW PUMP
Briefintroduction
On the base of deeply researching overseas adcancde technique,according to the present-day practical demands of gas-oil mixed transporting,2W.WH--type out board bearing double suction dualscrew multtiphase mixed transporting pump and 2W.Wseries double screw pump are researched and deceloped by our company,then we follow the regulations of the national standard GB11035-89 and produced it.Through engagement together between dricing srew and driwen screw and the match between screw andpump body hole,and then form many sealing empty cacities,when the screw is rotational,these sealin empty cavitiel move ahead continually,push the liquid in the sealing cavity to the exit and then discharged,so the purpose of transporting the liquid can bei relized.
Its working principle is as chart 1
The advantage of the twin-screw pump
1、Transporting the liquid smoothly without any disturbing and pulsation,no impulse,with less vibration and low noise.
2、It has strong selr-suction performance,when multiphase mixed transporting,the gas content can not over 80%,and the san content can not over 500g/m3.
3、Outboard bearing structure which qdopt independently lubricate,so aoo kinds of nonlubricate medium can be transported.
4、It adopts synchronous gear drinving,between the two totors there is no touch at all,ecen though idling for short term is no problem.
5、The pump body has heating jacket,so it can transport all kinds of clean or low viscosity or high viscosity mediuum which contain the particulate solids.(the diameter of the particulate is usually less than 0.12-0.2mm)
6、If selecting the material correctly,some corrosive medium can be transported.
7、Double-suction structure,and there is no axial force on the rotor.
8、The shaft ends adopt mechanical seal or corrugated pipe mechanical seal,it has the characteristic of long-life,less leak,wide scope of application.
Performance scope
1、The highest pressure 4.0MPa
2、 Capacity range 1~1000m3/h
3、Temperature range -20~120℃
4、Thee ciscosity of the medium 1~3000mm2/s,when lower the speed of the rotation it can be up to 106mm2/s
The viscosity of the medium will largely influende the twin screw pump,the nominal discharge of the pump means the discharge under the certain ciscosity condition,in order to ensure the pump to work on the high efficiency working condition,wehn the test is not enough,we suggest to select the speed of the fotation according to the following viscosity.
The viscosity of the mediumcSt Speed r/min
<400 1500
400 ~1200 1000
1200~3600 750
When the viscosity of the medium is higher , the customer should contact with the manufacturer for the speed of rotation and motor power.
Application example
1、Oil field:Used as the multiphase mixed transporting pump and crude oil transporting pump and the like which can transport oil,gas,water,tiny solid particullate.
2、shipbuilding:Using as marine loading pump,ballast pump an sewage treatment pump , main machine lubricating pump and fuel oil pump.
3、Petrochemical industry:Using as loading and transporting pump which can transport all kinds of resin,pigment , paraffinwax,paint,rinting ink,emulsoid,all kinds of oil crude oil,hesvy oil and the like.
4、Power plant:Using as heavy oil,crude oil transporting pump,main machine lubricating pump.
5、Food industry:Using as transporting pump which can transport alcohol,honey,syryp,juide,fixde oil,milk,slurry oil.
Structure characteristics
This kind of pump adotp double-suction structure , both ends of screw are in the same pressure cavity,axial force an be balanced automatically.The bearing of both ends adopt external installing,an being lubricated a lone by using lubricate,so it won't be influenced bu the medium.A couple of synchronous gears are uwed to drive the screws,so the screws surface can't touch at all,an there is a tiny chearance between the two screws. the impurity in the meditm can not fray the screws surface directly(escept scour) .
Except some less discharge ppumps (below the 2w.w 4.0),generally,internal safety valve will be installed on the pump body,when the discharge pressure is over the rated value,it will have certain protection function.There are two entrance-exit directions ,one is horizontally enter and horizontally exit;the other is horizontally enter and vertically upwards exit; the user can choose according to thir own demands.

Application
It applies to deliver clean and non-corrosive medium which has lubricating troperty at temperature beow ≤150℃、with the viscosity of 5-760cSt,The pump's working pressure range from 0.6MPa to 2.5MPa and flow capacity range from 0.6-123m3/h. Feature (1)Medium is delivered in axial direction continuously without agitation and pulsation. (2)Small vibration and low noise (3)High pressure and high efficiency (4)Simple structure,easy disassembly and assembly (5)Small volume and lighe weight (6)Slight wear and long life of the pump Structure:The pumps are sealed generally by mechanical seal and driven by the motor through the claw coupling.
