Applications:
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.
¡ô 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 self-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 adopt independently lubricate, so all kinds of no lubricate medium can be transported.
4. Marine pump adopts synchronous gear driving, between the two tutors there is no touch at all, even 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 medium 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.
¡ô Performance scope
1. The highest pressure 4.0MPa
2. Capacity range 1¡«1000m3/h
3. Temperature range -20¡«120¡æ
4. Thee viscosity 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 influence the twin screw pump, the nominal discharge of the pump means the discharge under the certain viscosity condition, in order to ensure the pump to work on the high efficiency working condition, when the test is not enough, we suggest to select the speed of the flotation according to the following viscosity.
The viscosity of the medium cSt Speed r/min
£¼400 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.
