On the base of deeply researching overseas advance technique, according to the present-day practical demands of gas-oil mixed transporting, 2W. WH*-type out board bearing double suction dual screw multiphase mixed transporting pump and 2W. W series double screw pump are researched and developed by our company, then we follow the regulations of the national standard GB*******9 and produced it. Through engagement together between driving screw and driven screw and the match between screw and pump body hole, and then form many sealing empty cavities, when the screw is rotational, these sealing empty cavities move ahead continually, push the liquid in the sealing cavity to the exit and then discharged, so the purpose of transporting the liquid can be realized. The advantage oftwo Spindle 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 multi-phase mixed transporting, the gas content can not over *0%, and the sand content can not over **0G/M³ .
3. Outboard bearing structure which adopt independently lubricate, so all kinds of non-lubricate medium can be transported.
4. It adopts synchronous gear driving, between the two rotors 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.**- 0.2 mm)
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~***0m3/h 3. Temperature range **0~**0ºC 4. Thee Viscosity of the medium 1~***0mm2/s, when lower the speed of the rotation it can be up to **6mm2/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 rotation according to the following viscosity. This kind of pump adopt double-suction structure, both ends of screw are in the same pressure cavity, axial force can 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 by the medium. A couple of synchronous gears are used to drive the screws, so the screws surface can't touch at all, an there is a tiny clearance between the two screws. The impurity in the medium can not fray the screws surface directly (except scour). Except some less discharge pumps (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.
