Twin screw pump Efficiency scope
one The maximum pressure four.0MPa
2 Ability variety one~1000m3/h
three Temperature selection -twenty~120º C
four Thee ciscosity of the medium one~3000mm2/s, when decrease the pace 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 implies the discharge below the particular ciscosity situation, in buy to make certain the pump to operate on the higher performance functioning issue, wehn the test is not ample, we recommend to pick the velocity of the fotation according to the pursuing viscosity.
The viscosity of the mediumcSt Pace r/min
<400 1500
four hundred ~1200 1000
1200~3600 750
When the viscosity of the medium is increased, the customer should make contact with with the company for the speed of rotation and motor electricity.
Software example
1 Oil field: Utilised as the multiphase mixed transporting pump and crude oil transporting pump and the like which can transport oil, gas, water, small strong particullate.
two shipbuilding: Using as maritime loading pump, ballast pump an sewage treatment method pump, principal machine lubricating pump and gasoline oil pump.
three CZPT market: Making use of as loading and transporting pump which can transportation all kinds of resin, pigment, paraffinwax, paint, rinting ink, emulsoid, all kinds of oil crude oil, hesvy oil and the like.
4 Energy plant: Employing as large oil, crude oil transporting pump, main machine lubricating pump.
5 Food sector: Making use of as transporting pump which can transport liquor, honey, syryp, juide, fixde oil, milk, slurry oil.
Construction characteristics
This variety of pump adotp double-suction construction, each ends of screw are in the very same strain cavity, axial pressure an be balanced instantly. The bearing of both finishes adopt external installing, an becoming lubricated a lone by using lubricate, so it is not going to be affected bu the medium. A pair of synchronous gears are uwed to push the screws, so the screws surface can’t touch at all, an there is a very small chearance between the two screws. The impurity in the meditm can not fray the screws surface area straight(escept scour).
Except some significantly less discharge ppumps (under the 2w. W four.), usually, inside safety valve will be set up on the pump physique, when the discharge force is more than the rated value, it will have certain safety operate. There are two entrance-exit instructions, one particular is horizontally enter and horizontally exit The other is horizontally enter and vertically upwards exit The person can pick according to thir own needs.
CZPTal steel
II: Mainly adopting the martensitic corrosion resisting steel
III: Mostly adopting the austenite corrosion resisting steel
