Description
Technical field
A kind of high viscous many impurity fluid media (medium) conveying Double helix ellipse sealed engagement pair, belongs to screw pump Meshing Pair technology
Field.
Background technology
In recent years, with the continuous reduction of landing field fossil resource reserves, exploitation and the transport of Marine oil and gas resource obtain
Development rapidly, but the marine environmental pollution problem that offshore oil and gas field exploitation brings is more and more prominent, extensive oil spill accident
The probability occurred is the most increasing.Marine oil overflow is recycled fast and effectively, for the marine eco-environment protection and
Human survival safety it is critical that.On the other hand, in petrochemical production process, substantial amounts of oily sludge garbage is not
Pregnancy ceased is given birth to and piles up, and needs periodic cleaning.But owing to this part marine oil overflow and oily sludge may be mingled with animal
The solid impurity such as corpse, house refuse so that traditional fluid pumping apparatus exists medium viscosity bad adaptability due to it, easily
The shortcomings such as abrasion, are not the most well positioned to meet the requirement of marine sump oil conveying.
In order to realize the pump function of impure more high viscosity oil sludge, it is currently suggested two kinds of different screw pumps
By Meshing Pair: Meshing Pair that band tooth seal disc coordinates with screw rotor and the Meshing Pair that eccentric disc coordinates with screw rotor.Its
In existing document (patent No.: WO 82/03428) propose the Meshing Pair that a kind of band tooth seal disc coordinates with screw rotor, it is close
With multiple sealing teeth on envelope disk, in screw pump work process, sealing on disk is relied on to offer on tooth and screw rotor
Helicla flute cooperation realizes gear motion, and cooperatively forms periodically variable working chamber volume with casing, it is achieved high viscosity medium
Conveying.But the sealed disc of this band toothing limits the flow of single-screw (single screw) pump, also results in seal disc tooth and screw rotor
The friction and wear of groove side.
In order to improve flow and reduce abrasion, existing document (patent No.: WO 91/14869, US005395225A,
EP0523113B1) Meshing Pair that a kind of eccentric sealed disk coordinates is proposed with screw rotor, in screw pump work process, close
Form uniform wear between closing disk and screw rotor, extend service life.In order to improve the conveying capacity of screw pump further, existing
Have in document (patent No.: WO 00/05503, US006447275B1, EP1097305B1) and propose eccentric disc is turned with screw rod
The Meshing Pair that son coordinates has carried out structure improvement, shortens screw rotor entrance to the distance between compression section.But it is this
The Meshing Pair that eccentric disc coordinates with screw rotor in whole pump housing work process, only part seal disc and screw rotor
Mesh regional is the working region of pumping fluid, and another part mesh regional is backhaul district, causes the utilization rate of screw rotor
Relatively low.And this engagement feature makes two seal discs can not be driven by screw rotor rotates, close to meet periodic movement
System, needs additional auxiliary connecting device between two seal discs, cause screw rod pump structure complicated, bulky, heavy, to containing
The adaptability of many impurity medium is poor, and the existence of auxiliary connecting device also makes screw pump reliability of operation and efficiency significantly drop
Low.
Summary of the invention
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that one can carry high viscous, many
Impurity fluid media (medium), discharge capacity is big, and the height of simple in construction glues many impurity fluid media (medium) conveying Double helix ellipse sealed engagement pair.
The technical solution adopted for the present invention to solve the technical problems is: this kind high viscous many impurity fluid media (medium) conveying is with double
Spiral ellipse sealed engagement pair, including screw rotor and casing, screw rotor is arranged in casing, it is characterised in that: described
