Abstract

The invention discloses a high-efficiency screw composite oil conveying pump. The high-efficiency screw composite oil conveying pump comprises a pump body (1), a pump cover (2), a stator (3), a screw composite left rotor (4), a screw composite right rotor (5), a two-direction pressure isolation device (6), a flow distribution plate (7), a bearing pedestal, a main shaft, and a mechanical seal. When the pump rotates, the screw composite left rotor (4) and the screw composite right rotor (5) are driven by the main shaft to move relative to each other, the rotor spiral surfaces of the left and right rotor push the two-direction pressure isolation device so as to form a high-pressure area and a low-pressure area, oil in the low-pressure area is absorbed, and the oil in the high-pressure area is pumped out, and reciprocating motion is performed so as to finish absorbing and discharging oil. The screw composite rotors are variations of single-lead screws, the stator is made of an alloy steel piece, and clearance fit is adopted in oil conveying and discharging processes; when the oil is pumped, good medium passing performance is achieved, and the oil contains sand, air and water; the pump is durable, efficient and energy-saving, and works stably; and noise is low.

Description

Efficient screw rod combined type oil transfer pump
Technical field
The efficient screw rod combined type of the present invention oil transfer pump belongs to the technical field of pump machines.
Background technique
Existing screw pump is that a long bolt is realized medium transport with the stator gum cover extruding of combining closely; This pump adapts to the clean product oil of delivery ratio; Be not suitable for carrying thickness, contain sand, gassiness, oil that water content is big, this pump gum cover stator rapid wear, maintenance cost is high.
Summary of the invention
The present invention is according to the screw pump principle; Adopt the screw rod hybrid rotor, single helical pitch variation of screw rod just is the screw rod hybrid rotor, and the pressure segregating unit that cooperates with it together interacts, to-and-fro motion; And pump housing particular design; Provide a kind of rational in infrastructure, operate steadily, energy-conserving and environment-protective, long service life, maintenance cost are low can carry thin oil, also can carry thickened oil containing sand, realize that Oil, Water, Gas mixes defeated pump.
Embodiment
A kind of efficient screw rod combined type oil transfer pump comprises the pump housing (1), pump cover (2), stator (3), left rotor (4), turn right son (5), bidirection press isolation mounting (6), thrust plate (7), bearing support (8), main shaft (9), mechanical seal (10).It is characterized in that: adopt two screw rod hybrid rotor horizontal symmetrical of brand-new design to install, two stators are alloy steel pieces, and in fed sheet of a media, two screw rod hybrid rotors do not contact with stator; The screw rod hybrid rotor is a single flighted screw, and two work surface of contact of its rotor peripheral face and pressure segregating unit are rolling friction, stud with thrust plate in the middle of two rotors, and two rotor both sides and end cap form two pump work chambeies; Rotor runs to low spot place volume and enlarges, and promptly forms oil sucting cavity, and oil is sucked into, when running to high some place; Volume dwindles, and forms pumping cavity, and oil is discharged from; Two active chamber relative movement, an oil suction, another is exactly oil extraction; When turning round continuously thus, constantly oil suction and oil extraction reached the purpose of pump fed sheet of a media.
The characteristics of the efficient screw rod combined type of the present invention oil transfer pump mainly show:
1, the screw rod hybrid rotor is equivalent to the single flighted screw to-and-fro motion, and medium is good through performance, and the adaptation of fed sheet of a media is wide;
2, stator changes steel part into, does not contact again, and is durable on the one hand, and noise is little on the one hand;
3, pump adopts two screw rod hybrid rotors, relative movement, and a suction one row's centrifugal force is little, and the suction oil connectivity strengthens, and has improved the steady degree of pump operation;
4, pressure segregating unit has the wear automatic-compensation function, has reduced internal leakage, has improved the efficient of pump.
