Description
Technical field
This utility model is related to oil feed pump, more particularly to a kind of immersion hydraulic elevator oil feed pump.
Background technology
Screw pump is to be engaged spatial volume change and movement to convey liquid or be allowed to by what the pump housing and screw rod formed
The drum pump of supercharging, screw pump are divided into single-screw (single screw) pump, Quimby pump and screw pump etc. by screw rod number.Its operation principle is when electricity
When motivation drives pump shaft to rotate, on the one hand screw rod is rotated around the axis of itself, and on the other hand it is rolled along sleeve inner surface again, in
It is the sealed chamber to form pump, its screw rod each rotation, the liquid for sealing intracavity push ahead a pitch, with the company of screw rod
Continuous to rotate, liquid spiral fashion presses to another annular seal space from an annular seal space, finally extrudes the pump housing.Screw pump is used as one kind
The machinery of new conveying liquid, with simple structure, safe and reliable, easy maintenance, to go out liquid continuous uniform etc. excellent
Point, therefore application commercially is widely.
In elevator industry, due to limited space, if not using the screw pump of immersion to there is and cannot meet dress
It is little with space, the requirement of compact in design, meanwhile, if pump is exposed outside, its leakage point is more, can cause the pollution of environment,
Noise is big simultaneously, and space hold is more.
Utility model content
The purpose of this utility model is to provide a kind of immersion hydraulic elevator oil feed pump, solves existing hydraulic elevator because empty
Between it is limited, pollute and exist that noise is big outside by pump exposed, space hold is more, and easily because asking for environment is polluted in leakage
Topic, while this oil feed pump has simple structure, parts are few, reduce the friction of driving shaft, low power consumption and other advantages.
This utility model solves the technical scheme adopted by its technical problem：A kind of immersion hydraulic elevator oil feed pump,
Including the pump housing, the driving screw rod being arranged in the pump housing and driven screw, driving screw rod and driven screw engagement adaptation, driving screw rod
Front end is arranged with the bearing being adapted with the pump housing, and the rear end opening of the pump housing is arranged；Driven screw and driving screw rod are in integrally cylinder
Shape structure；Driven screw includes driven head and from driven head shaft to the driven spire for extending to the right, driven head side
Radially a circle indent forms driven torus v notch v groove；Driving screw rod includes active head and from active head shaft to the right
The right-hand member end of the active spire of extension, active spire and driven spire flushes；Active head side radially one
Circle indent forms the first actively annular gap slot and the second annular gap slot, and first actively annular gap slot and the second annular lack
Molding ring cam set between mouth groove；Driven torus v notch v groove and ring cam set are adapted；Driven head is located at driven torus v notch v
Groove left end portion and the annular gap slot of the first active are adapted；Driven head is located at driven torus v notch v groove right end portion and second
Annular gap slot is adapted.
Preferably, the length of driven spire is longer than the length of active spire, its be longer than active spire part and
Second annular gap slot is adapted.
In order to ensure the cleaning in the pump housing, service life is improved, the rear end end of the pump housing is provided with filter mantle.
Further, driven screw is provided with two, respectively the both sides engagement adaptation with driving screw rod side wall.
The beneficial effects of the utility model：Traditional oil feed pump is compared, because which is immersion, so structure is simpler,
And it is little to take up room using in, can be prevented effectively from pump exposed that and the noise for causing is big outside, space hold is more, because letting out
The problem of dew and pollution environment.Driven torus v notch v groove is set on driven screw, is led by first is arranged in driving screw rod
Rotating ring v notch v groove, the second annular gap slot, ring cam set and driven screw coordinate, and realize the assembling of driven screw, structure letter
It is single, reasonable, compact.
Below with reference to drawings and Examples, this utility model is described in detail.
