Gear, gasket seal, dowel hole and the bolt hole of gear cavity two sides, driving and driven gear be attached separately to driving shaft and from
On moving axis.Although this miniature ultralow temperature gear pump driven by magnetic force takes the soft transmission of magnetic force, static seal substitution dynamic sealing, causes tooth
All flow passage components of wheel pump are completely in the cryogenic liquid coolant circulation pump of the No leakage pattern of sealing state.But due to knot
Structure is complicated, and manufacturing cost is high.
The content of the invention
The utility model provides a kind of magnetically-actuated Mini gear pump in pipeline, and it is a kind of greatly simplifies
Gear pump, and the problem of thoroughly prevented to outward leakage.
A kind of Mini gear pump of magnetically-actuated in pipeline of the present utility model, including delivery pipe, are arranged on
Outer magnetic driving mechanism on the outside of delivery pipe, it is characterised in that the Mini gear pump with internal magnetic pole is provided with the inner side of delivery pipe,
Described outer magnetic driving mechanism includes being set with delivery pipe, and the rotary shaft being rotatablely connected by belt and motor, is arranged on
Bearing, bearing block, axle sleeve and the bottom plate for being arranged on bearing block bottom on the outside of rotary shaft, outer magnetic pole are arranged on rotary shaft and conveying
Between pipe；
The enclosed type that the described Mini gear pump with internal magnetic pole is adhesively-bonded together to form by front shroud, shell and back shroud
Gear cavity, the driving gear and driven gear being arranged in enclosed type gear cavity body and the internal magnetic pole being embedded on driving gear
Formed, inlet port and oil discharge outlet are respectively equipped with described front shroud and back shroud.
Preferably, described cover plate, shell and back shroud are made of nonmetallic materials.
Preferably, shaft block ring is provided with the junction of described bearing and rotary shaft, in bearing and bearing block junction
Provided with hole back-up ring.
The utility model method of operation is as follows：
Motor rotates rotary shaft by belt transmission, and two installed in rotary shaft magnetic pole is with rotation, band internal magnetic pole
Mini gear pump driving gear, rotated in the presence of outer magnetic pole, so as to drive driven gear to rotate, by liquid from oil suction
Mouth suction, is discharged from oil discharge outlet, completes the normal work of gear pump.
It is of the present utility model significantly to have the beneficial effect that：
1. fundamentally solve gear pump leaks out problem
Because Mini gear pump is arranged in conveyance conduit（That is the magnetic pole of drive gear rotation is arranged on outside pipeline）Even if
There are leakage and leakage in pipeline, it is impossible to leak into outside pipeline, it can be ensured that work-yard and environment be not contaminated, especially
It is when conveying poisonous and harmful liquid, it is ensured that the safety of environment and personnel.
2. simplify the structure of gear pump
Because gear pump of the present utility model is placed in conveyance conduit, two floating gears glue in forward and backward cover plate and shell
In the gear cavity body for closing closing, therefore eliminate gear shaft, bearing, seal, connecting bolt（Fixed forward and backward cover plate and shell）
Deng part, make the structure of gear pump greatly simplified, also simplify the assembling of gear pump, reduce cost, improve production efficiency.
