Description

Technical Field

[0001] The invention relates to the technical field of pump production, in particular to a circumferential line coupled planetary synchronous rotary piston pump. Background Art

[0002] The rotary pump is a relatively important pump among various pumps, including Roots pumps, vane pumps, disc rotor pumps, gear pumps, yin-yang rotor screw pumps, etc. However, these pumps will have some wear, so their lifespan cannot be guaranteed. Although the blades of Roots pumps, disc rotor pumps, gear pumps, and yin-yang rotor screw pumps will not wear, both rotors participate in the compression of the fluid. The two rotors compress the fluid simultaneously or alternately, so the synchronous gear load is large and the gears will have greater wear. The Roots pump is the most obvious, and the overhaul time is generally only 2000 hours. The blades of the vane pump are pressed against the pump body under the action of centrifugal force and will also wear. At the same time, the processing of these pumps is relatively complicated, and some even require 5-axis machine tools, and the production cost is too high. The technical solution aims to propose a rotor pump with very little or no wear, which is easy to process and has low cost. The pump rotor only needs a forming milling cutter to be processed. A rotary piston rotor pump with circular line meshing is used. In the circular line meshing state, the auxiliary rotor does not do work on the fluid, so there is basically no dynamic load on the auxiliary rotor. The synchronous gear only wears when the concave and convex parts are coupled. At the same time, a planetary synchronous gear assembly is used to evenly distribute the wear to each gear, thereby greatly improving the life of the rotor pump. In the time when the rotor rotates one circle, the time when the blades and grooves are coupled only accounts for a small part of the total time of one circle. Most of the time is the circular line coupling state of the main and auxiliary rotors, so the wear of the synchronous gears is very small. Summary of the invention

In the figure, the main rotor blade and the groove of sub-rotor A are in a coupled state. At this time, the synchronous gear has a small amount of wear. A main rotor, a sub-rotor, two main rotor blades and a planetary synchronous gear assembly are fixed to form a closed space as shown in the figure. Figure 5 and Figure 6 .

[0009] Furthermore, the planetary synchronous gear assembly is a structure in which the sun gear is fixed and the planet carrier is meshing. The outer rings of the planetary gears are respectively connected to the main shafts of the corresponding rotors. The main rotor rotates counterclockwise. The main rotor and the auxiliary rotor A and the auxiliary rotor B are synchronized with each other under the joint action of the auxiliary rotor A synchronous gear, the main rotor synchronous gear, the auxiliary rotor B, the auxiliary rotor B synchronous gear and the connected planetary gears. The main rotor blades and the auxiliary rotor A grooves and the auxiliary rotor B grooves are in a coupled state. The main rotor, the auxiliary rotor A and the pump body, the front cover plate and the rear cover plate together form a closed space A. The main rotor, the auxiliary rotor B and the pump body, the front cover plate and the rear cover plate together form a closed space B.

Liquid or gas is compressed multiple times to realize multi-stage compression and obtain higher pressure. Four main rotors, four sub-rotors, two main rotor blades and planetary synchronous gear assembly are fixed to form as shown below. Fig. 9 , Fig.10 and Fig.11 .

[0011] Furthermore, the auxiliary rotors A and B are symmetrically installed around the main rotor, and have two inlets and two outlets respectively.

[0016] 2. The device of the invention compresses liquid or gas by setting the blades to act as pistons, and the grooves are only coupled to the blades under the action of the planetary synchronous gear assembly, so that the main and auxiliary rotors do not interfere with each other in movement.

[0017] 3. The device of the invention has very little wear by setting up a planetary synchronous gear assembly. The planetary wheels of the planetary gears keep moving, so that the position of the planetary gear meshing with the outer gear ring is not fixed each time the main and auxiliary rotors are coupled, so that the position of wear is also not fixed, so that the wear is evenly distributed to the entire gear assembly. The planetary synchronous gear assembly has very little wear on the whole. In the non-coupled state, the main rotor and the auxiliary rotor are in circumferential contact, the circumferential force of the auxiliary rotor is zero, and the load of the synchronous gear assembly is zero, so no wear occurs and the service life is long.

All main rotors 3 share a main shaft, all auxiliary rotors A2 share a main shaft, and each set of main and auxiliary rotors is separated by a partition.
