Description

Technical Field

[0001] The invention relates to the technical field of hydraulic pumps and motors, and in particular to an integrated vane motor pump based on electromagnetic drive. Background Art

[0002] When the rotor of the vane pump rotates, the blades are pressed against the inner surface of the stator by the centrifugal force and the pressure oil. In this way, the working volume formed by the two blades, the rotor and the inner surface of the stator absorbs oil from small to large and then discharges oil from large to small. When the blades rotate one circle, they complete one oil absorption and discharge.

[0003] The hydraulic motor pump is based on combining the key moving parts in the electric motor and the hydraulic pump into one, changing the traditional mode of the hydraulic power unit consisting of an independent electric motor, a coupling and an independent hydraulic pump, integrating the hydraulic pump and the electric motor in one housing, eliminating the cooling fan, and forming a new type of integrated hydraulic power unit - the hydraulic motor pump.

[0004] The hydraulic motor vane pump directly converts electrical energy into hydraulic energy output. The motor stator is equipped with motor windings, and the motor rotor is inlaid with permanent magnets. At the same time, as the vane pump rotor moves, low-pressure oil enters the hydraulic motor vane pump from the oil inlet, passes through the flow channel in the special motor housing and the air gap between the stator and rotor, and pressurizes the low-pressure oil to the oil hole at the bottom of the pump core seat, and then enters the oil suction window of the vane pump. After compression in the working chamber of the vane pump, the high-pressure oil is discharged from the oil outlet. The oil forms a circulating oil flow inside the hydraulic motor pump to cool the heat of the motor pump. The motor pump has no external shaft to eliminate the possibility of leakage. The hydraulic power unit composed of the hydraulic motor vane pump without a separate auxiliary pump is small in size. Therefore, the hydraulic motor vane pump has the advantages of quietness, compact structure, high efficiency, convenient cooling, no external leakage and good processability. It can be widely used in hydraulic systems as a power unit and is also suitable for the transportation of media that do not allow leakage. Summary of the invention

[0059] The following is a further description of an integrated vane motor pump based on electromagnetic drive according to the present invention in combination with an embodiment:

[0060] The electromagnetically driven integrated vane motor pump of the present invention can be used not only as a water pump or oil pump, but also as a positive pressure air pump or vacuum pump, making it a multi-purpose motor pump. The overall design of the present invention adopts a tight fit, which is not easy to separate during the production process, which is conducive to improving production efficiency. Except for the structure that acts as the stator and needs to generate electromagnetic force, the rest of the structure is made of stainless steel or brass and other materials that do not conduct magnetism, which ensures the smoothness and reliability of the movement and effectively guarantees the qualified rate.

[0061] The specific working process of the permanent magnet vane motor pump is as follows:

[0062] First, the stator coils of the front oil distribution plate 4, the rear oil distribution plate 8 and the first stator 7 are respectively connected to the externally controlled three-phase symmetrical alternating current from the front oil distribution plate wiring hole 13 on the front pump body 2 and the rear oil distribution plate wiring hole 24 on the rear pump body 11 of the permanent magnet vane motor pump, so that the front oil distribution plate coil 17 and the rear oil distribution plate coil 21 respectively generate a uniform magnetic field consisting of alternating N poles and S poles. The front oil distribution plate coil 17 and the rear oil distribution plate coil 21 just generate a complete circular uniform magnetic field. At the same time, the stator coil generates the same complete magnetic field with uniform alternation of N poles and S poles.

[0063] Then, under the action of the uniform magnetic field on both sides and the outer ring of the first rotor 5, the permanent magnets 19 with staggered N poles and S poles are excited by the electromagnetic field and rotate.

[0064] Finally, based on the principle that the N pole and the S pole repel each other but attract each other, by actively changing the direction of the three-phase symmetrical alternating current, each energized coil can generate a controllable alternating magnetic field, thereby acting on the permanent magnets 19 circumferentially staggeredly inlaid on the first rotor 5 to drive the first rotor 5 to rotate under magnetic drive, and at the same time drive the first blade 6 to achieve telescopic action between the blade slot 18 and the elliptical inner circle of the first stator 7. At this time, air pressure difference is caused at the front pump body oil hole 14, the front oil distribution plate oil hole 15, the rear oil distribution plate oil hole 20 and the rear pump body oil hole 23, thereby achieving the action of sucking and discharging oil.

[0065] The specific working process of the electromagnetic vane motor pump is as follows:

[0066] First, the left pump body wiring hole 37 on the left pump body 26 of the electromagnetic vane motor pump and the right pump body wiring hole 50 on the right pump body 35 respectively lead out the left oil distribution plate coil 39, the right oil distribution plate coil 44 and the rotor coil 41 and connect them to the externally controlled three-phase symmetrical alternating current, and the rotor coil 41 is connected to the external power supply through the inner slip ring 30 and the outer slip ring 34 via the support shaft wiring hole 48, thereby making the left oil distribution plate coil 39 and the right oil distribution plate coil 44 respectively generate a complete cycle of uniform rotating magnetic field consisting of alternating N-level and S-level.

[0067] The rotation speed of the rotating magnetic field is controlled by changing the three-phase symmetrical alternating current. The alternating current connected to the rotor coil 41 on the second rotor 29 has the same wiring principle as the left oil distribution plate coil 39 and the right oil distribution plate coil 44, but is always slightly behind the rotating magnetic field generated by the left oil distribution plate coil 39 and the right oil distribution plate coil 44.

[0068] At this time, the rotating magnetic field of the second rotor 29 is continuously cut by the rotating magnetic fields generated by the left oil distribution plate coil 39 and the right oil distribution plate coil 44, and the rotor coil 41 is axially symmetrically distributed, and forms a mutually cutting relationship with the rotating magnetic fields of the left oil distribution plate coil 39 and the right oil distribution plate coil 44. Thus, an electromagnetic torque is generated under the drive of the electromagnetic force, driving the second rotor 29 to rotate along the direction of the rotating magnetic fields on the left oil distribution plate 27 and the right oil distribution plate 32.

[0069] Secondly, the rotor coil 41 of the second rotor 29 is wound around and fixed to the inner ring by the rotor polyethylene filling layer 42, directly connected to the outer slip ring 34 of the inner ring, and directly in contact with the inner slip ring 30 on the second support shaft 33 that is connected to the power supply. Through continuous sliding contact, brushes are formed to continuously supply power to the rotor coil 41.

[0070] Finally, when the second rotor 29 rotates, the second blade 28 inside it is driven to realize telescopic action in the blade slot 18 and the elliptical inner circle of the second stator 31. At this time, the oil holes of the left oil distribution plate 27 and the right oil distribution plate 32 connected thereto produce a pressure difference, which pushes the hydraulic oil from high pressure to low pressure. When the power is continuously supplied, the second rotor 29 can rotate continuously, thereby relying on electromagnetic force to complete the oil suction and oil discharge action of the vane pump.

[0071] The embodiments described above are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
