Detailed Description

The rotor driving part of the vibration reduction type magnetic sliding vane pump comprises an inner magnetic rotor 10, an outer magnetic rotor 9 and an isolation sleeve 11 between the two rotors.

As shown in fig. 1, the vibration damping magnetic sliding vane pump includes a pump body 2, a left pump cover 4, a right pump cover 14, an outer wear plate 3, a driving side wear plate 13, and a rotor assembly 1. The left pump cover 4 and the right pump cover 14 are respectively assembled and fixed at two ends of the pump body 2 to form a closed pump shell of the magnetic sliding vane pump; the two wear-resistant plates are respectively positioned on the inner sides of the left pump cover 4 and the right pump cover 14 and are used for sealing and fixedly assembling two ports of the pump body 2 to form a sealed pump cavity 12 for pumping operation of the rotor. The rotor shaft 15 in the rotor assembly 1 penetrates through the pump cavity 12 and is horizontally and rotatably supported by the sliding bearing assembly 7 of the left pump cover 4 and the sliding bearing assembly 17 of the right pump cover 14, and the driving shaft end of the rotor shaft is assembled with a rotor driving part to drive the blade rotor part to pump media in the pump cavity 12 so as to continuously pump liquid media out of the pump outlet 22.

In the structure, as shown in fig. 2, the outer wear plate 3 is provided with a balance through hole 20, the balance through hole 20 is preferably provided on the plate body of the booster pump cavity area a close to the pump outlet 22 side, and in order to reduce the influence of the balance through hole 20 on the pump efficiency to the maximum extent, the hole diameter of the through hole should not be larger than 8mm, preferably 4-8 mm. During the operation of the pump, a part of a medium is filled into an installation gap between the outer wear plate 3 and the left pump cover 4 through the balance through hole 20 under the action of the pump pressure, so that the sliding bearing assembly 7 is cooled, the lubrication on the sliding bearing assembly 7 is enhanced, the operation performance of the rotor assembly 1 is improved, more importantly, a reaction force for counteracting the vibration axial force of the rotor shaft on the sliding bearing assembly 7 is generated, the vibration generated by the play of the rotor assembly 1 in one direction during the operation of the pump is eliminated, and the vibration friction damage to the wear-resistant ring is avoided.

In this embodiment, the thrust ring assembly 5 is assembled on the rotor shaft 15 at the outer end face of the sliding bearing assembly 7 at the outer end side of the rotor shaft, and is matched with the end face of the sliding bearing assembly 7 to prevent and offset the axial movement of the rotor assembly 1 to the driving side during operation, and is combined with the balance through hole 20 of the outer wear plate 3, so as to avoid the wear of the wear plate caused by unbalanced axial force, further improve the vibration reduction and noise reduction effects of the pump operation, and enable the pumping operation to be stable and smooth for a long time.

In this embodiment, the balance through hole 20 structure of the outer wear plate can also participate in the bearing lubrication cooling loop, and the two structures are combined to achieve better lubrication cooling effect while eliminating the running vibration of the pump. As shown in fig. 2, the bearing lubrication cooling circuit is formed by communicating a cooling circulation tank 30 which is arranged outside the pump outlet 22 and communicated with an internal circulation channel 8 in the pump cover communicated with the pump inlet 21 through a pipeline, wherein the internal circulation channel 8 is a channel which surrounds the sliding bearing assembly 7/17 in the pump cover and is communicated with the sliding bearing assembly 7/17, the upper port of the internal circulation channel 8 is communicated with the pump inlet 21 through a front pipeline 32, and the lower port is communicated with the cooling circulation tank 30 through a rear pipeline 33. The high-pressure medium entering the installation gap between the outer wear plate 4 and the left pump cover 7 through the balance through hole 20 also participates in the backflow of the bearing lubricating and cooling loop, and continuously and circularly lubricates the bearing and the operation high-temperature area of the cooling pump in the pumping process.
