The invention discloses a two-stage speed increasing vortex pump device based on a planetary gear train. The vortex pump device comprises a driving shaft, a driven shaft, a primary vortex pump, a secondary vortex pump and a planetary gear device. The driving shaft is driven by a motor to rotate at a low speed, so that a primary impeller is driven to rotate, meanwhile, a ring gear and a planet carrier are driven to rotate, and the ring gear and the planet carrier form an integral whole through casting and turning technologies. A sun gear is connected with the driven shaft and engaged with the outer portion of a planetary gear, and the planetary gear is engaged with the interior of the ring gear. Through the action of the planetary gear train, the rotational speed of the sun gear is changed,thus, the driven shaft is rotated at a high speed, and meanwhile, a secondary impeller is driven to rotate at a high speed. One end of a connecting pipe is connected with a water outlet of the primary vortex pump, and the other end of the connecting pipe is connected with a water inlet of the secondary vortex pump. Low-pressure fluid flows in through a water inlet of the primary vortex pump, flows out through the water outlet of the primary vortex pump under the action of the primary impeller and becomes high-pressure fluid. The application range of the speed increasing vortex pump is enlarged.
Description
technical field [0001] The invention relates to a speed-increasing vortex pump device based on a planetary gear train, specifically a vortex pump device capable of achieving two-stage speed-up. Through the action of the planetary gear system, the rotational speed of the driven shaft is changed, thereby increasing the rotational speed of the secondary impeller to achieve the effect of two-stage speed-up. Background technique [0002] With the development and application of the pump, the outlet pressure of the impeller cannot meet the pressure requirements in some areas, so increasing the outlet pressure of the pump needs continuous improvement. However, the current vortex pump device can only realize the transformation of fluid from low pressure flow rate to high pressure flow rate. When higher fluid velocities are required, current scroll pumps are not capable of optimum performance. Contents of the invention [0003] Aiming at the above problems, the present invention p...
