Oil-free vortex air pump

Abstract

The invention discloses an oil-free vortex air pump. The oil-free vortex air pump comprises an outer shell, a motor, a bearing piece connected with the rotating end of the motor, and a compression assembly connected with the bearing piece and arranged in the outer shell, wherein the compression assembly comprises a movable vortex disc connected with the bearing piece, a first vortex disc and a second vortex disc which are arranged on two side surfaces of the movable vortex disc respectively, a first cooling cavity formed in the side surface of the first vortex disc and a second cooling cavityformed in the side surface of the second vortex disc; and the first vortex disc is arranged on the side relatively close to the motor, a first cooler is arranged between the first cooling cavity and the motor, and a second cooler is arranged on the side, relatively away from the motor, of the second cooling cavity. The device is large in air displacement, high in inflation pressure, low in noise,long in service life, free of maintenance, variable in air suction and exhaust positions and suitable for suspension systems of various vehicle types.

Description

technical field [0001] The present disclosure generally relates to the technical field of air pumps, in particular to an oil-free scroll air pump. Background technique [0002] In the manufacture of high-quality automobiles, it is necessary to have both the comfort of a car and the passing performance of an off-road vehicle. Therefore, an air suspension system is usually used, which can judge the height change of the vehicle body according to different situations, and then control the air pump and other devices to make the spring Automatically compress or extend, thereby lowering or raising the chassis to increase the stability of the high-speed body; the air pump is the air pump, a device that removes air from a closed space or adds air from a closed space. The electric scroll air pump is an air pump powered by electricity. The impeller is driven by electricity to rotate. The gas between the impellers will be accelerated along the blades and the radial direction due to the ...

AI Technical Summary

Problems solved by technology

The electric scroll air pump is an air pump powered by electricity. The impeller is driven by electricity to rotate. The gas between the impellers will be accelerated along the blades and the radial direction due to the rotating motion. After the gas enters the outer gas ring, it will return to the blades by the pressure difference. The base of the air ring forms a strong airflow, so that the gas moves in a spiral direction in the air ring to achieve the purpose of pressurization; however, the air pumps used in the prior art usually have short life, high noise, require frequent maintenance, and are not suitable for various types of air pumps. vehicle model defects
