Drum type cone air pump and drum impeller processing method

Abstract

The invention relates to a drum type cone air pump and a drum impeller processing method. The drum type cone air pump comprises a pump body, a hub pump cover, a drum impeller and a drive motor; a conehole is arranged inside the pump body; an inner support frame is arranged inside the cone hole; the drum impeller is rotatably assembled between the hub pump cover and the inner support frame; the drum impeller is frustum-shaped; the drum impeller comprises a front hub carrier, a rear hub carrier and a frustum cylinder wall; a plurality of blades are arranged on the frustum cylinder wall; the diameter of the front hub carrier is less than the diameter of the rear hub carrier; the front hub carrier is towards one side of the inner support frame; a first rotating shaft is arranged between the front hub carrier and the inner support frame; one end of the first rotating shaft is fixedly connected with the front hub carrier, and the other end thereof is rotatably assembled with the inner support frame; a second rotating shaft is arranged between the rear hub carrier and the hub pump cover; the first rotating shaft and the second rotating shaft are coaxially arranged; and the drive motor isin transmission connection with the second rotating shaft. The drum type cone air pump provided by the invention avoids the situation that a positive displacement air pump cannot continuously and stably output air flows.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to a drum-type conical air pump and a processing method for a drum impeller. Background technique [0002] Air pump, also known as air pump, is widely used in aeration, sewage treatment, electroplating aeration, biogas tank aeration, tunnel ventilation and other occasions. The current air pumps are mainly positive displacement pumps. The air pumps mainly realize the pumping of fluid by periodically adjusting the volume in the pump cylinder. The hydraulic pumps in daily life are positive displacement pumps. [0003] The current volumetric air pumps have the following problems during use: ① In order to improve the efficiency, the pump chamber needs to have better sealing, which makes the manufacturing cost of the air pump higher; There is a large friction between the piston and the pump chamber, which on the one hand reduces the working efficiency of the air pump, and on the other ...
