Abstract

The invention relates to a self-lubricating vacuum pressure compound air pump, which belongs to the technical field of air compressing or delivering machinery for vacuumizing air and outputting compressed air synchronously. The self-lubricating vacuum pressure compound air pump consists of a motor and a pump head, wherein the inside of the pump head is provided with a pump body; a cooling fan is arranged on the pump body near the motor; and a cooling part is arranged at the periphery of the cooling fan of the pump head; a fairing is arranged between the pump body and an outer cover; a bracket is fixed at the bottom of the air pump; the front end of the pump body is provided with a front end cover; the back end of the pump body is provided with a back end cover; a front bearing block is arranged on the front end cover; a back bearing block is arranged on the back end cover; a front bearing is arranged on the front bearing block; a back bearing is arranged on the back bearing block; and a rotating shaft penetrates the front bearing and the back bearing. The self-lubricating vacuum pressure compound air pump solves the problems of slow cooling of the compressed air, unadjustable working plane and easy generation of air turbulence in the prior air pumps.

Description

technical field [0001] The invention relates to the mechanical technical field of simultaneously evacuating air and outputting compressed air for compressing or transporting air, in particular to a self-lubricating vacuum pressure composite air pump. Background technique [0002] Most of the existing air pumps used in conjunction with printing machines are ZYB vacuum pressure composite air pumps. Since this type of air pump rotates at high speed during operation, friction occurs when the sliding vane slides radially in the rotor groove, which generates a large amount of heat. The temperature between the sliding vane and the rotor will soon rise to over 400°C. The overheating of the sliding vane and the rotor will cause the rotor and the sliding vane to be damaged at the same time, and even the motor will be burned. In order to ensure the normal operation of the air pump, an oil lubrication device and cooling are used. However, when the air pump works for a long time, due to ...
