A cooling mechanism for an air compressor and a control method thereof

Abstract

The invention discloses a heat dissipation mechanism for an air compressor and a control method thereof, aiming to provide a heat dissipation mechanism with two-way heat dissipation inside the motor and the casing and with effective control of the state of the impeller. The main point of the technical solution is to install the cylinder There is a motor protection system for protecting the motor, and the motor protection system is set to include a controller for controlling the start and stop of the motor, an angle detection unit, a speed detection unit, a motor current detection unit, an angle and speed detection unit, a motor The current detection unit is electrically connected with the controller respectively. Through the set controller, the angle detection, speed and motor current detection are used to detect the state of the motor, and have real-time and accurate monitoring effects on the fan. For example, when there is a headwind state When the load current of the motor increases and the speed decreases, the normal operation of the fan can be maintained by increasing the current. The present invention is applicable to the technical field of air compressor equipment.

Description

technical field [0001] The invention relates to the technical field of air compressor equipment, more specifically, it relates to a heat dissipation mechanism for an air compressor and a control method thereof. Background technique [0002] Air compressors are air compressors, which are the basic products of industrial modernization. It is a device that converts the mechanical energy of the motor into gas pressure energy, and is a device that generates air pressure for compressed air. The air compressor is a miniature reciprocating piston compressor. Its working principle is: when the motor uniaxially drives the crankshaft of the compressor to rotate, through the transmission of the connecting rod, the piston with self-lubrication without adding any lubricant will reciprocate. The working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically. With the increasing diversity of market demand, in order to ...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the air compressor, the rotor and stator in the motor will generate a large amount of heat energy, and the heat released is mainly concentrated in the inside of the motor of the air compressor and the surface of the air compressor shell. The heat dissipation mechanism is used to effectively dissipate heat from the above parts. Therefore, it is necessary to effectively dissipate heat from the inside of the motor and the surface of the shell of the air compressor. If a large fan is used, it will occupy a large volume, and it will also be due to the existence of " The phenomenon of "eating wind", especially in the case of headwind, will affect the heat dissipation of the motor even more, so it is necessary to improve the effective control of the fan
