Electronic intelligent controller, control method and air compressor applying controller

Abstract

The invention relates to an electronic intelligent controller, a control method and an air compressor applying the controller, and the electronic intelligent controller, comprise a seamless tracking operational amplifier, a control module and a comprehensive executive module which sequentially carry out signal transmission. The invention has the beneficial effects that: as an oil temperature sensor and an environment temperature sensor are additionally arranged on the air compressor, according to the real-time lubricating oil temperature and the environment temperature which are probed by the temperature sensors, the starting and stopping can be automatically controlled, the lubricating oil temperature can be guaranteed to be always higher to dew point temperature, the lubricating oil emulsification phenomenon which can be generated in the prior art can be eliminated, and simultaneously, the phenomenon that in order to improve the operating temperature of the air compressor, the air compressor continuously idles can be reduced; the service life of the air compressor can be prolonged, the unnecessary energy consumption and the maintenance cost of a user on the air compressor can be reduced, and the installation is convenient and reliable; and an overflowing valve is arranged on an exhaust port, and the overflowing valve is connected with a muffler, so that the noise of the air compressor can be reduced.

Description

technical field [0001] The present invention relates to an electronic intelligent controller, a control method and an air compressor using the controller, in particular to an electronic intelligent controller, a control method and an electronic intelligent controller in the fields of oil-injected vane air compressors and oil-injected screw air compressors. Air compressors using this controller. Background technique [0002] Oil-injected air compressors are usually only suitable for working conditions with minimum operating rate requirements. There is only a temperature control valve to control the circulation and cooling of lubricating oil inside, and no temperature sensor to control the minimum temperature is installed on the machine. Its disadvantage is that under extreme weather conditions such as high temperature and high humidity or vehicle-mounted (vehicle-mounted conditions usually do not meet the minimum operating rate requirements), the dew point temperature will...

[0002] Oil-injected air compressors are usually only suitable for working conditions with minimum operating rate requirements. There is only a temperature control valve to control the circulation and cooling of lubricating oil inside, and no temperature sensor to control the minimum temperature is installed on the machine. Its disadvantage is that under extreme weather conditions such as high temperature and high humidity or vehicle-mounted (vehicle-mounted conditions usually do not meet the minimum operating rate requirements), the dew point temperature will be higher than the exhaust temperature, and the moisture in the oil and gas will condense into the lubricating oil In this state, the emulsification of the lubricating oil will deteriorate the lubrication and sealing conditions of the compressor. Continued use in this state will seriously affect the service life of the air compressor, and cause the phenomenon of lubricating oil overflow, which will eventually damage the air compressor and bring unnecessary damage to the user.
