Embodiment Construction

[0016] In order to illustrate the technical solutions of the present invention more clearly, a brief introduction will be made below in conjunction with the drawings and embodiments. Obviously, the drawings in the following description only relate to some embodiments of the present invention, and do not limit the present invention.

[0017] see figure 1 As shown, the method for preventing lubricating oil emulsification of an electric air compressor with oil for automobiles of the present invention comprises the following steps: the air compressor temperature sensor in the S1 electric air compressor detects the temperature in the electric air compressor body and feeds back to the control At this time, the electric air compressor temperature value is the first air compressor temperature value; the controller compares the first air compressor temperature value with the preset high temperature protection value, and the preset high temperature protection value can be set to 110°C; ...

Abstract

The invention discloses a method for preventing emulsification of lubricating oil of an oiled electric air compressor for an automobile. The method is combined with the character of the electric air compressor, running of the electric air compressor is dynamically controlled according to the relative humidity of the environment and the relative humidity in a body of the electric air compressor, and emulsification of the lubricating oil of the electric air compressor is prevented. According to the method, control is easy, cost is low, running reliability is high, and the lubricating oil emulsification preventing capability is high.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for preventing lubricating oil emulsification of an oil-filled electric air compressor for automobiles. Background technique [0002] The current environmental situation is getting worse and worse. In response to national policies, new energy buses are becoming more and more popular. As the product with the highest working efficiency among air compressors, oil-powered electric air compressors are widely used in new energy buses. However, the electric air compressor cannot meet the effective load rate under the condition that the vehicle starts and stops less, resulting in a continuous increase in the failure rate, which seriously affects the service life of the product and driving safety. At present, the load rate of the electric air compressor is increased and the emulsification of the lubricating oil is avoided mainly through regular maintenance, improving th...
