Automatic control air compressor loading system

Abstract

The invention discloses an automatic control air compressor loading system which comprises a cooling water tank and a cooling pipe arranged in the cooling water tank. An air inlet of the cooling pipe is connected with the air compressor, and an air outlet is connected with loading equipment; the control equipment controls the loading pressure and the loading time of the loading equipment; the loading equipment comprises a pressure relief opening and a buffer tank; an air outlet of the cooling pipe is communicated with the pressure relief opening and the buffer tank through an air outlet pipeline; a loading electromagnetic valve for controlling the opening and closing of the pressure relief opening is arranged at the pressure relief opening; a pressure sensor is arranged on the air outlet pipeline; the backpressure electromagnetic valve is communicated with the side wall of the buffer tank through a pipeline; and the loading electromagnetic valve, the pressure sensor and the backpressure electromagnetic valve are electrically connected with control equipment. According to the invention, the volume is small, the temperature of cooled compressed air is about 50 DEG C, so that a test control system can work stably and reliably for a long time, and meanwhile, the backpressure control mode can be adjusted, so that the loading pressure test requirements of multi-model engine air compressors of 8bar, 10bar, 12.5 bar and the like can be met.

AI Technical Summary

Problems solved by technology

However, the above-mentioned air compressor loading device does not perform special cooling on the air compressor outlet pipeline, which will damage the control valves and sensors in the device in the long-term high-temperature and high-pressure working environment, and the service life of the device will be short.

[0006] The above-mentioned air compressor loading device uses a manual pressure regulating valve to control the loading pressure. When different models require different loading pressures and different engine speeds, the loading pressure cannot be stably controlled.

[0007] The existing air compressor loading device does not have an independent control system, and the loading time and pressure cannot be conveniently set according to different test requirements, and the dynamic curve and display alarm of temperature and pressure cannot be performed.
