Small quick compressor based on electromagnetic control

Abstract

The invention discloses a small quick compressor based on electromagnetic control. The small quick compressor is mainly composed of a main combustion chamber system, a power system and an electromagnetic control circuit. The main combustion chamber system is composed of a gland and two layers of sleeves. Heat conduction oil flows through a gap between the two sleeves to heat a combustion chamber.The power system comprises a cylinder body, a power cylinder gland, a braking circular ring, a power piston, a driving circular ring and a laser distance measuring sensor. The laser distance measuringsensor measures the distance through a center hole of the power cylinder gland, and therefore, control of the compression process is achieved. The electromagnetic control circuit comprises a direct-current power supply, a slide rheostat and five switches, wherein the direct-current power supply supplies current; the slide rheostat is used for adjusting the circuit current so as to change the electromagnetic force between the coils; three switches are used as on-off switches of a circuit, and the other two switches are jointly used as change-over switches and are responsible for changing the current flow direction in the coil, so that the direction of electromagnetic force is changed. The quick compressor is simpler and more compact in structure, and the working process is more efficient.

Description

technical field [0001] The invention is a small fast compressor based on electromagnetic control, which relates to the technical field of thermal energy and power engineering testing, in particular to a fast compression experiment for the study of the spontaneous combustion characteristics of hydrocarbon fuels such as gasoline, diesel and aviation kerosene and the combustion process of internal combustion engines device. Background technique [0002] The fast compressor is a basic experimental platform for simulating the working process of internal combustion engines and the spontaneous combustion characteristics of gasoline, diesel, aviation kerosene and other hydrocarbon fuels. The fast compressor pushes the compression piston with the help of external force to instantly compress the pre-mixed gas in the combustion chamber to a thermodynamic state of high temperature and high pressure, and then uses the braking system to stop the compression piston, so that the pre-mixed g...
