Experimental principle of air compressor performance experimental device
The working process of the compressor can be represented by a dynamometer diagram, which reflects the change of the gas pressure in the cylinder with the volume. The core of this experiment is to use the modern test technology to measure the dynamometer of the actual compressor. In order to obtain the closed dynamometer of the compressor working process, the pressure sensor is used to test the pressure in the cylinder, and the Hall switch is used to determine the piston of the compressor. position. When the experimental system is running normally, the Hall switch generates a pulse signal, and the data acquisition board collects the pressure signal at a predetermined frequency under the excitation of the pulse signal. When the next pulse signal is generated, the computer interrupts the collection of the pressure signal and collects the signal. Data is saved. Obviously, the time interval between the two pulse signals of the proximity switch corresponds to the reciprocating operation of the piston in the cylinder (one cycle), during which the compressor completes the four processes of expansion, suction, compression and exhaust. The signal is amplified and sent to the computer. After calculation, the relevant data in the working process of the compressor and the closed indicator diagram and the expanded indicator diagram are obtained. After the experimental measurement of the compressor power diagram, according to the engineering thermodynamics principle, the process equation of the gas expansion and compression process in the compressor and the power consumption of the compressor can be further determined.
A Great Addition to Outdoor Garden Decoration
The adorable solar statue is weather-proof, rust-resistant, and durable for years of quality use. With its artistic look and intricate details, the outdoor sculpture adds a delicate touch of illuminating beauty at night.
Please Note:
1. Make sure the button is set to the "ON" position and keep charging for 10 hours under the sun at the first using.
2. It may take longer time to full charge if there is no strong light or in Winter. Please do not let it covered by the leaves, flowers or trees, or it can`t absorb solar energy or will light up at daytime.
Effective Solar Panel
During the days the solar panel collects sunlight and converts it into electrical power. Automatically turn on at night or in dark environment, auto turn off at dawn.
FAQHow to know that the button is at "ON" position?
Cover the solar panel with your hand and if the light is on, then the button is at "ON" position.
