After the disassembly and washing, assemble the negative pressure Pump in the opposite direction. During the assembly process, pay attention to the following points: First, do not install the wrong position of the cylinder wall, and the air outlet hole faces upward. If the position is wrong, the positive and negative pressure may be reversed. When installing the cylinder wall and cylinder head, do not tighten the mounting screws first. After the main rotor of the motor is powered, the screw is adjusted and tightened. This makes it easy for the cylinder to contact the pump core by gravity. The cylinder head and the cylinder wall are optimally matched. In this process, a few drops of lubricating oil can be added to the air pump to reduce the moving friction. This step is critical. If the assembly is not good, it is easy to cause the motor card shaft or negative pressure suction to fail to meet the requirements.
If the negative pressure gauge is connected before the oil window is not installed, if the negative pressure of the gas pump can reach the normal value, the oil window can generally meet the requirements when used. The third is to install the slide, please do not install the opposite direction. In addition, otherwise the sealing performance is not good, affecting the negative pressure. Install the slide, the cylinder cover should be covered before the motor is tested, so as to prevent the slide from injuring people. Fourth, when installing the oil ring, check whether the oil ring is evenly rounded. After installation, power on the motor to see if it rotates with the motor main shaft. The oil window should be placed on the oil line. Too much will be wasted with the pump. Too little to achieve the purpose of lubrication and sealing.
Solar cells use sunlight to generate electricity. As long as the sun shines on the battery, it will continue to generate electricity. It is a clean energy with the advantages of safety, reliability, no noise and no consumption of raw materials. It has the advantages of great convenience for residents in remote areas. So what is the working principle of solar energy? Today we'll explore it. Solar cell is a device that directly converts light into electric energy through photochemical effect. When sunlight shines on the semiconductor pn junction, a new hole (electron pair) is formed. Under the action of the electric field, the hole flows from the N region to the p region, and the electron flows from the p region to the N region. After the circuit is connected, a current is formed to convert light energy into electric energy.Solar panel, also known as solar cell module, is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is an assembly composed of several solar cells assembled on a plate in a certain way. It is the core part of the solar power generation system.The earth, the green home for human survival.
With the development of human civilization, it has gradually become a victim of economic growth. Clean energy is imminent.
The sun concentrates 99.87 percent of the mass of the solar system, and one twenty-two percent of the energy radiates to the earth, becoming the main source of photosynthetic heat on the earth. Solar energy is one of the cleanest, most lasting and most magical energy of all.
