The piston moves up and down in the inlet valve of air compressor to control the work of air compressor. When the air compressor starts, stops and no load, the relief solenoid valve uses the air inlet to supply air to the piston, so that the piston is closed up; When the air compressor works under full load, the discharge solenoid valve stops the discharge and the piston chamber is discharged from the exhaust outlet. The piston of the air inlet valve drops due to the difference in inlet pressure. The air inlet valve is fully open and the air compressor works under full load. When the pressure reaches the upper limit of the set pressure, the discharge solenoid valve loses power and begins to discharge, and the piston of the air inlet valve is pushed up to make the air inlet valve in the closed state. The space-time press is in no-load state. The structure of piston type air inlet valve includes air inlet, valve upper cover, piston, base, discharge solenoid valve. Speed control. That is, the flow rate is adjusted by changing the speed of the air compressor, while the opening of the valve remains unchanged (generally, the maximum opening is maintained). When the speed of the air compressor changes, the head characteristics of the air supply system change, while the pipe resistance characteristics remain unchanged. In this control mode, the speed of the air compressor motor is changed through the frequency conversion speed regulation technology, and the air supply flow of the air compressor can be changed with the change of the air flow, achieving a true balance of supply and demand. It can save energy at the same time. Make the whole system reach the best working efficiency. The inverter is based on the principle of AC-DC-AC power conversion, and can output AC voltage with continuously adjustable frequency according to the needs of the controlled object. The motor speed is proportional to the power frequency. Therefore, using the AC voltage with adjustable output frequency of the inverter as the power supply voltage of the air compressor motor can easily change the air compressor speed.China Electric Air Compressor factory website:http://www.jsdrilltools.com/ai....r-compressor/electri

Related products: Flammulina velutipes powder [What is Flammulina velutipes] Flammulina velutipes is also known as winter mushroom, sclerophyllum, streptomycetes, etc., belonging to the phylum Fungi, Basidiomycotina, Layer Fungi, Agaricus, Tricholomaceae, and Desmodium. Flammulina velutipes is widely distributed in nature, and is cultivated in China, Japan, Russia, Europe, North America, Australia and other places. Flammulina velutipes is widely distributed in my country and has a long history of cultivation. From Heilongjiang in the north, Yunnan in the south, Jiangsu in the east, and Xinjiang in the west, it is suitable for the growth of Flammulina velutipes. Flammulina velutipes is rich in protein, also contains vitamins such as VB1, VB2, and VC, and is rich in minerals such as calcium, phosphorus, and iron, and is very nutritious. Flammulina velutipes also contains 18 kinds of amino acids. Each 100g of fresh mushrooms contains 8 kinds of essential amino acids, accounting for 42.29%~51.17% of the total amino acids. The content of arginine and lysine in essential amino acids is higher than that General mushrooms. Because it is rich in arginine and lysine, as well as a variety of minerals and vitamins, it plays an important role in the growth of children's intelligence, so the Japanese call it "enhancing intelligence." [Function] Flammulina velutipes also contains functional ingredients with unique effects, such as proteins with multiple pharmacological effects and polysaccharides with anticancer effects. These ingredients make Flammulina velutipes more valuable.China Flammulina Velutipes Extract website:http://www.jinghebio.com/mushr....oom-extract/flammuli
