Product Description: Due to fluctuations in raw material prices, the cost and models may vary. For specific quotations, please contact our sales staff. Thank you.In the depths of the mine, darkness and uncertainty coexist, with risks such as falling rocks and collapses posing threats to miners' safety. The mine-used anti-impact protective vest, as a crucial piece of protective equipment for miners, silently safeguards them in the narrow underground spaces. With it, there is an extra layer of reassurance. So, this is what a mine-used anti-impact safety vest looks like! Its main body consists of rigid protective plates made from special materials capable of withstanding certain impacts. Below the vest, there is a thoughtfully designed waist protection section that curves slightly upward to provide support for the lumbar spine. The vest comes in a bright orange-yellow color, making it highly visible in dimly lit mine environments!Features of the mine-used anti-impact safety vest:After wearing, it allows freedom of movement and does not interfere with workers' normal labor or other tasks.The product is thoughtfully designed, with a rational structure, aesthetically pleasing appearance, ease of use, low impact force, lightweight, compact size, and portability.Parameters of the mine-used anti-impact safety vest:Size: Small, Medium, Large, Extra LargeModel: YH-3, YH-2, YH-1, YH-0Height (cm): 180Vest Length (cm): 55.5±0.5, 57.5±0.5, 59.5±0.5, 61.5±0.5The mine-used vest, particularly the anti-impact safety vest, weighs only about 0.5 kilograms. It consists of straps, protective plates, cushioning padding, and connectors. The bakelite plates are interconnected and can flex with the back's movement, while multiple foam blocks are placed where the vest contacts the back. Here’s a quick guide on how to correctly wear the mine-used reflective anti-impact vest. First, loosen all adjustment buckles, drape the vest over your back to allow it to naturally conform to your back’s curve, then tighten the shoulder and waist straps in sequence to ensure the vest is securely fixed without shifting or wobbling. Quickly check if you’ve worn it correctly.Contact: Manager Hu Mobile: 16653525598 more>

Complete Collection of Air Compressor Pulley Accessories: Fan Impeller, Single Groove, Double Groove, Type A, Type B, Iron Flywheel for Air Pump with Free Shipping.
$99
Category: Machinery & Equipment/Compression & Separation Equipment/Vacuum Impregnation Equipment
Company: 优气压缩机(上海)有限公司
Product Description: Air Compressor Flywheel is a mechanical device used to store rotational kinetic energy, primarily applied in air compressors to balance the power system, adjust speed, and store energy. The flywheel has a large moment of inertia, functioning similarly to an energy storage unit. It can absorb and release energy during different operational phases of the air compressor, thereby improving the stability and efficiency of the power system.Working Principle of the FlywheelThe working principle of the flywheel is based on changes in angular momentum. During the operation of the air compressor, the flywheel absorbs rotational energy during the power stroke and releases energy in other strokes (such as intake, compression, and exhaust), thereby balancing the power output of the system and reducing vibrations and fluctuations. The angular velocity and moment of inertia of the flywheel determine the amount of energy it can store. Therefore, by adjusting the mass, size, and angular velocity of the flywheel, its energy storage efficiency can be optimized.Application of Flywheels in Air CompressorsIn air compressors, the main functions of the flywheel include:Connection and Startup: The flywheel assists in starting the air compressor by engaging with the starter's ring gear.Energy Storage and Balancing: The flywheel can absorb and release energy during different operational phases of the air compressor, helping to balance the power output of the system and reduce vibrations and fluctuations.Speed Adjustment and Power System Balancing: By storing and releasing energy, the flywheel can adjust the speed and power output of the air compressor, enhancing overall operational efficiency and stability.Structural Features of the FlywheelThe flywheel is typically a disc-shaped component with a large moment of inertia, with its mass concentrated on the rim to achieve efficient energy storage and release. There is a strict relative positional relationship between the flywheel and the crankshaft, usually ensured by positioning pins or asymmetrically arranged bolts to maintain balance during disassembly and assembly. more>
