Commercial "cars", whether they are buses or trucks, are undoubtedly the "safety" issue as the biggest concern of operators.
The air compressor is the first energy supply device for the brake system. However, this key equipment has become a "big hidden danger" for commercial vehicle operators.
linsheng said that the main applications of air compressors in the car are: brake system, door pump and clutch sub-pump, air suspension. Based on the above special needs, the air compressor has the following requirements: safe and reliable, energy-saving and high-efficiency, high air quality, light weight, small size, low noise and low maintenance cost.
In the current key parts of the new energy electric bus and heavy-duty brake air compressor customers are extremely dissatisfied with the top three, the air compressor is always among the best.
The oil sliding vane air compressor and the oil piston air compressor used in the braking system of the new energy bus basically have the phenomenon of lubricating oil penetration. On the one hand, the oil leakage has a fire point, which may cause the automobile to burn. On the other hand, Once the lubricating oil leaks, the air compressor will stop working. Once the air supply is stopped, the vehicle will brake and cause life safety.
The traditional lubricating oil air compressor has only IP56 (not waterproof and dustproof) in the protection level, and it is emulsified in the air and the internal lubricating oil when the air is compressed under the rainy and humid environment (or low temperature environment). The air compressor is faulty. In the cold weather in the north, the car starts preheating for more than 20 minutes, resulting in increased energy consumption.
The traditional vehicle air compressor also has emulsification, oil leakage, oil shortage, fire and explosion, high energy consumption of 50%, high maintenance cost, about 1200 yuan per year...
In view of safety issues, operational efficiency and maintenance costs, the local bus operation company's maintenance department is actively promoting the replacement of new equipment that is safer, more stable and more energy-efficient.
Driven by the market, a new generation of oil-free scroll air compressors has emerged.
linsheng said that the characteristics of the oil-free scroll compressor are: safe, oil-free; zero maintenance, and no need for preheating, energy saving of operation of more than 50%. The operating principle is that the fixed scroll and the movable scroll maintain a small radius of plane motion in a certain phase, and the movable and fixed scrolls mesh to form a plurality of crescent-shaped closed compression chambers, and the gas sucked into the working chamber is subsequently formed into a crescent-shaped compression. The cavity is gradually compressed, and then the exhaust port at the center of the static disk is discharged.
