As a special special vehicle, the safety performance of the sprinkler mainly depends on the stability of the braking system. How to choose a braking system for a sprinkler? What is an oil brake sprinkler or an air brake sprinkler? This depends on the performance and shape of the sprinkler to determine what kind of braking system is needed.
What is an air brake?
â—† The air brake is generally applicable to large vehicles such as medium and large trucks, large and medium buses, heavy trucks, and buses.
â—† Air brake refers to the brake system with compressed air as the medium, which is applied to commercial vehicles with total mass greater than 3.5T. The gas brake is commonly known as the "air brake". Such a car cannot reach a certain pressure after it is started.
â—† The air brake of the sprinkler consists of air compressor, brake valve, brake air chamber, air reservoir, barometer, and trachea (bold) safety valve. When the brake is on, the brake valve is opened and the compressed air is pushed to push each brake cam. The brake force is only related to the air pressure and the valve opening degree in the air reservoir, and has nothing to do with the strength of the lower tread. When the engine is not started, it can only be braked by the compressed air stored in the air reservoir. After a few times (there are pneumatic valves, air horns, etc.), if the engine cannot start without sufficient air pressure, it will not brake at all.
What is the oil brake?
â—† The oil brake is generally suitable for small cars: such as cars, minivans, small and medium vans, and micro cards are oil brakes.
â—† The oil brake can be braked only with the oil pump sub-pump. The load is less than 10 tons. Some of the 19 medium-sized passenger cars use the oil brake.
â—† When the main brake pump, sub-pump, and tubing (smaller) are used to brake the oil pump, the main pump piston is pushed when the brake is applied. The oil is compressed and the work of the sub-pumps is driven. Therefore, the braking force is related to the magnitude and intensity of the stepping. Ancillary equipment; the engine can continue to operate the brake without starting.
What is the difference between air brake and oil brake?
â—† The oil brake is simple in structure, small in size and easy to install. All cars use oil brakes.
â—† The oil brake can apply the brakes continuously. The oil brake is sufficient for a small car. â—† The disadvantage of the oil brake is that the reaction speed is slightly slower, but the brake is gentle and the force is small.
â—† The air brake has a complex structure and the air bladder has a certain volume and can only be installed in large vehicles.
◆ Air Brake If you press the brakes continuously, the “compressed air†suddenly disappears. At this time, you need to wait a few seconds to be full of air.
â—† The air brake is relatively stable and responsive, but it requires a large braking force, a long use distance, and a fast reaction speed.
â—† The air brake does not use brake fluid, but the clutch requires brake fluid!
â—† The braking force of the air brake is larger than that of the oil brake, so the overloaded car likes to use the air brake. And the maintenance of air brake brakes is convenient and cheaper.
Air brake and oil brake on the price of sprinkler?
The same configuration of the sprinkler, steam brake sprinkler relative to the oil brake sprinkler price is more expensive, but the price difference is in the thousand or so, the increase in the cost reflected in the entire sprinkler on the proportion is not much, the price of the sprinkler Has little effect.
