Best price portable diesel air compressor for sand blasting for sale is based on the proven European original model of the Group's headquarters. It is designed to enhance the reliability of the cooling system, dust control system, operating system and unit in the Asian market. In addition to maintaining the inherent advanced technology, stable quality, excellent performance, reliable operation, easy operation and maintenance, energy saving, quiet and so on, it is more suitable for various complex working conditions in Asia, especially China, to meet customer needs.

1.Main Engine

As we all know, the main engine is the heart of the screw air compressor, its performance directly affects the economics and life of the whole machine operation, and the cost also accounts for more than 30% of the whole machine. The high-pressure mobile screw compressor screw mainframe adopts the original Atlas Copco Group Size 2 series two-stage compression high-pressure main engine, the output pressure can reach 17-21 kg, high efficiency and good reliability;

The mainframe is delivered by the Swedish Atlas Copco Group. The mainframe's production base is recognized as the world's largest and most advanced screw air compressor mainframe manufacturer.

The Atlas Copco patented host uses an advanced SAP line. Its characteristics are:

1)The diameter of the yin and yang rotors is equal. Compared with 5/6 teeth or 4/5 teeth, the female rotor has higher rigidity, so it is not easy to be deformed, and the internal leakage loss is small;

2)has the best tip speed;

3)The main body type is made by grinding, and the precision of the screw is higher. Minimize the impact and vibration of the machine and effectively extend the life of the moving parts.

The  high-pressure mobile screw compressor has a compact structure, small size, light weight, high efficiency and reliable operation. The noise of the equipment is only 77-85 decibels, which indicates that the moving parts of the compressor have high processing precision, excellent materials, small impact and vibration, and long rotor life, reflecting the relatively high level of machine design and processing.

The Atlas Copco mainframe is highly efficient, and the optimum screw speed makes it more than 5% more energy efficient than similar products on the market. The trouble-free time and life of the main rotor depends largely on the life of the bearing. The bearings of the Atlas Copco mainframe are bearings for SKF (both in Sweden and the mutual participation of Atlas Copco). The service life is more than 20% longer than the average bearing.

2.Diesel Engine

YUCHAI diesel engine with stable quality and long service life.

The GIII EFI diesel engine is specially designed for construction machinery and China's vast and complex areas, especially considering the application of high altitude. It can operate safely at an altitude of 3,000 meters without any adjustment, and it is easy to start. The fuel economy is good, with low exhaust pollution and low noise.

The diesel engine is equipped with a four-stage fuel filtration system based on actual conditions in China: coarse filtration + pre-filtration (original Atlas fuel filtration), and primary and secondary filters with water separator. Ensure fuel cleanliness and engine performance. Make the whole unit more energy efficient and last longer.

3. Transmission Mode

The  high-pressure mobile screw compressor adopts the elastic coupling direct-coupled transmission mode, and the transmission efficiency is high. The flexible coupling is imported from Atlas Copco, which can reduce the shock vibration of start-stop, loading and unloading. The main engine and the motor flange are connected by a coaxial connecting barrel to ensure the coaxiality between the main unit and the motor and improve the operational reliability.

The  high-pressure mobile screw compressor uses the original imported gearbox supplied by Atlas Copco and is manufactured to the AGM13 standard. It is the highest in the world (the same level as the gearbox on the Air Bus) to ensure that the gearbox is in It will not be damaged under the harsh working environment. The general foreign screw machine gearbox is manufactured by AGM11 standard, which is lower than Atlas Copco.

4. Gas volume control and regulation system

The unit adopts Atlas Copco's original unloading valve, and the air volume adjustment mode is proportional adjustment + ON-OFF adjustment + speed adjustment. The adjustment mode can automatically adjust the intake air amount of the unloading valve

intake port and the diesel engine speed according to the change of the user's air consumption (0 to 30%). When the amount of compressed air required by the user is smaller, the relief valve is completely closed (ie, ON) -OFF adjustment) and the diesel engine is in the idle position, so this adjustment method is more efficient, fuel consumption is lower, and energy is saved.

5. Cooler

The oil cooler of  high-pressure mobile screw air compressor adopts aluminum alloy plate finned cooler, which is light in weight and high in heat exchange efficiency.

The oil cooler increases the heat exchange area by 30% according to the calculation, and the margin is large, which is more suitable for the actual working conditions of the construction site of the Chinese mobile machine. Although the cost of the manufacturer is increased, the user uses, the cleaning and maintenance cycle is long, the exhaust temperature is low, and the performance of the machine is more stable and reliable.

6. Temperature Control Method

The exhaust temperature of the screw compressor should be controlled to not lower than the ambient temperature +50 ° C, otherwise the water vapor in the oil-gas mixture will precipitate, causing the emulsification of the lubricating oil. Therefore, the temperature control valve should be set so that the oil supply temperature is not lower than the set value.

This machine adopts the oil temperature control valve to adapt to the operation under different ambient temperatures, while the oil temperature maintains the optimal range to prevent the precipitation of moisture in the compressed air and ensure the service life of the lubricating oil. The temperature sensing element automatically controls the ratio of entering the oil cooler and bypass according to the exhaust temperature to achieve the purpose of temperature control.

7. Oil and Gas Separation System

The high-pressure mobile screw air compressor generates a lot of heat during the working process. Usually we need to spray lubricating oil into the main machine, which mainly plays the role of heat absorption, sound absorption, lubrication and sealing, because through the exhaust port. The oil and gas mixture is discharged and needs to be treated by the oil and gas separation system to save operating costs (fuel consumption) and ensure the cleaned gas. Our company's oil and gas separation system uses imported oil and gas separation components with good effect and long service life. Under normal conditions, the oil content of exhaust gas is ≤ 5ppm.

8. Air Filtration System

The high dust dust is one of the main working conditions of the mobile screw air compressor in the field. The  high pressure machine series mobile screw air compressor adopts the German MANN air filter with rotary point + coarse filter + safety filter, safe. Reliable, large filter area, low filtration resistance, good filtering effect, even in the harsh environment of the field, it can effectively remove dust and prolong the service life of main engine, engine oil and oil separator.

9. Fuel Filtration System

The diesel engine is equipped with a four-stage fuel filtration system based on actual conditions in China: fuel oil (Atlas inlet) + fuel pre-filter (Atlas inlet), and third and fourth secondary filters. Ensure that the fuel is clean and the performance of the engine is guaranteed. Make the whole unit more energy efficient and last longer.

10. Control Panel
