Saman diesel mobile screw air compressor, easy to move and with high output capacity

The mobile screw air compressor is an industrial equipment used for air compression, mainly applied in fields such as mining, shipbuilding, chemical industry, and transportation. It is driven by electric motors or diesel/gasoline engines that meet Euro II emission standards. It uses a 380V/50Hz three-phase power supply, has a protection level of IP54, and is suitable for outdoor operations in hot and dusty environments. The entire machine is equipped with multiple safety protection systems and a digital dashboard.

This equipment is centered on the direct connection of large-diameter screw rotors for drive, and features a stepless intake regulation system and plate-fin type cooler to ensure efficient operation and adaptability to high temperatures. Patent improvements include a base interlocking structure to enhance mobility, multiple layers of gradually varying density filter cotton tubes to enhance air filtration efficiency, and an integrated tank design with oil-gas separation and gas storage functions to reduce purchase costs. Through technologies such as ball rotation and sliding limit of support columns, the stability of the equipment is optimized, and safety lifting hooks and waterproof power boxes are equipped to meet industrial requirements. The equipment has passed China's first-level energy efficiency certification, with significant energy-saving effects.

Main exhaust system

The connection between the main exhaust and the oil separator body joint pipe is changed to a flange connection, which can more effectively prevent oil leakage in long-term use of the high-pressure single-stage unit.

Supply air system

One 2" ball valve and three 1/4 ball valves, sufficient for users to connect various sizes of equipment

Conical R thread is easier to seal, has a long service life, and is less prone to air leakage

On the side of the separator cylinder replacement, reduces exhaust resistance

Temperature control valve

Ingersoll Rand patented new temperature control valve, can effectively prevent the temperature control element from malfunctioning or not functioning (getting stuck), ensuring the compressor operates in the appropriate temperature range, and more reliably extending the service life of the lubricating oil and the main unit.

Power box

The old-fashioned air switch is a manual switch, the higher the voltage, the greater the difficulty of opening and closing

While this unit adopts an electromagnetic air switch, which can be easily manually operated, also controlled by a button, and is equipped with a circuit breaker, greatly increasing safety

Mobile screw-type air compressor

Intake system

Continuous intake adjustment system can be adjusted within 0-100%

The unit cover is designed according to the cold box principle

It can form an efficient cooling airflow, with a maximum working environment temperature of up to 52℃

Overall safety lifting ears

Can be lifted and locked at a single point to prevent unauthorized movement

Intake filtration system

The equipment is equipped with a two-stage air filtration system to ensure the air compressor is not damaged by dust and dirt particles. When it is necessary to replace the filter, the indicator light will promptly warn you.

Self-designed cooling system

High-performance plate-fin type cooler

The cooling area margin is increased, ensuring the cooling effect

The maximum operating environment temperature can reach up to 52℃

(The motor specification suggests that it is not advisable to operate the unit for a long time above 46℃)

Safety protection

Compressor exhaust temperature high protection: >120℃

Main motor overload protection

Fan motor overload protection

Power phase sequence error or phase missing protection

Oil filter blockage alarm Electrical control box

High-capacity contactor, capable of adapting to unstable voltages in the field

Waterproof design for the box

Large internal space, good heat dissipation performance for components

Power supply box

Waterproof design for the box to prevent rain from entering during shutdown (do not turn on the machine when it's raining)

Bottom inlet, convenient wiring, while maintaining a distance from surrounding workers to ensure personal safety

Maintenance and servicing

Front and rear maintenance doors facilitate maintenance and servicing

Portable screw air compressor

10-20.7 bar, 23.5 meters/minute - electric

High processing accuracy, minimum air leakage, low wear, long lifespan

Advantages and features

High reliability:

The compressor has few components and no wear-prone parts, so it operates reliably with a long service life. The major overhaul interval can reach 4 to 80,000 hours.

Easy operation and maintenance:

The automation level is high. Operators do not need to undergo long-term professional training and can achieve unmanned operation.

Good power balance:

There are no unbalanced inertial forces, allowing for smooth high-speed operation. It can be operated without a foundation, especially suitable for mobile compressors. It has a small size, light weight, and occupies less space.

Strong adaptability:

It has the characteristic of forced gas supply, and the volumetric flow rate is almost unaffected by the exhaust pressure. It can maintain high efficiency within a wide range of rotational speeds. Product Description

Announcement Editor

Main unit:

It adopts a large-diameter screw rotor. The main unit is directly connected to the diesel engine through a high-elastic coupling, without a speed-increasing gear in the middle, resulting in better reliability; the rotational speed of the main unit is consistent with that of the diesel engine (not exceeding 2400 r/min), and the service life is longer.

Drive equipment:

It is generally divided into: electric motor, diesel engine, gasoline engine

The diesel engine or gasoline engine is selected from domestic famous brands such as Dongfeng Cummins and Yuchai, meeting the requirements of Euro II emission standards, with low fuel consumption, and having a nationwide after-sales service system, allowing users to receive prompt and comprehensive services.

Adaptability is good:

The diesel mobile air compressor can automatically adjust the diesel engine throttle (exhaust volume) according to the size of the gas consumption, without wasting a drop of diesel. This is equivalent to the frequency conversion control of the electric screw machine.

Operating parameters:

The operating parameters are clear at a glance and have multiple prompt, alarm, and shutdown protection functions.

Intake system

The butterfly valve mechanism has both on-off regulation function and continuous regulation function. The stepless regulation system range can reach 0-100% for the gas path control, which is safe and reliable.
