Swiss low pressure screw air compressor maintenance

It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!). Check the isolation of the motor windings. Should be in the mage-ohms (you need an isolation tester / high voltage ohm meter for this). Check the voltage when the compressor is running. [pdf]

Who makes oil-free screw compressors?

Since starting to manufacture and provide oil-free screw compressors in 1955, KOBELCO has delivered over 2,500 units to users all over the world, representing a large number of applications such as oil/gas, oil refineries, chemicals, and ironmaking. KOBELCO started to manufacture and provide oil-injected screw compressors in 1974.

What are the different types of air compressors?

The main product series include permanent-magnet variable frequency air compressor, oil-free air compressor, two-stage compression screw air compressor, low-pressure screw air compressor, magnetic levitation air compressor, etc.

What is a screw compressor?

Screw compressors are positive-displacement compressors that feature space-saving designs, low maintenance costs, continuous operation and compatibility with a wide range of gases. There are oil-free (dry) types that prevent oil contamination of the process gas, and oil-cooled (wet) and screw refrigerator (ref) types that inject oil.

What are the advantages of SCR low pressure screw compressor?

WHY CHOOSE SCR LB/LBPM SERIES SCR provides you with more energy-efficient equipment and more considerate services. 1.Special design for low pressure application-big air flow, low pressure. 2.Multi point oil automatic injection technology .

Drill rig noise levels

However, our extensive experience in this field has shown that drilling rigs tend to produce noise levels of 60 to 65 dBA at a distance of 500 ft from the rig. Effective noise control measures can significantly reduce sound levels. Reductions of 10 dBA or more are usually achievable. [pdf]

FAQS about Drill rig noise levels

How much noise does a drilling rig make?

The overall noise levels depend on the actual equipment used on the rig. However, our extensive experience in this field has shown that drilling rigs tend to produce noise levels of 60 to 65 dBA at a distance of 500 ft from the rig. Effective noise control measures can significantly reduce sound levels.

How do you predict the noise impact of a drilling rig?

Perform calculations, or utilize noise modeling software to predict the noise impact at locations where compliance must be achieved. The predicted noise levels should be based on noise measurements conducted on the actual rig that will drill the wells.

What causes loud noise in a drilling rig?

Loud noises are caused by pumps and trucks. The methods for reducing the noise are similar to the methods for drilling rigs: All equipment should be maintained properly. Modern lower noise equipment can be used.

How to reduce noise from drilling operations?

These structures are designed with materials that absorb sound waves, rather than reflecting them, which significantly reduces the noise levels that reach the surrounding environment. Enclosures are another effective strategy for mitigating noise from drilling operations.

Why should you create a noise map for a drilling operation?

Once you have created a noise map for a drilling operation, you can introduce controls to start protecting workers against the problem noise. Using the maps, mitigation measures such as modifying or replacing equipment with quieter models can be taken.

Does drilling cause noise?

Drilling operations, whether for oil and gas exploration, construction, or mining, are notorious for generating high levels of noise that can have adverse effects on workers and nearby communities.
