Advantages of Screw Compressor

Can run continuously

A screw compressor is built and optimized for continuous operation and can therefore withstand load rates of up to 100%.

Suitable for harsh conditions

A screw compressor can operate in harsh weather conditions. Whether the temperature is high or low, the screw compressor can produce compressed air.

Very reliable

A screw compressor is a very reliable machine because it can withstand high load rates and harsh conditions.

Simple maintenance

The continuous operation of the screw compressor and fewer material parts, means that it does not wear as quickly, which can reduce the need for maintenance costs.

Generates lower temperature

The screw compressor generates lower temperatures than other types of compressors. This means that regardless of load and pressure, the compressor temperature will be kept at a constant temperature.

Energy efficient

Screw compressors are more energy efficient than other types of compressors, e.g. piston compressors. When running the same amount of time, they will have been more efficient and therefore have used less energy.

Less condensate

The screw compressor's lower operating temperature means that less water/condensate is formed during compression. It reduces the amount of condensate that can end up in your compressor, equipment and end products.

Silent operation

The design of the screw compressor helps to provide a low noise level, and many screw compressors run at very low noise levels compared to other compressor types.

Applications of Screw Compressor

HVAC Systems
In Heating, Ventilation, and Air Conditioning (HVAC) systems, screw compressors are used for:
Refrigeration: Essential in commercial refrigeration units, cold storage facilities, and air conditioning systems.
Chillers: Used in large industrial chillers for cooling and maintaining temperature control.

Energy Sector
The energy sector employs screw compressors in several ways:
Oil and Gas: Used in gas gathering, gas lift, and gas transmission applications.
Power Generation: Utilized in turbine and generator applications for both cooling and pneumatic operations.

Mining and Construction
In mining and construction, screw compressors are vital for:
Drilling: Providing compressed air for drilling rigs and equipment.
Material Handling: Powering pneumatic tools for cutting, grinding, and lifting materials.

Chemical and Petrochemical Industries
These industries use screw compressors for:
Process Gas Compression: Compressing process gases in chemical manufacturing and petrochemical refining.
Nitrogen Generation: Providing compressed air for nitrogen generation and other gas separation processes.

Transport
In transport, screw compressors are used for:
Railways: Providing compressed air for braking systems, door operations, and other pneumatic controls.
Ships: Used in marine applications for various onboard systems, including air conditioning and refrigeration.

Different Drive Modes of Screw Compressors

Belt Drive

These compressors are very robust as well as easy to install and maintain. In addition, they have the lowest initial investment cost among rotary screw compressors. This combination makes them a great choice for smaller operations.

Gear Drive

A gear drive makes compressors quieter. The investment is higher than a belt drive but also more energy efficient. Therefore, if you use the compressor a lot, this investment will pay off over time thanks to energy savings.

Direct Drive

This is the optimum of rotary compressor technology. The innovative direct drive offers unmatched efficiency and performance. Among the three, they create the least noise. Direct drive rotary screw compressors come in different types - from a basic design for the smaller models to those with ultra-efficient variable speed drives.

Precautions For Use Of Screw Compressors

Foundation and Location
The screw type compressor must be placed on a flat, solid surface, avoiding soft soil or unstable ground. This ensures stability during operation and prevents vibrations that could damage the machine.

Electrical Configuration
Select the appropriate power cable size and verify the voltage’s accuracy. Incorporate necessary safety devices such as air switches and fuses into the power supply line.

Piping Configuration
Ensure the main pipeline has a 10-20-degree downward slope to facilitate condensate drainage and prevent moisture accumulation.

Motor Rotation Check
Before first startup or any change in power supply, verify the motor’s rotation direction to prevent oil starvation and potential damage to the screw type compressor head.

Operational Safety
Never loosen, disconnect, or tamper with piping components, fittings, or devices while the compressor is running. High-pressure, high-temperature fluids within the system can cause severe injuries.

Operational Pressure Limits
Never operate the compressor above the maximum discharge pressure specified on its nameplate to prevent damage.

Safety Valve Monitoring
The safety valve, installed on the oil-air separator, releases excess pressure if it exceeds the set limit. Immediately investigate the cause of overpressure whenever the safety valve activates.

Lubricant Selection
Use only the screw air compressor-specific oil recommended by the manufacturer. Avoid mixing different brands of lubricant as it can compromise the compressor’s performance.

Regular Inspections
Routinely inspect critical components such as the motor, temperature sensors, pressure transmitters, control panel, wiring, and oil-air separator filters. Neglecting these inspections could lead to fire hazards.

Professional Assembly
The compressor’s main assembly requires specialized skills. Users must refrain from disassembling the compressor’s core components without the assistance of highly trained technicians.

FAQ

Q: How Often Is Oil Changed for a Rotary Screw Compressor?

A: Checking and changing the oil is one of the most important maintenance tasks for an oil-injected rotary screw air compressor. Depending on your compressor model and the type of oil used, you can expect to change the oil every 4,000 – 8,000 hours. However, if your rotary screw air compressor is operating in a dirty environment, the oil may need to be changed more often.

Q: How Often Are Filters Changed for a Rotary Screw Compressor?

A: Air compressor filters (including air intake filters and inline filters) should be changed at a minimum every 2,000 hours for a rotary screw air compressor. If your environment is very dirty, you may need to change filters more often.

Q: How Often Does Water Need to Be Drained for a Rotary Screw Compressor?

A: Water should be drained for a rotary screw air compressor at least daily, if not more often. To reduce maintenance time, look for automated drain valves. Electric drain valves can be set to open on a timer to drain condensate regularly. A zero-loss drain valve uses a float mechanism to activate the drain, so it only opens when needed. This can reduce compressed air loss.

Q: What are the basic operating principles of screw compressor?

A: A screw compressor works with a male and female rotor that rotate in the opposite direction. This movement draws in air that is compressed as the space between the rotors and their housing decreases. The compressed air is then displaced to the outlet.

Q: How many hours is a screw compressor good for?

A: Piston-type (reciprocating) compressors typically last about 10,000 - 20,000 hours before a rebuild is necessary. On the other hand, a rotary screw compressor will last between 80,000 - 100,000 hours.

Q: How to clean a screw compressor?

A: It is recommended to use compressed air to clean the inside and outside of the air filter element of the screw air compressor without omission in all aspects. After completing these steps, restore the scene and check whether the value of the pressure switch is in the normal value.
