Rotary air compressors india

Types of rotary air compressors

A rotary air compressor takes constant air and compresses it to be used in various equipment, tools, and machinery with the help of two screws rotating. There are two types of rotary air compressors in India:

• Oil-flooded rotary air compressor

  The oil-flooded rotary air compressor is built to utilize oil to cool and lubricate the compressor element while also sealing the air compression chambers. This specific oil component can flood the compression area, boosting thermal energy transfer within the compressor and lowering the temperature of the compressed air. An oil separator in the design of the oil-flooded rotary air compressor, which typically consists of a bag filter and a coalescing oil separator, removes the compressor oil from the air stream before the compressed air enters the air receiver or storage tank. This approach separates the oil, permitting a portion of it to drain back into the compressor for lubrication while also preventing residual oil from entering the end user's air system or tools.

• Oil-free rotary air compressor

  Oil-free compressors, as the name suggests, have no oil elements in the compression chamber. They are made to deliver compressed air that meets cleanliness criteria. To achieve this goal, air is compressed using lubricating elements like Teflon or heat-dissipating metal components. High-energy electric motors commonly power oil-free rotary compressors to attain their prescribed horsepower. Although ideal for applications that demand and uphold stringent air quality requirements, such as food and beverage, pharmaceutical, or precision instrumentation, oil-free rotary compressors may be more expensive than their oil-flooded counterparts.

Specifications & maintenance of rotary air compressors in India

Regular maintenance is necessary for a rotary screw air compressor to work well over its lifespan. Users can extend the rotary compressor's life and boost its performance by performing some routine maintenance procedures on it.

• Daily checks: Every day before using the compressor, the user should check the oil level in the separator to ensure it is within the suitable operating range. They should also examine the air intake filter and inspect it for damage or dirt buildup. After that, they should clean or replace it if necessary.
• Weekly maintenance: People who use their rotary compressors weekly should spend some time for maintenance. Weekly maintenance involves checking and adjusting all belts' tension and inspecting the hoses for leaks or signs of wear. Also, users should drain the moisture from the air receiver tank weekly. Moisture accumulation can lead to corrosion inside the tank.
• Monthly maintenance: Monthly maintenance tasks include replacing the air intake filter with a new one and inspecting all electrical connections and terminals to see if they are tight and free from corrosion.
• Quarterly maintenance: Quarterly maintenance involves changing the oil in the oil separator and inspecting the condensate drain valve for clogs and proper functioning.
• Every six months: According to manufacturers' manuals, users should service the compressor after every six months. Users should replace the intake filter with a new one. They should also check the performance of the thermostatic valve and the functioning of the condensate drain valve.
• Annual maintenance: Annual maintenance requires replacing the separator oil and the intake filter. Also, the following components should be inspected and cleaned: thermostatic valve, air receiver tank, condensate drain valve, condensate trap, and intercoolers and aftercoolers. Additionally, all moving parts should be lubricated. Further, the compressor should be calibrated, and its reverse ratchet set adjusted.
• Every two years: Users should replace the electric motor bearings and drive belt after two years. They should also conduct a system leakage test and replace the following components if they find any defects or signs of damage: air receiver tank, intercoolers and aftercoolers, thermostatic valve, and condensate trap.
• Every three years: After three years, rotary compressor users should replace the motor drivers and electric motor seals. Further, they should change the oil in the condensate drain valve.
• Cleaning: The external surfaces of the rotary air compressor should be cleaned regularly to prevent dirt and dust from accumulating. Further, the airflow passage and cooling fins should be cleaned to prevent any overheating issues from developing.
