Air compressor in india

Types of air compressors

An air compressor in India is a machine that increases the pressure of air by reducing its volume. It is used in many industries and comes in different types to suit specific applications.

• Rotary screw air compressor:

  Generally, rotary screw air compressors are designed to produce a large amount of compressed air continuously. It is the most commonly used air compressor type in manufacturing industries. The working principle of a rotary screw air compressor is to enclose the air in the two screw rotors, which are twisting and grooved cylinders. While the two cylinders are rotating at high speed, the space between the grooves reduces. The reducing space moves the air forward and at the same time compresses it. This continuous process is what produces a steady stream of compressed air.

• Reciprocating air compressor :

  The mechanism of a reciprocating air compressor is similar to that of a piston engine. It uses a motor-driven piston that moves back and forth within a cylinder to draw in air and compress it. The compressed air is then stored in a tank for future use. A feature of the air compressor is the temperature control system that helps regulate the working temperature and prevent overheating during operation. Because of this working principle, a reciprocating air compressor can produce compressed air in high pressure. Thus, it is ideal to use for applications that need a high pressure of air like small workshops, garages, spray painting, blowing debris, inflating car tires, etc.

• Scroll air compressor:

  A scroll air compressor has two spiral-shaped scroll discs. One of the scroll discs is fixed while the other one orbits around it. The movement creates pockets that suck in and compress the air. The continuously orbiting motion moves the compressed air to the discharge outlet. Some advantages of scroll air compressors are being oil-free designed and very low noise during operation. Thus, they are suitable for use in dental clinics, hospitals, laboratories, and food-processing companies.

• Dynamic air compressor:

  A dynamic air compressor is a kind of air compressor that works by using centrifugal force to compress air. The compression happens when a rotating impeller increases the speed of the air and a diffuser then converts the high-speed air into high-pressure air. Dynamic air compressors can produce a large volume of compressed air at a relatively low pressure. So, it is often to use to support production lines in the manufacturing industries.

Specifications and Maintenance

Specifications

• Operating pressure: A small air compressor's typical range is 90 to 120 psi. High-pressure air compressors can reach up to 175 psi or more.
• Cubic foot per minute (cfm) flow rate: This determines the amount of compressed air produced. It usually ranges from 1 to 10 cfm for small compressors and 10 to 50 cfm for larger ones.
• tank size: It stores compressed air. Tank sizes range from 1 gallon for portable compressors to 60 gallons or more for stationary ones. 60-gallon tanks are the most common for big air compressors.
• Horsepower (hp) rating: It represents the motor's power driving the compressor. Portable air compressor in India often range from 1 to 3 hp. Larger belt-driven or stationary compressors can be 5 hp or higher.
• Duty cycle: This indicates how long the compressor can run during a 10-minute period. Many portable air compressors have a 60% duty cycle, allowing them to run for 6 minutes and rest for 4 minutes. Belt-driven compressors may have a 70% or 80% duty cycle.

Maintenance

• Regular oil changes: This is crucial especially for lubricated air compressors. Change the oil after the first 100 hours of break-in and then every 500 hours of operation after that. Check the oil level before each use and add more if it's below the halfway mark.
• Drain the tank weekly: Compressed air collects moisture in the tank. Draining the tank removes moisture to prevent rust and corrosion. Open the drain valve at the bottom of the tank to let the water out until it runs clear. Then close the valve.
• Inspect hoses and fittings monthly: Look for signs of wear, cracking, or damage. Replace any hoses that are leaking or damaged. Also, check that all the fittings are securely attached. Lubricate threaded fittings with pipe thread sealant if they're not used frequently.
• Clean the air filter quarterly: Air filters prevent dust and debris from entering the tank. Check the filter every three months. Tap it against a hard surface to dislodge dust. If heavily clogged, wash it with soapy water, dry completely, and then reinstall.
• Check the belt tension semi-annually: Belt-driven air compressors have belts that require proper tension for efficient power transmission. Examine the belt every six months. If it sags, adjust the tension until there's a slight bow when pushing down on the belt. Follow the manual for specific adjustment instructions.
• Inspect for leaks annually: Compressed air leaks waste energy and reduce efficiency. Check all fittings, hoses, and the tank for leaks at least once a year. Use soapy water to spray suspected areas then look for bubbles indicating a leak. Promptly repair any leaks found.
