Oil-free air compressor for bottle blowing machine

The oil-free air compressor for bottle blowing machine is the key equipment in the gas source device of the bottle blowing machine. It is responsible for converting mechanical energy into gas pressure energy and providing clean, dry and oil-free high-pressure gas for the bottle blowing machine. The following is a detailed introduction of oil-free air compressor for bottle blowing machine:

1. working principle

the working principle of the oil-free air compressor is mainly to compress the inhaled air through mechanical parts such as pistons, screws or turbines, and then output it as high-pressure gas. The specific process includes:

1. compressed air intake: Inhale outside air through the air inlet, and conduct preliminary filtration and dust removal through the filter screen.
2. cylinder compression: The initially filtered air enters the cylinder, and the cylinder is driven by the crankshaft to reciprocate to realize the compression of the gas.
3. Cooling system: The cooling system (such as heat sinks, cooling fans, etc.) radiates heat from the mechanical components to ensure the stable operation of the equipment.
4. Gas separation: The water vapor is condensed into liquid water through the cooler and discharged, and then the oil vapor and solid particles are filtered out through the filter to ensure the purity of the output gas.
5. Compressed air output: The treated compressed air is sent to the air storage tank for storage, and then transported to the place where it needs to be used through the pipeline.

2. product features

oil-free air compressor for bottle blowing machine has the following characteristics:

1. air is pure because no lubricating oil is used, the compressed air is cleaner and purer, which is especially suitable for the blow molding machine industry with high air quality requirements.
2. Environmental protection and energy saving: The oil-free design reduces the use of lubricating oil, does not produce waste oil, and is conducive to environmental protection. At the same time, oil-free air compressors usually adopt advanced energy-saving technologies, such as frequency conversion speed regulation, efficiency motors, etc., to improve the energy efficiency ratio.
3. Simple maintenance: No need to change lubricating oil frequently, reducing maintenance costs. At the same time, the internal structure of the oil-free air compressor is relatively simple and easy to operate.

3. product selection

when choosing an oil-free air compressor for a bottle blowing machine, the following factors should be considered:

1. ventilation and pressure: According to the gas demand of the bottle blowing machine, select the appropriate exhaust volume and pressure. For example, a bottle blowing machine may require 30 to 40kg of high-pressure gas.
2. Compression mode: Oil-free air compressor has screw type, piston type and other compression methods. The screw compressor has the advantages of stable operation, low noise and high efficiency, and is suitable for long-term continuous work; the piston compressor has simple structure and convenient maintenance, and is suitable for small bottle blowing machines.
3. Cooling mode: There are two cooling methods: water cooling and air cooling. The water-cooled cooling effect is good, but it needs to be equipped with a cooling water system; the air-cooled type does not need a cooling water system, but the heat dissipation effect may be slightly inferior to the water-cooled type.
4. Brand and service: Choose well-known brands and reputable suppliers to ensure product quality and after-sales service. At the same time, should understand the supplier's after-sales service system, including installation and commissioning, maintenance, troubleshooting and other aspects of support.

4. market conditions

at present, there are many manufacturers on the market to provide oil-free air compressors for bottle blowing machines. The product models are rich, and the prices range from several thousand yuan to several hundred thousand yuan. For example, the oil-free silent screw water-lubricated air compressor provided by a certain brand costs about 999 yuan/set, which is suitable for small bottle blowing machines. However, the price of oil-free screw compressors of high-end brands may be as high as several hundred thousand yuan, which is suitable for large bottle blowing production lines.

Precautions for the use of 5.

1. Installation Environment: The oil-free air compressor should be installed in a well-ventilated, dry, non-corrosive gas environment to ensure the normal operation of the equipment and extend its service life.
2. Regular maintenance although the oil-free air compressor does not need to change the lubricating oil frequently, it still needs regular maintenance, such as cleaning the filter screen, checking the seals, etc., to ensure the stable operation of the equipment.
3. Safe operation: Operators should be familiar with the operating procedures and safety precautions of the oil-free air compressor to avoid equipment damage or casualties caused by misoperation.

Generally speaking, the oil-free air compressor for bottle blowing machine is one of the indispensable equipment in the bottle blowing machine production line. When selecting and using, the performance, price, brand and service of the equipment should be fully considered to ensure the stable operation of the equipment and extend its service life.
