10 steps to save energy with compressed air systems

6. Review Piping Infrastructure.

Many systems aren't optimized. A piping system design should optimize transfer of compressed air at the desired flow and pressure to the point of use. Increasing the size of a pipe from two to three inches can reduce pressure drop up to 50 percent. Shortening the distance air has to travel can further reduce pressure drops by about 20-40 percent. The more flow through a pipe the greater the pressure drop will be. Pressure drop in a pipe increases with the square of the increase in flow, which means if the flow is doubled, the pressure drop will increase four times. Air distribution piping should be large enough in diameter to minimize pressure drop.

Characteristics and industry misunderstandings of oil-free ...

Author: Bella Zhang

With the development of society and the improvement of the quality of compressed air sources in all walks of life, the demand for oil-free air compressors has increased year by year; compared with traditional oil-free piston compressors, oil-free screw air compressors have low noise, The characteristics of stable air volume and lower failure rate are well received by the market. Oil-free screw compressors are divided into dry oil-free screw compressors and water-lubricated oil-free screw compressors (water-injection oil-free screw compressors). , The water-lubricated oil-free screw machine is further divided into: single-screw water-lubricated oil-free screw machine and twin-screw water-lubricated oil-free screw machine. At present, the single-screw water-lubricated oil-free screw machine is widely used in the market.

The single screw water lubricated oil-free screw compressor has the following characteristics:

1. Compared with the same power and the same pressure, the dry oil-free screw machine has a larger displacement and is more energy-saving;

2. The maximum pressure of single-stage compression can reach 16 kg, and the maximum pressure of two-stage compression can reach more than 40 kg; it can solve dry oil-free screw compressors (currently there is only one factory in China, and some models have 12.5 kg models) Embarrassing situations of up to 10 kg of pressure;

3. Near isothermal compression: air-cooled compressor host temperature rise ambient temperature +22~24&#;; water-cooled compressor host temperature rise ambient temperature +14~15&#;;

4. There is not a drop of oil in the self-lubricating bearing and compression system. When the inhaled gas is oil-free, the exhaust gas is absolutely oil-free, and there is no oil pollution;

5. Lower maintenance costs: daily maintenance consumables are air filter and water filter; lubricating water is automatic water replenishment, no need to manually add water, and no need to stop during the process of automatic water replacement;

6. The existing water-lubricated oil-free screw compressors and systems generally use food medical grade materials such as SUS304, which are clean and hygienic, and are more in line with the hygiene standards of the pharmaceutical and food industry;

7. The use of water to lubricate the compressed air contains fewer impurities and is cleaner;

8. Due to its natural explosion-proof characteristics such as near-isothermal compression, corrosion resistance, water spray lubrication in the compression chamber of the main engine, and no sparks in metal and non-metal meshing, it will be widely used in the field of special process gas compressors.

Several aspects of single-screw water-lubricated oil-free screw machines have been misunderstood:

1. The vast majority of people (including those in the compressor industry) think that the compressed air discharged from the water-lubricated oil-free screw machine has a large water content?

Comair Product Page

Qualified water-lubricated oil-free screw compressor products have no liquid water when the compressed air is discharged, that is to say, it is saturated compressed air. The water content of saturated compressed air is only related to two factors: pressure, temperature; the same pressure The lower the temperature rise, the less the water content; the water-lubricated oil-free screw compressor is close to isothermal compression, and the water content is the lowest among all air compressor models, for example, compared with oil-injected screw compressors Under standard conditions, the moisture content is more than 25% lower.


2. Most people think that the water-lubricated oil-free screw machine consumes a lot of water, so it is necessary to replenish water inside the machine, and the machine has to drain the water all the time, thus wasting a lot of water?

The water-lubricated oil-free screw machine does not need to be replenished with water all the time. There is a water level sensor in the machine that can automatically drain and replenish water. The water change and oil change have a certain cycle, for example, the water change cycle is 100 hours. It is said that there is no need to add water to the machine within 100 hours. Taking a 250 KW machine as an example, the water change volume is 200 liters each time. Calculated according to 8,000 hours a year, 16,000 liters of water need to be changed, which is 16 tons of water. The tap water is almost Calculated at 32 tons, 5 yuan per ton of water requires 160 yuan per year for water, which is very water-saving and money-saving.


3. Most people think that water-lubricated oil-free screw machines are the same as water-lubricated and water-cooled?

You can think of lubricating water as the lubricating oil of the fuel injector, and its cooling methods are also divided into air cooling and water cooling. Take the SEN model as an example: 5.5~37KW standard air cooling, 45KW~280KW standard water cooling (Optional air cooling).


4. Most people think that the compressed air discharged from the water-lubricated oil-free screw machine contains a lot of bacteria and cannot be used in the pharmaceutical and food industry?

After washing with water, the bacteria in the air are cleaned in large quantities. The filter in the compressor can partially filter the bacteria, and the discharged compressed air contains very little bacteria; the dry oil-free screw machine can pass through the operating temperature higher than 170 &#;. High temperature kills the vast majority of bacteria, but since both have pipelines, gas storage tanks, and post-processing that are transported to the terminal gas, it is impossible to guarantee the possibility of non-existence and breeding of bacteria, so it is necessary to install a sterilizing filter at the terminal , so there is no difference between the two; the author has nearly 20 years of experience in the compressor industry, water-lubricated oil-free screw compressors are widely used in various industries, especially in the pharmaceutical, food, and medical industries (including finished compressed air Contact with the products produced), it has never been unusable because of bacterial problems, but it can better reduce the troubles of oil, dust and odor problems in compressed air for customers.


5. The lubricating effect of using water as lubricant is not good, and the service life of the machine is short?

The bearings of the compressor host are lubricated with grease. The fully sealed grease imported bearings have a service life of 70,000 to 100,000 hours. Generally, the maintenance time of the host is less than 40,000 hours or less, so it will not affect the normal operation of the whole machine. Used, qualified water lubricated machines are designed to have a service life of not less than 25 years.

After years of market verification, the single-screw water-lubricated oil-free screw compressor has grown from immature and niche products to mature and used in all walks of life. With the increase in production capacity and cost reduction, it has replaced some traditional At the same time, the oil compressor will definitely replace a certain proportion of the oil-injected screw machine in the future to benefit the society.
