Air Compressor System Analysis Program

1. Compressed air system common anomaly

(1) purchase of air compressor
a. Taking into account the time of purchase only machines are cheap, poor quality found, operation unstable, long downtime, resulting in production downtime.
b. running time of purchase only consider the stability of the neglect of the energy consumption ratio, over time enormous waste.
c. Procurement ignored the quality of service suppliers, troubleshooting not been able to attend, spare parts procurement inconvenience, are causing unnecessary losses.

(2) System Planning
a. air compressor capacity is too large, resulting in higher compressor energy waste load.
b. filter installed too many large pressure loss, high energy waste.
c. air compressor is not centralized gas supply, but scattered distribution throughout the whole plant, pipelines independent, not only increasing the equipment purchase costs, also increased pipeline costs, management costs and operating expenses.
d. air compressor room ambient temperature is too high, the equivalent of reducing the compressor efficiency, exhaust to reduce energy consumption increases.Environmental temperature is increased by 100C, the equivalent of about 3% lower efficiency air compressor.
e. pipeline layout is unreasonable, elbow joints too much, increase the pressure loss.

(3) system control and management
a. air compressor outlet pressure value is set too high, resulting in increased energy consumption, the formation of waste.Pressure for each additional 1 kg/cm2, energy consumption increased by about 6%.
b. the same time more than one air compressor or both for loading and unloading for capacity control action (part load) operation, increase energy waste;
c. poor maintenance or outdated machine is not maintained, the accumulation of small defects Cheng Kung failure, shortened life of the machine man.
d. too dirty room environment, causing air compressor of the filter, oil filter, oil separator and the cooling oil frequently replaced.
e. line of precision filter does not change in time, resulting in pressure loss is too large, the energy waste.
f. serious and I do not know the pipeline leak, a new purchase to supplement the insufficient amount of air compressor, resulting in waste.To a 7 kg/cm2g, 10 mm leak calculation, assuming electricity one yuan / kWh, 8000 hours a year would be a waste of 320,000 yuan in electricity bills.
g. condensate in the compressed air system hazards.

2. How to make your compressed air system for your money?

(1) purchase of equipment
a. use of ten years of computing, accounting for 5-10% of equipment costs, maintenance costs account for about 5-10%, electricity consumption costs account for about 80-90%.So first thing to consider when purchasing the machine's efficiency, energy conservation would mean money.
b. ease of operation and maintenance of stability is equally important consideration to be.
c. Note that the quality inspection service providers.

(2) Science Planning
a. air compressor the size of the number of units required careful calculation.
b. post-processing equipment is not possible, but necessary configuration.
c. Room should be selected in a clean environment, well-ventilated place.
d. layout to minimize the elbow pipe, fittings, pipe diameter should be a reasonable choice.

(3) system control and management
a. air compressor outlet pressure set as low as possible, just enough.
b. load running the air compressor as far as possible, reducing load time.
c. periodic maintenance to extend machine life.
d. maintaining clean room environment.
e. Cha Du leak point in time.

In short, we recommend that you purchase and use of compressed air in the planning of equipment:
1. Considering the equipment efficiency, operation stability, ease of maintenance and service quality.
2. Choose a professional supplier of equipment for overall planning.
3. Science use and management of compressed air system.
