There are many air compressor brands on the market. Many customers really don't know how to choose a suitable air compressor. In fact, choosing an air compressor is nothing more than the brand of the air compressor. The price of the air compressor is the most important thing. The stability of the air compressor. There is also the after-sales service.
Air compressor selection follows the following principles:
1) Scientific planning
the size and number of air compressors should be carefully calculated and determined.
· Post-processing equipment is not the more the better, but as needed to configure.
The computer room should be selected as far as possible in a clean and well-ventilated place, preferably away from dust.
Pipeline layout to minimize the elbow, joints, pipe diameter selection should also be reasonable.
2) Gas consumption planning
1. The capacity of the air compressor is too large, resulting in high waste of no-load energy of the air compressor.
2. Too many filters are installed, the pressure loss is large, and the energy waste is high.
3. Air compressor is not centralized gas supply, but scattered configuration in all parts of the plant, pipeline independent, that is to increase the cost of equipment acquisition, but also increased the cost of pipeline and operation and maintenance costs.
4. The ambient temperature of the air compressor room is too high, which is equivalent to reducing the efficiency of the air compressor, reducing the exhaust volume and increasing the energy consumption. For every 100 ℃ increase in ambient temperature, the efficiency of the air compressor is reduced by about 3%.
5. The pipeline layout is unreasonable, the elbow joints are too much, and the pressure loss is increased.
3). system control and management
1. The air compressor outlet pressure value is set too high, resulting in increased energy consumption and waste. Every 1 kg/cm increase in pressure
2
increase energy consumption by about 6%.
2. Multiple air compressors at the same time for loading and unloading action or at the same time for capacity adjustment (partial load) operation, increase energy waste;
3. The machine is not well maintained or expired, minor defects accumulate into major failures, and the life of the machine is artificially shortened.
4. The environment of the machine room is too dirty, resulting in frequent replacement of the filter, oil filter, oil and gas separator and cooling oil of the air compressor.
5. The precision filter of the pipeline is not replaced in time, resulting in large pressure loss and serious energy waste.
6. The air leakage in the pipeline is serious and unknown. A newly purchased air compressor is used to supplement the insufficient air volume, resulting in waste. 7 kg/cm in one place
2
the calculation of 10mm leakage point, assuming that the electricity charge is 1 yuan/degree, 8000 hours a year will waste 320000 yuan of electricity charge.
7. Try to let the air compressor full load operation, reduce the no-load time.
8. Regular maintenance, extend machine life
9. Maintain the clean environment of the computer room and check and block the air leakage point in time.
4) Purchase of equipment
based on the ten-year service life, the equipment purchase cost accounts for about 5-10%, the maintenance cost accounts for about 5-10%, and the power consumption cost accounts for about 80-90%. Therefore, the working efficiency of the machine should be considered first when purchasing, and energy saving means making money.
· Operational stability and ease of maintenance are also important factors to consider.
Pay attention to the quality of after-sales service of suppliers.
Air compressor outlet pressure set as low as possible, just enough.
1. Common unreasonable phenomena of air compressor system
1). The purchase of air compressor is unreasonable
1. When purchasing, only considering the cheap price of the machine, it is found that the quality is too poor, the operation is unstable, and the downtime is long, resulting in the loss of production downtime.
When purchasing, only consider the operation stability and purchase cost, ignoring the use cost of the air compressor itself, resulting in huge waste over time.
3. The supplier's after-sales service quality was ignored during the purchase, the failure to arrive in time for troubleshooting, and the inconvenience of purchasing spare parts caused unnecessary losses.
In summary, we recommend that when planning the purchase and use of air compressor equipment:
1, comprehensive consideration of equipment efficiency, operation stability, maintenance convenience and after-sales service quality.
2. Select professional equipment suppliers for overall planning.
3, scientific use and management of air compressor
In the operation of most compressors, there are complex problems such as low efficiency, unsatisfactory equipment operation parameter setting, equipment mismatch, large pressure loss of pipe network, unscientific early selection, system leakage, artificial demand, incorrect use and inappropriate system control, etc.
Textile processing and production process, including proofing, marking, cutting, sewing and other processes, many of which need to use compressed air. Granklin oil-free air compressors have been in the textile industry for many years, helping to provide high-quality textile products, including high-pressure series air compressors.
1 Air Compressor Introduction There are three main types of mainstream air compressors: centrifugal air compressor, screw air compressor, and piston air compressor. 1.1 centrifugal air compressor centrifugal air compressor is driven by the impeller gas to do high-speed rotation,
Under the current economic environment, manufacturing enterprises are becoming more and more difficult to do, and oil-free air compressors are very profitable due to their large capital. Each enterprise is seeking to tighten the company's operating costs, and the cost of energy consumption is the most important. And what you don't know is a lot of waste.
Which brand of screw air compressor is of good quality? granklin air compressor for you to sort out the top ten brands of air compressor granklin and other air compressors in 2021.
View detailsWith the rapid development of Internet technology, it is becoming more and more convenient to purchase oil-free screw air compressors. Just search the Internet "air compressor" a lot of information related to it will be displayed in front of everyone, so how to in this a lot of letters
The full name of the air compressor is the air compressor, which is the main body of the air source device. It is a device that converts the mechanical energy of the motor into gas pressure energy, and is a pressure generating device for compressed air. So how can the air compressor adjust the pressure? If the air compressor is adjusted
Air compressor since its birth, has been in constant progress. Especially in recent years, screw air compressor can be said to develop rapidly. Power is also constantly changing, such as permanent magnet variable frequency screw air compressor, based on the current production level, the level of mass production is also increasing, the price
Screw air compressor procurement how to choose a good manufacturer? General equipment air compressor industry manufacturers, agents face the danger of being eliminated at any time. In this case, air compressor enterprises strive for perfection on the road of R & D and production, and constantly improve product quality. Water lubricated air compressor manufacturers, Shanghai granklin (group) co., ltd. is doing better and better in the production of oil-free screw air compressors, focusing on product quality and after-sales companies, allowing users to purchase with confidence.
View detailsScrew air compressor sometimes work for a long time, resulting in the phenomenon of high temperature, especially in the summer, when the temperature is too high fault often occurs, then the air compressor temperature is too high is how to return a responsibility? 1. Poor environmental ventilation and heat dissipation There are three main situations in which the surrounding environment of the air compressor affects heat dissipation: first, it is too close to wall-like obstacles; Second, there are other heat sources near the air compressor; third, the front door and side doors of the air compressor are open during operation, and the fan cannot form strong airflow.
