First, control the leakage.
According to the calculation, the leakage of a small hole with a diameter of 1mm under the pressure of 7bar is about1.5l/s. Check all the pipeline networks and gas consumption points, especially the joints and valves, and deal with the leakage points in time.
Second, the pressure drop control
Set pressure gauges to detect the pressure according to the pipeline segments, and check the pressure drop of each segment in detail. Inspect and maintain the pipeline network section with problems in time. Generally, the pressure drop from the outlet of the air compressor to the gas consumption point should not exceed 1 bar, strictly speaking, it should not exceed 10%, that is, 0.7bar, and the pressure drop in the cold-dry filtration section should generally be 0.2 bar .. The factory should arrange an annular pipe network as far as possible to balance the gas pressure at each point.
Third, adjust the pressure matching of gas equipment.
Evaluate the pressure demand of gas equipment and try to reduce the exhaust pressure of air compressor under production conditions. When the discharge pressure of air compressor is reduced by 1bar, the energy saving is about 7%- 10%.
Fourth, adjust unreasonable gas use behavior.
According to the data analysis, the electric energy utilization rate of air compressor is only about 10%, of which about 90% is converted into heat energy and lost. It is necessary to evaluate whether the pneumatic equipment of the enterprise can be solved by electric means. At the same time, we must resolutely put an end to the use of compressed air for daily cleaning.
Fifth, adopt centralized control mode.
If the number of air compressors is small, a variable frequency air compressor can be used to adjust the pressure. If the number is large, centralized linkage control can be adopted to avoid the stepped increase of exhaust pressure caused by the parameter setting of multiple air compressors.
Six, do a good job of equipment maintenance and cleaning.
Increase the cooling effect of air compressor and the exchange effect of heat exchangers such as water cooling and air cooling, and keep the oil clean.
Seven, air compressor waste heat recovery
Recover the heat from the oil system of the air compressor and prepare hot water for other processes or auxiliary living facilities.
VIII. Modification or replacement of drying system
The new drying equipment uses the waste heat of air compressor to dry and dehydrate compressed air, and the energy saving rate is over 80%.
Nine, the system energy saving transformation
The energy saver of Zhongke Yujie intelligent air compressor greatly reduces the starting current of the compressor through voltage regulation and soft start, which avoids the impact and damage to the equipment caused by excessive starting current when the compressor starts. According to the user's demand for compressed air, the motor power is accurately matched to avoid waste; At the same time, pressure stability can also be obtained by using gas equipment production process, which is very beneficial to product quality control of enterprises.
