How to save energy more effectively of air compressor, energy saving scheme of air compressor

According to your statement, your unit uses an oil-free screw machine, and the total gas consumption is relatively large, and the system requirements are relatively high. In fact, there are many aspects to start with when it comes to energy saving.

1. Understand the pressure demand of the system, the minimum, and the pressure drop for instantaneous use. Reducing the pressure of the system network can reduce the work done by the air compressor. Here's an example:

The ZR200 has a current of 400 A at 9 bar and only 380 A at 8 bar, so that the upper limit can be lowered and energy consumption can be saved. This one is relatively easy to operate.

2. You can choose 1-2 of them to be controlled by adding inverters. This effect is more obvious, and it is really energy-saving (that is, the upfront cost is relatively large). The operating state of the air compressor is realized through the pressure of the pipe network.

3. Thermal energy**. The heat generated by the air compressor is used to heat boiler water, production water, and bathroom water. This is quick and environmentally friendly. Generally, the investment can be recovered in up to 1 year.

4. Check the leakage point of the pipeline and deal with it in time.

5. Use an adsorption dryer with heating, which can save 6-7% of air consumption, and reduce air consumption is to reduce electricity consumption.

Hope the above can help you.

Use an automatic pressure gauge on an air compressor to set the minimum and maximum pressure, and automatically stop the automatic operation, and you can do it.

Do frequency conversion constant pressure control, compressor group control management, increase gas storage tanks, learn more about:

Air compressor is a common power equipment, is a large consumer of power in the factory, usually a large amount of heat discharged by the air compressor is directly discharged through air cooling or through the cooling tower of water cooling to the atmosphere, usually this part of the energy is wasted, the gas compression process of the air compressor can be divided into two parts: adiabatic compression and constant pressure cooling, in the process of adiabatic compression, under standard conditions, when compressed to 8 kg, the temperature of the compressed air can reach more than 260 degrees, in order to ensure its reasonable operating temperature, The air compressor continuously injects oil from the head for cooling, and the oil-gas mixture that takes away the heat is then dispersed into the atmosphere through the cooler, which can confirm that the cooling and heat dissipation of the air compressor is not only large, but also has a high temperature, and this heat can be used according to the laws of thermodynamics.

Advantages of installing air compressor waste heat**.

1 Create a new era where heat does not require energy, and there are no running costs.

2. Safe, hygienic, convenient and reliable way to take heat.

3. Improve the operation of the air compressor and improve the operation efficiency of the air compressor.

4. Heat is not affected by time, weather and season, as long as the air compressor is on, it can be heated at all times.

5. Truly achieve zero emission, and the energy saving benefits are significant.

Air compressors include large mining centrifuges, screw machines or piston machines used in ordinary factories, and so on. The consumption of additional power is also a reason for comparison

Air compressor energy saving is a systematic project, not just from a certain aspect to solve the problem

1. Leakage: pipeline and end user leakage, this amount is very large, generally the leakage of the factory after 2 years of operation can reach more than 20%, so the most effective and fast should be the leakage control, regular inspection, this process is a long-term work, need to be adhered to, can not be carried out raid;

2. End users: users need to optimize, such as gas equipment improvement, process improvement, pressure adjustment, etc., just like the principle of energy-saving lamps, the terminal must be saved, which is also relatively easy to achieve, and needs on-site workers to ponder;

3. Group control: because the user's gas consumption is not a constant flow, the number of air compressors is the number of units that meet the maximum gas load, so when the gas load is reduced, most of the air compressors are in the unloading state, which belongs to just eating and not working, this part of the electricity is very considerable, and the deployment of the number of units by using the group control system can solve this problem very well;

4. Pressure reduction: transform the original fishbone-shaped pipe network into a ring network, so that the outlet pressure can be appropriately reduced, which can also save energy;

5. Change frequency: If the gas load fluctuates particularly large and the cycle is also very frequent, the group control system should be supplemented by frequency conversion transformation, which is not only easy to allocate the number of units, but also can well control the outlet pressure, which is also conducive to the reduction of the low pressure limit;

In short, this work is a system engineering, which needs to be managed according to the actual situation and adapted to local conditions.

1. Control leakage.

It is estimated that a small hole of 1mm, under a pressure of 7bar, has a leakage of about 1mm, check all the transmission pipe network and gas points, especially joints, valves, etc., and deal with the leakage points in time.

Second, pressure drop management.

Set up a pressure gauge through the pipeline section to detect the pressure, check the pressure drop of your sections in detail, check the maintenance of the pipe network section in time if there is a problem, the general air compressor outlet to the gas point, the pressure drop can not exceed 1bar, and the strict raw baby is not more than 10%, that is, the pressure drop of the cold and dry filter section is general. The factory tries to arrange the annular pipe mega network to balance the air pressure at each point.

3. Adjust the pressure matching of gas equipment.

Evaluate the pressure demand of the gas consuming equipment, and reduce the exhaust pressure of the air compressor as much as possible in the case of production. For every 1 bar reduction in the exhaust pressure of the air compressor, the energy saving is about 7%-10%.

Fourth, adjust the unreasonable use of gas.

According to data analysis, the electric energy utilization rate of the air compressor is only about 10%, and about 90% is converted into heat energy and lost. At the same time, the use of compressed air for routine cleaning should be resolutely eliminated.

Fifth, the use of centralized control mode.

If the number of air compressors is small, a frequency conversion air compressor can be used to regulate the pressure, and if the number is large, centralized linkage control can be used to avoid the rise of stepped exhaust pressure caused by the parameter setting of multiple air compressors.

6. Do a good job in equipment maintenance and cleaning.

Increase the heat dissipation effect of the air compressor, the exchange effect of water cooling, air cooling and other heat exchangers to keep the oil clean.

7. Waste heat of air compressor**.

**Hot water is generated from the heat of the air compressor oil system for use in other processes or auxiliary living facilities.

8. Renovation or replacement of drying system.

The waste heat of the air compressor is used for drying and dehydrating the compressed air with the waste heat of the new drying equipment, and the energy saving rate is more than 80%.

9. The system is covered by energy-saving transformation.

Zhongke Yujie intelligent air compressor power saver greatly reduces the starting current of the compressor through voltage regulation and soft start, so as to avoid the impact and damage caused by excessive starting current to the equipment 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, the pressure stability can also be obtained by using the gas equipment production process, which is very conducive to the control of product quality of the enterprise.
