The relationship between air compressor discharge pressure and energy saving

Analysis of the relationship between air compressor exhaust pressure and energy saving

1. The definition of exhaust pressure is related to energy consumption
exhaust pressure refers to the compressed air pressure (such as 0.6-0.8MPa) output by the air compressor, and its setting value directly affects the energy consumption of the equipment. In theory, the higher the compressed air pressure, the greater the compression resistance to be overcome, and the energy consumption increases. Therefore, the exhaust pressure and energy saving are "reverse correlation"-the closer the pressure setting is to the actual demand, the lower the energy consumption; on the contrary, the excess pressure will lead to energy waste.

2. Reasonably set the exhaust pressure of the energy-saving logic

• demand matching: Gas equipment (such as pneumatic tools, instruments) usually has rated pressure requirements. If the exhaust pressure is higher than the demand, the air compressor needs to continue to run at high pressure, consuming additional power; if the pressure is insufficient, it may affect equipment performance or production efficiency.
• Avoid "high" pressure: Some users deliberately increase the exhaust pressure for "insurance", but compressed air will naturally reduce pressure due to friction, leakage and other factors during pipeline transportation, and the actual pressure at the gas end may be close to the required value. Therefore, accurate matching of demand pressure is the key to energy saving.

3. Technical Adaptability of Granklin Air Compressor
granklin water lubricated single screw air compressor through the following design, optimize the balance of exhaust pressure and energy saving:

• efficient compression technology single screw and star wheel continuous rotation compression, reduce energy loss, even in the lower exhaust pressure can still maintain efficient operation;
• intelligent control system: It can monitor the pressure demand of the gas end in real time, automatically adjust the running state of the air compressor, and avoid the energy waste of the "big horse-drawn trolley" type;
• low pressure loss design: Water lubrication technology reduces component friction, cooperates with optimized flow channel design, reduces energy loss during compression, and further improves energy saving effect.

4. Practical advice: how to achieve energy saving through exhaust pressure management

• demand Research: Count the rated pressure of all gas-using equipment, and take the highest value as the reference value of the air compressor exhaust pressure (avoid over-increasing the pressure for a certain equipment alone);
• periodic calibration: Monitor the actual gas end pressure through the pressure gauge or intelligent system. If it is lower than the set value of the air compressor for a long time, the exhaust pressure can be appropriately reduced;
• leakage management: Pipeline leakage will cause pressure loss. Regular inspection and repair of leakage points can reduce the additional energy consumption caused by pressure compensation.

Conclusion
the reasonable setting of exhaust pressure is one of the core links of energy-saving operation of air compressor. Granklin water-lubricated single screw air compressor through high-efficiency compression technology, intelligent control and low-loss design, to help users accurately match the gas demand, in the protection of production efficiency at the same time, effectively reduce energy consumption, to achieve green low-carbon operation.
