At this stage, the air compressor market mainly focuses on high energy efficiency and low energy consumption. However, when choosing an air compressor, energy efficiency is not the primary consideration. When selecting an air compressor, you should first consider safety, reliability, whether it meets your own gas needs, and finally economy.
- Reasonable selection
The more scientific selection steps are: working pressure-volume flow-power supply capacity.
- Work pressure. Determining the required working pressure at the gas end is the primary consideration when selecting an air compressor. What needs to be taken into consideration is the reduction in pressure loss caused by pipelines and post-treatment equipment;
- Volume flow. First, comprehensively and systematically understand the volumetric flow of all gas-consuming equipment. And multiply the volumetric flow rate of all equipment by 1.2;
- Power supply capacity. The volume flow rate and working pressure of the air compressor have nothing to do with the power changes of the air compressor, but are related to the changes in rotation speed. After the air compressor speed changes, the exhaust volume will also change accordingly.
Before selecting an air compressor, you need to consider the volumetric flow rate and working pressure, and select the power of the air compressor. At the same time, the power supply capacity needs to meet the power requirements of the air compressor.
At present, it seems that many companies need to update and transform old equipment. Nowadays, many factories, especially large and medium-sized enterprises that have been established for more than ten years, use a variety of air compressor equipment models, and some are old products with high power consumption, difficulty in spare parts storage, and heavy maintenance. The operating efficiency of many old equipment in operation is less than 60% of the rated displacement, let alone compared with the latest energy-saving air compressors. However, because the problem of parallel connection of multiple devices is not prominent, it is not taken seriously. Some companies believe that reducing production costs means cutting investment in equipment maintenance and upgrades, rather than upgrading and transforming old equipment. But the operating cost of an air compressor consists of three components: initial purchase cost, maintenance cost and energy cost. Energy costs account for approximately the majority of air compressor operating costs. If the old equipment currently in service can be updated into high-efficiency and energy-saving air compressors, the amount of electricity saved will be considerable. Energy-saving modifications can also be carried out on the air compressor, which will not only reduce the no-load running time of the equipment, but also reduce the impact on the air compressor and the wear of the motor bearings, reduce the amount of maintenance and repairs, and greatly reduce operating costs.
- Improve operational efficiency
Although some companies choose air compressors with high energy efficiency levels, they do not pay attention to maintenance and maintenance, and cannot maintain good equipment operating habits. This certainly cannot ensure that the air compressor operates efficiently. To improve the operating efficiency of air compressors, the main thing is to strengthen the maintenance and repair of equipment. At the same time, pay close attention to the cooling effect of the air compressor, and the inlet air temperature should not be too high. Reducing the failure rate of these ancillary equipment, improving power-saving operation, selecting a more efficient cooling water pump, reducing the loss of compressed air in the compressed air pipeline, and reducing pipeline leakage can all improve the operating efficiency of the air compressor and reduce operating costs.
