To estimate the usage of compressed air in the plant, a comprehensive analysis of equipment list, process parameters and system losses shall be carried out. The following is a systematic estimation process based on industry practice:
| Device Type | gas consumption per unit (m & sup3;/min) |
|---|---|
| pneumatic wrench | 0.3-0.8 |
| sandblasting machine | 2.0-5.0 |
| bottle blowing machine | 1.5-3.0 |
| CNC machining center | 0.8-1.2 |
| Industry type | air density (m & sup3;/min · output value of ten thousand yuan) |
|---|---|
| auto Parts | 0.8-1.2 |
| food & Beverage | 0.5-0.9 |
| textile printing and dyeing | 1.0-1.5 |
through the above method, the plant compressed air demand model can be established. It is recommended to review every 2-3 years, especially after process changes or equipment increases or decreases. For new plants, the analogy method can be used to reserve 20-30% of the expansion capacity by referring to the gas consumption data of the same type of plant.
When comparing oil-free air compressors with oil-free air compressors, both have their own unique advantages and application scenarios. Therefore, it is not possible to generalize which is better, but to choose according to specific needs and use environment. Oil-free air compressors, as the name suggests, have worked in
Whether the silent air compressor needs refueling depends on its type. Silent oil-free air compressor does not require refueling. This type of air compressor adopts oil-free lubrication technology, and the internal moving parts do not need to rely on lubricating oil for lubrication. Its working principle is through self-lubricating piston or other special
In the air compressor market, water-lubricated air compressors have attracted much attention due to their unique advantages and applications. Among them, Shanghai Granklin Group as a professional air compressor manufacturer, its production of water lubricated screw air compressor products are based on its excellent performance and wide range
The air time of the air compressor can be adjusted. There are mainly the following methods to adjust the air time of the air compressor: Adjust the pressure switch: The pressure switch is an important part of the air compressor. By adjusting the adjustment knob on the pressure switch, the start of the air compressor can be changed
Mechanical processing plants do use compressed air, which plays a vital role in mechanical processing. The following is a detailed explanation of this: The role of compressed air provides power: compressed air is often used as a power source in mechanical processing to drive various pneumatic workers
Small air compressors are usually not considered special equipment. Special equipment generally refers to boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, hoisting machinery, passenger ropeways, large amusement facilities and yards (factories) that involve life safety and are more dangerous.
Whether the air compressor needs to use an explosion-proof box depends on the specific use environment and safety requirements. The following is a detailed analysis of this problem: Use environment: If the air compressor is used in a flammable and explosive environment, such as petroleum, chemical, mining, gas, etc.
The main differences between air compressor frequency conversion and power frequency are reflected in the working principle, energy efficiency performance, starting characteristics, noise level, pressure stability, maintenance costs, and applicable scenarios. The following is a detailed summary of these differences:
The maintenance cycle of air compressors will vary depending on the equipment model, the use environment, the workload and the manufacturer's recommendations. Generally speaking, air compressors require regular daily inspections, preventive maintenance and regular maintenance to ensure their normal operation and
Coal mine air compressor must be explosion-proof. The reasons and specific requirements are as follows: 1. explosion-proof necessity: the particularity of coal mine environment There are a large amount of flammable and explosive substances such as gas and coal dust in the coal mine. When the concentration reaches the explosion limit, it will encounter ignition such as electric spark, high temperature or static electricity.
