The "per square centimeter" representation of air compressor pressure (kgf/cm²) is a commonly used pressure unit in Asia, and the conversion relationship with the legal unit of measurement bar is as follows:
or
bar=kgf/cm²×0.9807| bar | kgf/cm² | application Scenarios |
|---|---|---|
| 1 bar | 1.02 | instrument gas and low pressure equipment |
| 3 bar | 3.06 | spraying equipment, small pneumatic tools |
| 5 bar | 5.10 | pharmaceutical cleanroom, medium power tools |
| 7 bar | 7.14 | bottle blowing machine, high pressure cleaning equipment |
| 10 bar | 10.20 | mine rock drill, special process |
if the air compressor pressure is 7 bar:
7×1.0197≈7.14kgf/cm²
if 5 kgf/cm² is required:
5 ÷ 1.0197 & asymp;4.9bar (air compressor pressure to be set)
Note: In practical engineering, it is recommended to use bar or MPa(1 MPa = 10 bar) uniformly to avoid confusion.
For equipment with large air output, multiple factors need to be considered when selecting an air compressor to ensure that the demand is met. The following are some recommended air compressor types and characteristics: Screw air compressor: Screw air compressor because of its efficient, reliable and smooth operating characteristics
In many aspects of modern industrial production, screw air compressor as the key equipment of gas compression and power transmission, its performance stability and technical advancement play an important role in ensuring production efficiency and product quality. In many air compressor brands
The operating range of equipment compressed air pressure fluctuations usually varies according to specific equipment and application scenarios. Generally speaking, the normal working pressure range of compressed air has a certain standard, but it may also be adjusted due to the specific needs of industrial equipment and processes.
Air compressor with water is a common problem, which may affect the quality of compressed air and the normal operation of equipment. The following is the general method to deal with the water in the air compressor: check and exclude the external water source: make sure that the air inlet of the air compressor is not covered by rainwater or its
Answer: The first warranty of the air compressor usually requires the replacement of the oil (also known as the lubricating oil) and the oil filter. The oil filter should be replaced after 800 hours of first operation. It is better to add screw oil before installing the new filter element and seal the filter element.
No matter what kind of equipment of the air compressor, it is inevitable that there will be failures in the operation process, and so will the variable frequency air compressor. The following is a summary of some failures and solutions that often occur in the factory during the operation of the variable frequency air compressor. 1. Unstable voltage
Today, with the rapid development of air compressor technology, Shanghai Granklin Group has brought revolutionary changes to the bottle blowing industry with its water lubricated screw air compressor products. This innovation not only improves production efficiency, but also significantly reduces operating costs, becoming the industry's
In the foundry industry, air compressors are widely used in various technological processes to power casting equipment or to generate compressed air to complete specific tasks. The following are some specific applications of air compressors in the foundry industry: Pneumatic tools and equipment: foundries often make
A pressure of 13kg can be converted to 1.3MPa (megapascals). Since the pressure of 1kg is equal to 0.1MPa, the pressure of 13kg is equal to 13 x 0.1MPa = 1.3MPa. In physics, pressure refers to the vertical force on a unit area, using the formula P = F/S table
The maximum pressure resistance value of the factory air source pressure gauge varies depending on the application scenario, medium type and industry specifications. The following is a specific analysis: 1. common pressure resistance range compressed air system: general standard: the maximum pressure resistance of the compressed air pressure gauge in the factory is usually
