Standards for oil-free compressors typically address multiple aspects, including performance, design, manufacturing, testing, and safety. These standards are designed to ensure that oil-free compressors can provide efficient and reliable compressed air without lubricant contamination. For the water-lubricated oil-free inverter screw air compressor of Shanghai Granklin Group, the following are some relevant standards and considerations:
performance criteria:
the quality of compressed air should meet relevant industry standards, such as ISO 8573-1. For oil-free compressors, Class 0 (oil-free) is usually required.
Compressors meet energy efficiency standards, such as the EU's Energy Efficiency Directive or China's energy efficiency labeling system.
Design and manufacturing standards:
the compressor should adopt oil-free lubrication technology, such as water lubrication, to ensure that no oil pollution is generated during the compression process.
The materials and components of the compressor shall comply with relevant standards, such as ASTM, DIN, etc., to ensure their strength and durability.
The electrical system of the compressor shall comply with electrical safety standards such as IEC or NFPA.
Test standard:
the compressor shall undergo strict performance tests before leaving the factory, including the flow rate, pressure, temperature and oil content of the compressed air.
The compressor should also undergo durability tests to verify its stability and reliability under long-term operation.
Safety standards:
compressors shall comply with relevant machinery safety standards such as ISO 12100 to ensure the safety of operators.
The control system of the compressor shall have safety functions such as overload protection and short circuit protection to prevent the danger caused by electrical failure.

In machining enterprises, compressed air, as a clean and efficient power source and process medium, is widely used in many production processes. The following are common equipment requiring compressed air in machining enterprises and their specific application scenarios: 1. pneumatic power equipment gas
Whether the air compressor needs to be refueled depends on the type of air compressor. When the reciprocating piston of the piston air compressor moves to the right in the cylinder, the pressure in the left cavity of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and outside air is sucked into the cylinder.
The maintenance cycle of the air compressor varies according to the usage and equipment model, but the following general maintenance rules can usually be followed: Daily maintenance: Check whether the pipeline is leaking. Check oil level, air filter element and coolant level. Easy to check
In pharmaceutical factories, clean compressed air is a key factor to ensure the safety, stable quality and compliance with regulatory requirements. Its role runs through all aspects of drug production, specifically reflected in the following aspects: 1. to prevent cross-contamination, to ensure the purity of drugs directly
The air compressor exhaust volume refers to the volume of air output from the exhaust end after the compressor is sucked and compressed from the intake end per unit time. It is an important technical parameter to measure the air supply capacity of the air compressor, usually in cubic meters per minute (m & sup3;/min) or cubic meters per hour (m & sup3;/h)
Whether the air compressor can always run depends on its type, working environment, load conditions, maintenance and other factors. For the screw air compressor, it can run continuously for a long time, even unattended for 24 hours. This type of air compressor in the air pressure is not
The maintenance cycle of the air compressor mainly depends on its frequency of use, working environment and the model and quality of the air compressor. Generally speaking, air compressors need regular maintenance to ensure their normal operation and extend their service life.
Air compressor, referred to as air compressor, has a wide range of applications and important role in the industrial field. The following are the main uses of air compressors in industry: 1. power supply Air compressors are the power source for many industrial pneumatic tools and equipment. It compresses air
The air compressor is indeed one of the main equipment of the power plant. It is responsible for key tasks such as soot blowing, gas supply for instruments, driving valves and tools, which directly affects the safety and efficiency of the power plant. The water-lubricated air compressor is becoming an increasingly popular solution in the power plant air supply system because it replaces oil with water, making the output air cleaner and easier to maintain.
In the paper industry, the role of air compressors is mainly reflected in the following aspects: Pneumatic control: Many operations of paper machines, such as paper conveying, positioning and cutting, require precise pneumatic control. Air compressors provide power for these pneumatic control systems.
