Oil-free air compressor is an air compressor that does not require lubricating oil and oil separation devices, and its working principle is to compress and discharge the air through an efficient filtration system and specially coated internal materials, thereby reducing environmental pollution and maintenance costs. In order to ensure the quality and performance of oil-free air compressors, acceptance needs to be carried out and corresponding acceptance standards formulated. The following is an example of the acceptance criteria for oil-free air compressors, including technical requirements, performance indicators, standards and other considerations.
1. Technical requirements
1.1 Oil-free air compressors should comply with relevant standards and regulations, and can meet user needs.
1.2 The device has a reasonable structure and is easy to install, debug and maintain.
1.3 The materials used should meet the requirements and have no harmful substances.
1.4 The equipment should have high working efficiency and reliability, and be able to run stably for a long time.
2. Performance indicators
2.1 Pressure range: The working pressure of oil-free air compressor should be within the specified range to meet the user's process requirements.
2.2 Exhaust flow: The exhaust flow of the oil-free air compressor should be able to meet the air consumption of the user, and remain stable under the rated load.
2.3 Compression ratio: The compression ratio of the oil-free air compressor should be within a reasonable range to avoid excessive compression ratio leading to overheating or failure of the equipment.
2.4 Noise: The noise of oil-free air compressor should meet the standard and not exceed the specified noise limit.
3. Stability criteria
3.1 Oil-free air compressors should have perfect protection measures, including overload protection, temperature protection, current protection and other functions.
3.2 The equipment should have good sealing performance to avoid leakage and prevent damage to the environment and operators.
3.3 The oil-free air compressor should be equipped with an emergency shutdown device, which can quickly cut off the power supply in an emergency to ensure the safety of the operator.
3.4 The electrical system of the device complies with relevant standards and is properly grounded to avoid dangers such as electric shock.
4. Detection method
4.1 The pressure, flow, temperature and other parameters of the oil-free air compressor should be tested by accurate testing instruments.
4.2 Noise and vibration are measured and compared with standards to ensure the reliability of the equipment.
4.3 Test the sealing performance of the equipment, and use the pressure tester and other equipment for leakage test to ensure that there is no leakage problem.
5. Acceptance documents
5.1 The acceptance documents of oil-free air compressors shall include equipment certificate, product manual, operation and maintenance manual, etc.
5.2 Acceptance documents record the device model, specifications, technical parameters, and performance indicators for easy reference and maintenance.
The above is an example of the acceptance standards for oil-free air compressors for reference. The actual acceptance standards should be formulated according to the specific product and industry requirements to ensure that the quality and performance of the equipment meet the needs and requirements of users. If necessary, it should also be improved with reference to relevant and industry standards and the opinions of technical personnel.
