How to make air pump for refrigerator compressor
Among the hot topics in the past 10 days, DIY transformation and environmental protection reuse have become the focus of netizens' attention. Among them, the tutorial on transforming a used refrigerator compressor into an air pump is highly sought after. This article will introduce this transformation process in detail and attach relevant data for reference.
1. Principle of renovating air pumps for refrigerator compressors
The refrigerator compressor itself is a high-pressure gas pump that compresses the refrigerant through a motor drive piston. Its working principle is similar to that of an air pump. It only needs a little modification to realize the functions of inflation, painting, etc.
| Part Name | Original function | Renovated functions |
|---|---|---|
| Compressor body | Compressed refrigerant | Compressed air |
| Air inlet | Inhaled refrigerant | Inhale air |
| Air outlet | Exhaust high pressure refrigerant | Exhaust high-pressure air |
2. Materials required for transformation
| Material name | quantity | use |
|---|---|---|
| Waste refrigerator compressor | 1 | Main parts |
| barometer | 1 | Monitor pressure |
| Tracheal fitting | 2 | Connect the gas circuit |
| switch | 1 | Control power supply |
| Gas storage tank (optional) | 1 | Store compressed air |
3. Detailed explanation of the transformation steps
1.Safety preparation: Make sure that the compressor has been powered off and discharges residual refrigerant. It is recommended to operate in a well-ventilated environment.
2.Pipeline renovation: Remove the original refrigeration system pipeline connection to retain the compressor body. Connect the air inlet to the air filter and install the air pressure gauge and air pipe fittings on the air outlet.
3.Electrical connection: To connect the compressor motor to the power switch, it is recommended to use a circuit with overload protection.
4.Test run: Check whether all connections are firm before starting, and observe whether the pressure gauge reading is normal after starting.
| Test items | Normal value range | Exception handling |
|---|---|---|
| Work pressure | 0.5-1.0MPa | Check sealing | With the rapid development and widespread application of AI technology, discussions on AI regulation around the world are becoming increasingly hot. In the past month, many countries and regions have made important progress in AI legislation, showing different regulatory ideas and legislative rhythms. The following is an analysis of the latest progress in AI legislation in major countries and regions: 1. EU: The AI Act enters the final stage. The EU's Artificial Intelligence Act is currently in the final stage of the legislative process: - December 8, 2023: The EU Parliament, Council and Commission reach a political agreement - January 24, 2024: The EU Parliament Internal Market Committee and the Civil Liberties Committee pass the draft with an overwhelming majority - It is expected that April 2024: The EU Parliament's full vote is voting - It is expected from May to June 2024: The EU Council officially approved - It will be implemented in stages after taking effect. Some clauses may apply in 6 months. It will take 2-3 years to fully implement the bill. The bill adopts a risk-based hierarchical regulatory framework, which divides AI systems into four categories: unacceptable risks, high risks, limited risks and minimum risks. Key contents include: - Prohibiting certain AI applications (such as social scoring systems) - Implementing strict supervision of high-risk AI systems - Require basic models and general AI systems to comply with transparency obligations - Establishing a European AI office to be responsible for supervision 2. United States: State-level legislation is the first, federal policy promotes US AI legislation. The characteristics of state-level legislation are state-level and federal follow-up: State-level legislation: - Colorado: Consider AI bills - California: Multiple AI-related legislation is at the promotion of federal level: - October 30, 2023: President Biden signs the AI executive order - January 2024: Congress holds multiple AI hearings - Members of the two parties propose multiple AI-related bills. The United States adopts a relatively flexible regulatory approach, emphasizing the regulation of AI through existing legal frameworks (such as Consumer Protection Act, Civil Rights Act), while encouraging industry self-discipline. 3. China: Actively promote the construction of AI rule of law China adopts an active legislative attitude in AI regulation: - August 15, 2023: The Interim Measures for the Management of Generative Artificial Intelligence Services" Implementation - January 2024: The Cyberspace Administration of China and seven other departments jointly issued the "Implementation Opinions on Promoting Future Industrial Innovation and Development" - More comprehensive AI regulatory regulations are being formulated. China's regulatory priorities include: - Generative AI service filing system - Algorithm transparency requirements - Data security and personal information protection - Promote the integration of AI technology and the real economy 4 Other countries: - UK: Adopt "light-touch" supervision, not specifically legislate, but supervise AI through existing regulatory agencies - Canada: Promote the AI and Data Act (AIDA) - Japan: Release AI governance guidelines to balance innovation and supervision - South Korea: Formulate the AI Basic Law Framework Global AI legislation trend analysis: 1. Regulatory Framework: From the EU's comprehensive legislation to the US's industry self-discipline, form a regulatory intensity spectrum 2. Regulatory Focus: General focus on high-risk AI applications, basic models, generative AI3. Legislative Challenges: Balanced innovation and risk prevention and control, rapid technology iteration and legislative lag 4. International Cooperation: Major economies are strengthening international coordination of AI governance (such as discussions under the G7 and G20 frameworks) Future Outlook: - 2024 will become a key year for global AI regulation - EU AI Act may become a global benchmark - Regulatory differences among countries may lead to compliance complexity - Multinational enterprises will face challenges to adapt to different regulatory environments AI legislation process reflects the balance considerations between technological innovation and risk prevention and control in various countries. Enterprises should closely monitor the progress of relevant legislation, adjust compliance strategies in a timely manner, and participate in policy discussions to help form a reasonable regulatory framework. With the continuous development of AI technology, the global AI governance system will continue to evolve.
