Ultra-low temperature refrigerant charging machine
Product Description
The refrigeration temperature of ultra-low temperature refrigerants can reach below -80°C. It is mainly used in ultra-low temperature equipment such as environmental test chambers, ultra-low temperature freezers, and blood bank refrigerators. R170 and R508b are currently the mainstream ultra-low temperature environmentally friendly refrigerants. Due to the low critical temperature of ultra-low temperature refrigerant, its charging mode is different from that of conventional refrigerants. With years of technology accumulation and continuous breakthroughs and innovations, HJ took the lead in launching an ultra-low temperature refrigerant filling machine with a filling accuracy of 100g≤±1g, which greatly improved Improved filling accuracy.
Test items
Filling accuracy detection:
Verify the filling accuracy of the filling machine under ultra-low temperature conditions to ensure that the refrigerant filling amount meets the preset standards.
Through multiple repeated tests, the stability and consistency of filling accuracy are evaluated.
Refrigeration performance testing:
Test the refrigeration effect of the filling machine in ultra-low temperature environment, including refrigeration speed, temperature stability, etc.
Verify that the filling machine is able to fill the refrigerant to the target temperature within the specified time.
Electrical safety testing:
Check whether the electrical system of the filling machine complies with relevant safety standards, including protective measures against electric shock and fire.
Conduct voltage and insulation tests on electrical components to ensure the reliability of the electrical system.
Explosion-proof performance testing:
Given that ultra-low temperature refrigerants may have flammable or explosive properties, it is crucial to test the explosion-proof performance of the filling machine.
Conduct explosion-proof testing to verify the safety of the filling machine in potentially explosive environments.
Mechanical performance testing:
Evaluate the mechanical structural strength and stability of the filling machine, including the wear resistance and corrosion resistance of key components.
The moving parts of the dispensing machine are tested for flexibility and reliability.
