What's the difference between high-pressure pump and ordinary one?

The difference between pumping principle and air intake.

1, inflation difference principle: the high-pressure pump uses steam power to compress the sealed air into high-pressure gas. External energy is needed to generate steam power. Ordinary pumps compress air by mechanical means to achieve the purpose of pumping air without external energy.

2. Difference of air intake: The high-pressure pump has a large air intake, which can compress a large amount of air into high-pressure gas in a short time, and is suitable for applications requiring high-pressure gas, such as industrial equipment. Ordinary pump has a small air intake and is suitable for inflating household items such as bicycles, automobile tires and inflatable balls.
