Description

Technical Field

[0001] The present invention relates to a hydrogen compressor, in particular to a multi-cylinder linked hydrogen compressor. Background Art

[0002] It is known that hydrogen is a colorless gas that releases high heat when burned. The product of hydrogen combustion is water. Compared with current oil and gas energy sources, hydrogen does not produce solid waste and exhaust gas, nor does it pollute the environment. Since hydrogen itself is extremely light, it needs to be compressed multiple times to achieve volume concentration in order to facilitate the storage or transportation of hydrogen. The current hydrogen compressor drives the crankshaft to rotate through a motor and the connecting rod makes the piston reciprocate in the cylinder. The multi-stage compression movement formed by multiple pistons and cylinders enables hydrogen to be compressed multiple times. Most of the current hydrogen compressors are equipped with a motor power mechanism for each set of pistons and cylinders.

[0020] The multi-cylinder linkage hydrogen compressor of the present invention is implemented in combination with the attached Figures 1 to 6 First, the volumes of the first compression cylinder 5A, the second compression cylinder 5B, the third compression cylinder 5C, the fourth compression cylinder 5D, the fifth compression cylinder 5E and the sixth compression cylinder 5F gradually decrease. The method of using the present invention is that when the sliding wheel group of the piston rod 1 of the first compression cylinder 5A starts to move from the arc-shaped outer convex surface of the edge track 11 of the outer wave turntable 10 to the arc-shaped outer concave surface, the hydrogen gas source connected to the intake pipe 14 is sucked into the first compression cylinder 5A.
