Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen compressors, and in particular relates to a leakage-proof hydrogen compressor capable of staged pressurization. Background Art

[0002] The reciprocating piston compressor realizes the reciprocating motion of the piston through the pressure transmission of hydraulic oil. When the hydraulic oil is pumped into the piston cylinder by the high-pressure pump, the piston moves forward under the action of the hydraulic pressure to compress the hydrogen; when the electromagnetic reversing valve changes the flow direction of the hydraulic oil, the piston moves backward to perform the suction process, in which the reciprocating motion of the piston directly causes the change in the volume of hydrogen, completing the entire compression cycle.

[0003] For example, the patent document application number is 202320900163.X, which discloses a hydraulic piston hydrogen compressor, which consists of a cylinder, a first hydraulic cylinder, a second hydraulic cylinder and a hydraulic drive system. The cylinder, the first hydraulic cylinder and the second hydraulic cylinder are arranged horizontally and coaxially; the cylinder is located in the middle, which is a double-acting structure; the first and second hydraulic cylinders are located on the left and right sides of the cylinder, which is a single-acting structure. Pistons are provided in the cylinder, the first hydraulic cylinder and the second hydraulic cylinder, and the three pistons are fixed on the same piston rod. The cylinder is provided with a hydrogen inlet and a compressed hydrogen outlet; the first hydraulic cylinder and the second hydraulic cylinder are provided with a hydraulic oil inlet and outlet, and the hydraulic oil inlet and outlet are connected to the hydraulic drive system through a pipeline. The advantages of this utility model: compared with the traditional double-cylinder hydraulic piston hydrogen compressor for compressing high-purity hydrogen, the manufacturing cost is low and the operation is safe and reliable.

[0004] However, during the use of liquid-driven hydrogen compressors, the continuous reciprocating motion of the piston will generate a large amount of heat. Excessive heat will cause the seal to deform to a certain extent, making it difficult to ensure the sealing of the seal for a long time, thereby affecting the service life of the seal. Therefore, we need to propose a leak-proof hydrogen compressor with graded pressurization to solve the above-mentioned problems, so that it can effectively cool the piston barrel and improve the stability of the piston barrel during long-term use.

When the pressure of the gas discharged from the second compression cylinder 8 reaches the required pressure value, the solenoid valve 65 on the exhaust pipe 62 of the second monitoring component is opened to discharge the pressurized gas. If the pressure of the gas discharged from the second compression cylinder 8 does not reach the required pressure value, the solenoid valve 65 on the second connecting pipe 64 of the second discharge monitoring component 12 is opened to transfer the gas to the next compressor body for pressurization operation.
