Provided is a reciprocating compressor including a third-stage compression unit, a fifth-stage compression unit, a drive unit, a discharge mechanism, a pressure sensor, and a discharge control unit. The discharge mechanism is capable of discharging hydrogen gas from a second connection pipe that allows hydrogen gas to flow to be suctioned into the third-stage compression unit. The discharge control unit controls the discharge mechanism to discharge the hydrogen gas from the second connection pipe when pressure of the hydrogen gas detected by the pressure sensor is higher than a set value preset.

Reciprocating compressor

A compression device () includes compression portions, a suction line, connection lines, a discharge line, and display portions (d) configured to display pressure values, pressure gauges (PGto PG) provided for at least one of the suction line, the connection lines, and the discharge line and a housing (). The housing () includes a peripheral wall () and a door (). The pressure gauges (PGto PG) are situated at positions to face the door ().

Compression device

The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

Compressing device and method for carrying out compressing device

A gas supplying apparatus includes a compressor, a housing having an exhaust port, and an exhaust duct. The housing has a circumferential wall and a top wall. The circumferential wall has an access section. The exhaust port is provided on at least one of the circumferential wall and the top wall at a location higher than the access section. The exhaust duct includes a discharge port for discharging the air, exhausted from the exhaust port, to the outside. The discharge port is opened upward or opened downward in an area overlapping the top wall in an up-and-down direction.

Gas supplying apparatus

A combustible gas supply unit includes a high pressure gas facility for handling combustible gas which is compressed and a housing provided with a high pressure gas handling area containing the high pressure gas facility. The housing has a portion that is disposed in a side close to a boundary between premises of a hydrogen station and an outer region of the premises and constitutes the high pressure gas handling area, the portion being substantially composed of a partitioning wall member that resists an impact of an explosion of combustible gas.

Combustible gas supply unit and hydrogen station

A combustible gas supply unit is for supplying compressed combustible gas to a dispenser. The combustible gas supply unit includes a high pressure gas facility for handling compressed combustible gas, a base plate having the high pressure gas facility installed thereon and a barrier supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility. A barrier is shaped to surround at least a part of an outer periphery of the high pressure gas facility and includes a part to be supported by a base plate having the high pressure gas facility installed thereon.

Combustible gas supply unit and barrier

[Object] To enable a gas supply system to be easily transported and to increase a degree of freedom when the gas supply system is installed. [Solution] A hydrogen station includes: a filling facility for filling a tank-mounted device with a gas; and a gas supply system for supplying the gas to the filling facility. The gas supply system includes: a compressor for compressing the gas; a compressor accommodating body for accommodating the compressor; a refrigerator for cooling the gas flowed into the filling facility or the gas just before being flowed into the filling facility, the refrigerator including an evaporation part, an expansion part, and a compression part; and a cooler accommodating body for accommodating the evaporation part, the expansion part, and the compression part. The compressor accommodating body and the cooler accommodating body are detachable from each other.
