GAS COMPRESSOR AND ABRASION STATE DETERMINING METHOD

摘要

A gas compressor of the present invention includes a reciprocating member, an accommodation portion, and a sealing portion, and the accommodation portion includes a compression chamber that compresses a gas and a non-compression chamber that is separated from the compression chamber by the reciprocating member and the sealing portion. Further, since the compression chamber includes a suction line that suctions a hydrogen gas, a discharge line that discharges a compressed gas, a connection line that is connected to the accommodation portion and is used so that at least a part of a gas flows therethrough when a gas passing through the sealing portion from the compression chamber exists, a flowmeter that is provided in the connection line, and a determination unit that determines whether a flow amount measured by the flowmeter is equal to or larger than a predetermined threshold value, it is possible to easily determine the abrasion state of the sealing portion.

主权项

1. A gas compressor, comprising:
a reciprocating member that moves in a reciprocating manner in the axial direction; an accommodation portion that accommodates the reciprocating member and includes a compression chamber compressing a gas by the reciprocating member and a non-compression chamber separated from the compression chamber; an annular sealing portion that is attached to one of the accommodation portion and the reciprocating member, the annular sealing portion separating the non-compression chamber from the compression chamber together with the reciprocating member; a suction line that suctions the gas into the compression chamber; a discharge line that discharges the gas compressed inside the compression chamber to the outside of the accommodation portion; a connection line that is connected to the accommodation portion and allows at least a part of a gas passing through the sealing portion from the compression chamber flow therethrough when the gas exists; a flowmeter that is provided in the connection line and measures a gas flow amount; and a determination unit that determines whether the gas flow amount measured by the flowmeter is equal to or larger than a predetermined threshold value.
