COMPRESSORS FOR NATURAL GAS AND RELATED DEVICES, SYSTEMS, AND METHODS

摘要

A natural gas compressor can include a pre-staging chamber that couples with a supply line to receive natural gas from the supply line. The compressor can additionally include a first-stage chamber that couples with the supply line to receive natural gas from the supply line. The first-stage chamber can additionally be coupled with the pre-staging chamber to receive from the pre-staging chamber natural gas that has been compressed by the pre-staging chamber. The compressor can also include a second-stage chamber configured to receive natural gas that has been compressed by the first-stage chamber.

1. A natural gas compressor assembly comprising:
a pre-staging chamber configured to be coupled to a supply line to receive natural gas from the supply line; a first-stage chamber configured to be coupled to the supply line to receive natural gas from the supply line and coupled with the pre-staging chamber to receive natural gas compressed by a first amount from the pre-staging chamber; a second-stage chamber configured to receive natural gas compressed by a second amount from the first-stage chamber; a a drive shaft; and a plurality of pistons coupled to the drive shaft, wherein the plurality of pistons are configured to alter sizes of each of the pre-staging, first-stage, and second-stage chambers as the drive shaft reciprocates in a first direction and in a second direction, wherein the pre-staging chamber and the second-stage chamber decrease in size and the first-stage chamber increases in size as the drive shaft moves in the first direction, and wherein the pre-staging chamber and the second-stage chamber increase in size and the first-stage chamber decreases in size as the drive shaft moves in the second direction.
