Title:
LIQUID-FEED TYPE GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/181299
Kind Code:
A1
Abstract:
Provided is a liquid-feed type gas compressor capable of monitoring the liquid surface height inside a gas-liquid separator. The liquid-feed type gas compressor comprises: an oil separator that separates and stores oil from compressed air discharged from a compressor main body 1; a sampling pipe having the inlet side thereof connected at a prescribed height position of the oil separator and causing fluid to flow from the prescribed height of the oil separator as a result of the pressure difference between the inlet side and the outlet side thereof; a pressure sensor that detects the pressure of fluid that flows into or has flowed into the sampling pipe; a control device that determines whether the fluid that flows through the sampling pipe is oil or gas, by determining whether or not the pressure detected by the pressure sensor rises above a set value P1 or falls below a set value P2; and a notification device that makes notification of the determination results of the control device.
