OIL-COOLED SCREW COMPRESSOR SYSTEM AND METHOD FOR MODIFYING SAME

An oil-cooled screw compressor system is provided with: a first lubricating oil supply route which supplies lubricating oil to a screw section; and a second lubricating oil supply route which supplies lubricating oil to a bearing. The first lubricating oil supply route is provided with: a gas-liquid separator into which discharge gas from a screw compressor is introduced and which separates lubricating oil from the discharge gas; a first supply flow passage which is formed in a housing wall, is open to the outer surface of the housing wall, and is in communication with a screw chamber; and a first supply passage which is connected to the lubricating oil storage region of the gas-liquid separator and to the opening of the first supply flow passage. The second lubricating oil supply route is provided with: a lubricating oil storage tank; a second supply flow passage which is formed in the housing wall, is open to the outer surface of the housing wall, and is in communication with a bearing chamber; a second supply passage which is connected to the lubricating oil storage tank and to the opening of the second supply flow passage; a first discharge flow passage which is formed in the housing wall, is in communication with the bearing chamber, and is open to the outer surface of the housing wall; and a discharge passage connected to the lubricating oil storage tank and to the opening of the first discharge flow passage. Un sistema de compresor de tornillo refrigerado por aceite está provisto de: una primera ruta o trayectoria de suministro de aceite lubricante que suministra aceite lubricante a una sección de tornillo; y una segunda ruta o trayectoria de suministro de aceite lubricante que suministra aceite lubricante a un cojinete. La primera ruta o trayectoria de suministro de aceite lubricante está provista de: un separador de gas-líquido en el que el gas de descarga desde un compresor de tornillo se introduce y que separa el aceite lubricante desde el gas de descarga; un primer pasaje de flujo de suministro que está formado en una pared del alojamiento, está abierto a la superficie exterior de la pared del alojamiento, y está en comunicación con una cámara de tornillo; y un primer pasaje de suministro que está conectado a la región de almacenamiento de aceite lubricante del separador de gas-líquido y a la abertura del primer pasaje flujo de alimentación. La segunda ruta de suministro de aceite lubricante está provista de: un tanque de almacenamiento de acei
