Title:
COOLING DEVICE FOR VACCUM-ORIENTED MULTI-STAGE TYPE ROOTS BLOWER
Document Type and Number:
Japanese Patent JPS6245992
Kind Code:
A
Abstract:

PURPOSE: To facilitate the cooling by connecting an outlet of a first-stage vaccum-oriented Roots blower and an inlet port of a last-stage blower by means of a heat-exchanging flexible hose soaked in the water, thereby soaking the blower into the cooling water.

CONSTITUTION: A flexible hose 21 is connected to an inlet port 17a of a vaccum- oriented Roots blower 17 at the last stage, while a flexible hose 18 is connected to an outlet port 15b of a blower 15 at the first stage. The cooling water W, which is supplied to a cooling box 1 through a supply pipe 10 and is discharged from a drain pipe 11, is prepared in such a manner that its level is above all the blowers 15W17 and flexible hoses 18W21. With this contrivance, the cooling work can be carried out efficiently without using a large-scale refrigeration cycle equipment.
