HELIUM GAS COMPRESSING APPARATUS |
摘要 |
A helium gas compressing apparatus constructed in such as manner that: an oil separator in a high-pressure gas passage is connected to a low-pressure gas passage; and oil return path having first and second branch paths is provided between the high- and low-pressure gas passages; a capillary tube is installed in one of the two branch paths; and an adjustment valve is installed in the other branch path to adjust the pressure difference between the supply gas in the high-pressure gas passage and the return gas in the low-pressure gas passage. Because of this construction, the adjustment valve can be manipulated from outside to make fine adjustments on the pressure difference or change it to a desired value with ease even during operation of the apparatus, thereby adjusting the refrigerating capability of a helium refrigerating machine connected to the apparatus and the power consumption of the helium gas compressing apparatus. |
