はカーボン化して油に共にセパレータ３に吐出される。Figure 1 shows the system of a conventional screw fluid machine. The fluid sucked through the suction throttle valve 1 is compressed by the compressor 2 and then discharged to the separator 3 together with the compressed oil. When compressed by this compressor 2, a large amount of heat is generated and the mixed oil is oxidized and deteriorated. When the oil deteriorates due to oxidation, a part of it becomes carbonized and is discharged to the separator 3 along with the oil.

維状のフィルタ８の部分に堆積する。Since the oil separated by the oil separator element is a liquid, it gradually travels below the element and is discharged outside the oil separator element, but since carbon is solid, it is deposited on the fibrous filter 8 portion.

を大きくしている。If you use it for a long time, the amount of carbon deposits will increase,
In addition to the heat storage effect of this carbon, spontaneous combustion may occur in the oil separator element. Since it is not possible to limit the location where this spontaneous combustion occurs, protective equipment is not appropriate and the damage is increased.

生するようインターロックを取る。Figure 3 shows a fibrous filter 8 of an oil separator element in which a molten material 9, such as optical fiber glass, which melts at low temperatures is rolled up. Wrap it in a spiral. The position where it is wound is the outlet side of the fluid flow in the oil separator element 8, and also serves as an interlock in the thickness direction of the oil separator element. A light source 10 is placed at one end of the optical fiber glass 9, and a photodetector 11 is placed at the other end so that if the optical fiber glass 9 is heated and breaks somewhere, the photodetector 11 will no longer be able to detect light. . When no light is detected by the photodetector 11, an interlock is provided to stop the fluid machine or issue an alarm.

For example, it is possible to use a material (metal) used in a temperature fuse. can. When using a metal material in this way, an electric current is passed through the molten material. When the molten material melts due to ignition, the current is cut off, which allows ignition to be detected. If a molten metal is used, it is desirable to avoid contact with the metal part of the oil filter element at two or more places.
