弁を備えた真空ポンプ用油分離器。 An oil tank in which exhaust gas from the vacuum pump is discharged to an internal upper space through a discharge pipe rising from the bottom, and oil mixed in the exhaust gas is separated and stored in the lower part;
An upper lid is installed above the oil tank and releases the exhaust gas from the oil tank interior upward from the outlet, and the main body of the vacuum pump is configured to discharge the oil stored in the oil tank from the bottom from the bottom. An overflow pipe is connected to the lower part of the oil tank to maintain the oil level at a predetermined level, and the upper end of the discharge pipe is placed in the oil tank at a distance from above. A double plate is installed to open and cover the exhaust pipe, and to receive the exhaust gas rising from the discharge pipe, change its direction, and collect the mixed oil in the form of oil droplets. A predetermined amount of nonflammable gas is introduced from the outside.
A nonflammable gas supply pipe for reducing the mixing ratio of explosive gas with air in the above-mentioned cavity to a safe range;
An oil separator for a vacuum pump, comprising a solenoid valve connected in the middle of the nonflammable gas supply pipe to periodically supply nonflammable gas.
