Preferably, the seal section is a hollow cylinder, and the outer diameter of the seal section is larger than the outer diameter of the process tube.
Through the restriction the external diameter of seal segment is guaranteed the seal segment can block up the technology pipe tube hole, because the seal segment with can't laminate completely between the technology pipe, the seal segment with the gap that leaves between the technology pipe with the groove of disappointing constitutes airflow channel jointly, plays the reduction the inside atmospheric pressure's of totally enclosed compressor effect.
Preferably, an oil delivery pipe is arranged in the oil injection gun head, and the oil outlet is communicated with the oil inlet through the oil delivery pipe.
And oil enters the oil injection gun head through the oil inlet and flows into the totally enclosed compressor from the oil outlet after flowing through the oil conveying pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) The utility model provides a let out the gas tank and can derive the inside gas of totally enclosed compressor to the external world, at the in-process of totally enclosed compressor oiling, the totally enclosed compressor is extruded with gas from the groove of disappointing to the oil that flows in totally enclosed compressor fast, reduces the inside atmospheric pressure of totally enclosed compressor, avoids oil to receive gas hindrance from reverse blowout in the technology pipe.
(2) The utility model provides a cooperation section and technology pipe tube hole clearance fit, when inserting the oil gun head into the technology pipe, can utilize the cooperation section to inspect whether the technology pipe warp, if the cooperation section can insert the technology pipe smoothly then can prove that the technology pipe does not warp at the in-process of production.
