Mechanical seal oil leakage prevention mechanism of the open-type compressor

摘要

(57) Abstract Objective Leaks from the mechanical seal the oil which flowThe fact that it arrives in the bearing of ntobosu can be obstructed securelyMechanical seal oil neutron leakage prevention of open die compressorFeature is offered. Constitution Penetrating completely the front boss of the housing, haujiOpen die ko which possesses the crankshaft which extends to ngu outsideIn mechanical seal oil neutron leakage prevention feature of npuretsusaBeing, the bearing and the mechanical seal of the front bossBetween extending forming the spiral channel on the surface of the crankshaft which is presentTo do, across barely interval from the surface of the crankshaft beforeTo provide the means which form the wall surface which encircles the description spiral channel, the aforementioned spiral shellfishAdjoining to the destal of the mechanical seal approaching of the rotation channel, the frontThe oil by-pass port is formed in the boss.
