Embodiment

See Fig. 1, a kind of deaerator filter core of the utility model bottom oil return device, it comprises deaerator filter core 10 and deaerator cylindrical shell 9 and oil return pipe component 1, mounting hole 10-1 is had bottom deaerator filter core 10, the bottom of deaerator cylindrical shell 9 has mounting hole 9-1, oil return pipe component 1 is successively through the mounting hole of deaerator filter core 10, the mounting hole of deaerator cylindrical shell 9, locked by locking nut 3 between oil return pipe component 1 and deaerator filter core, be connected and fixed by ferrule fitting 5 between oil return pipe component 1 and deaerator cylindrical shell 9.

See Fig. 2, oil return pipe component 1 comprises return tube 1-1 and BULKHEAD UNION 1-2, BULKHEAD UNION 1-2 welded and installed is in a side end of return tube 1-1, BULKHEAD UNION 1-2 has spill port 1-2a, the spill port 1-2a outlet end of BULKHEAD UNION is provided with return tube mounting groove 1-2b, return tube 1-1 is assemblied in return tube mounting groove 1-2b and makes return tube 1-1 and spill port 1-2a UNICOM, and be welded to connect between return tube 1-1 and return tube mounting groove 1-2b, the spill port 1-2a entry end of BULKHEAD UNION 1-2 is provided with position limiting sealed plate 1-3;

BULKHEAD UNION 1-2 is also spacing by position limiting sealed plate 1-3 through the mounting hole of deaerator filter core 10, is locked between the BULKHEAD UNION 1-2 of oil return pipe component and deaerator filter core 10 by locking nut 3;

Position limiting sealed plate 1-3 bottom surface is sealing surface 1-3a, is tightly connected between the bottom surface of position limiting sealed plate 1-3 and deaerator filter core 10 by composite gland bush 2; The bottom surface size of position limiting sealed plate 1-3 and sealing surface size are determined by the diameter D1 of BULKHEAD UNION 1-2 and the diameter D2 of position limiting sealed plate 1-3, the size of adjustment sealing surface and oil filter bottom opening can realize the adjustment of return tube weldment rigging position, thus the error offset because processing and assembling produce, avoid the centering requirement of oil filter bottom opening and cylindrical shell mounting hole; The thickness H of position limiting sealed plate 1-3 and the thickness of composite gland bush 2 determine trapped fuel amount bottom deaerator filter core, therefore should be the smaller the better at the thickness of the situation lower control limit position sealing plate 1-3 ensureing structural strength.
