Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and be not used in restriction the utility model.
The utility model provides a kind of feed water pump low voltage side oil catch and is provided with the feed water pump of this feed water pump low voltage side oil catch.Particularly, as shown in Figure 2, be the schematic diagram of the partial structurtes of the feed water pump of the utility model embodiment.
This feed water pump comprises feed pump shaft 21, bearing shell 22 and feed water pump low voltage side oil catch.Other structure of this feed water pump is identical with feedwater pump structure of the prior art, such as identical with other structure of DG150-100 × 6 type feed water pump, because feed water pump of the present utility model does not relate to the improvement of other structure, does not therefore repeat them here.Wherein, feed water pump low voltage side oil catch has following structure.This feed water pump low voltage side oil catch comprises the oil catch end cap 23 and flinger ring 24 with hollow structure.One end of this flinger ring 24 and one end close contact of oil catch end cap 23.In feed water pump, one end of oil catch end cap 23 is the one end near bearing shell 22.Flinger ring 24 and oil catch end cap 23 coaxial.The diameter of the inwall of flinger ring 24 is consistent with the diameter of the inwall of oil catch end cap 23.The inwall of oil catch end cap 23 is provided with groove 25, in groove 25, is filled with filler.With one end of the oil catch end cap 23 of one end close contact of flinger ring 24 there is stepped opening, the diameter of the opening of one end of oil catch end cap 23 is changed from small to big.One end of flinger ring 24 has protruding 241.The mating shapes of the shape of this projection 241 and the stepped opening of oil catch end cap 23, makes this projection 241 closely be embedded in the stepped opening of oil catch end cap 23.The external diameter of the other end 242 of flinger ring 24 is greater than the maximum internal diameter of the stepped opening of oil catch end cap 23, and a surface pressure of the other end 242 of flinger ring 24 is connected on the exterior edge face of one end of oil catch end cap 23.
The feed pump shaft 21 of feed water pump through oil catch end cap 23 and flinger ring 24, and passes the outer wall of feed pump shaft 21 and the inwall close contact of oil catch end cap 23 and flinger ring 24 of oil catch end cap 23 and flinger ring 24.
During use, the lubricant oil thrown away through bearing shell 22 is blocked by flinger ring 24 and flows back to grease chamber, solves from the problem of oil catch end cap 23 along feed pump shaft 21 leakage of oil.In above preferred embodiment, the structure of flinger ring 24, makes the sealing effect of flinger ring 24 best.
After flinger ring can make feed water pump stop, sealing is bad, therefore, in above preferred embodiment, end cap processes groove 25 and dose filler in groove 25, when feed water pump is stopped, filler can block excessive lubricant oil, makes grease chamber's oil level remain on normal level, thus solves the problem of feed water pump parking sealer.
9#, 4# and 5# feed water pump of DG150-100 × 6 type is carried out the transformation as feedwater pump structure of the present utility model, namely the structure of its feed water pump low voltage side oil catch is transformed.The sealing effect of improved feed water pump is good, solve the problem of feed water pump low voltage side oil catch leakage of oil, the normal operation of equipment can be ensured, extend the repair cycle of feed water pump, reach the object of labor intensity of economizing on the use of funds, reduce, economize on the use of funds 70,000 yuan year.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
