Abstract
The utility model discloses a compressor shaft seals structure, including compressor fuselage and compressor crankshaft, the compressor fuselage is provided with the fuselage end cover, the fuselage end cover is provided with the recess, be provided with subdivision formula oil blanket in the recess, subdivision formula oil blanket passes through the gland to be fixed in the recess of fuselage end cover, the seal lip laminating of subdivision formula oil blanket is in on compressor crankshaft's the anchor ring. The utility model discloses not only can satisfy the long -term reliable work of compressor, realize the quick replacement of oil blanket moreover, reduce because of the oil blanket leaks the production halts influence that accidental shutdown leads to, reduce user's loss that stops production.
Description
Technical field
This utility model belongs to compressor seal technical field, is specifically related to a kind of compressor shaft seal structure.
Background technology
Compressor is widely used in the fields such as oil, chemical industry, mine, stretches out the bent axle axle stretch end shaft coupling of compressor body
Device couples with driving arbor, thus realizes the driving of compressor.Bent axle stretches out and must be provided with oil sealing at fuselage in order to avoid outside lubricating oil
Leakage, traditional compressor crank shaft axle is stretched sealing structure and is used spiral gear oil groove and felt seal ring or the combination of integrated oil seal
Mode.For felt seal ring, can be able to be infiltrated by the lubricating oil in fuselage in During Process of Long-term Operation；When felt oil suction reaches full
With rear, lubricating oil will inevitably leak along bent axle, and poor and felt the replacement frequency of reliability is higher.For using entirety
The situation of formula oil sealing, when sealing ring lost efficacy and need to change, it is necessary to remove the shaft coupling even compressor between compressor and driving machine
Bent axle, also needs after the sealing ring more renewed reassemble the part of dismounting and re-start centering centering, and workload is big, the longest.
Utility model content
The purpose of this utility model is that provides a kind of compressor shaft seal structure to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of compressor shaft seal structure, including compressor body and compressor crank shaft, described compressor body arranges organic
Body end cap, described fuselage end cap is provided with groove, is provided with Split oil seal in described groove, and described Split oil seal is by pressure
Lid is fixed in the groove of described fuselage end cap, and the sealing lip of described Split oil seal is fitted in the anchor ring of described compressor crank shaft
On.
Further, described fuselage end cap and described Split oil seal are all enclosed within described compressor crank shaft.
Further, described gland is connected by screw and described fuselage end cap are fixing.
The beneficial effects of the utility model are:
This utility model not only can meet working reliably and with long-term of compressor, and achieves the quick-replaceable of oil sealing, subtracts
The little production interruption impact caused because of the shutdown of oil sealing leakage failure, reduces user's production suspension induced losses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing in Fig. 1 at I；
In figure: 1-compressor body, 2-fuselage end cap, 3-gland, 4-compressor crank shaft, 5-screw, 6-Split oil seal,
7-groove.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, this utility model includes compressor body 1 and compressor crank shaft 4, described compressor body 1
Being provided with fuselage end cap 2, described fuselage end cap 2 is provided with groove 7, is provided with Split oil seal 6 in described groove 7, described in cut open
Fraction oil sealing 6 is fixed in the groove 7 of described fuselage end cap 2 by gland 3, and the sealing lip of described Split oil seal 6 is fitted in
On the anchor ring of described compressor crank shaft 4.
Wherein said fuselage end cap 2 and described Split oil seal 6 are all enclosed within described compressor crank shaft 4.Described gland 3 leads to
Cross that screw 5 is fixing with described fuselage end cap 2 to be connected.
The oil seal replacement process of compressor shaft seal structure described in the utility model is as follows:
1) first unclamping screw 5, moving gland 3 to shaft coupling side to reserve installing space；
2) in groove 7, take out old Split oil seal 6, new Split oil seal 6 is pulled open from incision and is enclosed within pressure
On contracting machine crankshaft 4；
3) bonding agent is coated on the subdivision otch of Split oil seal 6, after bonding for oil sealing, be pressed into the recessed of fuselage end cap 2
In groove 7；
4) utilize gland 3 to press Split oil seal 6, and again screw 5 is fixed.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment, equivalent and the improvement etc. made within novel spirit and principle, should be included in guarantor of the present utility model
In the range of protecting.
