Abstract
The utility model belongs to air compressor machine technical field, and in particular to a kind of compressor drum bearing isolating seal structure.The compressor drum bearing isolating seal structure, including body, rotor transmission shaft, assembly end cap and end cover, the rotor transmission shaft, which is located at the assembly end cap of body, is equipped with assembling stand, the rotor transmission shaft extends to one end outside assembling stand equipped with bearing, and end cover is equipped with by fastening bolt, the side that bearing on the transmission shaft is located at assembling stand is equipped with sealing ring, and atmospheric chamber is equipped between sealing ring and assembling stand, and atmospheric chamber is connected to each leakage fluid dram that assembly side covers.The beneficial effect is that: structure is simple, makes to form partition-type sealing between bearing and body, when mechanical seal damages, the water of exudation is discharged by atmospheric chamber through leakage fluid dram, it avoids infiltration from impregnating the bearing of rotor transmission shaft end, prevents the transmission shaft bearing of rotor impaired, guarantee body normal use.
Description
Technical field
The utility model belongs to air compressor machine technical field, and in particular to a kind of compressor drum bearing isolating seal structure.
Background technique
Water jet compressor when in use, since internal body has water, if machine envelope it is poorly sealed or reach operating limit,
The intracorporal water of machine, which can ooze out, encounters bearing, be easy to cause the bearing of rotor impaired, influences body normal use.
Utility model content
A kind of in order to make up for the defects of the prior art, the utility model provides structures transmission shaft that is simple, preventing rotor
The compressor drum bearing isolating seal structure of bearing water inlet.
The utility model is achieved by the following technical solution:
A kind of compressor drum bearing isolating seal structure, including body, rotor transmission shaft, assembly end cap and sealed end
Lid, the rotor transmission shaft, which is located at the assembly end cap of body, is equipped with assembling stand, and the rotor transmission shaft extends to outside assembling stand
One end be equipped with bearing, and end cover is equipped with by fastening bolt, the bearing on the transmission shaft is located at the side of assembling stand
Equipped with sealing ring, atmospheric chamber is equipped between sealing ring and assembling stand, atmospheric chamber is connected to each leakage fluid dram that assembly side covers.
Further, the leakage fluid dram is located at atmospheric chamber two sides, and the level height of leakage fluid dram is lower than the level height of atmospheric chamber.
Further, the section exterior contour of the leakage fluid dram is zigzag.
Further, the transmission shaft, which is located at assembling stand, is equipped with mechanical seal.
The beneficial effects of the utility model are: structure is simple, make to form partition-type sealing between bearing and body, it is mechanical close
When envelope damage, the water of exudation is discharged by atmospheric chamber through leakage fluid dram, is avoided infiltration from impregnating the bearing of rotor transmission shaft end, is prevented
The transmission shaft bearing of rotor is impaired, guarantees body normal use.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the structural schematic diagram of the utility model.
In figure, 1 body, 2 assembly end caps, 3 rotor transmission shafts, 4 mechanical seals, 5 assembling stands, 6 end covers, 7 bearings, 8
Sealing ring, 9 atmospheric chambers, 10 leakage fluid drams.
Specific embodiment
A kind of 2 lutation dewatering structure of air compressor machine transmission shaft of the utility model is carried out furtherly below with reference to embodiment
It is bright.
Attached drawing 1 is a kind of specific embodiment of the utility model.A kind of compressor drum bearing 7 of the utility model is isolated close
Seal structure, including body 1, rotor transmission shaft 3, assembly end cap 2 and end cover 6, the rotor transmission shaft 3 are located at body 1
It assembles and is equipped with assembling stand 5 at end cap 2, the rotor transmission shaft 3 extends to one end outside assembling stand 5 equipped with bearing 7, and by tight
Fixing bolt is equipped with end cover 6, and the side that the bearing 7 on the transmission shaft is located at assembling stand 5 is equipped with sealing ring 8, sealing ring 8 and
Atmospheric chamber 9 is equipped between assembling stand 5, atmospheric chamber 9 is connected to each leakage fluid dram 10 on assembly end cap 2.
Further, the leakage fluid dram 10 is located at 9 two sides of atmospheric chamber, and the level height of leakage fluid dram 10 is lower than the water of atmospheric chamber 9
Flat height.
Further, the section exterior contour of the leakage fluid dram 10 is zigzag.
Further, the transmission shaft, which is located at assembling stand 5, is equipped with mechanical seal 4.
A kind of 7 isolating seal structure of compressor drum bearing of the utility model, when use when mechanical seal 4 is poorly sealed or
When impaired, the infiltration in body 1 is flowed into atmospheric chamber 9 after liquid exudation by being oozed out at mechanical seal 4 by assembling stand 5, and is led to
It crosses the leakage fluid dram 10 that is connected to atmospheric chamber 9 to be discharged, 9 two sides of atmospheric chamber are symmetrically arranged with leakage fluid dram 10, and sepage is from two when can be effectively
Side discharge is avoided impacting equipment operation, be protected so that the bearing 7 of water jet compression inboard rotor transmission shaft 3 be avoided to paddle
Demonstrate,prove 1 normal use of body.
The utility model is not limited to above embodiment, anyone, which should learn, makes under the enlightenment of the utility model
There is same or similar technical solution with the utility model, each fall within the protection scope of the utility model.
Technology that the utility model is not described in detail, shape, construction portion are well-known technique.
