[specific embodiment]
Below with reference to each attached drawing, invention is further described in detail.
Referring to Fig. 1 to Fig. 5, a kind of carbon ring seal system mixing sealing medium, applied to the equipment including compressor
On, the carbon ring seal system of the mixing sealing medium includes the axle sleeve 11 for being equipped with first axis central through hole (not shown), sets
There are the axle envelope set 12 of the second axial central through hole 129 and the carbocyclic ring 13 of at least five annulars, each carbocyclic ring 13 is designed with third axial direction
Central through hole 139, carbocyclic ring 13 are made of graphite, and carbocyclic ring 13 is also known as graphite-seal ring；12 inside of axle envelope set be equipped with
The annular seal space 121 of 13 equivalent amount of carbocyclic ring is designed with a carbocyclic ring 13 in each seal chamber 121;The axle sleeve 11
First axis central through hole be fixed in the shaft 99 of compressor, 129 He of the second axial central through hole of axle envelope set 12
The third axial central through hole 139 of each carbocyclic ring 13 is all sleeved on the axle sleeve 11, and axle envelope set 12 is fixed on the shell of compressor
In body (not shown), one end of the shaft 99 of the compressor is atmospheric pressure end, and the other end of the shaft 99 of the compressor is height
Working media end is pressed, in Fig. 1, Fig. 3 and Fig. 5, the left end of the shaft 99 of compressor is atmospheric pressure end, the shaft 99 of the compressor
Right end be high-pressure working medium end;The axle envelope set 12 is equipped with 14 He of radial air inlet pipeline for being passed through that sealing medium is air
Be passed through the radial water inlet line 15 that sealing medium is water, the radial air inlet pipeline 14 and radial water inlet line 15 all with the axis
Second axial central through hole 129 of big envelope 12 is connected；The radial air inlet pipeline 14 is close to atmospheric pressure end, and the radial direction
The seal chamber 121 there are two carbocyclic ring 13 is at least spaced between admission line 14 and atmospheric pressure end；The radial direction water inlet line 15 leans on
Nearly high-pressure working medium end, and between the radial water inlet line 15 and high-pressure working medium end at least between be separated with a carbocyclic ring
13 seal chamber 121；Carbocyclic ring 13 is close there are two being at least spaced between the radial air inlet pipeline 14 and radial water inlet line 15
Seal chamber 121；The inner circumferential surface of second axial central through hole 129 of the external peripheral surface of the axle sleeve 11 and axle envelope set 12
With the first radial clearance 19, that is to say, that the internal diameter of the second axial central through hole 129 of the axle envelope set 12 is greater than the axis
The outer diameter of set 11.The width C of the carbocyclic ring 132It is slightly less than the width C of the seal chamber 121 of the axle envelope set 121, the carbocyclic ring 13
Radial height D3It is slightly less than the radial height D of the seal chamber 121 of the axle envelope set 121, the third axial centre of the carbocyclic ring 13
The internal diameter D of through-hole 1392Slightly larger than the outer diameter of the axle sleeve 11, in fact, when work, it is each under the buoyancy of water or air
Carbocyclic ring 13 is to float in corresponding seal chamber 121；The third of the external peripheral surface of the axle sleeve 11 and each carbocyclic ring 13 is axial
The inner circumferential surface of central through hole 139 has the second radial clearance, and second radial clearance is less than the first radial clearance 19.
Carbon ring seal system of the present invention has used two kinds of sealing mediums, and a kind of sealing medium is water, from radial water inlet line
15 flow into, and another sealing medium is air, flow into from radial air inlet pipeline 14.When the shaft 99 of the compressor rotates, open
Open the valve for controlling the radial water inlet line 15, flow into water from the radial water inlet line 15, and adjust the radial direction into
The intake pressure of waterpipe 15, make it is equal into the pressure at the high-pressure working medium end of the shaft 99 of the pressure and compressor of water,
Due to entire carbon ring seal internal system structure bring resistance, it is now placed in the second axial central through hole 129 of axle envelope set 12
Pressure at the high-pressure working medium end for the shaft 99 that compressor should be slightly above close to the water pressure at high-pressure working medium end；With this
Meanwhile the valve for controlling the radial air inlet pipeline 14 is opened, flow into air from the radial air inlet pipeline 14, and adjust institute
The admission pressure for stating radial air inlet pipeline 14 is equal with the radial intake pressure of water inlet line 15, can guarantee air inlet in this way
With pressure balance of the water inlet between their carbocyclic ring, two arrows in Fig. 1, Fig. 3 and Fig. 5 are located relatively, that is, are located at
The about intermediate position of the first radial clearance 19 between the radial air inlet pipeline 14 and radial water inlet line 15, air and water phase
Meet, since pressure is equal, this everywhere in equilibrium state, so that water, gas amount of leakage is reached minimum；At this point, the radial direction water inlet pipe
Carbocyclic ring 13 between road 15 and high-pressure working medium end is enclosed under the buoyancy of water by water and floats, and the radial air inlet pipe
Each carbocyclic ring 13 between road 14 and atmospheric pressure end is enclosed under the buoyancy of air by air and floats；The radial air inlet pipeline
Each carbocyclic ring 13 between 14 and radial water inlet line 15, being surrounded close to the carbocyclic ring 13 of radial air inlet pipeline 14 by air is in air
Buoyancy under float, close to radial direction water inlet line 15 carbocyclic ring 13 by water encirclement be to float under the buoyancy of water.?
Under the mode of the carbon ring seal system, air not can enter high-pressure working medium end, can only leak from atmospheric pressure end, therefore will not
Cause the pressure change of carbon ring seal internal system；Water can only be leaked from high-pressure working medium end, and leakage will not pollute evaporation
The water quality of internal system.Simultaneously as inside compressor itself cooling can be water-cooled, therefore only need to adjust described in increase
The flow of radial water inlet line 15, makes the water to seal that can also cool for compressor, can save individual water cooling
Cooling simplifies operating procedure, has saved equipment cost.
