Abstract
The utility model provides a high -speed MVR vapor compressor sealing device of single -stage, is by static piece, atmoseal, fast axis, fill the steam pipe, the baffle is constituteed, its characterized in that atmoseal has height difference, the different skewed tooth of incline direction to it has the air vent to open, through the gas pocket on static with fill the steam pipe intercommunication. The sealed position both ends of fast axis have incline direction two different skewed teeth, and all the other are flat tooth. The baffle is fixed on static, and has certain clearance between the seal. The utility model discloses simple structure, with low costs, sealed effectual, long service life.
Description
Technical field
This utility model relates to compressor seal technology, it is adaptable to the nucleus equipment single-stage high-speed MVR of MVR system steams
Vapour compressor.
Background technology
MVR itself is a high-efficiency energy-saving technology, and the height of its efficiency is to be determined by the efficiency of MVR vapour compression machine,
Single-stage high-speed compressor is the both vapor compression equipment that current efficiency is the highest.Additionally, the sealing effectiveness of compressor also determine MVR system
The efficiency of system, the bad meeting of sealing effectiveness admits air into MVR system, causes whole system efficiency to decline to a great extent.
Single-stage high-speed MVR vapour compression machine many employings gear-box speedup, can produce pressure-fired with oil temperature rising in gear-box
Mist of oil, and the water vapour of the internal high negative pressure often of compressor.Owing to there is huge pressure reduction between water vapour and mist of oil, therefore
Requirement to sealing is the highest, and the bad meeting of sealing effectiveness causes gear-box leakage of oil, is even drawn in compressor by mist of oil, produces
Pollute.Another kind of situation, compressor carries high positive pressure water steam, and when sealing effectiveness is bad, water vapour can blow in gear-box, makes
In obtaining lubricating oil, water content increases, and serious threat is to the safe operation of machinery.
At present, the single-stage high-speed MVR vapour compression machine of domestic employing relies primarily on import and domestic minority esbablished corporation.Enter
Mouth product mainly uses mechanical seal, although sealing effectiveness is preferable, but structure is complicated, cost high and easily breaks down.State
Interior product many employings labyrinth seal, though simple in construction sealing effectiveness is not ideal.
Utility model content
This utility model is intended to overcome above-mentioned technological deficiency, it is provided that a kind of simple in construction, low cost, good sealing effect, make
Sealing by life-span length.
For achieving the above object, the technical solution adopted in the utility model is: by static element, sealing gland, high speed shaft, fill steam
Pipe, baffle plate composition；The helical teeth that sealing gland is different with height, incline direction is different, and have passage, by static element
Pore connects with filling steam pipe.
Two ends, high speed shaft seal position are with different two helical teeth of incline direction, and remaining is flat tooth.Sealing gland and high speed shaft
Seal position and form two sections of stepped labyrinth sealings, and a cavity.When extraneous steam is filled with in cavity, isolation area can be formed,
Prevent steam inside from leaking outside, prevent the suction of mist of oil simultaneously.Baffle plate is fixed on static element, and has larger gap between sealing gland,
And have small gap between high speed shaft, therefore can pressure reduction between equilibrium vapor and mist of oil further, prevent mist of oil to be inhaled into
In compressor, or steam blows in gear-box.
Owing to using technique scheme, this utility model sealing effectiveness is preferable, its simple in construction, without consumable accessory, therefore,
Low cost, service life are long.
Accompanying drawing explanation
Fig. 1 is this utility model one single-stage high-speed MVR vapour compression machine schematic diagram of sealing device；
In the drawings: 1, static element；2, sealing gland；3, high speed shaft；4, steam pipe is filled；5, baffle plate；6, helical teeth；7, passage；8、
Pore；9, helical teeth；10, flat tooth；11, cavity.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings, not the restriction to its protection domain.
A kind of single-stage high-speed MVR vapour compression machine sealing device, is by static element (1), sealing gland (2), high speed shaft (3), fills
Steam pipe (4), baffle plate (5) form；Sealing gland (2) is killed by static element (1) clamping, fills steam pipe (4), baffle plate (5) all uses
Bolt is fastened on static element (1), its simple in construction, low cost.
The helical teeth (6) that sealing gland (2) is different with height, incline direction is different, and have passage (7), passage
(7) connected with filling steam pipe (4) by the pore (8) on static element (1).Its sealing two ends, position of high speed shaft (3) are with inclination
Two helical teeth (9) that direction is different, remaining is flat tooth (10).Sealing gland (2) and high speed shaft (3) seal position and form two sections of stage teeth
Labyrinth seal, and a cavity (11).When extraneous steam is filled with in cavity, isolation area can be formed, prevent steam inside from leaking outside, with
Time prevent the suction of mist of oil.
Baffle plate is fixed on static element, and the gap between baffle plate (5) and sealing gland (2) is 10 ~ 15mm, with high speed shaft (3) it
Between gap 0.2 ~ 0.5 mm.Can pressure reduction between equilibrium vapor and mist of oil further, prevent mist of oil to be inhaled in compressor,
Or steam blows in gear-box.
Therefore, this utility model one single-stage high-speed MVR vapour compression machine sealing device, it has simple in construction, cost
Low, good sealing effect, the feature of length in service life.
