Abstract
The utility model discloses a sealing mechanism of a turbocharger, the sealing mechanism comprises a sealing sleeve (4) which is tightly matched on a back board (1) through a sealing ring (3), wherein, the sealing sleeve (4) is provided with an oil thrower wheel (5), the oil thrower wheel (5) is positioned in a cavity (2) of the back board (1), and the outer surface of the oil thrower wheel (5) is shaped like a round table. As the oil thrower wheel is arranged on the sealing sleeve after adopting the structure, the leaked oil generates the centrifugal action along with the high-speed rotation of the sealing sleeve, thereby tearing a lubricating oil thin film and throwing out to a certain direction, avoiding the oil leakage of the turbocharger and further improving the working efficiency of a compressor.
Description
Technical field
The utility model relates to technical field of engines, specifically is a kind of sealing mechanism that is used for the turbosupercharger of motor.
Background technique
The machine that turbosupercharger is made up of turbine chamber and pressurized machine is actually a kind of air compressor, increases air inflow by pressurized air.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, and turbine drives coaxial impeller again, and the air that the impeller force feed is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, impeller just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor just can increase the output power of motor.When turbocharger operation, air is entered by intake duct, and under the effect of impeller blade, and then active wheel is made high speed rotating together, so air is compressed under action of centrifugal force.The air that flows out active wheel converts kinetic energy to the pressure energy by Diffuser, thereby improves gas pressure.And the sealing mechanism of turbosupercharger is the important step that guarantees its proper functioning, and it prevents that the lubricant oil of bearing from entering the circulation part of pressurized machine, and the combustion gas of the air of prevention gas compressor or whirlpool end enters the lubricant reservoir of pressurized machine.Sealing mechanism commonly used adopts the form of stuffing box gland, seals being provided with seal ring in the cooperation of backboard.There is following shortcoming in this sealing mechanism: when pulse pressure-charging, the combustion gas instantaneous pressure can reach very high value before the turbine, under turbine end and gas compressor end pressure balance destruction situation, is easy to take place leakage of oil, gas leak phenomenon like this.And after the pressurized machine generation leakage of oil, lubricant oil enters motor with the blower outlet air-flow can destroy the motor proper functioning.Meanwhile, a large amount of flow of lubricants make gas compressor play the effect of a part of oil pump through the impeller back, and a part of merit oil consumption is inhaled lubricant oil in pump, therefore can cause the reduction of compressor efficiency.
The model utility content
Technical problem to be solved in the utility model is that a kind of sealing mechanism that can avoid the turbosupercharger leakage of oil, improve the turbosupercharger of compressor efficiency is provided.
For solving the problems of the technologies described above, the sealing mechanism of a kind of turbosupercharger that the utility model provides comprises by seal ring being a tight fit in stuffing box gland on the backboard that described stuffing box gland is provided with disc, described disc is positioned at the cavity of backboard, and the outer surface of disc is a frustoconic shape.
After adopting above structure, the utility model compared with prior art, has following advantage: owing on stuffing box gland, be provided with disc, the centrifugal action that the oil that seepage is come produces at the high speed rotating along with stuffing box gland, the lubricant oil film is torn and thrown away with certain direction, reach the phenomenon of avoiding the turbosupercharger leakage of oil and produce, thus the working efficiency of raising gas compressor.
As improvement, described seal ring is twice, all with the backboard drive fit.After adopting double density seal sealing, more increased the sealing of sealing mechanism.
Description of drawings
Shown in the drawings is the sectional structure schematic representation of the sealing mechanism of the utility model turbosupercharger.
Wherein, 1, backboard; 2, cavity; 3, seal ring; 4, stuffing box gland; 5, disc.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the sectional structure schematic representation of the sealing mechanism of the utility model turbosupercharger shown in the drawings as can be known, the sealing mechanism of this turbosupercharger, comprise by seal ring 3 and be a tight fit in stuffing box gland 4 on the backboard 1, described stuffing box gland 4 is provided with disc 5, described disc 5 is positioned at the cavity 2 of backboard 1, and the outer surface of disc 5 is a frustoconic shape.Described seal ring 3 is twice, all with backboard 1 drive fit.
Claims (2)
1, a kind of sealing mechanism of turbosupercharger, comprise by seal ring (3) and be a tight fit in stuffing box gland (4) on the backboard (1), it is characterized in that: described stuffing box gland (4) is provided with disc (5), described disc (5) is positioned at the cavity (2) of backboard (1), and the outer surface of disc (5) is a frustoconic shape.
2, the sealing mechanism of turbosupercharger according to claim 1 is characterized in that: described seal ring (3) is twice, all with backboard (1) drive fit.
