Abstract
The utility model discloses a seal cartridge for the booster comprising a seal cartridge body secured on the rotor shaft of the booster, provided with a seal groove in the front and an antithrust bearing assembling slot at the end. The oil whipping holes A which are adequate distributed on the lateral section of the seal cartridge body, forming whipping vanes between the two adjacent whipping holes. The function of the utility model is that it can reduce the oil entering the seal ring effectively and improves the seal performance of the booster.
Description
Technical field
The utility model relates to a kind of stuffing box gland structure, relates in particular to a kind of pressurized machine stuffing box gland structure.
Background technique
Existing pressurized machine is because the motor practical use needs and application area constantly enlarges, for example be equipped with the bus of boosting type motor, the harbour container trailer, vehicles such as plateau purposes, idling, the anxious acceleration, other variable parameter operation is chronic, factors such as plateau operation degree of vacuum increase cause the pressurized machine oil leak, the machine oil that leaks enters air inlet tube, intercooler, motor, the long-pending oil of intercooler stops up air cavity can't proper functioning, machine oil enters and produces burn oil in the cylinder, influence normal combustion, cause engine emission to worsen and the oil consumption increase, and booster performance decline, can cause pressurized machine to damage or cisco unity malfunction when serious.
Summary of the invention
The technical problems to be solved in the utility model is the defective that overcomes prior art, and a kind of stuffing box gland that can effectively avoid the pressurized machine oil leak is provided.
The utility model pressurized machine stuffing box gland, comprise the stuffing box gland body that is arranged on the supercharger rotor axle, front end at the stuffing box gland body is provided with the seal ring annular groove, the rear end of stuffing box gland is provided with the thrust bearing mounting groove, on the cross section in the neutral position of described stuffing box gland body, be provided with and get rid of oilhole A, the described oilhole A that gets rid of is along circumferentially evenly arranging, gets rid of to form between oilhole A at adjacent two and gets rid of oily blade.On described stuffing box gland body, also be provided with become certain angle of inclination with the rotor shaft axial direction get rid of oilhole B.
As a kind of improvement of the present utility model, the described oilhole A that gets rid of is cylindrical, and its center line is vertical with the rotor shaft center line or become certain angle of inclination.Described angle of inclination is 0 °～90 °
As another kind of improvement the of the present utility model, described stuffing box gland is the stepped cylindrical structural of metal.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, simple in structure;
2, effectively reduce the lubricant oil that enters the seal ring position, improved the sealability of pressurized machine.
Description of drawings
Pressurized machine stuffing box gland structure of the present utility model is such:
Fig. 1 is first kind of stuffing box gland structure sectional view;
Fig. 2 is second kind of stuffing box gland structure sectional view;
Fig. 3 is the third stuffing box gland structure sectional view;
Fig. 4 is the 4th a kind of stuffing box gland structure sectional view;
Among Fig. 1～Fig. 4,1-gets rid of oilhole B, 2-and gets rid of that oilhole A, 3-seal ring annular groove, 4-thrust bearing mounting groove, 5-rotor shaft mounting hole, 6-get rid of oil groove, 7-gets rid of oily blade, 8-stuffing box gland body.
Embodiment
With reference to Fig. 1～shown in Figure 4, the utility model is a kind of pressurized machine stuffing box gland, and its structure comprises: stuffing box gland body 8, get rid of oilhole 1,2, get rid of oily blade 7, seal ring annular groove 3, thrust bearing mounting groove 4, rotor shaft mounting hole 5.
Stuffing box gland body 8 is arranged on the supercharger rotor axle, front end at stuffing box gland body 8 is provided with seal ring annular groove 3, the rear end of stuffing box gland is provided with thrust bearing mounting groove 4, on the cross section in the neutral position of described stuffing box gland body 8, be provided with and get rid of oilhole A2, the described center line that gets rid of oilhole A2 is vertical with the rotor shaft center line and along circumferentially evenly arranging, gets rid of to form between oilhole A and gets rid of oily blade 7 at described adjacent two.On described stuffing box gland body, also be provided with become certain angle of inclination with the rotor shaft axial direction get rid of oilhole B1.Described angle of inclination is 0 °～90 °
It is cylindrical getting rid of oilhole A, and its center line is vertical with the rotor shaft center line or become certain angle of inclination.Stuffing box gland is the stepped cylindrical structural of metal.
In use, stuffing box gland body 8 and rotor shaft are assembled together and turn clockwise with rotor high-speed, arrive after the parts of lubricating oil of lubricated thrust bearing is come out and get rid of oilhole 1,2 or get rid of oil groove 6 positions, stuffing box gland is along with rotor high-speed rotates, and lubricant oil rotates thereupon, because of centrifugal action lubricant oil is got rid of oilhole 1 from stuffing box gland, 2 or get rid of oil groove 6 and throw away, cause leaking thereby avoided too much lubricant oil to enter the seal ring position.The lubricant oil at stuffing box gland position is existing to rotatablely move and has centrifugal motion, many groups to get rid of oilhole 1,2, gets rid of the oil effect of getting rid of that oily blade 7 structures have been strengthened stuffing box gland; Get rid of oilhole 1,2 or get rid of the movement locus that oily blade 7 inclination several angles had both catered to lubricant oil in the stuffing box gland, improved and got rid of the oil effect, play oil-blocking action simultaneously again, can avoid too much lubricant oil to enter the seal ring position, thereby improve the sealability of pressurized machine through stuffing box gland.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
