Abstract
Disclosed is a booster air pump end sealing element, which relates to a diesel engine booster. The technical proposal provided according to the utility model is that a ring lug boss is formed in the center of a seal ring, a ring groove is formed in the body of the boss and the seal ring, a plurality of radial through-holes are uniformly provided along the circumferential direction on the boss portion, which is characterized in that a plurality of radial slots are uniformly added on the boss, the slot end portion is formed in the inner face of the ring groove. The utility model opens the slots uniformly on the periphery orientation of the seal ring supporting, and parts of the fluid oil is kicked off by the rotating centrifugal effort, thereby the fluid oil leakage can be avoided.
Description
Technical field
The utility model relates to the pressurized machine on a kind of diesel engine, specifically a kind of Sealing that is used on the pressurized machine.
Background technique
Along with country is more and more stricter to the requirement of vehicular emission standards, vehicular engine must could satisfy the Abgasgesetz of current and expected future by the configuration exhaust-gas turbocharger.Yet the oil leak of control supercharger air compressor end is key subjects of puzzlement pressurized machine industry always, because oil leak directly influences the economy and the emission performance of motor, so people seek the leakage that the whole bag of tricks reduces lubricant oil.
The motor that exhaust-gas turbocharger is installed is when declared working condition is worked, the rotor part rotational speed of pressurized machine will be changeed up to per minute tens0000, rotor part is under so high rotating speed, require gas compressor end sealed member that very high intensity and wear-resisting property will be arranged, and its structural design should make the motion of liquid medium meet artificer's requirement.
Currently used design proposal is: after seal ring 2 and seal ring supporting 3 assemblings, seal ring 2 is stuck in the mesopore of sealing gland cover plate 1, and to its axially locating, seal ring supports 3 relative force bearings, 4 high speed rotating by thrust-bearing 4.Seal ring 2 and labyrinth seal structure have stoped most of lubricant oil to air leakage, but because assembling needs, and seal ring 2 must leave opening, therefore still have parts of lubricating oil to go out to air leakage by the opening of labyrinth structure and seal ring 2.For this reason, there is the people on the circumferencial direction of seal ring supporting 3, evenly to get through hole, this part lubricant oil is thrown away towards periphery by the centrifugal force that rotation produces.But because the through-hole structure design of above-mentioned seal ring supporting 3 is reasonable inadequately, so the gas compressor end through regular meeting the situation that lubricant oil leaks from seal ring takes place on every side.
Summary of the invention
The purpose of this utility model is to design a kind of supercharger air compressor end sealed member, evenly gets slotted hole again on the circumferencial direction of seal ring supporting, a part of lubricant oil is thrown away towards periphery, to avoid the problem of oil leak by the centrifugal force that rotation produces.
According to design proposal provided by the utility model, form the tongue of the projection of annular at the middle part of seal ring, between the body of tongue and seal ring, form circular groove, several through holes radially circumferentially are set equably in the tongue upper edge, it is characterized in that: increase several slotted holes radially on tongue more equably, the end of this slotted hole has part to be formed on the interior edge face of circular groove.
Be provided for installing the mounting groove of seal ring in seal ring supporting left side, flange be set, in the seal ring supporting in flange left side, form the mounting groove of thrust-bearing on the right side of seal ring supporting.The sealing gland cover plate is installed in left side in the seal ring supporting, and the belt projection of sealing gland cover plate embeds in the circular groove, and at the embedded seal ring of mounting groove, the sealing ring is between sealing gland cover plate and seal ring supporting.Installed thrust bearing in the mounting groove on seal ring supporting right side is provided with grease channel on thrust-bearing, installation shaft in the through hole of seal ring supporting central authorities.
The utility model has carried out redesign and flow field analysis at the shortcoming of original structure to the structure of kernel component seal ring supporting 3.It is identical with mounting type with original structure to improve structure, is core part with seal ring supporting 3 all, and parts such as gentle capping plate 1, seal ring 2, thrust-bearing 4 are formed supercharger air compressor end sealed member jointly.In this patent, the improvement of seal ring supporting 3 design is mainly reflected in: prior art is only evenly got through hole 6 at the circumferencial direction of the tongue 7 of projection, and this mode only plays the oil effect of getting rid of.Compared with prior art, the utility model is evenly got through at circumferencial direction on the basis in hole 6, has increased by a platoon leader hole 8 again, and the tongue 7 that seal ring supports 3 projectioies is passed in this platoon leader hole 8, and has part to beat on the main body of seal ring supporting 3.By to the flow field analysis of lubricant oil under the high speed and high pressure difference, a newly-designed platoon leader hole 8 makes seal ring supporting 3 under the requirement of satisfying intensity, reaches the purpose of prevention oil leak.Comparative trial confirms that the sealing structure effect after the improvement is very obvious, has avoided lubricant oil to leak to the gas compressor end.

Embodiment
Sealing gland cover plate 1, seal ring 2, seal ring supporting 3, thrust-bearing 4, axle 5, through hole 6, tongue 7, slotted hole 8, circular groove 9, part is formed at the end 10 of the slotted hole 8 on the interior edge face of circular groove 9, the mounting groove 11 of thrust-bearing 4, end flange 12, the mounting groove 13 of seal ring 2, oil leab 14.
As shown in the figure: the tongue 7 that forms the projection of annular at the middle part of seal ring 3, between the body of tongue 7 and seal ring 3, form circular groove 9, several through holes 6 radially circumferentially are set equably in tongue 7 upper edges, increase several slotted holes 8 radially on tongue 7 more equably, the end 10 of this slotted hole 8 has part to be formed on the interior edge face of circular groove 9.Support the mounting groove 13 that 3 left sides are provided for installing seal ring 2 at seal ring, flange 12 is set, in the seal ring supporting 3 in flange 12 left sides, form the mounting groove 11 of thrust-bearing 4 on the right side of seal ring supporting 3.Sealing gland cover plate 1 is installed in left side in seal ring supporting 3, and the belt projection of sealing gland cover plate 1 embeds in the circular groove 9, and at mounting groove 13 embedded seal rings 2, sealing ring 2 is between sealing gland cover plate 1 and seal ring supporting 3.Installed thrust bearing 4 in seal ring supports the mounting groove 11 on 3 right sides is provided with grease channel 14 on thrust-bearing 4, installation shaft 5 in seal ring supports the through hole of 3 central authorities.
The utility model is evenly got through at circumferencial direction on the basis in hole 6, has increased by a platoon leader hole 8 again, and the tongue 7 that seal ring supports 3 projectioies is passed in this platoon leader hole 8, and has part to beat on the main body of seal ring supporting 3.By to the flow field analysis of lubricant oil under the high speed and high pressure difference, a newly-designed platoon leader hole 8 makes seal ring supporting 3 under the requirement of satisfying intensity, reaches the purpose of prevention oil leak.Comparative trial confirms that the sealing structure effect after the improvement is very obvious, has avoided lubricant oil to leak to the gas compressor end.
