Description
Technical field
A kind of compensation hydraulic mechanism for dynamic seal ring is the utility model is related to, belongs to dynamic sealing compensation technique field.
Background technology
At present when dynamic seal ring and static sealing ring are coordinated, typically using giving dynamic seal ring one motive force, make
Dynamic sealing is fitted close with static sealing ring, the motive force that prior art uses, mainly based on spring-compensating, this compensation way
When in use, fail when spring is in a state for a long time, sometimes can also be produced because of the elastic force deficiency of spring sometimes
Lively sealing ring and static sealing ring cooperation are not in place, while are only found and big just will appreciate that when sewing.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than：There is provided a kind of for moving
The compensation hydraulic mechanism of sealing ring, its is simple in construction, can give one very stable balancing force of dynamic seal ring, and sustainability
By force.
Compensation hydraulic mechanism described in the utility model for dynamic seal ring, including vertical placement dynamic seal ring, are moved close
Seal right flank is the mating surface with static sealing ring, it is characterised in that：Ring type structure is vertically arranged with dynamic seal ring left surface
Cylinder body, the internal diameter of cylinder body is not less than the internal diameter of dynamic seal ring, the ring type structure of right-left seal cooperation is provided with cylinder body
Piston, piston are fixed by piston bush and dynamic seal ring left surface, and piston bush is with cylinder body in the cooperation that horizontally slips, a left side for piston bush
The right length haul distance maximum in cylinder body not less than piston, sets in oriented cylinder body on the cylinder body on the left of piston bush and carries out
The repairing pipeline of repairing, pressure gauge is provided with repairing pipeline.
Further, oil pump is connected with preferably described repairing pipeline, oil pump inlet is connected with fuel reserve tank by pipeline.To
Carry out refueling in cylinder body and be more convenient when compensating.
Further, filter is installed on preferably described repairing pipeline.The quality refueled in cylinder body is improved, it is effective to extend
Service life.
Compared with prior art, the utility model has the advantages that：
By the compensation hydraulic mechanism described in the utility model for dynamic seal ring, its is simple in construction, and this setting borrows
Cylinder body (is regarded cylinder body, piston bush regards piston rod by hydraulic cylinder works principles.), during installation, by dynamic seal ring and static seal
Circle carries out installation cooperation, then is added the oil of fuel reserve tank to the cylinder body on the left of piston by oil pump, is transported to the right so as to head on piston
It is dynamic, drive piston bush also to promote dynamic seal ring to the right, finally complete the tight fit of dynamic seal ring and static sealing ring, then to cylinder
Refueled in vivo, when the value on pressure gauge is 0.5MPa (pressure value can be depending on dynamic seal ring specification), stop adding
Oil, the pressure of pressure gauge need to be only observed at work, by pressure value it is known that the situation of dynamic seal ring, can give dynamic sealing
A very stable balancing force is enclosed, and sustainability is strong.
