Description
Technical field
The utility model relates to spraying machine fields, and in particular to a kind of plunger bushing.
Background technique
Existing spraying machine mostly uses cylinder chamber greatly to achieve the purpose that water suction, but existing cylinder chamber is prolonged
It under use, is easy to produce staff and forgets the problem of adding lubricating oil, be easy so as to cause plunger and plunger bushing because of lubrication
Not enough lead to the abrasion of plunger and plunger bushing, so as to cause sealing effect variation, so that the soaking effect of cylinder chamber is bad, because
This is needed using powerful motor so that spraying machine reaches need of work, wastes the energy.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of sums that lubricity is high to be not easy to grind
The plunger bushing of damage.
To achieve the above object, the utility model provides following technical solution: including first close including body, on body
Sealing groove and the second seal groove, the first seal groove and the second seal groove are equipped with sealing ring, also set lock chamber on body, in lock chamber
Equipped with lubrication management, self-lubricating layer is covered on lubrication management.
Further, lubrication management includes the first cylindrical lubrication management and the second lubrication management in a circular table shape, in lock chamber
Equipped with the sealing block to match with the second lubrication management.
Further, it is additionally provided with fixed link in the first seal groove and the second seal groove, sealing ring is equipped with and fixed link phase
The fixing groove matched.
Further, the shoe cream room and oil outlet being connected are additionally provided between the first seal groove and the second seal groove.
The deficiencies in the prior art are compared, the utility model has the advantages that when in use brought by technical solution provided by the utility model,
Plunger passes through out of lubrication management and is in contact with the sealing ring in the first seal groove and the second seal groove, because self-lubricating layer is deposited
, therefore can be to avoid because worker's carelessness forgets to add the problem of plunger and plunger bushing are worn caused by lubricating oil hair on time
It is raw, while the first seal groove and the second seal groove are equipped with sealing ring, but also the sealing effect between plunger and plunger bushing is more
Good, the material of sealing ring is rubber, and the internal diameter of sealing ring is slightly less than the diameter of plunger, therefore is bonded between sealing ring and plunger
It is even closer so that sealing effect is more preferable, while when plunger wear, also can guarantee good sealing effect, so that cylinder
The soaking effect of room is more preferable, energy saving.
Detailed description of the invention
Fig. 1 is the plunger bushing cross-sectional view of the utility model.
Fig. 2 is the sealing ring top view of the utility model.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
- Fig. 2 is described further the utility model referring to Fig.1.
A kind of plunger bushing, including body 1 include the first seal groove 11 and the second seal groove 12, the first seal groove on body 1
11 and second seal groove 12 be equipped with sealing ring 4, also set lock chamber on body 1, lubrication management be equipped in lock chamber, is covered on lubrication management
It is stamped self-lubricating layer；Self-lubricating layer is polytetrafluoroethylene (PTFE), when in use, plunger pass through out of lubrication management and with the first seal groove 11
It is in contact with the sealing ring 4 in the second seal groove 12, it, can be to avoid because worker's carelessness be forgotten because of the presence of self-lubricating layer
Remember the problem of plunger and plunger bushing are worn caused by adding lubricating oil on time, while the first seal groove 11 and the second sealing
Slot 12 is equipped with sealing ring 4, but also the sealing effect between plunger and plunger bushing is more preferable, the material of sealing ring 4 is rubber, and
The internal diameter of sealing ring 4 is slightly less than the diameter of plunger, thus be bonded between sealing ring 4 and plunger it is even closer so that sealing effect
Fruit is more preferable, while when plunger wear, also can guarantee good sealing effect, so that the soaking effect of cylinder chamber is more preferable, saves
The energy.
Further, lubrication management includes the first cylindrical lubrication management 31 and the second lubrication management 32 in a circular table shape, is fixed
The intracavitary sealing block 14 being equipped with and the second lubrication management 32 matches；Therefore during installation, the second lubrication management 32 in a circular table shape makes
It must install and be more easier, improve work efficiency.Simultaneously sealing block 14 presence but also lock chamber to the sealing of lubrication management and
Fixed effect is more preferable, while the material of sealing block 14 is rubber, so that can also play the role of buffering.
Further, it is additionally provided with fixed link 13 in the first seal groove 11 and the second seal groove 12, sealing ring 4 is equipped with and fixes
The fixing groove 41 that bar 13 matches, when plunger moves back and forth in plunger bushing, sealing ring 4 can be good at being fixed on first
In seal groove and 11 second seal grooves 12 so that sealing ring 4 will not because of plunger reciprocating motion and in 11 He of the first seal groove
Displacement is generated in second seal groove 12, avoid the displacement of sealing ring 4 and caused by the abrasion of sealing ring 4 and the decline of sealing effect
The problem of occur.
Further, the shoe cream room 21 and oil outlet being connected are additionally provided between the first seal groove 11 and the second seal groove 12
22, shoe cream room 21 is interior filled with solid lubrication oil, therefore plunger and plunger bushing frictional heat generation cause lubricating oil heated from oil outlet
22 flow on plunger, so that lubricant effect is more preferable, reduces the abrasion of plunger and plunger bushing, extend the service life of plunger.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
