Description
Technical field
The invention belongs to field of sealing technology, and in particular to a kind of dust seal.
Background technology
As domestic economy continues to develop, national life level improves constantly, and the industry of numerous domestic industrial and mining enterprises is automatic
Change degree further improves, and sealed product performer key player in industrial automation, the quality of sealed product quality,
In industrial automation key effect is played in terms of dynaflow.Particularly concerning country's weight large scale equipment of national economy
In, the stabilization of sealed product performance, the reliable of quality and the tolerance to various fluid media (medium)s, all it is very important.Together
When, it is not only expensive using the seal of developed countries import at home in great type key equipment, and arrival
Cycle is grown.
The content of the invention
According to above the deficiencies in the prior art, the technical problems to be solved by the invention are to propose a kind of dust seal, energy
Enough ensure good dust seal effect.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of dust seal, the dust seal on kinematic axis, dust seal are arranged on one that kinematic axis stretches out casing
On end, the dust seal include be arranged on kinematic axis end cap, be arranged on kinematic axis sealing ring, be arranged on kinematic axis
Sponge lasso of circumferential, fuel tank, connection fuel tank and end cap between oil inlet pipe, connection fuel tank and end cap between flowline, be arranged on
Felt collar on end cap and the oil pump being arranged on oil inlet pipe；The oil of sealing is provided with fuel tank.
The sealing ring is enclosed on kinematic axis and contacted with casing, and end cap is enclosed on kinematic axis, and end cap points to casing
One end contacts with sealing ring.The place that the end cap contacts with kinematic axis is provided with groove, and felt collar is provided with groove.The sponges cover
Circle is arranged on kinematic axis the position between sealing ring and end cap.The end cap is provided with oil inlet and oil-out, is set on fuel tank
Have an inlet and outlet, the both ends of the flowline connect oil-out and import respectively, the both ends of the oil inlet pipe connect respectively into
Hydraulic fluid port and outlet.Cover internal is stretched into one end end that the oil inlet pipe is connected with oil inlet, and oil inlet pipe stretches into cover internal
End is provided with check valve.The flowline is provided with pressure valve, and the pressure of only cover internal oil is more than the pressure of pressure valve
When, pressure valve is just opened.
Present invention has the advantages that:Good dust seal effect can be ensured.Fluid splashing will not be produced.
Brief description of the drawings
The content expressed by this specification accompanying drawing and the mark in figure are briefly described below：
Fig. 1 is the structure chart of the embodiment dust seal of the present invention.
Embodiment
