Product Description
Packing Is Also Called Sealing Packing, And It Is Usually Woven
From Softer Threads. It Is Sealed By A Strip With A Square
Cross-Sectional Area In The Sealing Cavity.
Packing Seals Were Originally Plugged With Fibers Such As Cotton
And Hemp In The Leakage Channel To Prevent Liquid Leakage, And Were
Mainly Used As Shaft Seals For Water Lifting Machinery. Due To The
Wide Source Of Filler, Easy Processing, Low Price, Reliable Sealing
And Simple Operation, It Is Still In Use Today. Now Packing Is
Widely Used In Rotary Shaft Seals Of Centrifugal Pumps,
Compressors, Vacuum Pumps, Mixers And Ship Propellers, Piston
Pumps, Reciprocating Compressors, Reciprocating Shaft Seals Of
Refrigerators, And Rotary Seals Of Various Valve Stems, Etc..
PTFE graphite fiber braided packing is made of
polytetrafluoroethylene wire containing graphite particles. It has
a strong tear strength and high thermal conductivity, low friction
coefficient and it makes it stable and long life.

ADVANTAGE
With The Continuous Emergence Of New Materials, There Are Also
Great Changes In The Type Of Filler Structure, Which Will
Undoubtedly Promote The Application Of Filler Seals More Widely.
The Materials Used As Fillers Should Have The Following
Characteristics:
There Is A Certain Elastoplasticity. When The Packing Is Axially
Compressed, It Can Produce A Large Radial Compression Force To
Obtain A Seal; When The Machine And The Shaft Have Vibration Or The
Shaft Has Runout And Eccentricity, It Can Have A Certain
Compensation Capacity (Followability);
Chemical Stability. It Is Neither Corroded, Swelled By The Medium
Nor Polluted By The Medium;
Impermeability. The Medium Has Some Penetration Into Most Fibers,
So The Filler Structure Is Required To Be Dense. Therefore, When
Making The Filler, It Is Often Necessary To Impregnate And Fill
With Various Lubricants And Fillers;
Good Self-Lubrication, Low Friction Coefficient And Wear
Resistance;
Temperature Resistance. When The Friction Heats Up, It Can
Withstand A Certain Temperature;
Easy To Disassemble;
The Manufacturing Is Simple And The Price Is Low.
