Description
Technical field
The utility model belongs to seal arrangement technical field, specifically, relates to folder cloth concrete piston for high-pressure slurry pump seal for a kind of engineering machinery.
Background technique
High pressure slurry pump folder cloth concrete piston is the vitals of construction engineering and drilling machinery slurry transportation pump, its reciprocating sealing in mud, crude oil medium; Current conventional assembly type mud piston, the pure polyurethane material manufacture of its many employing, though polyurethane products have fabulous elasticity and wear resistance, but because its resistance to high temperature is poor, easily hydrolyzed, friction factor be large, cause pump truck continuing to cause when long distance is carried the piston deliquescing seal failure of being clamminess, working life is short, while working, piston and cylinder body produce great friction noise and also can produce the problem of harm to surrounding enviroment and personnel simultaneously, for this reason, need a kind of high pressure slurry pump folder cloth concrete piston that can address the above problem, with this, meet the needs of actual conditions.
Model utility content
The utility model provides a kind of high pressure slurry pump folder cloth concrete piston, and it can solve the problems referred to above that exist in currently available technology, strengthens the whole resistance to pressure of product and wear resistance.
The technological scheme that the utility model adopts is:
High pressure slurry pump folder cloth concrete piston, it comprises rubber body, cylindrical folder cloth part and end circle root folder cloth part; Described rubber body, cylindrical folder cloth part and end circle root folder cloth are partly by the fastening adhering junction of sulfuration.
Described cylindrical folder cloth is partly provided with at least one transverse annular oil storage tank.
The sectional shape of described oil storage tank is triangle, quadrilateral, arc or other shapes.
High pressure slurry pump folder cloth concrete piston of the present utility model, it is by adopting rubber and the whole composite structure of folder cloth enhancement layer and being coated with plastic clip cloth MULTILAYER COMPOSITE as root reinforced layer, strengthen resistance to pressure, wear resistance, the rebound elasticity of product integral body, reduce the frictional force of concrete piston and cylinder sleeve, piston root size is suitably strengthened simultaneously, improve root sealing, increase the service life; There is high hardness, high strength, high wear resistance, good rebound elasticity and oil resistance, and have the good features such as adhesive property with fabric; With respect to nitrile butadiene rubber tensile strength, tear strength, hardness, wear resistance, stickability and anti-ozone aging etc., be all greatly improved; Improve ageing-resistant performance, improve wear resistance; There is time of scorch length and the good feature of sulfuration flatness.
