Abstract
The utility model relates to drilling mud pump piston assembly, particularly mud piston assembly; This mud piston assembly, comprises piston main body and combination sealing arrangement, and wherein: described combination sealing arrangement is located at piston main body afterbody, described combination sealing arrangement comprises: teflon circle, O type circle, piston rubber; The utility model drilling mud pump piston adds a kind of wear-resisting combination sealing arrangement by afterbody, prevents silt particle from entering the premature breakdown causing piston in the middle of the stripper rubber of piston and cylinder sleeve, improves piston working life.
Description
Technical field
The utility model relates to drilling mud pump piston assembly, particularly mud piston assembly.
Background technique
In current drillng operation, drilling mud pump piston mainly relies on the rubber part of piston to realize sealing, in use, silt particle enters in the middle of piston and cylinder sleeve, piston rubber is caused to cross quick-wearing, piston is reduced working life, also to change piston after wearing and tearing, not only affect job schedule, also can add the labor intensity of staff.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of wear-resisting drilling mud pump piston, and this piston adds a kind of wear-resisting combination sealing arrangement by afterbody, in the middle of the stripper rubber preventing silt particle from entering piston and cylinder sleeve, causes the premature breakdown of piston.
To achieve these goals, the utility model is achieved in that a kind of mud piston assembly, comprise piston main body and combination sealing arrangement, described combination sealing arrangement is located at piston main body afterbody, and wherein combination sealing arrangement comprises: teflon circle, O type circle, piston rubber.
Establish T-shaped groove outside described piston main body, in described T-shaped groove, establish O type circle and the combination of teflon circle.
Described teflon circle and O type circle form two way sealed.
The combination that described O type circle is located at inside T-shaped groove, teflon circle is located at outside O type circle is located at outside piston main body end.
Described piston rubber is located at outside piston main body butt ends.
Described piston main body, according to the different size of pump, can be designed to a series of Dimensions: Φ 80, Φ 90, Φ 100---Φ 180.
The utility model mud piston assembly mainly adds a kind of wear-resisting combination seal in piston tail, is made up of piston main body, teflon circle, O type circle, piston rubber.Piston rubber forms overall structure together with being cast in piston main body, and O type circle is combined with inside and outside teflon circle, realizes wear-resisting Bidirectional slide sealing; Prevent sand from entering the damage causing piston between plunger rubber and cylinder sleeve, improve piston working life.
Accompanying drawing explanation
Accompanying drawing 1 is the sectional view of mud piston assembly.
In figure: piston main body 1, teflon circle 2, O type circle 3, piston rubber 4.
Embodiment
Below in conjunction with accompanying drawing (as shown in Figure 1), the utility model is described further:
A kind of mud piston assembly, comprise piston main body 1 and combination sealing arrangement, described combination sealing arrangement is located at piston main body 1 afterbody, and wherein combination sealing arrangement comprises: teflon circle 2, O type circle 3, piston rubber 4.The type of O shown in Fig. 1 circle 3 combines formation two way sealed with teflon circle 2, in use, teflon circle 2 plays wear-resisting effect in Bidirectional slide, the stressed effect playing Expansion sealing and teflon circle 2 wear compensation of O type circle 3, by under the acting in conjunction of O type circle 3 and teflon circle 2, preventing silt particle from entering in the middle of piston and cylinder sleeve caused piston rubber 4 early to wear and tear, improve the working life of piston, extend the piston replacement cycle, reduce the labor intensity of staff.
