Abstract
The utility model relates to a kind of steering tool hydraulic module piston seal protective gear.Mainly solve the problem that traditional underground hydraulic pressure module O type circle seals easy seal failure.It is configured to rubber sleeve (2) is the round column structure that there are through hole in two bottom center, be wrapped on piston, rubber sleeve (2) bottom contacts with piston lower surface, and with snap ring, rubber sleeve bottom is fixed, piston pressing plate (3) is arranged on the piston of cover rubber sleeve (2), and is tightened with piston bolt (1).It is good that the utility model has sealing effect, improves piston working life, install simultaneously, the feature of convenient disassembly.
Description
Technical field
The utility model relates to oil field well hydraulic module seal arrangement, specifically a kind of steering tool hydraulic module piston seal protective gear.
Background technique
Drilling equipment all needs in down-hole to seal its components and parts, and O RunddichtringO is a kind of conventional encapsulating method, but in the piston movement process of hydraulic module, O type circle and mud contacts, easy seal failure, affects the working life of hydraulic module piston greatly.
Model utility content
For solving Problems existing in background technique, the utility model proposes a kind of good sealing effect, substantially increasing hydraulic module piston working life, installing simultaneously, a kind of steering tool hydraulic module piston seal protective gear of convenient disassembly.
The technological scheme that the utility model adopts is: rubber sleeve is the round column structure that there are through hole in two bottom center, be wrapped on piston, rubber sleeve bottom contacts with piston lower surface, and with snap ring, rubber sleeve bottom is fixed, piston pressing plate is arranged on the piston of cover rubber sleeve, and is tightened with piston bolt.
The beneficial effects of the utility model are: the technological scheme adopted owing to have employed the utility model instead of the sealing means of original employing O type circle; avoid because causing the problem of seal failure with mud contacts; thus substantially increase the working life of a fluid die piston; the utility model installation simultaneously, convenient disassembly, achieve the seal protection of hydraulic module piston in limited space.
Accompanying drawing explanation
Fig. 1 is the utility model organigram.
In figure, 1-piston bolt, 2-rubber sleeve, 3-piston pressing plate, 4-hydraulic module.
Embodiment
Be described further below in conjunction with accompanying drawing reader model utility.
As shown in Figure 1; a kind of steering tool hydraulic module piston seal protective gear; be arranged on the piston of hydraulic module 4; rubber sleeve 2 is the round column structure that there are through hole in two bottom center; be wrapped on piston, rubber sleeve 2 bottom contacts with piston lower surface, and is fixed rubber sleeve bottom with snap ring; piston pressing plate 3 is arranged on the piston of cover rubber sleeve 2, and is tightened with piston bolt 1.
During assembling, first fill lubricant grease by rubber sleeve 2, be pressed into by upper piston area during assembling, the bottom of rubber sleeve 2 contacts with piston lower surface, then fixes with the bottom of snap ring by rubber sleeve; Piston pressing plate 2 is placed on piston middle, by piston bolt frock, piston bolt is screwed.
