Abstract
The utility model provides a hydraulic working cylinder. A cylinder end is connected to the port of a cylinder tube; one end of a piston rod is connected with a piston in the cylinder tube through the cylinder end; an inner industrial enamel layer and an outer industrial enamel layer are arranged on the inner cylindrical surface of the cylinder tube and the outer cylindrical surface of the piston rod respectively; the cylinder end is connected with a gland bush; a first sealing piece connected with the cylinder end and the gland bush is in slide fit with the outer industrial enamel layer; and a second sealing piece connected with the piston is in slide fit with the inner industrial enamel layer.
Description
Technical field:
The utility model relates to a kind of hydraulic work cylinder, especially a kind of hydraulic work cylinder that uses under the mine of dark humidity.
Background technique:
Conventional hydraulic work cylinder, when being used to be corrosive the pressure transmission fluid, in order to solve corrosion and wear problems, the relevant expert has invented the scheme that is coated with non-ferrous metal coating on cylinder barrel wall inner cylindrical surface and piston rod external cylindrical surface, these coating have been brought into play good effect under conventional environment, but in strong wearing and tearing of acid and alkali corrosion hydraulic medium and dust and humid atmosphere are arranged, particularly under dark moist mine, because the complex effects of various cruel conditions, cause non-ferrous metal coating generation rust staining even cavitation pitting, these patches are pulled Sealing, leakage causes these parts to be scrapped very soon.And the serious environmental pollution of generation in the process that is coated with non-ferrous metal coating.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can rust staining and corrosion can not occur in the rugged environment that strong wearing and tearing of acid and alkali corrosion hydraulic medium and dust and humid atmosphere are arranged, thereby obviously increases the service life and do not produce the hydraulic work cylinder of environmental pollution in manufacture process.
The purpose of this utility model can realize by following technical measures:
The cylinder barrel port of this hydraulic work cylinder is connected with the cylinder end head, and an end of piston rod is connected with the piston that is positioned at cylinder barrel by the cylinder end head, in the external cylindrical surface of the inner cylindrical surface of cylinder barrel, piston rod has respectively the industrial enamel layer and outside the industrial enamel layer.
The purpose of this utility model also can realize by following technical measures:
The cylinder end head connects gland, and first Sealing that connects cylinder end head and gland is slidingly matched with outer industrial enamel layer, and second Sealing that is connected with piston and interior industrial enamel layer are slidingly matched.
The utility model applies the industrial enamel layer that one deck alkali corrosion resistance is functional, abrasion strength resistance is high respectively at the inner cylindrical surface of steel cylinder cylinder barrel, the external cylindrical surface of piston rod, and will carry out grinding with grinding machine with the position that Sealing is slidingly matched according to needed precision and degree of finish.
Firmly being connected with one deck on the utility model inner wall of cylinder cylndrical surface and the piston rod external cylindrical surface can use under the condition that seriously strong wearing and tearing of moist and dust and corrosive liquids co-exist in for a long time, and the industrial enamel layer that rust staining, corrosion and heavy wear phenomenon can not occur, though the utility model is under such severe environmental conditions, still can obviously prolong 4-5 working life doubly, in addition, in the utility model manufacture process, do not produce any environmental pollution.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment:
This hydraulic work cylinder, cylinder barrel 1 port is connected with cylinder end head 9, cylinder end head 9 connects gland 8, first Sealing 5 that connects cylinder end head 9 and gland 8 is slidingly matched with outer industrial enamel layer 7, one end of piston rod 6 is connected with the piston 2 that is positioned at cylinder barrel 1 by cylinder end head 9, second Sealing 3 that is connected with piston 2 is slidingly matched with interior industrial enamel layer 4, inner cylindrical surface at cylinder barrel 1 firmly connects one deck industrial enamel layer 4, external cylindrical surface at piston rod 6 firmly connects one deck industrial enamel layer 7, and described industrial enamel layer 4,7 is all processed with grinding machine.
