Embodiment Construction

[0011] A step-by-step pressurized fuel tank, including: fuel tank body 1, fuel tank cover 2, booster piston 3, O-ring seal 4, piston seal 5 and spring 6, and also includes: push rod housing 7, a first-stage push rod 8. Secondary push rod 9, guide ring A10, piston rod seal A11, guide ring B12, guide ring C13, piston rod seal B14 and guide ring D15. The push rod housing 7 has a stepped through hole in the axial direction. One end of the push rod housing 7 is a flange, and the outer end surface of the flange has a sealing groove. There are piston rod sealing grooves and piston rod guide grooves in turn. The first-stage push rod 8 has a stepped through hole in the axial direction, and there is a groove on the outer surface of one end of the first-stage push rod 8, and the inner wall of the through hole at the other end has a piston rod sealing groove and a piston rod guide in turn from the end surface. groove. Grooves are arranged on the outer surface of the secondary push rod 9...

Abstract

The invention discloses a progressive pressurizing oil tank, which comprises an oil tank body (1), an oil tank cover (2), a pressurizing piston (3), an O-shaped sealing ring (4), a piston sealing element (5), a spring (6), a push rod casing (7), a primary push rod (8), a secondary push rod (9), a guide ring A (10), a piston ring sealing element A (11), a guide ring B (11), a guide ring C (13), a piston rod sealing element B (14) and a guide ring D (15). In the work process, under the effect of high-pressure oil at an outlet of a hydraulic pump, the primary push rod (8) and the secondary push rod (9) push the pressurizing piston (3) to pressurize the oil tank, the primary push rod (8) extends to the maximum stroke, and the secondary push rod (9) continuously pushes the pressurizing piston (3) for pressurizing the oil tank. The progressive pressurizing oil tank has the advantages that a progressive extending-out pressurizing mode is adopted, the effective stroke of the pressurizing piston (3) and the oil storage quantity of the oil tank can be increased under the condition of the same installing space environment, and the use requirements of small space and great volume are met.

Description

technical field [0001] The invention relates to a self-pressurized oil tank, in particular to a step-by-step pressurized oil tank. Background technique [0002] The self-pressurized fuel tank of the hydraulic system is to drain the high-pressure oil of the system to the high-pressure chamber of the fuel tank, and use the area difference between the high-pressure chamber and the low-pressure chamber of the fuel tank to realize the pressurization of the fuel tank. It has good anti-pollution ability and can effectively improve the self-priming of the hydraulic pump in a low-pressure environment. Good performance and environmental adaptability. After vacuuming and oil filling, placing it in any direction can ensure that the oil in the fuel tank is always in a compressed state and ensure the normal oil suction of the hydraulic pump. The traditional self-pressurized fuel tank is mainly composed of a fuel tank body, a fuel tank cover, a booster piston, a spring and a hydraulic sea...
