Description
Technical field
The utility model belongs to electric power iron and steel Flue Gas Forced Draft Fan technical field, is specially adapted to a kind of thrust cylinder device on large-scale axial flow fan with adjustable moving blades.
Background technique
Along with the fast development of electric power steel industry, energy-efficient axial flow fan with adjustable moving blades product becomes very important equipment in coal generating and iron and steel steelmaking system, and in running, the vane belt system of axial flow fan with adjustable moving blades needs hydraulic system to provide Driving force to regulate.But present hydraulic system exists a lot of problems, mainly in shortcomings such as to there is thrust little, and internal leakage is serious, and oil-way system is complicated.
Model utility content
The utility model is intended to overcome above-mentioned defect, and object is to provide high, the inside and outside good seal performance of a kind of thrust, the simple high thrust oil hydraulic cylinder of oil-way system on axial flow fan with adjustable moving blades.
For achieving the above object, the technical solution adopted in the utility model its primarily of thrust disc, oil hydraulic cylinder side cover, hydraulic cylinder, thrust piston, piston shaft, high pressure petrol station composition; It is characterized in that thrust piston is set on piston shaft, block fixing by axle sleeve, jump ring compression; Thrust piston installs 2 seal rings II on cylindrical, then is set in hydraulic cylinder; Oil hydraulic cylinder side cover is installed on hydraulic cylinder and is locked by high-strength bolt, is provided with O RunddichtringO between oil hydraulic cylinder side cover and hydraulic cylinder; Axle sleeve and sealing place of oil hydraulic cylinder side cover are provided with seal ring I, sliding shaft sleeve I; Hydraulic cylinder and piston shaft sealing place are provided with sliding shaft sleeve II, seal ring III, snap ring; Thrust disc and oil hydraulic cylinder side cover are bolted, and are compressed by seal ring I simultaneously; Piston shaft is provided with oil pipe attachment hole I, oil pipe attachment hole II, the oil pipe of high pressure petrol station respectively with oil pipe attachment hole I, oil pipe attachment hole II.
Owing to adopting technique scheme, between the piston of the utility model in oil hydraulic cylinder and cylinder body, special sealing configuration is set, decrease internal leakage, improve thrust and the stability of blower fan, piston shaft designs oil circuit, and relative to comparing at oil hydraulic cylinder outer installment oil channel structures in the past, structure was simpler, outside shared volume reduces, and decreases the installing space of oil hydraulic cylinder in axial flow fan with adjustable moving blades.
