Description
Technical field
The utility model relates to one can reduce noise, improves the novel hydraulic equipment of service life of equipment, especially relates to a kind of novel linear reciprocating motion type oil hydraulic cylinder.
Background technique
Oil hydraulic cylinder be by hydraulic energy transfer be unload can the hydraulic actuator doing straight reciprocating motion, its structure is simple, reliable operation, when realizing to-and-fro motion with it, speed reducer can be removed from, and there is no drive gap, stable movement, hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion by oil hydraulic cylinder.Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be widely applied in the hydraulic system of various machinery.When hydraulic cylinder is to having larger kinetic energy during stroke end, as do not done process of slowing down, will there is mechanical collision in hydraulic cylinder piston and cylinder cap, produce impact, noise, have destructiveness.Oil hydraulic cylinder internal leakage comprises hydraulic cylinder sealing, piston rod and seal cap sealing and piston seal and all to wear and tear the leakage caused such as excessive.Therefore be used widely in the hydraulic system of various machinery.Unreasonable due to Sealing, makes the poor sealing performance generation phenomenon of leakage of oil hydraulic cylinder.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of novel linear reciprocating motion type oil hydraulic cylinder, there is cylinder barrel 1, cylinder cap 2 and piston 3, outer surface by cylinder barrel 1 is coated with anticorrosive coat 4, cylinder barrel 1 is provided with cylinder cap 2, the external diameter of piston 3 is provided with the modes such as seal ring 5, make this product hermeticity energy good, structure is simple, easy to use, has good sealability, the phenomenon of leakage can not be caused, reliable operation, cost-saving, extend product working life.
1, the utility model solves the technological scheme that its technical problem adopts and is: a kind of novel linear reciprocating motion type oil hydraulic cylinder, there is cylinder barrel 1, cylinder cap 2 and piston 3, it is characterized in that: the outer surface of described cylinder barrel 1 is coated with anticorrosive coat 4, cylinder barrel 1 is provided with cylinder cap 2, the external diameter of piston 3 is provided with seal ring 5.
Described cylinder barrel 1 there is oil leak hole 6.
Described piston 3 is provided with relief valve 7.
Described cylinder cap 2 is provided with safety valve 8.
Spring 9 is had between described piston 3 and cylinder barrel 1.
The beneficial effects of the utility model are: 1, due to novel linear reciprocating motion type oil hydraulic cylinder, have cylinder barrel 1, cylinder cap 2 and piston 3, the outer surface by cylinder barrel 1 are coated with anticorrosive coat 4, cylinder barrel 1 is provided with cylinder cap 2, the external diameter of piston 3 is provided with the modes such as seal ring 5, make this product hermeticity energy good, structure is simple, easy to use, there is good sealability, can not the phenomenon of leakage be caused, reliable operation, cost-saving, extend product working life;
2, due to described cylinder barrel 1 having oil leak hole 6, when hydraulic cylinder is to having larger kinetic energy during stroke end, as do not done process of slowing down, will there is mechanical collision in hydraulic cylinder piston and cylinder cap, produce impact, noise, have destructiveness.So arrange an oil leak hole on cylinder barrel, can effectively prevent this situation from occurring;
3, because described piston 3 is provided with relief valve 7, piston 3 plays compacting oil and plays power-converting effect, and oil pressure is excessive sometimes, needs overflow pressure regulating valve size, and avoid piston to be damaged by pressure distortion, relief valve plays the effect of safety backpressure;
4, because described cylinder cap 2 is provided with safety valve 8, cylinder cap is provided with safety valve, when oil cylinder internal pressure excessive can not pressure release time, need the overflow relief valve on cylinder cap to assist pressure release, effectively avoid oil cylinder to be damaged by oil pressure;
5, owing to having spring 9 between described piston 3 and cylinder barrel 1, effectively add maneuverability, elastic compensating effect is better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structure schematic diagram of a kind of novel linear reciprocating motion type oil hydraulic cylinder described in the utility model.
In figure: 1, cylinder barrel; 2, cylinder cap; 3, piston; 4, anticorrosive coat; 5, seal ring; 6, oil leak hole; 7, relief valve; 8, safety valve; 9, spring.
