Abstract
The utility model discloses a novel oil tank device of a hydraulic machine. The novel oil tank device comprises a main oil tank, a main pressure oil cylinder, an upper oil tank and a prefill valve. An air inlet one-way valve and a safety valve are arranged at an upper end of the upper oil tank, the prefill valve is arranged between the upper oil tank and the main pressure oil cylinder, and the main oil tank is communicated with the upper oil tank through a pipeline. Compressed air is pressed in through the air inlet one-way valve when the oil cylinder extends out at a maximum level. Actual pressure of the compressed air in the oil cylinder is measured when the oil cylinder extends out at a minimum level, and start pressure of the safety valve is set to be slightly higher than the actual pressure. When a piston rod extends out under the act of gravity or other fluid power, the prefill valve opens, oil in the oil tank is pressed into a rodless cavity of the oil cylinder by air pressure besides gravity and suction, when the piston rod extends enough to start working, the prefill valve closed, and the rodless cavity of the oil cylinder is basically full of oil, vacuum space is reduced and even becomes zero, when pressure is added and the piston rod starts working, pressure oil directly starts adding pressure and works. The novel oil tank device of the hydraulic machine is simple in structure, power energy is saved, and production efficiency is improved.
Description
Technical field:
The utility model relates to a kind of mailbox, particularly relates to a kind of novel hydraulic machine tank mounting of gas type.
Background technique:
Oil tank of hydraulic machine, is the device that hydraulic press stores liquid, and existing oil tank of hydraulic machine communicates with atmosphere substantially.When piston rod leans on gravity or other fluid power effect realization to stretch out fast, liquid-filling valve is opened, and fuel tank inner fluid enters oil cylinder rodless cavity by gravity and suction, stretches out and puts in place while starting working, liquid-filling valve cuts out, now oil cylinder rodless cavity is not generally full of fluid ，Shang You vacuum space, while starting pressurized operation, first pressure oil need filled vacuum part, side can start pressurized operation afterwards, has above-mentionedly not only wasted time and the energy, and has reduced the manufacturing efficiency of equipment.
Model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of and can economize on resources and the energy, improve the novel hydraulic machine tank mounting of production efficiency of equipment.
The utility model is that the technological scheme that technical solution problem is taked is:
A kind of novel hydraulic machine tank mounting, comprise main fuel tank and main compressing cylinder, also comprise top tank and liquid-filling valve, described top tank upper end is provided with breather check valve and safety valve, between described top tank and described main compressing cylinder, be provided with described liquid-filling valve, described main fuel tank is connected by pipeline and top tank.
Described novel hydraulic machine tank mounting also comprises hydraulic power unit.
Main fuel tank of the present utility model and top tank communicate, and oil cylinder stretches out when the longest compresses into pressurized air by breather check valve; Oil cylinder stretches out measures fuel tank compressed air actual pressure the most in short-term, and opening pressure of safety valve is set as a little more than actual pressure.When piston rod leans on gravity or other fluid power effect realization to stretch out fast, liquid-filling valve is opened, fuel tank inner fluid is except leaning on gravity and suction, also have compressed air pressure to be pressed into oil cylinder rodless cavity, stretch out and put in place while starting working, liquid-filling valve cuts out, now in oil cylinder rodless cavity, be substantially full of fluid, reduce even not had vacuum space, while starting pressurized operation, pressure oil directly starts pressurized operation.This structure has not only been saved time and the energy, and has improved the manufacturing efficiency of equipment.
The utlity model has advantage simple in structure, to save power source, raising production efficiency of equipment.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further explained and explanation:
Referring to Fig. 1, a kind of novel hydraulic machine tank mounting, comprise main fuel tank 6 and main compressing cylinder 1, also comprise top tank 4, liquid-filling valve 5 and hydraulic power unit, top tank 4 upper ends are provided with breather check valve 2 and safety valve 3, between top tank 4 and main compressing cylinder 1, be provided with liquid-filling valve 5, main fuel tank 6 is connected by pipeline and top tank 4.
In actual application: compress into pressurized air when oil cylinder stretches out when the longest by breather check valve 2; Oil cylinder stretches out measures fuel tank compressed air actual pressure the most in short-term, and safety valve 3 cracking pressures are set as a little more than actual pressure.When piston rod leans on gravity or other fluid power effect realization to stretch out fast, liquid-filling valve is opened, and fuel tank inner fluid, except by gravity and suction, also has air pressure to be pressed into oil cylinder rodless cavity, stretch out and put in place while starting working, liquid-filling valve cuts out, and now in oil cylinder rodless cavity, is substantially full of fluid, reduces even not had vacuum space, while starting pressurized operation, pressure oil directly starts pressurized operation, has above-mentionedly not only saved time, the energy, and has improved production efficiency of equipment.
The utlity model has advantage simple in structure, to save power source, raising production efficiency of equipment.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, within all still belonging to the protection domain of technical solutions of the utility model.
