Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Hydraulic driving system under a kind of liquid, comprise hydraulic cylinder 1, hydraulic pressure system, compressed air system, pumped vacuum systems, be connected with hydraulic pressure system, compressed air system and pumped vacuum systems on the hydraulic cylinder 1, described hydraulic pressure system is the working medium that hydraulic drives is provided in the system, and the working pressure that keep to need, mainly connect to form by pipeline by small pump 8, low pressure water pot 7, high pressure water pot 3, selector valve 2; Compressed air system is to be communicated with by gas transmission line by air filter 6, air compressor 5, compressed air cylinder 4 to form; Utilize air compressor 5 to filter the pressurized with compressed air that produces and arrive the pressure that needs through air filter 6; High pressure water pot 3 is communicated with under the control of modulating valve by gas transmission line with compressed air cylinder 4.Pumped vacuum systems keeps negative pressure state in the hydraulic cylinder 1, prevent that working medium from escaping to external environment condition, and the liquid that the prevents external environment condition work system of bleeding, pumped vacuum systems is mainly connected to form by pump drainage tracheae line, hydrophobic pipeline by vacuum unit 11, low pressure backwater jar 9, waterback pump 10.Corresponding modulating valve control is all arranged on the connecting pipeline of equipment.
Wherein hydraulic cylinder 1 is an action component, to outside outputting power.
The working principle of this system is as follows:
This system can be applied to the operation in the reactor pond, drives hydraulic cylinder 1 by water, drives power unit, realizes the operation to power unit.
Before the system works, by outside moisturizing working medium water is added to low pressure water pot 7, low pressure water pot 7 is provided with level meter, to guarantee to fill in the jar water of q.s.By small pump 8 water in the low pressure water pot 7 is squeezed into high pressure water pot 3, small pump 8 has enough lifts, to realize that water is squeezed into high pressure water pot 3.High pressure water pot 3 tops are gas, and the bottom is a water, and high pressure water pot 3 is equipped with level meter, and guaranteed water level is not less than job requirement, when triggering the low water level signal, start small pump 8, to high pressure water pot 3 supplementing water.The pressure of high pressure water pot 3 is kept by pressurized air, and pressurized air through compressed air cylinder 4 voltage stabilizings, is squeezed in the high pressure water pot 3 after being pressurizeed through air compressor 5 by the air after filtering through air filter 6 again, is used to keep the pressure of working medium.Adopting the effect of pressurized air voltage stabilizing is in the course of the work, reveals the volume that causes because of working medium and reduces the pressure that can obviously not have influence on liquid.
During system works, selector valve 2 is connected, and working medium water is squeezed into hydraulic cylinder 1 by the water adapter under compressed-air actuated pressure, and the piston in the promotion hydraulic cylinder 1 is to left movement.In the process of piston motion, because piston and shell keep suitable space, the working medium water in the chamber can be infiltrated the piston opposite side by the space, and the water of piston opposite side turns back to low pressure water pot 7 by pipeline, selector valve 2, as standby working medium.When the piston in the hydraulic cylinder 1 needed reversing motion, selector valve 2 switched pipeline and flows to, and make high pressure water enter former outflow pipeline, and another pipeline is realized refluxing, and moves thereby promote piston reverses direction.In whole process, working medium water is in confined state always, can not produce the vaporization of water.
In the process of hydraulic cylinder 1 work, in order to prevent that better working medium is leaked in the working environment, also prevent the liquid contamination working medium in the working environment, in hydraulic cylinder 1 by seal ring with its inside be divided into the pressurized air chamber, the chamber of bleeding, water chamber, in order to isolate the recovery operation medium.Pumped vacuum systems is taken over the water and air that will leak in the chamber of bleeding by bleeding and is outputed in the low pressure backwater jar 9, simultaneously owing in the pressurized air chamber, blast the pressurized air of certain pressure by compressed air system, make the pressure of air pressure, prevented that like this liquid in the external environment condition from entering hydraulic cylinder 1 a little more than liquid in the external environment condition.The pressurized air chamber is leaked to the air in the chamber of bleeding, together enter low pressure backwater jar 9 with water, air in the low pressure backwater jar 9 is discharged through vacuum unit 11, and the water in the low pressure backwater jar 9 enters low pressure water pot 7 through waterback pump 10, can be recycling as standby working medium.
In entire work process, neither have working medium and be leaked in the surrounding medium and go, do not have environmental liquids yet and bleed in the working medium, guarantee pollution-free generation in the working procedure.
