Description

The inner-cooled hydraulic booster machine of natural gas supply sub-station
Technical field
The present invention relates to natural gas equipment, particularly a kind of inner-cooled hydraulic booster machine of natural gas supply sub-station.
Background technique
, along with continuous progress and the development of technology, there is the type of multiple different operating principle and structure in the compressor of natural gas equipment.Gas compression is an exothermic process, can produce a large amount of heats, and gas temperature is raised, and the larger temperature rise of compression ratio is higher.This temperature rise not only can impact the life-span of some Sealings, can reduce air inflow and air displacement be reduced simultaneously.
Generally the overall compression ratio of natural gas compressor is up to more than 8, so structure many employings implements spatial scalable compression of compressor.All have to pass through cooling system after every one stage of compression, the temperature of pressurized gas is dropped to 40 ~ 45 DEG C, then enter next stage compression.Therefore, the natural gas compressor of different operating principle and different structure, their cooling system is different, be broadly divided into three types: mechanical piston formula natural gas compressor, hydraulic piston type natural gas compressor, hydraulic bottle pushing-type natural gas compressing device, their technology that cools is as follows:
1. crank-connecting rod piston compressor
Crank-connecting rod piston compressor is a kind of traditional product of Technical comparing maturation, uses comparatively wide, but its complicated structure, and manufacture requirements is higher, its working principle be by crank-driven connecting rod piston in cylinder reciprocating come pressurized gas.In order to Appropriate application kinetic energy with take away heat in time, it often adopts implements spatial scalable compression, cascade EDFA structure.Concrete structure is, at the casing wall of every grade of compression cylinder, the jacket space around circumference is set, take away the heat of gas compression generation with circulating water, its cooling procedure is that the heat that gas compression produces conducts in the circulating water in the water jacket of outside via compression casing wall, is walked the heat of gas by water-band.But, because the strong fast inertia reciprocating friction motion of piston crank mechanism also produces amount of heat, the high heat that two kinds of heats accumulate, cause the heat dissipation rate of water jacket mode not catch up with the speed of gas compression and the high heat of piston rod reciprocating friction motion generation, the cooling-down effect of water jacket is still undesirable.In order to suppress the zooming temperature in machine operation process, also need to configure powerful Air cooler air-cooled to implement, thus cause the mechanical efficiency of whole compressor not high, power consumption is larger.
2. hydraulic piston type natural gas compressor
Hydraulic piston type natural gas compressor is a kind of equipment utilizing the hydraulic system piston promoted in compression cylinder to carry out gas compression.It uses high pressure oil Direct driver piston compression gas, the amount of heat of gas discharging in compression process, wherein a part is conducted by compression cylinder casing wall and is spread out in air, part heat conducts to hydraulic oil by metallic piston, take away when flowing back to fuel tank by hydraulic oil, but main heat still need be taken out of high-temperature gas out in cylinder, therefore need arrange classification water cooler on the pipeline of gas flow warp and cool, thus causing the complex structure of air delivering pipeline, repair and maintenance is extremely inconvenient.
3. hydraulic bottle pushing-type natural gas compressing device
Natural gas supply sub-station is also had now to adopt hydraulic bottle pushing-type natural gas compressing device, hydraulic bottle pushing-type natural gas compressing device arranges high-voltage tube by natural gas transportation tank car to be connected with hydraulic bottle pushing-type natural gas compressing device, utilize the high pressure oil pump of hydraulic bottle pushing-type natural gas compressing device to conveying liquid force feed in the air cylinder of natural gas transportation tank car as working medium, directly high pressure oil low speed is injected lentamente in the air cylinder of natural gas transportation tank car by high pressure oil pump, with the rock gas in the high pressure oil extruding air cylinder injected, natural gas compressing is made to reach high pressure.The heat that gas produces in compression process, a part relies on the conduction of gas storage cylinder bottle to be dispersed in air, and another part then conducts to the hydraulic oil of extruding rock gas, after rock gas is squeezed out air cylinder, is taken away by heat by the hydraulic oil of backflow fuel tank.But this structure because of rock gas be in compressive state time, hydraulic oil is in injection state, the heat that natural pressure compression process produces, except conduction to a part of heat of gas storage cylinder bottle by bottle conduction distribute except, conduct to a part of heat of hydraulic oil, before hydraulic oil does not reflux fuel tank, still be gathered in gas storage cylinder, cause heat radiation slowly, the time is longer, and the danger of working procedure increases.And, when carrying out natural gas compressing owing to adopting the air cylinder injection liquid force feed of hydraulic bottle pushing-type natural gas compressing device to natural gas transportation tank car, air cylinder on transport tank car must be in setting or lateral attitude, such guarantee when oiling is pressurizeed rock gas upper, hydraulic oil under state, rock gas is enable to be squeezed out air cylinder, therefore, partly pulling bearing chassis and must reequip natural gas transportation tank car, the lifting bracket of lying on the back of a set of hydraulic lift will be set in bearing chassis increase, air cylinder just can be made to erect or tilt, like this by causing natural gas transportation tank car fabricating cost to strengthen.
And; the hydraulic system of existing various natural pressure compression apparatus does not all have the automatic supplementary functions of hydraulic oil; when hydraulic oil produces low on fuel phenomenon in the course of the work because of leakage; can not realize online automatically supplementary in time; need shut down carry out hydraulic oil supplement; cause gas station operating interruptions, impact normally works.
