    [DESCRIPTION][Invention Title] PUMP AND GAS BUSTER USING THE SAME [Technical Field] The present invention relates to a pump and a gas buster using the same, and moreparticularly, to a pump Which is capable of adding a gas as a compressible fluid to a pumpedincompressible fluid and then extruding the gas, and a gas buster using the same.
    [Background Art] Generally, a pump for carrying a fluid or slurry is selected according to various factorssuch as a head pressure, a measuring accuracy, a temperature, a particle tolerance, a fluidviscosity, a price, stability and service fee.
    A positive displacement pump includes a reciprocating pump as a lobe pump and arotary pump. The reciprocating pump includes a mechanical/pneumatic piston pump and amechanical/hydraulic diaphragm pump. The reciprocating pump has a structure in Which oneor more heads for transferring a fluid between a low pressure input side and a high pressureoutput side are provided, and a means for physically controlling an intemal volume of apumped fluid is installed at a pump head. A piston installed at a pump housing of thereciprocating pump is driven by a cam or a crank shaft and a connecting rod. The pistonWhich reciprocates along a cylinder of the pump housing sucks the fluid from an inlet port,While increasing the intemal volume of the cylinder, and discharges the fluid to an outlet port,While reducing the intemal volume.
    Most of the reciprocating pumps operate in only one direction. A floWing direction iscontrolled by a check valve, and the check valves iso late an inlet/outlet port pressure from the pump head during sucking and discharging processes. In general, the outlet port pressure is not controlled by the pump, but is controlled by a downstream side resistance of the Workingfluid due to the pump.
    When the reciprocating pump is used in a high compressible fluid such as gas, it iscalled a compressor or a gas buster. A basic core element of the gas buster is a compressionratio. The compression ratio is a ratio of a maximum volume in Which the pump head may beisolated between check valves at a peak of an intake stroke and a minimum volume Which isreduced to an end of a delivery stroke.
    In the pump, to increase a compression pressure of the compressible gas, it isrecommended that the volume is as small as possible and the compression ratio is increased.When the pump is operated and a high temperature gas is remained in the pump, pumpefficiency is loWered, and this is because the remaining fluid expands in the cylinder duringthe intake stroke, before a new fluid is introduced into the pump head. Due to such an action,it is difficult to compress the gas as the compressible fluid With a high pressure using the gasbuster. To compress the gas With the high pressure, a multistage pump is used. However, themultistage pump has a relatively complicated structure.
    [Disclosure][Technical Problem] The present invention is directed to providing a pump Which is capable of adding a gasas a compressible fluid to a pumped incompressible fluid and then extruding the gas, and agas buster using the same.
    Also, the present invention is directed to providing a pump Which is capable ofseparating the gas added to the incompressible fluid, and compressing the gas, and thusincreasing compression efficiency of the gas, and also enhancing lubricity of a piston and acylinder as driving parts of the pump, and a gas buster using the same.

    FIG. 3 extracts and illustrates the cylinder part and the auxiliary cylinder part of thepump, and is a cross-sectional View illustrating a state in Which the incompressible fluidadded to a gas is compressed through a first outlet port to compress the incompressible fluid.
    [Modes of the Invention] A pump and a gas buster using the same according to the present invention add a gasto a fluid, and then compress the gas, and one embodiment thereof is illustrated in FIGS. 1 to3.
    Referring to the drawings, a gas buster 10 according to the present invention includesa pump 20 having a pump housing 23 in Which a cylinder part 22 is provided to add a gas tobe compressed to an incompressible fluid in a compression driving part 21 and then to pumpthem, a storage tank 60 connected between a first exhaust part 30 of the pump 20 and a supplypipe 61, and having an intemal space in Which the gas added to the fluid is separated, and alsoconfigured to compress the separated gas, and a gas supply part 70 having a retum pipe 62 forconnecting the storage tank 60 With a first intake part 40 in communication With the cylinderpart 22 of the pump 20, and configured to supply the gas to be compressed into the cylinderpart 22 for pumping a compressed fluid.
    The compression driving part 21 of the pump 20 for compressing an incompressiblefluid added to the compressible gas includes a piston 21a Which is reciprocably installed in thecylinder part 22 provided at the pump housing 23 to suck the incompressible fluid through thefirst intake part 40 and then to exhaust the incompressible fluid through the first exhaust part30, and a piston driving part 21b Which moves the piston 21a forward and backWard along thecylinder part 22. A plurality of pistons and cylinder parts may be installed at the pumphousing 23. The piston driving part 21b includes a crank shaft Which is driven by an engineor a motor, and a connecting rod Which connects the crank shaft and the piston so as toconvert a rotating force of the crank shaft into a linear reciprocating motion.
    The compression driving part is not limited to the above-described embodiment, andmay include a vane, a gear and an impeller Which are installed in the cylinder part, and a driving part Which rotates the vane, the gear and the impeller.
    A first check valve 3l Which is opened by the compression driving part 21 When thefluid is sucked, and closed When the fluid is compressed is installed at the first intake part 30installed to be in communication With the cylinder part 22, and a second check valve 4l Whichis opened by the compression driving part 2l When the fluid is compressed, and closed Whenthe fluid is sucked is installed at the first exhaust part 40. The check valve does not have to beinstalled at the first intake part 30 and the first exhaust part 40, Which are in communicationWith the cylinder part, according to kinds and characteristics of the compression driving part.
    MeanWhile, the pump housing 23 fiarther includes an auxiliary cylinder part 22a to addthe gas to the incompressible fluid pumped by the cylinder part 22 and the piston 2la. Theauxiliary cylinder part 22a may be integrally formed With the pump housing 23.Altematively, an auxiliary pump housing having the auxiliary cylinder part may bemanufactured and then installed at the pump housing 23 so that the cylinder part 2l is incommunication With the auxiliary cylinder part 2la(22a). Here, it is preferable that theauxiliary cylinder part 22a is in communication With the cylinder part 22, and extends in anupper direction of the cylinder part 22, and the first intake part 30 is installed at the lower sidepump housing 23 of the auxiliary cylinder part 22a, and the first exhaust part 40 is installed atthe upper side pump housing 23 of the auxiliary cylinder part 22a. This is to prevent the gassupplied through the gas supply part 70 from being introduced into the cylinder part 22 forcompressing the incompressible fluid. Preferably, a volume of the auxiliary cylinder part 22ais formed larger than or the same as a volume in Which Water is pumped by the cylinder part22 and the piston 2la.
    MeanWhile, the gas supply part 70 serves to supply the gas to be compressed into thecylinder part 22 or the auxiliary cylinder part 22a, and has a gas supply hole 7l formed at thepump housing 23, and the gas supply hole is connected With a gas compressor 72 for supplying the gas to be compressed, or a gas tank and a gas supply pipe 73. A third check valve 75 which prevents the incompressible fluid from flowing back through the gas supplypart, when the piston 2la of the compression driving part 21 is moved forward, is installed atthe gas supply hole 7l. A supply pressure of the gas supplied through the gas supply pipe 73is not required to be relatively higher than a pressure which compresses the incompressiblefluid. The gas supply pipe may further include a pressing pump which is interlocked with thepiston of the compression driving part, and supplies the gas to be compressed.
    An incompressible fluid 100 which is circulated through the retum pipe 62, thecylinder part 22 and the supply pipe 6l is stored in the storage tank 60. The incompressiblefluid l00 may be a lubricating oil or water which reduces friction between the piston and thecylinder, but is not limited thereto.
    As illustrated in FIG. 2, the first check valve 3l installed at the first intake part 30includes a valve housing 33 having a valve seat part 32 installed at the first intake part 30 ofthe pump housing, a valve member 34 which is slidably installed at the valve housing 33 tocontrol supplying of the water in contact with the valve seat part 32, and a spring 35 which isinstalled between the valve member 34 and the valve housing 33 to elastically bias the valvemember 34 in a closing direction when the piston 2la moved along the cylinder part 22 ismoved forward.
    The second and third check valves 4l and 75 substantially have similar structure to thefirst check valve 3 l. The clo sing direction of the valve member in the second and third checkvalves 4l and 75 may be changed according to an operation state of the piston 2la which isreciprocated along the cylinder part 22.
    The storage tank 60 has an intemal space in which the incompressible fluid l00 andthe compressed gas are stored simultaneously. The compressed gas added to theincompressible fluid l00 is separated in the intemal space of the storage tank 60 due to a difference in a specific gravity. The incompressible fluid is stored at a lower side of the internal space of the storage tank 60, and the compressible gas is stored at an upper sidethereof. The storage tank 60 may further include a tank Which separately stores thecompressible gas.
    An operation of the gas buster having the above-described structure of the presentinvention Will be described.
    To compress the gas using the gas buster, the pump 20 is driven to pump theincompressible fluid 100 in the storage tank 60. Like this, the incompressible fluid l00 iscirculated from the storage tank 60 to the retum pipe 62, the first intake part 30, the cylinderpart 22, the first exhaust part 40, the supply pipe 6l and the storage tank 60.
    In this process, the gas to be compressed is supplied to the cylinder part 22 using thegas supply part 70. The supplied gas is added to the incompressible fluid l00 Which iscompressed in the cylinder part 22 or the auxiliary cylinder part 22a, and then pumped to thestorage tank 60 through the first exhaust part 40 and the supply pipe 6l.
    In the case in Which the incompressible fluid l00 is sucked by the piston 2la of thecompression driving part 2l, Which is reciprocated in the cylinder, even When thecompressible gas is supplied, the gas is moved toward the first exhaust part 40, and thus thecompressible fluid is not introduced into the cylinder part 22 as a substantial compressing areain Which the piston is reciprocated.
    When the lubricating oil is used as the incompressible fluid l00, a lubrication actionbetween the cylinder part and the piston may be activated and also may prevent thecompressible fluid from leaking through the compression driving part.
    The incompressible fluid l00 added to the gas as the compressible fluid is supplied tothe storage tank 60 through an exhaust port, and the compressible gas and the incompressiblefluid are separated in the intemal space of the storage tank 60 by the difference in the specific gravity. The separated gas is located at the upper side of the storage tank, and the incompressible fluid is located at the lower side thereof and then circulated as describedabove.
    As described above, the gas buster according to the present invention can add thecompressible gas to the incompressible fluid, can compress them, and then can separate themusing the difference in the specific gravity, thereby enhancing compression efficiency of thegas as the compressible fluid.
    Although a few embodiments of the present invention have been shown and described,it Would be appreciated by those skilled in the art that changes may be made in theseembodiments Without departing from the principles and spirit of the invention, the scope of Which is defined in the claims and their equivalents.
