Below in conjunction with each accompanying drawing, working principle of the present invention is described:
Referring to Fig. 1, ram 8 and air cylinder 12 are integrated on the same bent axle 45, and ram 8 is by dynamic link 37 subtend crankshaft outputs; Air cylinder 12 is by obtaining power with crossing the connecting rod 40 of calming the anger to bent axle 45.The former sends to such an extent that power equals the power sum that latter's power absorbed and camshaft 11, oil pump 33 consume.
On the basis of Fig. 1 referring to Fig. 2, described ram 8 working principles are: when power piston 43 is descending, overhead camshaft 11 makes that intake valve assembly 18 is opened, exhaust valve assemblies 49 is closed, form negative pressure in the ram 8, air 19 enters in the ram 8 through air-strainer 68, turbosupercharger 70, ram suction tude 48, ram intake manifold 62, the ram gas-entered passageway 20 that is in the cylinder cap 4, and this moment, ram 8 was in aspirating stroke; Power piston 43 leaves after bottom dead center, and camshaft 11 is closed intake valve assembly 18, and power piston 43 is up, air in the compression cylinder, and ram 8 is in compression stroke; In power piston 43 certain position near top dead center, fuel supplying device 9 infeeds fuel in ram 8, naturally or by the igniting facility light in the gas of fuel after compression heats up, the fuel combustion release heat forms high temperature, hyperbaric environment in cylinder, high-pressure air propulsion power piston 43 is descending, and ram 8 is in expansion stroke; When power piston 43 cross lower dead center once more, when moving upward, camshaft 11 is opened exhaust valve assemblies 49, move upward by power piston 43, waste gas in the firing chamber is pushed out to ram exhaust passage in the cylinder cap 4 through exhaust valve assemblies 49, and arrange pipeline downstream through ram gas exhaust manifold 63, ram outlet pipe 51, this moment, ram was in exhaust stroke, for next work cycle is prepared.Whole process is equivalent to present quartastroke engine.Power piston 43 promotes bent axles 45 rotations by dynamic link 37 in expansion stroke, outwards send power, other three strokes then rely on absorption from the power of bent axle 45 to keep the continous-stable running of whole power section.Ram 8 is whenever finished a circulation, 720 ° of bent axle 45 rotations.
On the basis of Fig. 1 referring to Fig. 3, described air cylinder 12 working principles are: when displacer 41 moves downward, overhead camshaft 11 makes that suction valve assembly 13 is opened, outlet valve 52 is closed, form negative pressure in the air compressing cylinder 12 at this moment, air 15 enters in the air cylinder 12 through air cleaner 69, air cylinder suction tude 47, air cylinder intake manifold 59 and the air cylinder gas-entered passageway 16 that is in the cylinder cap 4, and this moment, air cylinder was in aspirating stroke; Cross after bottom dead center at displacer 41, camshaft 11 makes that suction valve assembly 13 is closed, outlet valve 52 is opened, along with displacer is up, with the air compression in the air cylinder 12, and be pushed into the exhaust passage that is in the cylinder cap 4 through outlet valve 52, arrange pipeline downstream by air cylinder gas exhaust manifold 61 and air cylinder outlet pipe 50, this moment, air cylinder was in exhaust stroke.Displacer 41 in the inlet and outlet stroke to cylinder in gas acting, institute's consumed power by the connecting rod 40 of calming the anger from bent axle 45.Whenever finish a circulation, 360 ° of crankshaft rotating.
Whole air compressor in service has only ram 8 outwards to send power in expansion stroke, and all two strokes of other three strokes of ram 8 and air cylinder 12 all rely on and consume external power and be maintained.The flywheel assembly 1 that plays the energy storage effect has enough rotary inertias, with ram 8 unnecessary power absorption and storing in expansion stroke, remedy the energy that air compressor is consumed in other stroke, keeping entire equipment can run well, and the fluctuation of speed that makes bent axle 45 is controlled in the allowed band, to guarantee entire equipment work smoothness.
Air can elevated temperature in cylinder during by Piston Compression, and what high temperature and high pressure environment, ram 8 sealed in the cylinder in expansion stroke also is the combustion gas of High Temperature High Pressure, and the low temperature component that high temperature and high pressure gas can be in contact with it towards periphery transmit heat.For the temperature that makes each parts is unlikely to too high, and influence the functional reliability and the life-span of whole air compression system.And, the too high air inlet coefficient that also can reduce each cylinder of the temperature at these positions, the working efficiency of reduction gas compressor.So cool off at these positions of reply: allow the lower cooling water of temperature from low temperature water pipe 27 be pumped into each power cylinder sleeve 17 body 2, in the cooling jacket 42 of cylinder sleeve 31 peripheries of calming the anger, cylinder sleeve 17,31 is cooled off, cooling water is by cylinder pad 3 afterwards, enter and be arranged on each ram suction tude 48, outlet pipe 51 in the cylinder cap 4, cooling jacket 10 with around each air cylinder suction tude 47, the outlet pipe 50 cools off these positions.Cooling water has absorbed heat by high temperature position is cooled off in flow process, self temperature raises, and becomes the high-temperature water that does not have cooling capacity, goes out cylinder cap 4 backs and enters radiator 25 by high-temperature water pipeline 23.Under the forced convection of radiation fan 24, radiator 25 cools off high-temperature water the low temperature water that becomes to have cooling effect, be pumped into cooling jacket 10 in cooling jacket 42 in the body 2, the cylinder cap 4 once more,, the temperature of each high-temperature component be in the suitable scope by circulation like this.
Bent axle 45 is by being installed in a belt wheel 29 and timing gear 57 external output powers of same end.Belt wheel 29 drives radiation fan 24 by belt 28, and tension device 26 can be regulated rate of tension to drivign belt 28.The situation of timing gear 57 drive cam shaft 11, oil pump 33 can be with reference to figure 4: timing gear 57 drive by 30 pairs of Oil pump drive gears 58 of timing tooth form synchronous belt and camshaft power input timing gear 55, and gear 55 so drive timing transition gear 54 coaxial mounted with it with same rotation speed operation, the timing camshaft actuation gear 53 of drive installation on every camshaft 11, drive camshaft 11 runnings, the generation corresponding action of each inlet and exhaust valve (valve) assembly under action of cam., bent axle identical because of the rotating speed of two camshaft 11a, 11b is 2: 1 with the ratio of the rotating speed of camshaft, so the ratio of crankshaft timing gear 57 and the rotating speed of camshaft actuated timing gear 53 is 2: 1.
The suction tude of ram 8 and air cylinder 12 is installed in the homonymy of cylinder cap 4, rob the gas phenomenon for fear of the two adjacent cylinder of the same suction tude of correspondence when the air inlet and influence the air inlet effect, the phase place of this two cylinder should stagger as far as possible, and avoids the two adjacent cylinder inlet open time of shared same suction tude overlapping phenomenon to occur as far as possible.
For the running that makes air compressor smooth-going, reduce vibration, except the firing interval of each ram 8 is even as far as possible, the firing interval angle equals outside 720 ° of numbers divided by ram as far as possible, also should with ram 8 and air cylinder 12 along the bent axle axial distribution evenly, symmetric arrangement, the phase angle between the adjacent air cylinder of two phase place should equal 360 ° of numbers divided by air cylinder as far as possible.
Referring to Figure 11, in order to improve the air inlet effect of ram 8, the exhaust of ram 8 is carried out supercharging to improve its volumetric efficiency by 70 pairs of ram air inlets of turbosupercharger 19, increases the power that ram unit's discharge capacity is sent, and is equivalent to power section is strengthened.The provided upstream of compressor turbine has air-strainer 68, to guarantee the clean degree of ram 8 air inlets; The downstream of gas turbine is provided with tail-gas after treatment apparatus 71, to reduce the pollution of ram tail gas to environment.And there are two inlets the suction tude upstream of air cylinder 12: one the air compressor of having contacted on it starts Auxiliary valves 80 from the air cleaner 69 that leads to atmosphere, and another which is provided with air compressor starting valve 79 from air compressor starting high-pressure air storage tank 78; The outlet pipe downstream of air cylinder 12 then is provided with three valves in parallel, and its effect is outwards to export high-pressure air or air compressor is started smoothly.
During the air compressor starting, open pressure-relief valve 76, make the pressure in the outlet pipe identical with atmosphere.Close air compressor starting gas storage valve 74, high-pressure air delivery valve 75, air compressor starting Auxiliary valves 80, and unlatching air compressor starting valve 79, because the suction valve 13 and the outlet valve 52 of any one air cylinder 12 can not be in opening state simultaneously, and, always there is the air inlet valve position of at least one air cylinder to be in closed condition in opening state and outlet valve concerning with plural air cylinder.To make like this and enter in the air cylinder 12 by air cylinder suction tude 47 from the high-pressure air in the air compressor starting gas holder 78, it is descending to promote displacer 41, drive bent axle 45 rotations by the connecting rod 40 of calming the anger, and then power piston 43 is moved in ram 8, make it can finish a series of processes such as ignition, acting, enter the recurrent state of external acting smoothly.In case air compressor starts successfully, can close pressure-relief valve 76, air compressor starting valve 79, open air compressor starting Auxiliary valves 80, and air compressor starting gas storage valve 74 is to 78 inflations of air compressor starting high-pressure air storage tank, and perhaps high-pressure air delivery valve 75 inflate in gas holder 77 also outwards provides high-pressure air.
During compressor operation, earlier by opening air compressor starting gas storage valve 74, close high-pressure air delivery valve 75, pressure-relief valve 76 and air compressor starting valve 79, make in the air compressor starting high-pressure air storage tank 78 and charge into high-pressure air, just can close air compressor starting gas storage valve 74 afterwards, keep pressure-relief valve 76 to close to enough pressure, open high-pressure air delivery valve 75, in gas holder 77, charge into air,, promptly can outwards supply the high-pressure air of steady pressure to rated pressure.
Referring to Figure 12, the present invention also can have another embodiment, the difference of itself and scheme one is: 1. cancel turbosupercharger 70, on two kinds of gas exhaust pipings of the ram 8 and the exhaust casing 12 of calming the anger, heat exchanger 83 is set, utilize the higher ram exhaust 72 of temperature, air cylinder exhaust 73 is heated, directly utilize the waste heat in the ram exhaust, to satisfy those have temperature requirement to high-pressure air use occasion.2. the exhaust 72 of air cylinder 12 is divided into two branches arranged side by side on pipeline: one by heat exchange valve 81, and the heat exchanger 83 of polyphone with it; Another is by bypass valve 82.Can conveniently control the amount of the ram exhaust that enters heat exchanger 83 by the aperture of fit adjustment heat exchange valve 81 and bypass valve 82 like this, and then convenient temperature of regulating the high-pressure air of exporting.
Based on the above, the present invention is a self-driving type high-efficiency compact integral air compressor, and its beneficial effect comprises:
(1) owing to the present invention power section and pneumatics partial fusion are in the same place, rather than as traditional air compressor, drive by extra power engine, thereby reduced a lot of supplementary equipment, so compact structure of the present invention, occupation area of equipment is little, be convenient to operation and control, when the high-pressure air of same amount was provided, the reciprocating air compressor gross mass that the present invention is general traditional was light by about 30%, can save raw material and manufacture cost.
(2) do not exist among the present invention between the power engine of traditional compressor and the working machine special power transmission mechanism must be set, as belt, chain, coupling etc. so there be not loss and the fault that causes because of transmission of power in the present invention, have improved energy utilization efficiency and reliability.
(3) the present invention is because with designing two portions together, can try to carry out between power section and the air compression part reasonable optimizing coupling more, effectively overcome the problem that conventional piston formula air compressor and power engine are difficult for coupling, both improve the life-span and the utilization ratio of equipment, also improved energy utilization efficiency.
(4) in general, large air compressor is as driving with internal-combustion engine, then need special starter motor to start, for example motor or compact internal combustion engine etc., and the present invention is because with power section with calm the anger be partially integrated on the same bent axle high-pressure air of storing before can importing during starting in air cylinder, drive ram with air cylinder, successfully light a fire, start until power section,, save equipment cost so the present invention need not special starter motor.
(5) air compressor is not running at full capacity in a lot of occasions and time, also promptly many times the use amount of high-pressure air is littler than the specified air demand of air compressor, and frequently starting and stopping of power engine, so generally the gas compressor exhaust is led directly to atmosphere by Decompression valves, be gas compressor idle running and pressurized gas not, power engine is in very little load and approaches idling mode like this, and idling oil consumption rate height especially changes the occasion that rises and falls very greatly in those high pressure air use amounts for a long time.And compare with traditional gas compressor, the ram quantity of the present invention during because of idling is few, so the idling oil consumption reduces, and then saves user cost,
(6) if traditional reciprocating air compressor adopts internal combustion engine drive, then the power section and the part of calming the anger all respectively have a cover cooling system, lubrication system, control system etc.But these systems all have only a cover in the present invention, so present device is simple relatively, supplementary equipment is few relatively, have reduced the maintenance cost of fault odds and equipment.
(7) temperature of high-pressure air provided by the invention can be regulated in certain scope, this has the use occasion of higher temperature requirement to those high-pressure airs, for example carry source of the gas, adopt the present invention can save lot of energy as strength with protection against the tide, insulation requirement, and warming-up device.
(8) help air-pressure equipment to intelligent, integrated direction development.Compact structure of the present invention, volume are little, supplementary equipment is few relatively, it is integrated with each function systems such as air compressor, automatic controller, manipulators to be highly advantageous to, make have only the low pressure gas inlet opening, the integrated type high-pressure air supply station of high pressure air delivery outlet, fuel inlet and minority operating button.
