Abstract
The utility model discloses a water-cooled supercharger system for a gas engine. A supercharger is fixed at the outer end of an exhaust pipe; an oil inlet pipe of the supercharger is connected to an oil filter outside a supercharger body; an oil return pipe is tightly attached to the outer wall of an engine body, and is connected to the oil port of a crankcase; a water inlet pipe of the supercharger is connected to a water inlet at the end of the engine body from the upper space of a cylinder cover; and a water return pipe and an oil return pipe are sequentially connected to a water return port below the engine body. The specific heat of water is greater than that of oil, so that a water cooling effect is remarkably better than an oil cooling effect on the supercharger, but the key problem is the way for arranging a water cooling component attached to the supercharger on the engine body. In the setting, the water return pipe and the oil return pipe of the supercharger are tightly attached to the engine body, and other components are arranged in spaces on the upper part or two end parts of the engine body, so that the structure is very compact. Therefore, the problems of high heat load, high exhaust gas temperature and the like of the gas engine are effectively solved, and the dynamic property and economic efficiency of an internal combustion engine are enhanced.
Description
Technical field
The utility model belongs to engine components, is specifically related to a kind of supercharger systems device that is used for the gas engine cooling.
Background technique
The pressurized machine that present gas engine is used is the pressurized machine of oil lubricating cooling, and the delivery temperature of gas engine is very high, and heat load is also big.After oil temperature raises in engine operation process, influence lubrication effect, make pressurized machine burn reduction pressurized machine working life easily because of its viscosity descends.When influencing the radiating effect of motor, also reduced the output power of motor, will influence the working life of motor when more serious.If adopt the water cooling effect better, but to relate to the compactedness difficult problem of water-cooled supercharger systems device arrangements.Proposition of the present utility model can effectively address the above problem.
Summary of the invention
The purpose of this utility model is to provide a kind of water-cooled pressurized machine to be connected with gas engine, solution excessive discharge temperature, the problem that heat load is big.
Below in conjunction with accompanying drawing theory structure of the present utility model is described.Gas engine water-cooled supercharger systems comprises: pressurized machine, flange, outlet pipe, oil inlet pipe, return tube, engine body, pressurized machine intake pipe, cylinder cap, water intake, return pipe and backwater mouth etc.In order to guarantee the best cooling performance and the compactedness of structure, its technological scheme is: pressurized machine is fixed in the outlet pipe outer end by special flange, and oil inlet pipe is located at the left surface of pressurized machine, and the pressurized machine return tube is connected to the crankcase hydraulic fluid port of engine body bottom.The water intake pressurized machine water outlet that the pressurized machine intake pipe is connected to the cylinder cap right-hand member is positioned at pressurized machine return opening top, is connected to backwater mouth below the engine body by return pipe.Because specific heat of water is greater than the specific heat of oil, so select for use its effect of water-cooled obviously greater than oil cooling to pressurized machine, key issue is exactly how the incidental water-cooled parts of pressurized machine are arranged on the engine body.Pressurized machine is fixed in the outlet pipe outer end, and will guarantees distance between pressurized machine and the outlet pipe less than 10cm-30cm, just unaffected during the car load assembling.This is provided with can find out obviously that the return pipe of pressurized machine and return tube be close to engine body, and other parts are provided with all in the space of body upper or two ends, so structure is very compact.
Characteristics of the present utility model and beneficial effect are: most heat is taken away by cooling water after adopting the water-cooled supercharger systems, guarantee pressurized machine energy proper functioning, thereby efficiently solve problems such as the gas engine heat load is big, delivery temperature height, the utility model has been developed the potential of pressurized machine, can improve the power character and the Economy of explosive motor simultaneously.
Description of drawings
Shown in accompanying drawing be that the utility model structure is formed schematic representation.
Embodiment
Below in conjunction with accompanying drawing and by embodiment composition structure of the present utility model is further described.The concrete structure of gas engine water-cooled supercharger systems is: pressurized machine 1 is fixed in outlet pipe 3 outer ends by special flange 2, and oil inlet pipe 4 is located at the left surface of pressurized machine 1, and pressurized machine return tube 5 is connected to the crankcase hydraulic fluid port of engine body 6 bottoms.The water intake 9 pressurized machine water outlets that pressurized machine intake pipe 7 is connected to cylinder cap 8 right-hand members are positioned at pressurized machine return opening top, are connected to backwater mouth 11 below the engine body 6 by return pipe 10.The waist of pressurized machine 1 is fixing with spiral case 13 with special fixture 12.The oil inlet pipe of pressurized machine connects certainly in extra-organismal oil filter; Return tube is close to the engine body outer wall and is connected to the crankcase hydraulic fluid port.The intake pipe of pressurized machine is connected to the water intake of engine body termination from the cylinder cap upper space; Return pipe and return tube direct motion are connected to the backwater mouth (as figure) below the engine body.
Present embodiment is applied to the 4D125-N3 diesel engine, compares with water cooling plant of the same type after adopting the water-cooled supercharger systems, and high exhaust temperature is reduced to 620 ℃ by 730 ℃, and lubricating oil temperature is reduced to 92 ℃ by 112 ℃.This type is matched with the KLQ6758 passenger vehicle, and has carried out 45000 kilometers roadway experiments.The proof pressurized machine can be worked under good environment, and the temperature of machine oil is reduced, and has strengthened the lubrication effect of machine oil.
