Abstract
The utility model discloses a water taking structure for an EGR (exhaust gas recirculation) cooler of a diesel engine, and the water taking structure is described with following accompanying drawings. The water taking structure for the EGR cooler of the diesel engine has the technical scheme that a water taking connection base is provided with a flange connector, and the outer periphery at the top end of a water taking pipe is bulged. A flange of the water taking connection base is fixed with the bottom of a water chamber wall of an oil cooler of a machine body, and the water taking pipe is connected to the EGR cooler above the machine body through a rubber hose. A sealing gasket is arranged between the flange connector of the water taking connection base and the water chamber wall of the oil cooler; two ends of the rubber hose are respectively fixed with the top end of the water taking pipe and a water inlet of the EGR cooler through dual-steel wire hoops. The water taking connection base is simple in structure and low in manufacturing cost. The water taking connection base is arranged below the EGR cooler and can take water from the bottom end of the water chamber wall of the oil cooler, the circulation path of cooling water can be enabled to be reasonable, the water taking rubber hose is shorter, and the layout is compact.
Description
Technical field
The utility model belongs to internal combustion engine component, is specifically related to the water intaking constructional device of diesel exhaust recycle cooler.
Background technique
At present domestic and international environmental regulation increasingly stringent, the control of dual fuel of diesel engine is also more and more stricter.The strict development that has also promoted motor machine emission control technique of law.Control the most typical measure of discharging and install exactly EGR (EGR) system additional, just need to increase in the engine body outside by a cover cooling unit for this reason.Due to the impact that arranged by the diesel engine space outerpace, the layout of different model diesel engine EGR system is different, and its water intaking structure is also different.Large multi-model is fetched water in body cylinder sleeve water cavity, the defect of this method is that the body producting process difficulty is larger, and cost is also higher; Simultaneously, the water intaking path is far away, and the pipeline more complicated, make efficiency lower.The water intaking structure that the utility model proposes has successfully solved this technical barrier.
Summary of the invention
The purpose of this utility model is, provides that a kind of body water intaking position is reasonable, path is short, can improve the cooler for recycled exhaust gas water intaking structure of efficiency of producing drinking water.
Below in conjunction with accompanying drawing, structural principle of the present utility model is described.Diesel exhaust recycle cooler water intaking structure, its technological scheme is: the water intaking joint chair is provided with flange-interface, intake pipe top external diameter projection.The machine oil cooler water cavity wall bottom of the flange of water intaking joint chair and body is fixing, and intake pipe is connected on the cooler for recycled exhaust gas of body top by sebific duct.
Characteristics of the present utility model are, the water intaking joint chair is simple in structure, and manufacture cost is lower.The water intaking joint chair is arranged in the cooler for recycled exhaust gas below, and the bottom water intaking from machine oil cooler water cavity wall, can guarantee that the cooling water circulation path is reasonable, and makes the water intaking sebific duct shorter, compact in design.
Description of drawings
Fig. 1 is the utility model water intaking joint chair construction profile figure.
Fig. 2 is the utility model linkage structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, principle of the present utility model and structure are further described.Diesel exhaust recycle cooler water intaking structure, its structure are that water intaking joint chair 1 is provided with flange-interface, intake pipe top external diameter projection (as Fig. 1).The machine oil cooler 3 water cavity walls bottoms of flange and the body 2 of water intaking joint chair are fixing, and intake pipe is connected on cooler for recycled exhaust gas 5 above body (as Fig. 2) by sebific duct 4.
Be provided with the sealing gasket sealing between water intaking seat-joined flange interface and machine oil cooler water cavity wall; The two ends of sebific duct adopt two steel wire hoops to fix with intake pipe top and described cooler for recycled exhaust gas water inlet respectively.
The water intaking joint chair directly is connected with machine oil cooler water cavity wall, for preventing that cause sebific duct to become flexible comes off because the rhythm of engine is higher, so intake pipe top external diameter is processed as protruding structure.The water inlet of cooler for recycled exhaust gas is taken from the machine oil cooler water cavity, then by sebific duct, is connected to cooler for recycled exhaust gas, can guarantee that like this path of cooling water circulation is the most reasonable, and makes the water intaking sebific duct also shorter, reaches compact in design and the purpose of efficiently fetching water.
Claims (2)
1. diesel exhaust recycle cooler water intaking structure, the joint chair (1) that it is characterized in that fetching water is provided with flange-interface, intake pipe top external diameter projection, machine oil cooler (3) the water cavity wall bottom of the flange of water intaking joint chair and body (2) is fixing, and intake pipe is connected on the cooler for recycled exhaust gas (5) of body top by sebific duct (4).
2. according to diesel exhaust recycle cooler water intaking structure claimed in claim 1, it is characterized in that between described water intaking joint chair (1) flange-interface and described machine oil cooler (3) water cavity wall being provided with the sealing gasket sealing, the two ends of described sebific duct (4) adopt two steel wire hoops to fix with intake pipe top and described cooler for recycled exhaust gas (5) water inlet respectively.
