The model utility content
The purpose of this utility model just provides a kind of diesel engine, casts easy to processly, and maintenance is convenient, has reduced cost, can realize both-end output, has realized a tractor serves several purposes, satisfies more user's request, can address the above problem fully.
The purpose of this utility model realizes by following technical proposals:
A kind of diesel engine, comprise head end box, described head end box mainly is made of pump supporting box and intercooler case, and the free end face of pump supporting box is provided with high-temperature water pump, low temperature water pump, for subsequent use mouthful of high-temperature water pump, for subsequent use mouthful of low temperature water pump, oil pump and front end power stage port.
The head end box of this diesel engine partly is to be combined by pump supporting box and intercooler case, has greatly simplified interior oil water cavity road, has brought convenience for casting and processing, has simplified mould and cutter, has reduced the manufacturing cost.Front end power stage port can be realized smaller power output (the most about 200kw), thereby has realized both-end output, can satisfy the requirement of different user.The setting that exposes setting and high and low temperature water pump mouth for subsequent use of high and low temperature water pump can be designed to cooling water system mixed cycle or high and low temperature independent loops according to customer requirements, can satisfy more user's request.
Further, pressure transducer before the intercooler also is installed behind Oil Outlet Temperature sensor, lubricating oil outlet pressure sensor, the high-temperature water pump before the intercooler behind the temperature transducer and high-temperature water pump on the described pump support box.
The operation of diesel engine can be more effectively controlled in the setting of these sensors.
Further, be arranged with intercooler air inlet gas collecting box and the intercooler gas collecting box of giving vent to anger on the described intercooler case.
The intercooler of this structure gas collecting box of giving vent to anger plays the effect of pressure stabilizer, has guaranteed the conformity of each cylinder inlet and outlet.
Further, lubricating oil pump export pipeline, lubricating oil pump inlet ductwork, lubricating oil pump outlet pressure regulator valve, lubricating oil pump outlet non-return valve, main oil gallery import pressure regulator valve, main lubricating oil pump fuel sucking pipe oil outlet and the import for subsequent use of safety check outlet end also are installed on the described pump supporting box.
Import arranges common pressure regulator valve and compares with main oil gallery with the outlet of the diesel engine lubricating oil pump of prior art, and this diesel engine arranges separately lubricating oil pump outlet pressure regulator valve and main oil gallery import pressure regulator valve, and the independent independent pressure of controlling is separately controlled more accurate convenience respectively.Main lubricating oil pump fuel sucking pipe oil outlet and the import for subsequent use of safety check outlet end also are set, so that use for diesel engine increases lubricating oil pump for subsequent use when non-dredge pump main frame, widen its using scope.
Further, the monnolithic case of described diesel engine is of a size of long 4031mm, wide 1520mm, high 2900mm.
The boundary dimension of this diesel engine is that long 4305mm, wide 1812mm, high 3245mm are less than the boundary dimension of prior art diesel engine, not only saves to take up room, and is conducive to for land container-type generator set.
Compared with prior art, the beneficial effects of the utility model are:
1. the length size of this diesel engine all significantly reduces, conserve space not only, and for preparing with the container-type generator set in the land;
2. be provided with front end power stage port (PTO) at free end, be connected with bent axle by this port, can realize the output (the most about 200kW) of smaller power, thereby realize both-end output, can satisfy the requirement of different user;
3. the setting of for subsequent use mouthful of high-temperature water pump and low temperature water pump mouth for subsequent use makes diesel engine both can be used for engineering ship, also can be used for promoting mainly ship, also can be used for the land generating, even also can be used for locomotive, realizes a tractor serves several purposes;
4. the setting that exposes setting and high and low temperature water pump mouth for subsequent use of high and low temperature water pump can be designed to cooling water system mixed cycle or high and low temperature independent loops according to customer requirements, can satisfy more user's request;
5. in the control system, pressure transducer before the intercooler is set behind Oil Outlet Temperature sensor, lubricating oil outlet pressure sensor, the high-temperature water pump before the intercooler behind the temperature transducer and high-temperature water pump, can more effectively controls the operation of diesel engine;
6. head end box is arranged to split type module, be pump supporting box and intercooler case, and the profit cavity of simplifying, bring convenience for casting and processing, can simplify mould and cutter, indirectly reduce cost, and maintenance is convenient, can satisfy again simultaneously the requirement of 6～9 cylinder diesels, except pressurized machine and main lubricating oil pump, head end box and annex can exchange in the NY210 serial diesel engine;
7. maintenance and easy for installation has reduced again cost simultaneously.
