Description
Technical field
The utility model relates to Diesel Engine Technique Field, particularly a kind of pressurization system applying to the two pressurized machine of output terminal on medium speed diesel.
Background technique
Pressurization system improves one of most effective measures of diesel engine power, has been widely used at present on locomotive, boat diesel engine.So-called supercharging, referring to the aeration quantity improving cylinder by improving diesel engine intake pressure, therefore, can correspondingly increase the amount of fuel spraying into cylinder, improves the mean effective pressure of diesel engine, thus effectively improves diesel engine power.My company newly-designed 12V280 marine diesel engine prototype is the 12V280 diesel engine that railway locomotive uses, and be equipped with 2 VTC254 exhaust gas turbine with axial flow pressurized machines, pressurized machine is placed on free end and the output terminal of diesel engine respectively.For the usage requirement on boats and ships, being again equipped with 2 VTR254 radial-flow exhaust turbochargers, for ease of coordinating the integral arrangement of watercraft engine room, requiring that 2 pressurized machines are arranged in the output terminal of diesel engine, so we have redesigned pressurization system again.
Model utility content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of pressurization system applying to the two pressurized machine of output terminal on medium speed diesel.
The technical solution adopted in the utility model is such:
A kind of pressurization system applying to the two pressurized machine of output terminal on medium speed diesel, comprise diesel-engine body, described diesel-engine body inside is divided into left and right two row and arranges 12 cylinders altogether, also comprise left pressurized machine, right pressurized machine, outlet pipe, air inlet three-way pipe, air inlet housing of intercooler and intercooler, described outlet pipe has two, every root outlet pipe collects the waste gas of a row cylinder and introduces corresponding left pressurized machine, in right pressurized machine, pressurized gas is passed into air inlet housing of intercooler by " Y " type air inlet three-way pipe by the left blower outlet adapter of described left pressurized machine and the right blower outlet adapter of right pressurized machine, after intercooler cooling, by the pressure stabilizer below it, gas is introduced each cylinder.
As preferably, described left pressurized machine and right pressurized machine arrange relief opening at top respectively, and exhaust ports is by the outer exhaust duct of exhaust expansion bellows junctor.Relief opening is arranged on pressurized machine top, arranging exhaust air pipeline in very convenient locomotive cabin, if relief opening to be arranged on other positions of pressurized machine, then very inconvenient.
As preferably, described left pressurized machine and right pressurized machine by pressurized machine support installing at diesel engine end of body.Further preferably, described pressurized machine support is reverse V-shaped, all downward-sloping 30 degree of its two plane of inclination.Further preferably, the left blower outlet direction of described left pressurized machine is for tilting upward 30 degree, and the right blower outlet direction of described right pressurized machine is for tilting upward 60 degree.Described diesel engine end of body also arranges thin slice Flywheel disc below pressurized machine support.
Two pressurized machines are VTR254 radial-flow type pressurized machine, are arranged in parallel at output terminal, and this pressurized machine, because of its tool stability, serviceability and versatility, is applicable to being assemblied in Marine Medium-speed Diesel Engine very much.Gas inlet housing, the compressor housings of VTR254 radial-flow type pressurized machine can carry out rotating of several angle relative to its exhausting waste gas housing (leg is assemblied on exhausting waste gas housing) with pressurized machine leg.Due to the 600kg that weighs of every platform pressurized machine, and when diesel engine runs, vibrations are comparatively large, and therefore, pressurized machine support should adopt high rigid material manufacture.In addition, the face under pressurized machine support Design two is tilted to and the blower outlet of pressurized machine are arranged obliquely, contribute to very much vacateing installing space in locomotive cabin, and do not affect the thin slice Flywheel disc below it.
As preferably, described outlet pipe comprise exhaust manifold and on exhaust branch pipe and bellows, described exhaust branch pipe has 6, is connected respectively with six cylinders of respective side, described exhaust manifold merogenesis manufacture and being connected by bellows between each joint.Because exhaust manifold volume is enough large, therefore the exhaust of each cylinder enters undergoes rapid expansion after exhaust manifold, and air pressure reduces to overpressure, and in house steward, pressure wave is small.When diesel engine stable operation, the pressure almost constant in exhaust manifold, two equal stable operations of pressurized machine.The structure that often saves can be made very simple for the segmented design of exhaust manifold and casting processing is easier, meanwhile, middlely adopts bellows to connect effectively to eliminate assembly error and exhaust manifold to be heated the flow of metal brought.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, compact and reasonable arrangement, does not have because the reason of pressurized machine is the width and the height that increase diesel engine;
2, parts ripe on original diesel engine are remained to greatest extent, mutual noninterference;
3, diesel exhaust enter the process of turbine and pressurization gas from blower outlet to intercooler in the process carrying out cooling all very smooth and easy, runner is also very short;
4, the amount of fuel spraying into cylinder can be increased, improve the mean effective pressure of diesel engine, thus effectively improve diesel engine power.
