Abstract
The invention discloses a double-shaft balance single cylinder diesel engine with a fuel delivery pump. The double-shaft balance single cylinder diesel engine comprises a gear chamber. The fuel delivery pump is connected with the right end of the gear chamber in a sleeving mode. One end of a fuel delivery pump plunger is connected with an inner cavity of the fuel delivery pump in a clamped mode, and the other end of the fuel delivery pump plunger extends into an inner cavity of the gear chamber. An eccentric wheel is attached to the outer wall of the fuel delivery pump plunger. The eccentric wheel is installed at the front end of a balance shaft gear, and both the eccentric wheel and the balance shaft gear are installed in the inner cavity of the gear chamber. The double-shaft balance single cylinder diesel engine with the fuel delivery pump is simple in structure. The eccentric wheel is added to the front end of the balance shaft gear arranged on one side of the double-shaft balance single cylinder diesel engine, and the eccentric wheel drives the fuel delivery pump plunger located on the gear chamber to move during operation of the diesel engine, so that the requirements for absorbing diesel oil into the fuel delivery pump from a diesel oil filter and providing the diesel oil for a diesel engine fuel injection pump pipeline are met. Accordingly, the oil absorbing capacity of a fuel injection pump is improved and a single cylinder diesel engine oil way oil supply system is improved.
Description
Technical field
The present invention relates to the single cylinder diesel technical field of double-shaft balance, be specially a kind of double-shaft balance single cylinder diesel with oil transfer pump.
Background technique
Existing single cylinder diesel oil transportation promotes injection pump plunger by the cam of injection pump on camshaft, and the vacuum relying on plunger to be formed is come from outside oil suction, therefore must accomplish when using diesel engine: 1, the maintenance of oil circuit is unimpeded; 2, when increasing the filter member such as diesel-oil filter, Injection Pump will have great oil absorption; 3, diesel oil tank placement location is higher than the position of the Injection Pump of diesel engine.According to above situation, when using for reference multi-cylinder diesel engine oil supply system, in order to the fuel system of Optimization of Diesel Engine, therefore provide a kind of double-shaft balance single cylinder diesel with oil transfer pump.
Summary of the invention
The object of the present invention is to provide a kind of double-shaft balance single cylinder diesel with oil transfer pump, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technological scheme: a kind of double-shaft balance single cylinder diesel with oil transfer pump, comprise gear chamber, the right-hand member of described gear chamber is socketed with oil transfer pump, and oil transfer pump communicates with gear chamber, the inner chamber of described oil transfer pump is connected with one end of oil transfer pump plunger, and the other end of oil transfer pump plunger extends to the inner chamber of gear chamber, and the outer wall of oil transfer pump plunger is fitted with eccentric wheel, described eccentric wheel is arranged on the front end of balance shaft gear, the axle core of described eccentric axle core and balance shaft gear is positioned at same position, and eccentric wheel and balance shaft gear are installed in the inner chamber of gear chamber.
Preferably, the oil outlet place of described oil transfer pump is also provided with filtering device for diesel.
Preferably, described filtering device for diesel is formed by stacking by filter paper used in fuel filter is corrugated.
Compared with prior art, the invention has the beneficial effects as follows: the double-shaft balance single cylinder diesel structure of this band oil transfer pump is simple, increase by an eccentric wheel in balance shaft gear front end, double-shaft balance single cylinder diesel side, diesel engine eccentric wheel in operation process promotes the oil transfer pump plunger motion in gear chamber, thus reach diesel oil is sucked in oil transfer pump from diesel-oil filter, then to the requirement of diesel injection pump pipeline fuel feeding; Thus improve the oil absorption of Injection Pump, improve single cylinder diesel oil circuit oil supply system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 gear chamber, 2 balance shaft gears, 3 eccentric wheels, 4 oil transfer pumps, 5 oil transfer pump plungers.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the invention provides a kind of technological scheme: a kind of double-shaft balance single cylinder diesel with oil transfer pump, comprise gear chamber 1, the right-hand member of gear chamber 1 is socketed with oil transfer pump 4, and oil transfer pump 4 communicates with gear chamber 1, the oil outlet place of oil transfer pump 4 is also provided with filtering device for diesel, and filtering device for diesel is formed by stacking by filter paper used in fuel filter is corrugated.Filtering device for diesel can impurity further in filtering diesel oil, ensure the quality of diesel oil, the inner chamber of oil transfer pump 5 is connected with one end of oil transfer pump plunger 5, and the other end of oil transfer pump plunger 5 extends to the inner chamber of gear chamber 1, and the outer wall of oil transfer pump plunger 5 is fitted with eccentric wheel 3, eccentric wheel 3 is arranged on the front end of balance shaft gear 2, the axle core of eccentric wheel 3 and the axle core of balance shaft gear 2 are positioned at same position, and eccentric wheel 3 and balance shaft gear 2 are installed in the inner chamber of gear chamber 1, increase by an eccentric wheel 3 in balance shaft gear 2 front end, double-shaft balance single cylinder diesel side, the oil transfer pump plunger 5 that diesel engine eccentric wheel 3 in operation process promotes in gear chamber 1 moves, thus reach diesel oil is sucked in oil transfer pump 4 from diesel-oil filter, again to the requirement of diesel injection pump pipeline fuel feeding, thus improve the oil absorption of Injection Pump, improve single cylinder diesel oil circuit oil supply system.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
