Description
Technical field
What the present invention proposed is the improvement type of the diesel engine in dynamic power machine field, specifically a kind of unit three oil-pump diesel engines.
Background technique
Before the present invention proposes, the outputting power of ordinary diesel oil machine has rating value, and the size of output power is adjusted by the oil inlet quantity of throttle, this by accelerator open degree and very difficult grasp of oil pump oil inlet quantity adjusting diesel engine output power, its reason is, the diesel engine of a rated output power has an oil pump, so, when requiring output power to change, there is not special oil-flow control apparatus to operate.For example rated output power is that 14.7 kilowatts use for diesel engine is when drawing water, then with 14.7 kilowatts of outputs of rated power, and when needing it to be used as the farmland and to spray medicine, then need 4.3 kilowatts, even throttle is turned down, also will under same power, move, therefore oil supply is large, use uneconomical, so a peasant household need to be equipped with several the diesel engines that power is different.
According to the structural feature of real diesel engine use condition and existing diesel, exist output power and regulate the shortcoming that is difficult to accurate grasp, oil consumption greatly and uses inconvenience.
Summary of the invention
For the existing shortcoming of existing diesel with to the needs of many occasions of diesel engine power stage and the expectation of energy-conserving and environment-protective, the invention provides a kind of unit three oil-pump diesel engines.This motor utilizes three Injection Pumps of capable of regulating gear to regulate the diesel engine oil inlet quantity, solves the technical problem that diesel engine adapts to different capacity output needs.
The scheme that technical solution problem of the present invention adopts is:
At diesel engine three oil pumps are installed, the diesel oil output tube of each oil pump interconnects, and forms the threeway fuel supply line, is connected with the diesel engine filler opening; Opposite side at oil pump is equipped with oil pump tappet and roller, and the oil pump tappet contacts with very plate on being installed in camshaft and is connected, at an end of camshaft camshaft gear wheel is installed, and very the plate opposite side is coupling tactile the connection with convex-concave, and the convex-concave axle is provided with the breach of convex-concave; The convex-concave axle is installed on the convex-concave shaftgear, and be connected with a joggle with adjusting gear, adjusting gear is installed on the axle of regulating positioning wheel, in a side of axle positioning wheel is installed, positioning wheel is provided with locating slot, and adjusting gear is connected with the adjusting handle by stay cord with a side of the installation shaft of positioning wheel.
Good effect, because the oil pump of three different fuel deliveries is installed on the diesel engine of the present invention, oil pump makes one of them operation of oil pump by the adjusting of positioning wheel position, output and the corresponding output power of oil inlet quantity.With compare by the diesel engine of Throttle Opening Control oil inlet quantity, fuel-economizing is more than 30%, and has fuel-economizing, environmental protection, minimizing carbon emission, saves economic input and the convenient characteristics of using.Use on the suitable diesel engine as becoming power applications.

Embodiment
According to the figure, at diesel engine three oil pumps 2 are installed, the diesel oil output tube of each oil pump interconnects, and forms threeway fuel supply line 1, is connected with the diesel engine filler opening; Opposite side at oil pump is equipped with oil pump tappet 3 and roller 4, the oil pump tappet contacts with very plate 7 on being installed in camshaft 6 and is connected, end at camshaft is equipped with camshaft gear wheel 5, and very the plate opposite side is connected with 8 contacts of convex-concave axle, and the convex-concave axle is provided with the breach of convex-concave; The convex-concave axle is installed on the convex-concave shaftgear 9, and be connected with a joggle with adjusting gear 12, adjusting gear is installed on the axle of regulating positioning wheel 11, side at axle is equipped with positioning wheel 10, positioning wheel is provided with locating slot 13, and adjusting gear is connected with adjusting handle 14 by stay cord with a side of the installation shaft of positioning wheel.
What Fig. 2 was represented is middle oil pump work state.
What Fig. 3 was represented is upside operation of oil pump state.
Thereby the position of regulating positioning wheel according to pull handle changes convex-concave axle breach and the relative position of enduring plate, make the oil pump oil spout action of one of three oil pumps, the oil inlet quantity of three oil pumps is made as respectively large, medium and small three fuel injection quantitys, changes the output power of diesel engine with the oil inlet quantity of regulating diesel oil.
Working procedure of the present invention
The threeway fuel supply line is connected with the filler opening of diesel engine, and for diesel engine provides fuel oil, the discharge pressure of fuel oil realizes that by the oil pump to-and-fro motion action of oil pump working in reciprocating mode rotates to order about at the convex-concave axle by enduring plate.Since have emboss pit on the convex-concave axle, thus work as the groove position and very do the time spent between the plate, right very plate work, the drive tappet is flexible to make the operation of oil pump oil spout, makes diesel engine carry out the oil-feed of stand oil amount, decide power stage according to the fuel oil amount of providing of oil pump.According to the requirement of power stage, changing the adjusting oil inlet quantity is to realize that by the appointment operation of oil pump of three oil pumps namely three oil pumps can only an operation of oil pump.Regulate handle by pulling and realize and set operation of oil pump, when pull handle during to certain position, the position by positioning wheel changes the gap portions that makes the convex-concave axle and corresponding very plate is corresponding, and makes the with it operation of oil pump of correspondence, realizes quantitative oil spout.Can slide at the axle of regulating positioning wheel owing to be provided with the positioning wheel of locating slot, so pull handle can change very plate and oil pump that convex-concave axle notch alignment sets, realize the gearshift of oil pump.
According to the application of diesel engine and the needs of power stage, three set oil pumps are set respectively corresponding oil inlet quantity parameter, by pull handle, change the position of the corresponding very plate of convex-concave axle breach and oil pump, then can change the oil inlet quantity of diesel engine, thereby change the output power of diesel engine.
For example, for common peasant household, buy one 14.7 kilowatts diesel engine, when being used for drawing water, by pull handle, make 14.7 kilowatts of oil feed pump work, 14.7 kilowatts output power is provided; When the needs comminuting matter, need 11 kilowatts of output powers, then make it operation of oil pump with 11 kilowatts of oil inlet quantities by pull handle, export 11 kilowatts power; When needs farmland or sprayer spraying fruit tree medicine, then need 4.3 kilowatts power power, then pull handle is regulated the position of convex-concave axle breach and tappet, make 4.3 kilowatts of fuel feeding operation of oil pumps, in diesel engine, supply 4.3 kilowatts of corresponding fuel deliveries, thereby export 4.3 kilowatts of power, for the spray medicine.
Draw data through actual tests contrast and show, use the diesel engine of three oil pumps of the present invention can be than comparing fuel-economizing more than 30% by the diesel engine of throttle adjustment output power.And one the family namely can satisfy need of production with a diesel engine, saved investment.Therefore diesel engine of the present invention has obvious fuel-economizing, reduces carbon emission, saves economic input, convenient advantage and the beneficial effect that uses.
