Abstract
The utility model discloses a single-cylinder vertical water cooling diesel engine, which comprises a machine body in which a crankshaft and a piston are arranged. A cooling water chamber in the machine body is communicated with a water condensator to form a circulating system of cooling water. The crankshaft or a part fixedly connected with the crankshaft is provided with a fan. A flow guide cover of a fan is arranged at a position facing an air inlet of the water condensator outside the fan, and cooling air is conveyed by the rotating fan through the flow guide cover to the water condensator for exchanging heat. The problem that an existing single-cylinder vertical cooling diesel engine is large in weight and requires frequent water filling is resolved.
Description
Technical field
The utility model relates to engine art, the vertical water-cooled diesel engine of especially a kind of small-sized single cylinder.
Background technique
Along with the raising of mechanization degree, the especially generally use of the miniature farm machinery in rural area, the vertical water-cooled diesel engine of small-sized single cylinder is as the power of small farm tiller, and its demand is increased day by day.And users require miniature farm machinery light and safe and reliable, and are lasting durable, thereby its main supporting vertical water-cooled diesel engine of small-sized single cylinder has just been proposed higher requirement; And the vertical water-cooled diesel engine of small-sized single cylinder that uses at present, if any the vertical water-cooled diesel engine of a 4.41 kilowatts single cylinder, for restricted volume and weight; Water tank is done lessly relatively, but because installation of water is less, and the vertical water-cooled diesel engine cooling water of this type of single cylinder does not circulate; Directly in cylinder body, seethe with excitement; Take away heat by evaporation of water, because of the continuous evaporation of water need frequently add water, unusual trouble; If will increase the water yield solves the volume that the problem that frequently adds water then must add large water tank, the weight of complete machine is increased; The present weight of this kind of single-cylinder water cooled diesel engine of 4.41 kilowatts is greater than 70 kilograms, and quality is relatively large, and solving the problem that frequently adds water by the volume that adds large water tank is a kind of unfavorable method.
The model utility content
The utility model problem to be solved provides the vertical water-cooled diesel engine of a kind of single cylinder, it can solve the existing vertical water-cooled diesel engine quality of single cylinder big with the problem that need frequently add water.
In order to address the above problem; The technological scheme of the utility model is: the fuselage of dress bent axle and piston in the vertical water-cooled diesel engine of this single cylinder includes; The water outlet of the cooling water chamber in the said fuselage is connected with a water condenser water intake, and the water intake of said cooling water chamber is connected with said water condenser water outlet; Said bent axle or with parts that this bent axle is fixedly connected on fan is housed, outside said fan, on the position of the intake grill of said water condenser, fan dome is housed; Through the fan that rotates cooling air is delivered to described water condenser and carries out heat exchange; And with the water cooling in the water condenser, the cylinder to high temperature in circulation of the water in the water condenser cools off.
The utility model is compared with the vertical water-cooled diesel engine of existing single cylinder has following effect:
Capable of circulation and through the water cooler heat exchange because of the cooling water of diesel engine cooling cylinder body, water can not explosive evaporation, and the fan on the diesel engine is delivered to water condenser with cooling air when work simultaneously, takes away the heat on the water condenser; So cooling water amount is little and need not frequently add water; Alleviate the weight of diesel engine simultaneously; About 75 kilograms of the existing common vertical water-cooled diesel engine weight of 4.41 kilowatts single cylinder, and the utility model, the vertical water-cooled diesel engine weight of 6.6 kilowatts single cylinder has only about 50 kilograms.
The utility model is compared with the vertical air-cooled diesel engine of existing single cylinder has following effect:
The cylinder cooling water of this cold diesel engine can realize that through the condenser cooling circulating water mode cools off, and soaks coldly with adopting, and relies on the existing single-cylinder water cooled diesel engine of cooling water boiling cooling to compare, and can reduce the consumption of cooling water, thereby alleviate the service weight of machine; On the other hand, this circulating water mode does not need the cooling water of frequently annotating, and is convenient under the environment of lack of water, work long hours; Again on the one hand, owing to can use special-purpose cooling liquid cooling, compare with constantly the annotate situation of cooling water of needs; Can reduce even keep the inner non-scaling of cooling system; Or fouling is very little, to keep the cooling performance of machine, improves the stability of machine run performance.In addition, the cooling of this circuit also than soak the boiling cooling have cooling more evenly rationally, tool is reliable, characteristics that can be not overheated can guarantee that machine works long-term and stably and can not reduce output power.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is to the vertical water-cooled diesel engine of single cylinder shown in Figure 3; Cylinder part in the fuselage 1 and crankcase are that integral body is cast; Cylinder liner 8 is inserted in the cylinder part in the fuselage 1; Cylinder head 5 and valve mechanism cover 4 are equipped with in cylinder liner 8 tops, the bent axle 13 in cylinder liner 8 inside connecting rods 9 are connecting piston 7 and crankcase; On one end of bent axle 13 flywheel 11 is housed, is set with fan 10 on the flywheel 11; The air guide sleeve 12 of fan 10 is housed on the position of the intake grill of water condenser 2 outside fan 10; Bent axle 13 drives fan 10 and rotates when rotating; The air communication that fan 10 drives is crossed air guide sleeve 12 and is blowed to water condenser 2; Make cooling water and machine outer air in the water condenser 2 carry out heat exchange, take away the heat on water condenser 2 surfaces; Water condenser 2 and fuel tank 6 are contained in the both sides of fuselage 1 respectively; The water outlet on cooling water chamber top is connected through the water intake of water pipe 3 with water condenser 2 tops around fuselage 1 inside cylinder; The water outlet of water condenser 2 water outlet bottoms is communicated with the lower water inlet of fuselage 1 cooling water chamber, makes the water condenser 2 formation cooling water recirculation system that is connected with water cavity in the fuselage 1.When the vertical water-cooled diesel engine of this single cylinder is worked, rely on the thermoconvection of the cooling water in the cooling water recirculation system itself to form circulating water flow.
