Abstract
The utility model provides a forced cooling water circulation system of vertical type single cylinder diesel engine, comprising a water pump, a radiator, a transmission shaft, a drive gear and a transition gear; wherein the water pump is arranged on the gear chamber cover of the diesel engine; the drive gear and the transition gear are respectively disposed at two ends of the transmission shaft; the drive gear is engaged with the crankshaft gear of the diesel engine. The utility model is characterized in that the transition gear is engaged with a carrier gear of the water pump, which transmits the power of the diesel engine to a feed pump to drive the water pump to work; the water inlet of the water pump is communicated with the water outlet of the radiator; the water outlet of the water pump is communicated with the water inlet of the water jacket of the diesel engine; the water inlet of the radiator is communicated with the water outlet of the water jacket of the diesel engine. The utility model is advantageous in that the structure is reasonable, the maintenance is convenient, the cooling is even and the effect is obvious; the working temperature of the diesel engine can be effectively controlled and the diesel engine can be prevented from being over-heated; the power, economical efficiency, reliability and durability of the diesel engine can be bettered.
Description
Technical field
The utility model relates to a kind of water cooling system of diesel engine, particularly a kind of vertical type single-cylinder diesel engine forced cooling water circulatory system.
Background technique
Diesel engine expands after component are heated because the structural feature of its body can produce the heating phenomenon in the course of the work, influences the normal matching gap between the component; The piston of at high temperature working, cylinder head, cylinder body, valve rigidity, intensity under strong heating condition all can significantly descend, so that deform and damage; High temperature also can cause lubricating condition to degenerate, the wearing and tearing between the aggravation component.At present, the water cooling system of vertical type single-cylinder diesel engine is generally natural recirculating type, utilizes the proportion difference of high and low warm water, produces natural convection, realizes the cooling water circulation.This cooling water recirculation system existence circulation is slow, cooling effect is poor, and inhomogeneous cooling is even, insecure shortcoming of working.In recent years also have the cooling water recirculation system of positive drive type to come out, but structure is comparatively complicated, functional reliability is relatively poor, and safeguard, repair very not convenient.
The model utility content
For overcoming the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, functional reliability strong, be convenient to the vertical type single-cylinder diesel engine forced cooling water circulatory system of maintenance and repair.
The technological scheme that its technical problem that solves the utility model adopts is: comprise water pump, radiator, transmission shaft, driving gear and transition gear; Described water pump is installed on the gear chamber cover of diesel engine, driving gear and transition gear are loaded on the two ends of transmission shaft respectively, and driving gear is meshed with the crankshaft gear of diesel engine, and transition gear is meshed with the carrier gear of water pump, with the power transmission feed water pump of diesel engine, drive pump working; Pump intake and radiator outlet interlink, and the water jacket water intake of pump outlet and diesel engine interlinks, and the water jacket water outlet of water inlet of radiator and diesel engine interlinks.
Above-mentioned water pump is a Centrifugal water pump.
The beneficial effects of the utility model are: it is rational in infrastructure, and is easy to maintenance, and cooling is even, effect is remarkable, can control the operating temperature of diesel engine effectively, and it is overheated to prevent, thereby makes diesel engine obtain good power character, Economy, reliability, durability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that water pump, 1-1 are that pump intake, 1-2 are that pump outlet, 2 is that transition gear, 3 is that transmission shaft, 4 is that driving gear, 5 is that crankshaft gear, 6 is that carrier gear, 7 is that gear chamber cover, 8 is that radiator, 8-1 are that water inlet of radiator, 8-2 are radiator outlet.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The vertical type single-cylinder diesel engine forced cooling water circulatory system described in the utility model comprises water pump 1, radiator 8, transmission shaft 3, driving gear 4 and transition gear 2; Described water pump 1 is a Centrifugal water pump, is installed on the gear chamber cover 7 of diesel engine; Driving gear 4 and transition gear 2 are loaded on the two ends of transmission shaft 3 respectively, transmission shaft 3 by Bearing Installation in the bearing hole of the gear chamber cover 7 of diesel engine, driving gear 4 is meshed with the crankshaft gear 5 of diesel engine, and transition gear 2 is meshed with the carrier gear 6 of water pump 1; Pump intake 1-1 and radiator outlet 8-2 interlink, and the water jacket water intake of pump outlet 1-2 and diesel engine interlinks, and the water jacket water outlet of water inlet of radiator 8-1 and diesel engine interlinks.
During work, the power of diesel engine passes to driving gear 2 by crankshaft gear 5, thereby drive transmission shaft 3 and driving gear 2 rotate in the lump, and the carrier gear 6 that driving gear 2 drives water pumps 1 rotates, and makes water pump 1 move.Water pump 1 sucks cooling water in the radiator 8 from radiator outlet 8-2, pump intake 1-1, behind water pump 1 adherence pressure, be depressed into the water jacket water intake of diesel engine from pump outlet 1-2, the cooling water that has certain pressure flows to the low pressure place, water jacket water outlet through diesel engine flows out, and take away a large amount of heats, the cooling water that temperature rises is back to water inlet of radiator 8-1, enters in the radiator 8 and cools off.Water pump 1 constantly is pressed in the diesel engine from the cooling water that radiator outlet 8-2 extracts out through supercooling, realizes cool cycles.
Claims (2)
1. the vertical type single-cylinder diesel engine forced cooling water circulatory system is characterized in that: comprise water pump, radiator, transmission shaft, driving gear and transition gear; Described water pump is installed on the gear chamber cover of diesel engine, driving gear and transition gear are loaded on the two ends of transmission shaft respectively, and driving gear is meshed with the crankshaft gear of diesel engine, and transition gear is meshed with the carrier gear of water pump, with the power transmission feed water pump of diesel engine, drive pump working; Pump intake and radiator outlet interlink, and the water jacket water intake of pump outlet and diesel engine interlinks, and the water jacket water outlet of water inlet of radiator and diesel engine interlinks.
