Description
Technical field
The utility model relates to a kind of engine cooling apparatus of water pump assembly.
Background technique
Water pump is the most frequently used a kind of agricultural tools.Generally the motor of the water pump that uses as agricultural machinery all is a fuel engine, because of fuel oil produces a large amount of heats engine temperature is risen significantly during fuel engine work, seriously influence the proper functioning of motor, therefore must cool off to guarantee the proper functioning of motor motor.
Fuel oil type engine cooling mode commonly used has air-cooled and water-cooled.Air-cooled, as to utilize air-flow that motor is cooled off exactly mode.Different modes according to air-flow produces can be divided into natural air cooled and forced air cooling.The forced air cooling utilization be mechanical air blast, generally be fan, fan needs consumption of engine power, and what need most cooling on the motor is positions such as firing chamber, outlet valve, spark plug, but since it seal, so air-flow can not be directly to its cooling.Thereby the blower cooled engine radiating effect is not satisfactory, causes engine operating duration generally can not surpass 3 hours continuously, and is easy to occur autostop, the phenomenon of scuffing of cylinder bore.
And the cooling water system that existing water-cooled engine is used all is to rely on manually to add water or water pump water adding, and the cooling water in the water tank raises because of the heat that absorbs motor makes water temperature, even the phenomenon of boiling is arranged.Water temperature raises, and just can not guarantee favorable cooling effect, makes rubber parts and water pipe aging, the cylinder cap distortion, and motor is operation at high temperature for a long time, head gasket may be punctured, and engine life reduces, and cylinder, scuffing of cylinder bore appear embracing in severe patient.When using the water pump water adding, water pump has increased the power consumpiton of motor, certainly will reduce the power of motor.Also have, if used hard water in water tank, will form incrustation scale in cooling system for a long time, cause the engine thermal exchange efficiency to reduce, above-mentioned phenomenon has all seriously influenced the effect of water-cooled, causes the water-cooled effect not satisfactory.
Moreover in order to make water tank stable under the vibration condition of motor, water tank all adopts casting, and becomes one with motor itself, so Heavy Weight is not easy to carry.
The model utility content
The utility model technical issues that need to address just are to overcome the existing not satisfactory defective of water pump assembly fuel engine cooling effect, a kind of engine cooling apparatus of water pump assembly is provided, its good heat dissipation effect, with with constant power type contrast efficiency height, and can work long hours continuously, can control the phenomenon that reduces the power of motor because of heat radiation well.Increase motor working life, and in light weight, be easy to carry.
For addressing the above problem, the utility model adopts following technological scheme:
The engine cooling apparatus of a kind of water pump assembly of the utility model, comprise frame, be installed in the fuel tank that the fuel engine in the frame is connected with fuel engine and reach the water pump that is connected with fuel engine, engine main body is set with a cylinder body water jacket outward, described cylinder body water jacket upper end and water tank are communicated with, described water tank is provided with intake pipe, cylinder body water jacket is provided with a waste pipe, and described water pump exhaust port is installed a water pipe, and described tank inlet pipe is connected with water pump exhaust port water pipe.
In order to control the water tank water intake amount, water pump exhaust port water pipe described in the utility model and exhaust port joint are equipped with a water control valve.
Draining for convenience, the terminal water outlet of cylinder body water jacket waste pipe described in the utility model is raised above water tank minimum level position, water tank minimum level height be positioned at the water tank height 2/3 on.
In order to keep water level balance and enough intake pressures, the position that tank inlet pipe described in the utility model enters water tank is higher than the terminal water outlet of described cylinder body water jacket waste pipe.Preferred scheme is that described tank inlet pipe inserts water tank from tank top.
In order to reduce installation volume, water tank described in the utility model and fuel tank are installed on the frame top side by side, are a kind of horizontal type structure.
In general, when water temperature was controlled at about 80 ℃, the service behaviour of motor reached best.Water temperature is controlled at 75-85 ℃ in the cylinder body water jacket described in the utility model.
Working principle of the present utility model is: be connected with water pump exhaust port water pipe by tank inlet pipe, the pressure that water pump produces when utilizing pump working is gone into water tank with hydraulic pressure, and controls the size of water tank water intake amount by the switch on the water pump relief opening water pipe.Thereby reach the effect of control water temperature.Because water tank and cylinder body are communicated with, and make water center on whole cylinder sleeve, by flowing of water, transmit the heat that cylinder body produces, after water comes out from the cylinder body water jacket drain opening, by discharging, to reach radiating effect with the water pipe of cistern water level balance.
The water that the utility model remains in the cylinder body water jacket is to press next flowing cold water from water pump, and the heat that cylinder body produces is discharged at any time, thereby reaches better heat radiating effect.When water temperature was controlled at about 80 ℃, the service behaviour of motor reached best.Water temperature is controlled at 75-85 ℃ in the cylinder body water jacket described in the utility model.And because the not additional equipment that needs consumption of power so reduced the power loss of motor, makes the power plant operating time lasting, working efficiency increases.
The utility model good heat dissipation effect and with constant power type contrast efficiency height, and can work long hours continuously, and the life-span is long.Can control the power loss that reduces because of heat radiation well.And in light weight, be easy to carry.
