The utility model is characterized in that the blade wheel of the micro water pump is directly connected with the driving crank of the petrol engine; the pump body is fixed with the petrol engine body through screws; the petrol engine is provided with the cooling water circulation system; the utility model has the advantages of high efficiency, low energy consumption, light weight, easy fabrication, low cost, and convenient operation; as the petrol engine water pump has small size, the petrol engine water pump is particularly suitable for the field irrigation of a region without power or during the power failure time, and the utility model can also be used for the water supplying of a miniature factory and a family.
Description
The utility model is a kind of minitype gasoline machine water pump.It is to be power with the put-put, is the combined type water lifting machinery of suction engine with miniature Centrifugal water pump.
The micro pump of domestic production at present mainly is based on the micromachine water pump, and the shortcoming of its maximum is not to be suitable for the area of not having electricity, simultaneously owing to be subjected to the restriction of power supply, the place to use can not choose at random, makes troubles, and existing petrol engine water pump, because unit volume is big, complex structure, the cost height, weight is big, efficient is low, and energy waste is bigger.In CN87216017, announced a kind of Efficient water pump, its purpose is to have designed the efficient anti-dress motor and water pump of dress in integral structure and the shell, the impeller of water pump directly links to each other with the rotor of motor, during work, the directly cooled machine but water flows in frame, its deficiency is to be provided with and can not to choose at random in areas without electricity use or place to use, and makes comparatively complicated.
At above-mentioned existing problem, to be that design is a kind of can use the minitype gasoline machine water pump that combines with put-put and miniature Centrifugal water pump at areas without electricity to the purpose of this utility model, for cutting down the consumption of energy, raise the efficiency, on the type of cooling of petrol engine, designed circulating water cooling system to replace air-cooled equipment.
The purpose of this utility model is achieved in that a kind of petrol engine water pump of being made up of petrol engine, cooling water recirculation system and miniature Centrifugal water pump of design.On the compound mode of petrol engine and water pump, adopt water pump vane and petrol engine driving crank directly to link, nut is fastening, coaxial running, simultaneously, design one tapered hub between the water seal of bent axle and pump, this axle sleeve and bent axle run-in synchronism can guarantee that the water seal seal clearance is little in the pump, and the axle wearing and tearing are few.The petrol engine body works to support petrol engine and micro pump is installed; Pump seat directly is connected on the body by screw, and pump case is fastened on the pump seat.
Cooling water recirculation system of the present utility model comprises the step that blocks water, pump case, cooling water tank, water outlet ozzle and conduit, water inlet ozzle and conduit, petrol engine cylinder cylinder cap.Wherein a kind of design proposal is that the petrol engine cylinder head is replaced by a kind of cooling water tank.This cooling water tank had both played the effect of petrol engine cylinder head, play the effect of cooling petrol engine again, its working principle is to utilize in the micro pump spiral case and the pressure reduction of pump drainage mouth, circulating water is drawn from the cooling water tank water inlet ozzle on the pump case, enter cistern circulated water road circulation by penstock, enter the water that pump drain pipe and waste pipe extract out again through the cooling water tank outlet pipe and together discharge.In design, for guaranteeing that water can successfully enter circulating water and draw pipeline, on the snail road of pump case, designed the step that blocks water, 0.2-5cm place before the cooling water tank water inlet ozzle on pump case snail road, its position.The effect of step of blocking water is to cause a slight eddy current, makes water successfully enter circulating pipe and enters in the water pipe.
The utility model has following advantage compared with the prior art: (1) is in light weight, and is easy to use, and field irrigation, midget plant and family when being specially adapted to areas without electricity or power failure supply water; (2) composite structure of employing miniature gasoline engine (as the motor vehicular engine) and micro pump reduces manufacture cost, and is easy for installation; (3) because petrol engine adopts cooling water recirculation system, petrol engine efficient is improved greatly, reduced energy consumption simultaneously; (4) cooling water tank enters the design and installation of pipe, has both played the cooling water ringing, has the effect of micro pump exhaust port again concurrently.(5) adopt neoteric motor auto electronic fire maker, ignition system is simplified, starting is fast, reliable.
