MOVING THE WATER PUMP WITH AN INTERNAL COMBUSTION ENGINE
Internal combustion engines can be divided into gasoline and diesel. As a result of the reaction of the fuel they use with oxygen, a mechanical energy emerges. We can use this energy in various places. They work in 2 and 4 strokes. Working principles are intake, compression, combustion and exhaust stroke. When these times are completed, it will have performed 1 cycle.
In gasoline engines, fuel mixed with air enters the combustion chamber. Combustion takes place by igniting the air-fuel mixture, which is compressed at the time of combustion, with a spark plug. On the other hand, in diesel engines, fuel is sprayed onto the compressed air under high pressure and temperature and combustion takes place. As a result, mechanical energy is generated in the motor.
The water pump is a separate section from the engine. As a result of this rotation, a pressure is created at the inlet of the impeller, and the hydraulic pressure created transfers water from one point to another.
Motorized water pump, namely motopumps, is a device used to transport liquids from one place to another by using mechanical energy. The working principle of the water pump is the operation of the pump by converting the mechanical energy obtained from the internal combustion engine into hydraulic energy. In other words, when the pump is driven by an internal combustion engine, the operating point of the pump must be within the continuous operating range of the internal combustion engine. In this way, our water pump can work.
The advantages of internal combustion engine water pumps are that we can easily operate them in areas where there is no power cut or electricity. It has high flow and Hmax values. Although horsepower is generally considered in the selection of a motorized water pump, Hmax and flow values are the most important factors. There are water pumps with very different capacities at the same horsepower. Therefore, when choosing a water pump, attention should be paid to the diameters of the suction and discharge lines, the flow rate, the pressure value, and even the friction losses in the pipes if the water pump system will be newly installed. In the selection of the water pump, the flow and pressure information as well as the pipe through which this flow will pass should be carefully calculated. For example, passing a flow of 150 m3/hour through a 2” pipe will cause a lot of friction loss.
