Don't save money. The price of a pound of diesel is 7.62 yuan to 7.59 yuan, while the price of a kilowatt hour of electricity is 0.52 yuan to 0.62 yuan. It is better to use an engine with a water pump to pump water rather than using a diesel engine to generate electricity. The essential principle of a diesel generator is to convert the chemical energy of the engine fuel into rotating mechanical energy, and the generator converts the mechanical energy into electrical energy.
What size generator is needed for a sewage pump with a diameter of 100 mm?
A water pump of approximately 3 kW.
When a generator is fitted with equipment, it is usually necessary to consider the power factor and properties of the equipment, such as resistance, inductance and capacitance. Inductive loads require smaller equipment. and the location of the motor must alsonot be taken into account. It will be overloaded during operation. The motor itself has a certain overload capacity, the motor will not be burned but the generator will therefore be damaged. Engine power must be taken into consideration. The general overload capacity of the motor is λ=1.8~2.2. In this way, the water pump supplied by the generator is: 6.5kw/2.2=3kw.
10 to 15KW. According to a query on the Industrial Network, a sewage pump with a diameter of 100 mm requires a generator with a power of 10 to 15 kW. When choosing a generator, you should pay attention to the fact that the power of the generator must match the power of the sewage pump. The power of the sewage pump is larger, but the power of the generator is too low, which will drive the generator. overload and damage the generator.
