How big a generator does a 90kW Roots blower need?

100 kW. The 90 kW Roots blower needs at least a 100 kW generator to work together to ensure the efficient operation of the power generation system, so the 90 kW Roots blower needs a 100 kW generator. Roots blower is a positive displacement fan, with impeller end faces, front and rear end covers of the fan. Its principle is a rotary compressor that compresses and transports gas by using two blade rotors to make relative movement in the cylinder.

To determine how large a generator is needed for a 90 kW Roots blower, the following factors need to be considered:

1. Motor power for driving Roots blower: The motor power required for driving Roots blower is 90 kW, so the power of the selected generator should be at least greater than or equal to 90 kW.
2. Generator efficiency: different types and generators have different efficiency. Generally speaking, generators with high efficiency are more economical than generators with low efficiency. Therefore, selecting generators with high efficiency can save energy and reduce costs.
3. Load capacity: In addition to meeting the motor power required to drive Roots blower, it is also necessary to consider the impact of other load factors, such as the power demand of other additional equipment, transmission devices, and the demand for standby power.
To sum up, for the 90 kW Roots blower, we can choose a generator with a power greater than or equal to 90 kW, and determine the generator model and model specification according to the actual situation.
