The invention discloses foam generating testing equipment allowing the foam quality to be adjusted. The foam generating testing equipment comprises a compound stirrer, a first liquid storage pot, a second liquid storage pot, a proportional mixer and a foam generator. The compound stirrer is used for dissolving raw materials for preparing foams into water and uniformly mixing the raw materials and the water to prepare a stock solution, the stock solution is conveyed to the first liquid storage pot through a pipeline under the effect of compressed gas in the compound stirrer, and conveyed to the proportional mixer through a pipeline under the effect of compressed gas in the first liquid storage pot, meanwhile, the water in the second liquid storage pot is conveyed to the proportional mixer through a pipeline under the effect of the compressed gas, the proportional mixer mixes the stock solution conveyed by the first liquid storage pot and the water conveyed by the second liquid storage pot uniformly according to the proportion and then conveys the mixture into the foam generator, the mixture is mixed with compressed air in the foam generator uniformly to generate the foams, and finally the foams are discharged through a foam outlet of the foam generator. The foam quality can be adjusted, the foaming rate is effectively controlled, and the stock solution is prevented from being wasted.
