Determine the number of high-pressure pumps and the redundancy rate

Author:


For a normally operating high-pressure pump, generally only one is used, because one large high-pressure pump is equivalent to two small high-pressure pumps working in parallel (referring to the same head and flow rate). The large high-pressure pump has higher efficiency than the small high-pressure pump, so from an energy-saving perspective, it is better to choose one large high-pressure pump instead of two small high-pressure pumps. However, in the following situations, two high-pressure pumps can be considered for parallel operation:
