A typical high pressure water thermal descaling system and its working principle are intro- duced. The reciprocating plunger pump unit is core equipment in the system, and the unit comprehen- sive performance is studied. A comprehensive evaluation index system is built based on three aspects of the unit such as energy saving, reliability and safety to evaluate the performance of the unit. Base on analytic hierarchy process （AHP） and fuzzy method, a weight analysis approach for the factors in the performance comprehensive evaluation index system is established. Then the fuzzy membership degrees of the measured evaluation factors are investigated. On this basis, a mathematical model of comprehen- sive performance evaluation is proposed based on AHP and fuzzy method, and an evaluation method for comprehensive performance is developed. By using an example, the weights of the factors in the eva- luation index system for the reciprocating plunger pump unit in a high pressure water descaling system are analyzed, and the measured evaluation factors fuzzy membership degrees are calculated. The re-suhs of comprehensive performance are also analyzed and the feasibility of this evaluation method is validated.
