本文从建立液压泵温度特性的擞学模型入手,进行实例计算,对液压泵的温度特性作了理论分析,并通过试验证明,对于没有安装自动恒温调整装置的液压系统,应用本文给出的理论公式,可以有效地控制系统的油温,使其不致温升过高而导致系统性能的劣化,因而在工程上有一定实际意义。 In this paper, starting from the establishment of a mathematical model of the temperature characteristics of the hydraulic pump, the calculation of a case is made and the temperature characteristics of the hydraulic pump are theoretically analyzed. It is proved through experiments that for the hydraulic system without the automatic thermostat adjusting device, Formula, can effectively control the oil temperature of the system, so that it does not cause excessive temperature rise and lead to the deterioration of system performance, and therefore has some practical significance in engineering.
