本文通过试验和对有关资料的分析研究,提出了油水温度对柴油机械损失功率和额定功率影响的四个计算公式,提出了最高爆炸压力对倒拖机械损失功率影响的修正公式。实验和计算数据表明,误差均小于5％,有较好的通用性。同时对不发火缸检爆阀打开或关闭对机械损失功率影响的变化规律,作了详细的分析研究,使上述问题由定性走向定量,对正确使用管理柴油机有一定指导作用。
Based on the test and analysis of related data, this paper puts forward four formulas for calculating the influence of oil-water temperature on the power loss and rated power of diesel machinery, and proposes the correction formula of the influence of the highest explosion pressure on the power loss of the inverted mechanical. Experimental and calculation data show that the errors are less than 5%, and has good generality. At the same time, it does a detailed analysis and research on the variation of the influence of the open and close of the explosion-proof valve on the loss of mechanical power, which makes the above-mentioned problems go from qualitative to quantitative and has certain guidance to the proper use of the diesel engine.
