用一种发动机的监测装置对装有变矩器和液压泵的铲运机进行了现场试验。试验表明,由于辅助设备和传动装置的附加能耗,可得的最大有效功率可能达不到全速时的峰值。单纯地降低发动机转速,可以节省15～25％的燃料消耗,有效功率的损失却不大。而某些设备,为了降低转速,需要改进变矩器。必要时所作的此项改进,其费用可从排气、要求通风量、燃料消耗、辐射热、噪音和液压系统维修等的减少以及回转部件和过滤器寿命的延长,设备利用率的提高等方面得到补偿。
A scraper equipped with torque converter and hydraulic pump was field tested with an engine monitoring device. Experiments have shown that due to the additional energy consumption of auxiliary equipment and transmission, the maximum available power may not reach peak at full speed. Simply reduce the engine speed, you can save 15 to 25% of fuel consumption, the effective power loss is not large. Some devices, in order to reduce the speed, need to improve the torque converter. Such improvements, if necessary, may be made in terms of exhaust gas, required ventilation, fuel consumption, radiant heat, reduction of noise and hydraulic system maintenance, as well as longer lifespan of rotating components and filters, increased equipment availability, etc. Get compensated.
