通过对本钢板材股份有限公司运输部在役机车温度控制系统的研究,提出利用温度变送器代替多个温度继电器来完成内燃机车温度的控制。消除了温度继电器易损耗、维修费用高的缺陷,提高了内燃机车的温度控制技术。 Through the research on the locomotive temperature control system in service of the transportation department of Bengang Steel Plates Co., Ltd., it is proposed to use the temperature transmitter instead of a plurality of temperature relays to complete the temperature control of the locomotive. Elimination of the temperature relay easy to wear and tear, high maintenance costs defects, improve the temperature control of diesel locomotive technology.
