某线设计的内燃机务段大多已交付运营,现将运营后所了解到的一些问题,提出几点粗浅看法。由于深入调查研究不够,不妥之处,请指正。一、油罐的加热保溫问题 1966年设计时,根据当时部的指示,按使用0号柴油设计。由于这个地区最低温度在-40°～-50℃,因此,在油库设计中,参照某部设计院图纸,在罐内距底0.5米处设几组加热排管。经运营实践,证明这种加热方式是有缺点的,加热管发生漏泄,无法修补或拆除,现场建议改在罐外,目前有的段已改在罐外。
Most of the internal combustion engines designed for a certain line have already been delivered to operation. Some of the problems learned after the operation are now put forward, and some superficial opinions are put forward. Due to in-depth investigation and research is not enough, please correct me wrong. First, the tank heat insulation problem 1966 design, according to the then Ministry instructions, according to the use of 0 diesel design. As the lowest temperature in this area is -40 ° ~ -50 ℃, therefore, in the design of the oil depot, with reference to the drawings of a design institute, several sets of heating pipes shall be arranged within 0.5m from the bottom of the tank. The operation proved that this heating method is flawed, heating pipe leaks, can not be repaired or removed, the scene proposed to change the tank, some of the sections have been changed outside the tank.
