Description

Heating system for emergency diesel engine overhaul Technical Field The utility model relates to the technical field of emergency diesel engine overhaul, in particular to a heating system for emergency diesel engine overhaul. Background In order to ensure the safe production of a power plant, the emergency diesel engine must be in a standby state at any time, and the daily maintenance and the maintenance of the emergency diesel engine are important in order to maintain the good working condition of the emergency diesel engine. The discharge, discharge and temperature of lubricating oil and cooling water are important factors affecting the maintenance quality and maintenance efficiency of the emergency diesel engine. The discharge speed of the lubricating oil is too high, so that the risk of blockage is easily caused by insufficient lubrication or impurity brought out of certain parts of the machine, and the maintenance efficiency is affected and the problem of old oil residue is caused by low discharge speed. Too high a temperature in the use of lubricating oil may deteriorate the lubricating property and accelerate oxidation, and too low a temperature may deteriorate the fluidity and may cause insufficient lubrication and may be difficult to start. The rapid discharge of cooling water risks thermal shock of the components and may cause air to enter the cooling system to affect heat dissipation efficiency, and the slow discharge may reduce maintenance efficiency and cause impurity residue risk. The cooling water temperature affects the heat exchange efficiency and the heat dissipation capacity of the engine. Therefore, in order to improve the maintenance quality and the maintenance efficiency of the emergency diesel engine, it is necessary to design a device for controlling the discharge, the discharge and the temperature of the lubricating oil and the cooling water.
