Abnormal temperature is the main cause of air compressor failure accident, so how to reduce the system temperature and maintain an efficient cooling system is very important to prolong the life of air compressor. The cooling system of air compressor can be optimized from the following aspects.
By improving the ventilation conditions of the compressor room, the air compressor temperature is reduced. The working environment of mechanical equipment has great influence on the use of mechanical equipment. Reducing the temperature of the equipment can reduce the adverse effect on the equipment. With the increase of the service life of the unit, the calorific value of the unit is also increasing day by day, and the original way of air intake from the inlet duct to meet the gas production and cooling unit is no longer applicable. For example, Hangzhou cigarette Factory transforms the left and right side doors of the unit into a louver form of downwind, inhales the ambient temperature air from the lower part of the equipment, and then discharges it from the upper exhaust fan, which effectively reduces the unit temperature. The company's original unit cooling exhaust directly into the exhaust passage, and then discharged from the roof, but due to the unit exhaust fan power is small.
The air exchange rate in the channel is not high, which makes the temperature in the channel increase and affects the cooling of the unit. By installing an exhaust fan at the outlet of the exhaust passage, the air velocity in the passage is increased, and the number of air exchange in the passage is increased, thus the cooling effect of the unit is improved.
Avoid scaling of cooling system. The scaling of the cooling system is the main cause of the abnormal temperature of the air compressor, which makes the cooling water can not effectively heat transfer with the cylinder wall, resulting in the increase of the cylinder operating temperature and the accident. To solve this problem, many scholars at home and abroad have carried out a lot of research work and obtained some research results. The main methods to avoid scaling in the cooling system are to strengthen the monitoring and management of cooling water quality, to transform the cooling water and to clean the air compressor regularly. The cleaning and scale removal methods include mechanical scale removal and chemical scale removal.
