Introduction to electric passenger train air conditioning unit frame

Introduction to electric passenger train air conditioning unit 2019 - rack 02 - 28 kunming metro line 1/2 electric passenger train air conditioning unit adopts KG29N type air conditioning unit, air conditioning unit state main quality directly affect the operation of the electric passenger train the air quality inside the passenger compartment, in the process of aircraft repair, air conditioning unit will be removed out of the car for high level maintenance. Air conditioning unit frame repairing maintenance unit mainly to remove out of the car to deep clean. Due to the dust inside the tunnel is more and more humid air, air conditioning unit interior also are more likely to stick dust, dust is very thick, passengers in order to ensure that the process of operation to create a comfortable environment, aircraft repair of vehicle air conditioning unit when the internal parts appearance, fresh air filter and return air grille, light air way deep cleansing, to return air mouth, air diffuser, air supply grille, clean check electrical components. Silence of the air conditioning unit, is full of dust in the air, water cannon after cleaning, also need to clean up the corner by hand. In the process of daily maintenance, axial flow fan, centrifugal fan, motor bearings are designed for maintenance free, but when the aircraft repair need for air conditioning unit axial flow fan, centrifugal fan and motor bearing replacement, measuring the motor parameters, replace the mixed air filter, return air mouth sealing strip. In addition, the working process of the centrifugal force in the form of a bearing to the machinery and, based on the cause of vibration and the noise, accelerate the bearing wear, shorten the mechanical life, serious when can cause destructive accidents, therefore, in the process of the aircraft repair must balance test was carried out on the blades, to allow the balance precision grade, make the mechanical vibration amplitude adjustment in the permitted range.
