What should I do if the air conditioning system of Komatsu loader fails? The uncooled air conditioner of the loader is one of the common faults of the air conditioner. As a common construction machinery, the loader has its special working conditions and customer groups. The steadily increasing infrastructure construction at home and abroad requires a large number of loaders. The working environment is harsh, with high temperatures and dust, and the daytime temperature of some construction sites often exceeds 40 degrees. If the air conditioner is not refrigerated, you need to carefully check all links, and if necessary, ask professional maintenance personnel. 1 Principle of Loader Air Conditioning First of all, it is necessary to introduce the basic principles of air conditioners. Similar to car air conditioners, loader air conditioners also use refrigerant materials to absorb or release heat during the conversion process between gaseous and liquid to adjust the environmental parameters in the cab to make the occupants feel comfortable. Ensure occupants' health and operation and driving safety. The specific functions of the air conditioner are as follows: (1) Adjust the temperature of the air in the car, cool down in summer, heat in winter, defrost and remove fog, and ensure visibility and driving safety; (2) Purify the air in the car and adjust the humidity of the air in the car to meet the needs of the human body; (3) Adjust the flow rate of the air in the car. If the flow rate is too high or too low, the body will feel uncomfortable. Loader air conditioning devices are mainly composed of: compressors, condensers, liquid storage bottles, expansion valves, evaporators (usually evaporators include: evaporating cores, heating cores), blowers, refrigerants, connecting pipes, tensioning devices , Belt and other components. When the air in the car flows through the evaporator, the liquid refrigerant in the evaporator absorbs heat from the air and evaporates into a gaseous state. The gaseous refrigerant enters the compressor, is compressed, flows through the condenser, and becomes liquid after dissipating heat. Air conditioning is not cooling solution steps: Almost all loaders air conditioning failure will eventually cause the operator to feel that the air conditioning is not cooling, such failures have many potential causes. Each link in the system needs to be inspected from a professional perspective, and the solutions will be different. The fault diagnosis method of loader air conditioner is usually through watching (observing the surface of the equipment of the system), listening (listening to the sound of the machine running), touching (touching the temperature of each part of the equipment with your hand), measuring (using a thermometer, pressure gauge, multimeter, inspection Leakage test related parameters) and other means. At the same time, you should carefully ask the driver about the fault and determine whether it is improper operation or the fault caused by the equipment itself. If it belongs to the former, the correct operation method should be introduced to the driver in detail; if it belongs to the latter, it should be carried out according to the above four aspects. Comprehensive analysis, find out the cause of the failure, and then repair.
