挖掘机作业工况恶劣,为了提高驾驶员在驾驶室作业的舒适度、提高作业效率、保障人身安全,大都安装了空调系统。本文介绍3例小松挖掘机空调系统常见故障排查过程。1.出风口出风不凉爽(1)原因分析1台某型挖掘机空调系统出现出风口出风不凉爽故障。空调系统制冷通过压缩机运转使制冷剂循环来实现的,而压缩机的运转是通过电磁离合器通电来实现的。因此我们分析,空调系统不制冷的原因有以下3个方面:一是缺少制冷剂,二是压缩机电磁离
Excavators work bad conditions, in order to improve driver comfort in the cab operation, improve work efficiency, protect personal safety, most installed air-conditioning system. This article describes 3 cases of Komatsu excavator air conditioning system troubleshooting process. 1. Outlet outlet is not cool (1) Analysis of a cause of an excavator air-conditioning system outlet outlet is not cool failure. Air-conditioning system refrigeration through the compressor to run the refrigerant cycle to achieve, while the compressor is running through the electromagnetic clutch energized to achieve. Therefore, we analyze the air conditioning system is not cooling the following three aspects: First, the lack of refrigerant, the second is the electromagnetic compressor
