为满足驾驶舒适性要求,出厂的大部分装载机均配装有空调制冷系统。部分客户为了降低采购成本,在采购装载机后请他人或自行加装空调制冷系统。本文以龙工LG853B型装载机加装空调制冷系统为例,介绍加装空调制冷系统的要求、关键部件的选配与安装要点,以及控制电路的设计方案。1.加装空调系统的要求装载机工作时具有作业环境恶劣、隔热密封差、行驶速度慢等特点,为此加装的空调制冷系统应满足以下4点要求:一是抗振性强。应根据
To meet the driving comfort requirements, most of the factory loaders are equipped with air conditioning and refrigeration systems. Some customers in order to reduce procurement costs, in the procurement of loaders, please or others to install air conditioning and refrigeration systems. In this paper, LUNGGANG LG853B loader air conditioning and refrigeration system as an example to introduce the requirements of the installation of air conditioning and refrigeration systems, the key components of the matching and installation points, as well as control circuit design. 1. Installation of air conditioning system requirements Loader working with harsh operating conditions, poor heat sealing, slow driving and other characteristics, for which the installation of air conditioning and refrigeration systems should meet the following four requirements: First, strong anti-vibration. Should be based on
