工程机械、重卡、农机、汽车配件常用小常识 (Common Knowledge about Construction Machinery, Heavy Truck, Agricultural Machinery, and Auto Parts)

1. 工程机械多久需要更换液压油？ (How often should hydraulic oil be changed in construction machinery?)

   液压油的更换周期取决于设备的使用工况和液压油的品质。一般来说，建议每2000-4000小时更换一次液压油。恶劣工况下应缩短更换周期。 (Hydraulic oil replacement cycle depends on the equipment's operating conditions and oil quality. Generally, it is recommended to replace hydraulic oil every 2000-4000 hours. Shorten the replacement cycle under harsh conditions.)

2. 重卡轮胎气压多少合适？ (What is the appropriate tire pressure for heavy trucks?)

   重卡轮胎气压应根据轮胎型号、载重情况和行驶路况进行调整。一般而言，前轮气压为8-9bar，后轮气压为7-8bar。请参考车辆使用手册或轮胎制造商的建议。 (Heavy truck tire pressure should be adjusted according to tire model, load conditions, and road conditions. Generally, the front tire pressure is 8-9 bar, and the rear tire pressure is 7-8 bar. Please refer to the vehicle manual or tire manufacturer's recommendations.)

3. 农机柴油滤清器多久更换一次？ (How often should diesel filters be replaced in agricultural machinery?)

   农机柴油滤清器的更换周期也受使用环境影响。建议每500小时或每年更换一次，以保证燃油系统的清洁，避免发动机故障。 (Agricultural machinery diesel filter replacement cycle is also affected by the operating environment. It is recommended to replace it every 500 hours or annually to ensure the cleanliness of the fuel system and avoid engine failures.)

故障案例与解决方案 (Fault Case and Solution) - 文字颜色与背景颜色形成对比色

故障现象 (Fault Phenomenon): 挖掘机液压系统动作缓慢无力 (Excavator hydraulic system operates slowly and weakly)。
