液压系统压力测试接口的重要性

Importance of Hydraulic System Pressure Test Ports

液压系统是推土机的“心脏”，其压力是否正常直接影响到整机的作业效率、燃油经济性和部件寿命。通过对系统各关键点的压力进行精确测量，可以快速诊断出潜在的泵、阀、油缸或管路问题，从而避免更严重的故障发生。了解并正确使用这些测试接口是每一位机械师和设备所有者必不可少的技能。

The hydraulic system is the "heart" of the dozer, and its pressure directly impacts the machine's operational efficiency, fuel economy, and component lifespan. By accurately measuring the pressure at key points in the system, one can quickly diagnose potential issues with pumps, valves, cylinders, or lines, thus preventing more serious failures. Knowing and correctly using these test ports is an essential skill for every mechanic and equipment owner.

如何进行压力测试（以通用流程为例）

How to Perform a Pressure Test (General Procedure)

1. 准备工作 (Preparation): 确保推土机停放在平坦地面上，发动机处于怠速状态，液压油温度达到工作温度。

2. 连接压力表 (Connect the Gauge): 找到相应的测试接口，使用合适的快速接头和压力表连接。确保连接牢固，避免漏油。

3. 进行测试 (Perform the Test):

• 空载测试： 测量主泵或多路阀的空载压力。

• 负载测试： 在对液压缸或马达施加负载时，测量其回路压力。例如，将铲刀提升到末端并保持，观察压力表的读数。

4. 记录与分析 (Record and Analyze): 将测得的压力值与小松官方服务手册中规定的标准值进行对比。如果读数超出正常范围，可能需要进一步检查相关部件，如溢流阀、主泵或油封。
