故障现象：开机后机器没有净化液输出。机器面板上压力表的系统压力指示为零。流量计没有流量输出指示。机器内部管路系统畅通，也无泄漏现象。电气控制系统各部分工作完全正常。分析检修：根据上述现象分析可得，机器没有输出的主要原因可能是增压泵工作不正常，导致管路系统 Symptom: After the machine is turned on, there is no cleaning fluid output. The system pressure indicator on the pressure gauge on the machine panel indicates zero. The flow meter does not have a flow output indication. The internal piping system of the machine is unblocked and there is no leakage. All parts of the electrical control system work completely normal. Analysis and maintenance: According to the analysis of the above phenomena, the main reason why the machine does not output may be that the booster pump is not working properly, resulting in pipeline system
