(2) Fault handling: Close the pump unit test valve; Adjust the phase sequence of the incoming power supply; Replace the high-pressure pump; Working within the rated value of the pump set.

3、川消泵组不启动

3. Chuanxiao pump group does not start

（1）故障原因分析：高压泵接触器未闭合；泵组停止触点断开；LOGO！未执行程序；电源未接通；断水水位保护。

(1) Fault cause analysis: The high-pressure pump contactor is not closed; The pump unit stop contact is disconnected; LOGO! Not executing the program; The power supply is not connected; Water cut-off level protection.

（2）故障处理：闭合接触器；闭合泵组停止触点；检修LOGO！必要时更换；接通电源；恢复调节水箱水位。

(2) Fault handling: Close the contactor; Close the pump unit stop contact; Repair the logo! Replace if necessary; Connect the power supply; Restore the water level of the regulating water tank.

4、稳压泵频繁启动

4. Frequent start-up of pressure stabilizing pump

（1）故障原因分析：管道有渗漏；泄压阀密封不好；测试阀未关紧；单向阀密封垫上粘连杂质。

(1) Fault cause analysis: There is leakage in the pipeline; Poor sealing of safety relief valve; The test valve is not tightly closed; Adhesive impurities on the sealing gasket of the one-way valve.

（2）故障处理：管道渗漏点补漏；检修泄压阀；完全关闭测试阀；清洗单向阀并清洁水箱及管道。

(2) Fault handling: repairing pipeline leakage points; Maintain the safety relief valve; Fully close the test valve; Clean the one-way valve and clean the water tank and pipelines.

5、稳压泵规定时间内不能恢复压力

5. The regulated pump cannot restore pressure within the specified time

（1）故障原因分析：管道内残存空气；管道有渗漏；高压球阀渗漏；稳压泵出口压力低；稳压泵损坏。

(1) Fault cause analysis: residual air in the pipeline; There is leakage in the pipeline; Leakage of high-pressure ball valve; Low outlet pressure of the pressure stabilizing pump; The pressure stabilizing pump is damaged.

（2）故障处理：完全排除管道空气；管道渗漏点补漏；见下文高压球阀渗漏故障处理方法；调节稳压泵压力调节螺丝；更换稳压泵。

(2) Fault handling: completely eliminate the air in the pipeline; Pipeline leakage point repair; Refer to the following methods for handling leakage faults of high-pressure ball valves; Adjust the pressure regulating screw of the stabilizing pump; Replace the pressure stabilizing pump.
