1、泵組連接處有滲漏
1. Leakage at the connection of the pump unit
（1）故障原因分析：連接件松動；連接處O 型圈或密封墊損壞,；連接件損壞,。
(1) Fault cause analysis: loose connectors; Damaged O-ring or sealing gasket at the connection; Damaged connectors.
（2）故障處理：擰緊連接件；更換O型圈或密封墊,；更換連接件,。
(2) Fault handling: Tighten the connectors; Replace the O-ring or sealing gasket; Replace the connector.
2、泵組出口壓力低
2. Low outlet pressure of pump unit
（1）故障原因分析：泵組測試閥未關(guān)閉,；泵組進線電源反相,；高壓泵損壞；使用流量超出額定值,。
(1) Fault cause analysis: The testing valve of the pump unit was not closed; The power supply of the pump unit inlet is in reverse phase; High pressure pump damaged; The usage flow exceeds the rated value.
（2）故障處理：關(guān)閉泵組測試閥,；調(diào)整進線電源相序；更換高壓泵,；在泵組額定值內(nèi)工作,。
(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. Chuanxiao pump group does not start
（1）故障原因分析：高壓泵接觸器未閉合,；泵組停止觸點斷開,；LOGO！未執(zhí)行程序,；電源未接通,；斷水水位保護。
(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）故障處理：閉合接觸器,；閉合泵組停止觸點,；檢修LOGO！必要時更換,；接通電源,；恢復調(diào)節(jié)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,、穩(wěn)壓泵頻繁啟動
4. Frequent start-up of pressure stabilizing pump
（1）故障原因分析：管道有滲漏,；泄壓閥密封不好；測試閥未關(guān)緊,；單向閥密封墊上粘連雜質(zhì),。
(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）故障處理：管道滲漏點補漏；檢修泄壓閥,；完全關(guān)閉測試閥,；清洗單向閥并清潔水箱及管道。
(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,、穩(wěn)壓泵規(guī)定時間內(nèi)不能恢復壓力
5. The regulated pump cannot restore pressure within the specified time
（1）故障原因分析：管道內(nèi)殘存空氣,；管道有滲漏,；高壓球閥滲漏；穩(wěn)壓泵出口壓力低,；穩(wěn)壓泵損壞,。
(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）故障處理：完全排除管道空氣；管道滲漏點補漏,；見下文高壓球閥滲漏故障處理方法,；調(diào)節(jié)穩(wěn)壓泵壓力調(diào)節(jié)螺絲；更換穩(wěn)壓泵,。
(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.
