一、 當抽沙泵出口有壓力但是壓力小于正常值范圍
1、抽沙泵長期沒有運行，使得葉輪、密封部位粘結，造成電機堵轉；開機前應盤動沙泵，確認轉動靈活再啟動。
2、抽沙泵本身缺陷，盤動時候出現死點，此事時應解體檢查沙泵的零部件是否有損壞情況，并及時更換損壞零件。
3、電氣故障，檢查電機及線路有無缺相故障，保護系統有無誤動作，保證電力系統頻率到正常值后試機。
二、當沒有壓力可能為以下情況：
1、管路瀉壓，可能為管路的某個部位有泄露造成瀉壓，從而是系統壓力減�。豢梢躁P閉吸沙泵出口閥門，檢查壓力情況。
2、缺水，管道內水源不足也是壓力不足原因之一，多是由于吸沙泵施工環(huán)境中有垃圾或雜草淤堵管路進口，此時開機后能聽到水泵噪音很大，逐漸關閉出口閥門這種聲音會逐漸減小。清理吸沙泵過濾網上的淤堵并提高工況水位。
3、葉輪腐蝕或者葉輪口環(huán)磨損；更換沙泵葉輪。
One, when the pump outlet pressure but the pressure is less than the normal range of values
1、抽沙泵長期沒有運行，使得葉輪、密封部位粘結，造成電機堵轉；開機前應盤動沙泵，確認轉動靈活再啟動。
1, pumping sand pump has not run for a long time, so that the impeller, sealing parts of the bond, resulting in motor blocking; boot before the disc moving sand pump, confirm the rotation and then start flexible.
2、抽沙泵本身缺陷，盤動時候出現死點，此事時應解體檢查沙泵的零部件是否有損壞情況，并及時更換損壞零件。
2, the limitation of the sand pump pumping, plate moving when dead point, the matter should be disintegration of parts of the sand pump check whether there is damage, and timely replacement of damaged parts.
3、電氣故障，檢查電機及線路有無缺相故障，保護系統有無誤動作，保證電力系統頻率到正常值后試機。
3, electrical fault, check the motor and the line has no phase fault, the protection system has the correct action, to ensure that the power system frequency to the normal value of the test machine.
二、當沒有壓力可能為以下情況：
Two, when there is no pressure may be the following:
1、管路瀉壓，可能為管路的某個部位有泄露造成瀉壓，從而是系統壓力減小；可以關閉吸沙泵出口閥門，檢查壓力情況。
1, pipeline leak pressure, may be a part of the pipeline leak caused by leakage, from the system pressure decreases; can be shut down the suction pump outlet valve, check the pressure.
2、缺水，管道內水源不足也是壓力不足原因之一，多是由于吸沙泵施工環(huán)境中有垃圾或雜草淤堵管路進口，此時開機后能聽到水泵噪音很大，逐漸關閉出口閥門這種聲音會逐漸減小。清理吸沙泵過濾網上的淤堵并提高工況水位。
2, water, pipe water shortage is also the pressure of the causes of the lack of one, mostly because of the sand suction pump construction environment with rubbish or weed clogging the import pipeline. At this time, the boot can hear pump noise is very big, and gradually close the outlet valve of the sound will be gradually reduced. Cleaning up the clogging of the filter net of the suction sand pump and improving the working conditions of the water level.
3、葉輪腐蝕或者葉輪口環(huán)磨損；更換沙泵葉輪。
3, impeller corrosion or impeller ring wear; replace sand pump impeller. |
