3. diving sand pump excessive vibration? The main reason: electric rotor imbalance; coupling bad combination; bearing wear bending; section of the rotating parts loose, cracking; pipeline stent is not strong and so on. Can be taken separately adjust, repair, strengthening, straightening, replacement approach. (2) sand pump start diving. ① fully open the inlet valve. ② Close the discharge pipe valve. ③ starter motor, ZJQ25-40-15 slurry pump, the pump is operating properly observed. ④ regulated outlet valve opening to meet the required conditions, such as a user in diving sand pump fitted at the outlet of the flow meter or gauge, should be made by adjusting the pump outlet valve opening operation at the rated point performance parameters listed in the table , ZJQ100-16-11 slurry pump, such as when the user does not install the pump outlet flow meter or gauge, ZJQ50-26-15 slurry pump should be by adjusting the outlet valve opening, Neijiang slurry pumps, submersible pumping determination sand pump motor current, the motor runs at the rated current, otherwise it will cause submersible sand pump overload (ie large current operation) cause the motor to burn out. ZJQ50-26-11 Slurry | Neijiang slurry pumps | submersible slurry pumps provided by the Shijiazhuang-Pump Co., Ltd. faction. Shijiazhuang-school Pump Co., Ltd.
