Notes on installation and maintenance of deep well pump

In order to guarantee the normal and reliable operation of deep well pump, prolong the service life and reduce the accidents in use, it is necessary to strengthen the deep well pump in the deep well well. In order to prevent the deep well from being damaged, Of the maintenance, regular deep well pump and its control system for a comprehensive maintenance.
The installation of the deep well pump is carried out in the following order:
(1) lifting should pay attention to the protection of cables to prevent damage, the lifting device used crane lifting weight should be greater than the weight of the deep well pump, and leave enough room.
(2) measured with a 500 volt megger insulation resistance of the motor shall not be less than 150 megohms, and turn the wheel to turn the impeller should be free without jamming phenomenon.
(3) first connected to the short pipe in the check valve body, with a pair of plywood installed in the short pipe under the flange, and then use the 25-ton truck crane gently lift the pump into the well, the clamping plate Fell on the covers.
(4) with another pair of plywood clamped long water pipe hanging and short water pipe connection, and then remove the first pair of plywood lifting another long water pipe, so repeated installation is completed, and then cover the plywood will be fixed In the manhole cover, the final installation of bending water pipes, valves, water pipes, deep well pump.
(5) during the installation of the two water pipes between the flanges should be a good cushion pad, tighten the bolts should be tightened on the cable to be tied to the water pipe flange; prohibit the pump cable as a sling Use, but not allowed to bruise the cable.
Start the submersible pump, should be smooth, no vibration and abnormal sound, observe the motor running current and line voltage before and after the start of any significant fluctuations.
