Selection of high-pressure pump installation and use Selection of submersible pump used in well, must be selected according to their use, that is, for the pressure tank water supply should choose a small flow and submersible pumps; lift should be used for the water tower According to the size and lift of the water tower, you can choose to use a medium flow submersible pump; for farmland irrigation, in the case of a suitable head, try to choose a large flow submersible pump. But also according to the caliper size, the amount of water and sediment concentration and other specific conditions to choose the appropriate submersible pump specifications. Installation According to the instruction manual, according to the specified procedures and requirements for installation. In strict accordance with the provisions of head installation, to prevent low-lift, over-flow motor overload operation, burning motor. Installation depth, the general should ensure that the electric pump bottom to the bottom of the distance of not less than 3 meters. Pump installation, should ensure that all of the motor cavity are filled with water. After using the electric pump is installed, do not immediately boot, you must first use the power, starting equipment, instruments, etc. to check, confirm the correct before the trial run. After starting the instrument check the pump voltage, current, until everything is normal before it can be put into work. Before switching on every class, check the power supply voltage and insulation resistance; check the working current and pump operation after starting the machine, and find out the problem is solved in time, and it is forbidden to run the electric pump sickly. Submersible pump open and stop, should not be too frequent, stop immediately after the restart, you must wait for the tube after the return of water can be restarted. Submersible pump failure, we should first check whether the peripheral equipment problems, such as the power is normal, well water level dropped too much, the pump is leaking water. After checking the correct pump can be raised out of the well. Submersible pump operation for 2 years to conduct a comprehensive overhaul, replacement of worn parts. Any maintenance pump, should be sent to the professional maintenance point of maintenance, can not be replaced with shoddy parts. Submersible pump for more than one year, should be put out of the well, after a comprehensive overhaul into dry, non-corrosive indoor. To drain the motor memory water, rust, moisture.
