The damaged section of the drop pipe should be replaced. Need to rewind the coil. Fuse overload or circuit breaker trips when motor is started : CAUSE OF TROUBLE: HOW TO CHECK: HOW TO CORRECT: 1. Troubleshooting Tips - Submersible Pumps. 2. Insulation of the motor coil is leaking. Have you checked the voltage while the pump is running? This is extremely efficient because the pump uses the head of liquid in which it is submerged to operate and no energy is spent in drawing the liquid into the pump. Level of water in well is too low: Restrain the output flow of the submersible pump, then wait for the well to recover. My submersible pump is 1hp and it is taking high current (13 amp) my submersible motor is 1hp motor Due to which it closed automatically after 5 minutes. Make sure the voltage is within the min/max range prescribed by the manufacturer. If the amp is signifintly heigher than the rated current there are three probable reason: 1. Problem with submersible pump motor . Drop line has a leak: Raise the pipe on the submersible pump and check for leaks. If you have little or no current on the start winding, you likely have a bad run cap. If this does not work, the switch on the submersible pump needs to be replaced. Understand what an Ohmmeter is and how to properly use it in order to troubleshoot a submersible motor. I have 260 ft boring and bore of 1 inch for which I use 1 hp motor.
Did you properly size the wire? The motor is cooled by the liquid around it, preventing overheating. Submersible Pumps It covers products for drainage and water supply applications as well as centrifugal sewage pumps, tubular casing and vertical immersion pumps, submerged propeller units, submersible borehole pumps, submersible motor pumps and a solid separation system. Incorrect line voltage: Check the line voltage terminals in the control box (or connection box) with a voltmeter. A submersible pump operates by pushing, as opposed to drawing, liquid during the pumping process. That means it's a short circuit in coil. Have you checked the amperage on the start and run winding?
