Users who often use Stainless Steel Submersible Pumpwill experience more or less trips, then you will get electricity, which must be caused by a short circuit, which is also a reason. In addition to many reasons that affect the trip of the submersible pump, your current is unstable or the switch of the submersible pump is poorly connected. But sometimes we find that these reasons are not the case.
The upper part of the submersible motor shaft is equipped with a labyrinth sand control device and two back-mounted skeleton seals to prevent quicksand from entering the motor. The submarine motor adopts water-lubricated bearings, the lower part is equipped with a rubber regulating film, regulating springs, regulating the pressure chamber, and regulating the pressure changes caused by temperature; the motor windings are insulated by polyethylene, the nylon sleeve is water-resistant electromagnetic wire, and the cable joint technology is used to insulate the joints Scrape off the paint layer, connect, weld firmly, and wrap a layer with raw rubber. Then wrap it with 2-3 layers of waterproof tape, and stick the rubber layer (bicycle tire) with 2-3 layers of waterproof tape or glue to prevent water seepage.
The trip of the submersible pump may be related to the cable. The polarity of the current transformer is connected correctly. After troubleshooting the causes of equipment failures and wiring errors, the differential protection operates during the start of the motor, which indicates that during this process, the differential current in the differential circuit exceeds the differential relay setting. The above can be considered as common causes of submersible pump failures. We can communicate with Submersible Pump Factoryin a certain order, first carry out overall troubleshooting, and then carry out partial troubleshooting.
