Careful observation diving sand pump wiring diagram, be able to find serious problems in wiring. Design specification: PE line and N line if combined into one, in order to prevent fracture when copper wire, use cross-section of 10mm wire. This example uses 4mm2 wire, it is easy to break and electric shock. Construction of electricity provision: PE line and N line can not be combined, should be separated; submersible pumps for electricity, should leakage protection. This example only air switch, and therefore unsafe. Any incident afterwards easy, but beforehand find it difficult to ZJQ150-60-75 pumping sand pump, improve the technical quality of construction workers is the key. Slurry submersible slurry pump operation precautions work, the pump needs to be placed on land ZJQ200-45-75 pumping sand pump, suction pipe on the water, but also need irrigation pump starts. Under the mud pump and liquid slurry pump due to structural limitations, the work needs to be placed above the water ZJQ200-55-75 motor pumping sand pump, pump into the water, it must be fixed, or pumping sand pumps, motors fell into the water cause the motor to be scrapped. And because the major axis length is generally fixed, so the pump installation more difficult, the application of occasions by many restrictions. _ Pumping sand pump sludge pump _ZJQ150-55-75 pumping sand pump is provided by Shijiazhuang-Pump Co., Ltd. faction. _ Pumping sand pump sludge pump _ZJQ150-55-75 pumping sand pump is the Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image Contact phone, for the latest information, Contact: Manager Xu.
