Installation and operation knowledge of stainless steel corrosion-resistant submerged pump

Disassembly and assembly of stainless steel corrosion-resistant submerged pump 1 If the impeller is replaced or inspected, the outlet valve can be closed, the flange connecting bolt and the bottom plate connecting bolt can be removed, and the pump can be lifted out of the container with a lifting tool 2 Place the bottom plate vertically on the fixed bracket, remove all the bolts of the pump body, take out the pump cover and impeller nut, and tap the pump body with double hammer to remove the impeller 3 When replacing the rolling bearing, the bottom plate will not move As long as the motor and corresponding bracket are removed, the pump coupling, 31 cover and circular Lei nut are removed, and the bearing body is taken out 4 The order of assembly and disassembly is opposite Pay attention to the concentricity of the accessories on the shaft Stainless steel corrosion-resistant submerged pump installation, use and maintenance 1 After the pump is assembled, turn the coupling to see if it can rotate flexibly Check whether there is metal friction sound and whether the screw of each part is tightened 2 Check the concentricity of the pump shaft and the motor shaft The difference between the upper and lower coupling outer circles shall not exceed 0.1mm, and the end clearance of the coupling shall be 1-2.5mm 3 The distance between the suction port of the pump and the bottom of the container is 2-3 times of the suction diameter The distance between the pump body and the wall shall be more than 2.5 times of the diameter 4 The outlet pipe of the pump shall be provided with a bracket, and its weight shall not be supported on the pump 5 Check the rotation direction of the motor to make sure that the rotation direction of the pump conforms to the indicated direction 6 Close the gate valve on the outlet pipe and connect the cooling water pipe 7 Start the motor, slowly open the idle valve of the outlet pipe to the necessary position, and put it into normal operation 8 Check the condition of pump and motor frequently The temperature rise of bearing shall not exceed 75 ℃, and sufficient grease shall be added in the bearing box
