The submerged slurry pump is a single-stage, single suction cantilever structure. The hydraulic components of the pump are connected by bearing seat, support plate and connecting pipe. The liquid is discharged from the liquid outlet pipe. The impeller of the pump is a semi open impeller, and the mixing blade is set at the inlet extension of the impeller blade. The main characteristics of the pump are that the pump shaft in the submerged part has enough rigidity, and there is no bearing between the impeller and the pump shell, Without shaft seal, it can transport media with large concentration of fixed particles.
The length of the pump inserted into the liquid is between 800-3000. If necessary, it can be equipped with a suction pipe. The drive is installed on the motor base and support base by vertical motor, and connected with the pump by coupling. Submerged slurry pump is also a kind of centrifugal pump. In order to meet the needs of production, it is designed as a single-stage single suction cantilever structure. It has high working efficiency and good conveying effect. The following Zibo Xiaochang Machinery Manufacturing Co., Ltd. will introduce the matters needing attention in the use of submerged slurry pump. First of all, when starting and stopping the submerged slurry pump, pay attention to observe whether the installation foundation of the pump is stable, such as bolts, etc. Check whether the axial clearance of the pump has been adjusted, and whether the selection direction of the motor is correct.
When starting the motor, open the cock of the pressure gauge. When the pump is working at full speed, adjust the opening of the gate valve to the required range. When the pump stops working, stop the motor first, and then close the pressure gauge cock. If the pump stops running for a long time, the pump should be disassembled, wiped clean, coated with anti rust oil and properly stored. When the submerged slurry pump is running, pay attention to the temperature of the pump bearing, which should not exceed the external temperature of 35 degrees, but the maximum temperature should not exceed 75 degrees. The oil cup shall be filled with calcium base grease to ensure normal lubrication of the bearing. The grease in the motor support oil cup should be replaced within the first month of operation or after 100 hours of operation, and then every 2000 hours of operation. Check the elastic coupling regularly and pay attention to the temperature rise of motor bearing.
