The centrifugal pump is rear-opening, so it is not necessary to remove the suction and discharge pipes when removing the pump cover and impeller. The suspension is equipped with two ball bearings, which are lubricated with oil or grease. The pump is directly driven by a motor through an elastic coupling. The vortex chamber, the foot, the inlet flange and the outlet flange are integrally cast. Clear water centrifugal pump has simple structure. First, ensure that the pump is used within the rated range, and it can’t run with no load. Pay attention to avoid cavitation and steam condensation, strengthen inspection and replace worn seals in time. After z, pay attention to the following. Project, you can master the correct method of use, extend the service life of the pump.
Check whether the pipes and joints of the clean water centrifugal pump are loose. Turn the clear water centrifugal pump by hand to see if it is flexible. Add bearing lubricating oil into the bearing body, observe that the oil level should be at the center line of the oil standard, and replace or replenish the lubricating oil in time. Unscrew the water guide plug of the clear water centrifugal pump body and fill it with water guide. Close the gate valve and outlet pressure gauge of the water outlet pipeline. Inch the motor to check whether the motor rotates correctly. Start the motor. After the clean water centrifugal pump runs normally, open the outlet pressure gauge to see if the pressure is appropriate, then gradually open the gate valve and check the motor load. As far as possible, the flow and lift of the clean water centrifugal pump should be controlled within the range marked by the sign, so as to ensure that the centrifugal pump runs at Z high efficiency point and obtain Z large energy-saving effect. During the operation of Qingshui heart pump, the bearing temperature shall not exceed 35℃ of the ambient temperature, and the Z-high temperature of Wuxi welded pipe shall not exceed 80℃. If abnormal noise is found in the centrifugal pump, it should be stopped immediately to check the reason.
When stopping the clean water centrifugal pump, first close the gate valve and pressure gauge, and then stop the motor. Clean water centrifugal pump should change the lubricating oil every 100 hours in the first month of operation and every 500 hours thereafter. Regularly adjust the packing gland to ensure the normal dripping in the packing cavity. Check the wear of the shaft sleeve regularly, and replace it in time when the wear is large. When clean water centrifugal pump is used in cold winter, after stopping, it is necessary to unscrew the drain plug at the lower part of the pump body to discharge the medium. Prevent frost cracking. If the clean water centrifugal pump is not used for a long time, the Wuxi welded pipe should be disassembled, the water should be dried, the rotating parts and joints should be coated with grease and installed correctly.
The product structure is simple. First of all, we should ensure that the pump is used within the rated range and cannot run at no load. Second, pay attention to avoid cavitation and steam condensation, strengthen inspection and replace worn seals in time. After z, pay attention to the following. Project, you can master the correct method of use, extend the service life of the pump. Hainan electric network
