[ Vertical Axial Flow Pump Maintenance] Method Sharing:
First, the installation of the pump unit must be accurate and reliable, and there must be no obvious vibration during operation. If there is an abnormal noise when pumping the axial flow pump, or if the bearing is hot (temperature is higher than 60 ° C) and the water leakage at the shaft seal of the pump is greater than 60 drops per minute, the cause must be identified and the fault removed in time.
The second is the daily screwing screws, such as stuffing gland screws, irrigation plugs, etc., should be disassembled with a suitable wrench and reasonable torque. Do not use hand pliers to prevent thread or nut sliding; other screws can be used in Apply some lubricating oil on it or use regular oil cloth to wipe the rust; if the drain screw is not used frequently, it will easily rust, so after buying the new water pump, you should unscrew the drain plug first, and apply some oil and white lead oil on the screw thread. Change the new oil two or three times a year.
Thirdly, the axial flow pump lubricated with oil should be replaced once a month; the oil lubricated with butter should be replaced every six months. It should be noted that the axial-flow pump uses calcium-based grease and the motor uses sodium-based grease. Because the sodium-based grease is hydrophilic, it will emulsify into foam when it meets water on the axial flow pump, while the calcium-based grease is afraid of high temperature. It is used on the motor, and it will be easy to lose when the temperature rises.
Fourth, it is not possible to pump water containing too much sand, so as to avoid the premature wear of impellers, rings and shafts, and also to prevent water shortage operation. Water shortage will damage the water seal, and it is easy for the axial flow pump to leak or not even produce water.
Fifth, after the end of the irrigation and drainage season, the pump should be carefully cleaned and inspected immediately. If damaged or deformed parts can no longer be used, they should be repaired or replaced in time. Fill the lubricated parts with suitable oil. Store in a dry place.
