Multi-stage pump manufacturer Changsha pump factory direct multi-stage pump multi-stage pump accessories mine pump mine drainage pump, multi-stage pump coal mine drainage pump high pressure pump, coal mine pump coal mine pump Changsha multi-stage pump manufacturers must be Note the following two points: 1. If the pump has any small faults remember not to let it work. If the pump shaft is completely worn after the filler to be added in time to damage the impeller. If the pump during the use of strong vibration occurred this time must be stopped to check what is the next reason, otherwise it will cause damage to the pump. When the pump valve leakage some people will use dry soil filled into the pump inlet pipe rushed to the end of the valve, this approach is not desirable. Because when the dry soil into the inlet pipe when the pump starts to work these soil will enter the pump, then it will damage the pump impeller and bearings, thus shortening the pump life. When the end of the valve leaking must take to repair, if it is serious then it needs to be replaced. 2. After using the pump must pay attention to maintenance, for example, when the pump is running out after the water pump to drain, it is best to remove the hose and then rinse with water. The tape on the pump should also be removed, and then rinse with water and dry in the light, do not put the tape on the dark and humid place. Pumps must not be stained with oil tape, not to be coated with adhesive tape some things. To carefully check whether there are cracks on the impeller, the impeller is fixed on the bearing is loose, if there is cracks and loose phenomenon to be repaired promptly, if the pump impeller above the soil should be cleaned. Pump and pipe connections must be well sealed, because if there are debris into the interior of the pump will cause damage to the pump on the bearing is also the focus of inspection, use the bearings to check whether there is wear and tear, if the pump time If the long ball bearing small ball will be broken, so when the pump after the best bearing is coated with a layer of lubricant to better protect the pump bearings.
