Pump life cycle management and maintenance
The life cycle management and maintenance of pumps are the key to ensuring their long-term stable operation, improving production efficiency and extending service life. The following is a brief overview of the life cycle management and maintenance of pumps:
First, regular inspection and maintenance are the basis of pump life cycle management. This includes checking the current, voltage and outlet pressure of the submersible electric pump every hour to ensure that it operates within the allowable rated working range. At the same time, a comprehensive preventive maintenance should be carried out at least once a year, and the wear of key components such as impellers, sealing rings, sleeves, couplings, etc. should be checked in detail, and the seriously worn parts should be replaced in time to prevent them from happening.
Secondly, the cleaning of the pump should not be ignored. It is easy for debris and dirt to accumulate inside the pump body and impeller, which affects the flow and head of the pump, so they need to be cleaned regularly. In addition, check whether the bearings and seals are worn or damaged, and replace them in time if necessary to ensure the normal operation of the pump.
Furthermore, different maintenance measures need to be taken for different types of pumps. For example, for oil bearings using lubricating oil, it is necessary to regularly observe the oil level and add oil when necessary, and clean and change the oil once a year; for bearings using grease, the oil needs to be changed once every certain working time. For special types of pumps such as submersible pumps and sewage pumps, special attention should be paid to the wall thickness and strength of the outlet pipes, and severely corroded pipes should be replaced in time, and stainless steel pipes should be used to extend the service life.
Finally, the maintenance of the pump control cabinet and related equipment is also an important part of life cycle management. It is necessary to regularly check whether the electrical components such as the conversion switch, start and stop buttons in the control cabinet are flexible and reliable, and clean the dust inside and outside the switch box. At the same time, it is also necessary to pay attention to the running sound of the pump and the condition of the power cord to ensure the safe operation of the pump.
