Under normal conditions, it is recommended to replace the lubricating oil in the bearing housing every 6 months as a part of regular maintenance. This ensures that the oil remains in optimal condition for effective lubrication. Thus, removing and replacing the lubricating oil periodically is essential for the smooth functioning of the bearing.
Next, it is essential to ensure that the motor is completely dry to avoid any moisture that may damage the motor and compromise the equipment's functionality and safety measures.
During the severe cold season, it is important to prioritize the connection of cooling water at the seal after stopping the pump to avoid freezing. If freezing occurs, the water can be heated to thaw the seal. Once the seal is thawed, the coupling should be manually rotated until it moves smoothly. After this, the standard starting steps can be followed to initiate the pump's operation.
Before starting the pump, it is recommended that the cooling water device is connected to avoid overheating. In case it cannot be connected, the pump can still function but make sure to connect it again once the pump is operating normally. Alternatively, the cooling water can also be stopped if the situation does not permit it.
The closed pressure operation, also known as the operation of the outlet valve, should be conducted with minimal duration for all-plastic pumps or plastic-lined pumps. It is recommended to limit the time for normal temperature medium to 5 minutes and for high temperature medium to 2 minutes. It is crucial to adhere to these guidelines in order to ensure the efficient and safe functioning of the pumps.
Furthermore, it is important to note that the inlet and outlet pipelines of the pump should not exert too much weight on the system as it may cause damage. To achieve optimal performance, it is ideal to have a shorter inlet pipeline. Additionally, the distance between the outlet of the plastic-lined magnetic pump and the valve should be minimized, thus reducing potential logistical issues such as vertical height constraints.
