When we use the pump, in order to maintain its performance and avoid operating problems, there are some maintenance and daily inspection methods that we need to understand. The following will introduce how to maintain and inspect the pump to extend its service life and reduce maintenance costs.
Based on differences in initiative, the types of maintenance are mainly divided into corrective maintenance and preventive maintenance.
What Is Corrective Maintenance?
Corrective maintenance: When the pump leaks, reduces efficiency, stops, or the motor trips, resulting in production losses, spare parts must be quickly purchased or installed in an emergency to restore the equipment system to an operational condition.
What Is Preventive Maintenance?
Preventive maintenance: Routine or periodic (hourly, daily, weekly, monthly, yearly) scheduled inspections designed to keep equipment in its current condition and prevent functional failures by disassembling devices and replacing seals (such as gaskets) or mechanical shaft seal) and check the wear of external and internal parts of the pump.
In addition to some inspection steps before and after starting the pump to ensure that the pump can operate normally, routine preventive maintenance is also a key point in protecting the pump.
Routine Inspection of Pump:
- Whether the pump body, connecting seat, and base are corroded or damaged.
- Is there any leakage in the connection between the pump and the pipeline?
- Is there any damage or corrosion on the surface of the motor?
- Whether the pump is operating normally and whether there is any abnormal noise or vibration.
- Confirm the flow rate and pressure at the inlet of the pump.
- Confirm the flow rate and pressure at the pump outlet.
- Confirm the height of the liquid in the tank.
- Whether the motor current value is within the rated range.
If spare parts are available, regular test runs are also required to check whether they can operate normally.
Regular Pump Inspection:
(Depending on usage conditions and hours, testing should be performed approximately every 3 to 6 months)
- Front cover, back cover
Check whether there are cracks, abnormal wear, crystals or foreign matter attached. - Gasket
Confirm whether there is deformation, corrosion or swelling. - Impeller and internal magnet
Confirm whether there are scratches or cracks, bearing cracks or crystals, bearing wear or tear marks, impeller deformation, etc. - Axis
Whether there are scratches or cracks. - Back cover
Check whether there is corrosion, cracks, holes or scratches.
In addition to the above maintenance and detection methods, preventive maintenance also includes the use of monitoring technology to determine the current operating status of system equipment. To correct pump problems before they occur, you can use PTCXPUMP idle protector to monitor the current or power of the pump motor when it is running. When the current is too high or too low, it will immediately issue a warning or automatically shut down. This function greatly reduces pump failures. probability and maintenance costs.
Considering preventive maintenance issues, PTCXPUMP acid and alkali resistant sealless magnetic pump Simple structure and convenient maintenance. Coupled with its high durability, it can reduce the cost of preventive and corrective maintenance.
