5. Installation and maintenance points
1. Installation precautions
–Installation location: It is recommended to install horizontally, and the oil suction port is lower than the oil level of the fuel tank to ensure good oil suction conditions.
–Connection requirements: The oil pipe is firmly connected to avoid leakage; the oil suction pipe is as short as possible and the diameter is sufficient to reduce resistance
–Coupling selection: Use elastic couplings to avoid excessive axial and radial deviations and reduce vibration transmission
–Exhaust operation: Sufficient exhaust is required before starting to prevent cavitation from causing noise and wear
2. Daily maintenance guide
| Maintenance items | cycles | Operation points |
|---|---|---|
| Oil inspection | Weekly / Check the cleanliness and oil level of the oil, keep the oil clean, and the oil level is within the specified range | |
| Temperature control / Continuous | Control the oil temperature at 30-55℃, and install a cooler if necessary to avoid excessive oil temperature and accelerate the aging of the seal | |
| Pressure monitoring / Daily / Install a pressure gauge to monitor the system pressure in real time to avoid long-term overpressure operation | ||
| / Seal inspection | Monthly / Check the shaft seal and O-ring, and replace it immediately if leakage is found to prevent oil pollution and loss | |
| Filter element replacement / Every 3 months | Regularly replace the oil suction and oil return filter elements to keep the oil clean and extend the service life of the pump | |
| / Regular maintenance | Annual / disassembly and inspection of the wear of key components such as blades, stators, rotors, etc., and timely replacement of wearing parts |
