PV2R24-65-136, PV2R24-65-153 Installation Notes
Regarding the samples and installation precautions of the double pumps PV2R24-65-136 and PV2R24-65-153, the following is the content sorted out based on relevant information:
1. Installation precautions
①Alignment of pump shaft and drive shaft:
During installation, the alignment of the pump shaft to the drive shaft should be ensured to reduce radial and axial loads. It is recommended to use a flexible coupling to achieve this.
The misalignment between the pump shaft and the drive shaft should be controlled within the range specified by the manufacturer.
②Oil suction port pressure:
When the pump is installed above the oil tank, make sure that the height of the oil suction port from the liquid level does not exceed the maximum value specified by the manufacturer to avoid cavitation.
The flow rate at the suction port should be controlled within the range recommended by the manufacturer, and it is usually recommended not to exceed 1m/s.
③ Exhaust:
When the pump is restarted after installation or after a long period of non-use, cavitation may occur. Therefore, it is recommended to install an exhaust valve at the oil discharge port or loosen the connection of the oil discharge port pipe to discharge the air in the pipe.
④Rotation direction:
Make sure the rotation direction of the oil pump is consistent with the direction indicated on the nameplate. If the rotation direction is wrong, it may cause damage to the oil pump or deterioration of performance.
⑤Sealing and cleaning:
The oil inlet connection flange, joints and the entire oil suction pipeline must be strictly sealed to prevent air leakage. Air leakage will cause noise, system vibration and may reduce the service life of the pump.
During disassembly and assembly, attention should be paid to the cleanliness of the working surface and ensure that the oil is well filtered during operation.
⑥Oil temperature and viscosity:
The temperature and viscosity of the oil should be within the range specified by the manufacturer. Generally, the temperature of the oil should not be too high and the viscosity should be within a certain range to ensure the normal operation and performance of the oil pump.
⑦Installation location:
The vane oil pump can be installed in any direction (preferably horizontally), but the installation position should be stable and easy to maintain.
⑧Inspection and testing:
After installation, necessary inspections and tests should be carried out to ensure that the performance and safety of the oil pump meet the specified requirements.
In summary, when installing YUKEN type hydraulic oil pumps PV2R24-65-136 and PV2R24-65-153, the manufacturer's installation guidelines and precautions should be carefully followed to ensure the normal operation and long-term stability of the oil pump. At the same time, it is recommended to regularly maintain and inspect the oil pump to extend its service life and improve performance.
