The main function of the manual pump on the roller is to provide hydraulic power for and regulate the system pressure of , ensuring the normal operation of the equipment.
Hydraulic power source
The manual pump converts mechanical energy into hydraulic energy through human drive (such as handle operation), providing a stable flow of pressurized liquid for the hydraulic system of the roller. For instance, a plunger pump achieves oil suction and discharge by changing the sealed working volume, providing power support for functions such as vibration and compaction.
Pressure control and safety protection
When the system pressure exceeds the preset value (such as 63MPa), the relief valve will automatically open to relieve the pressure and prevent damage to the equipment due to excessive pressure. Meanwhile, manual pumps are usually equipped with pressure relief valves and fusible plugs, which can quickly relieve pressure in emergency situations (such as when the temperature rises above 75ºC or in case of fire) to ensure the safety of the equipment.
Maintenance and upkeep
Regularly checking the cleanliness of the hydraulic oil, oil temperature and oil pressure parameters, replacing the filter and cleaning the oil tank/pipeline can extend the service life of the manual pump and reduce the failure rate. This is crucial for maintaining the stability of the hydraulic system of the road roller.
