Proper maintenance and repair of electric pressure pumps are crucial for ensuring their long-term stable operation and extending their service life.

In maintenance, first and foremost, keeping the pump body and all components clean is crucial. Regularly clean the various parts of the oil pump, ensuring there's no dust or debris at valve points and around the plunger. Also, use hydraulic oil with the specified kinematic viscosity range for the working fluid, and strictly avoid using unsuitable liquids like alcohol, water, and glycerin. For electric pump lubrication, add or replace lubricating oil or grease as required by the equipment to ensure optimal lubrication of all components, reducing wear and friction. Moreover, the rubber hose is a component in electric pumps prone to aging, so its condition should be checked regularly. Replace it immediately if any signs of damage, bulging, or leakage are detected. Seasonal maintenance is also a vital aspect, including pipeline cleaning, replacing seals, and checking electrical components, to ensure the equipment operates smoothly.

In terms of maintenance, repairing electric hydraulic pumps involves various aspects, including the inspection and replacement of solenoid valves, regular oil changes, and the examination and replacement of worn-out parts. For instance, solenoid valves are critical components of electric hydraulic pumps; if they burn out, they need to be replaced promptly. Additionally, maintenance and care during operation are crucial, such as ensuring all air is drained from the axial piston pump elements before adding hydraulic oil after a prolonged shutdown.

In summary, by maintaining cleanliness, lubrication, regular inspections, and seasonal maintenance, the lifespan of electric hydraulic pumps can be effectively extended, enhancing the equipment's stability and reliability.
