How to Maintain a Gear Pump
Maintaining a hydraulic gear pump involves several key steps and considerations:
Regular Inspection and Maintenance: Regularly check the operating condition of the hydraulic pump, including any abnormal noises, vibrations, or leaks. If any abnormalities are found, stop the machine immediately for inspection and troubleshooting.
Cleaning and Replacing Hydraulic Oil: Regularly clean and replace the hydraulic oil to keep it clean. Replace the hydraulic oil after the first 500 hours of operation, with a maximum replacement interval of 2000 hours. Also, regularly replace the hydraulic oil and filters to ensure the system operates efficiently and safely.
Checking Seals and Filters: Regularly replace seals and filters to ensure the system's sealing and filtration effectiveness. The lifespan of seals is generally one and a half to two years, so timely replacement is necessary.
Attention to Operating Environment: Avoid working in excessively harsh environments, such as high temperatures, high humidity, or areas with a lot of dust, as these conditions can affect the pump's performance and lifespan.
Measuring and Adjusting Oil Pressure: Accurately measure the oil pressure in the system and adjust it according to specific requirements to prevent system failures and improve work efficiency.
Daily Inspection and Maintenance: Daily checks should include ensuring that connections are tight, there is enough lubricant in the oil tank, and the air filter is functioning properly. Weekly maintenance includes replacing all oil, cleaning the crankcase, and wiping clean the intake pipes and oil pan. Monthly maintenance includes checking the valve clearance, pressure relief valve, and seals.
Annual Overhaul: After one year of operation, conduct an annual overhaul, including inspecting and straightening rotating parts and replacing worn parts.
By following these steps, you can ensure the efficient and safe operation of your hydraulic gear pump, extending its lifespan and maintaining its performance.
