The hydraulic pump serves as a critical component within a hydraulic system, transforming mechanical energy from the prime mover into hydraulic pressure energy. It functions as the oil pump in a hydraulic system, providing the necessary power for the entire setup. Hydraulic pumps typically come in three main types: gear pumps, vane pumps, and piston pumps. However, they can sometimes encounter issues like noise, which may stem from various causes and require specific troubleshooting steps.
One common issue is a clogged pump filter, which prevents it from effectively filtering oil. To resolve this, thoroughly clean or replace the oil filter to eliminate any accumulated dirt. Another potential problem arises when the oil level is low, causing the oil suction position to be too high and exposing the intake pipe above the oil surface. Refilling the oil reservoir and ensuring the oil suction position remains submerged can help alleviate this issue.
A lack of sealing between the pump body and the pump cover, due to missing paper gaskets or misalignment, can also lead to air leaks during operation. Inserting a paper gasket between these components and ensuring their alignment is precise (with a vertical error not exceeding 0.005mm) can prevent such problems. Additionally, if the pump shaft and motor coupling are not aligned properly, resulting in friction and distortion, adjusting their concentricity to ensure an error of less than 0.2mm will help restore optimal performance.
Another possible cause of noise could be insufficient gear meshing accuracy in the pump. Ensuring the gears achieve proper meshing through precision grinding is essential. If the pump shaft seal's skeleton becomes dislodged, leading to poor sealing, replacing the pump shaft seal with a qualified one is necessary.
Performance-wise, this hydraulic pump boasts an output pressure of 70Mpa, operates at 220VAC with 350W power, and can handle maximum and minimum working pressures of 70Mpa and 1.5Mpa respectively. Its fuel consumption stands at 2.5 liters, weighs 14kg, and measures 385x130x250mm. These specifications make it a robust choice for various hydraulic applications.
In conclusion, maintaining a hydraulic pump involves regular checks and maintenance to address potential issues promptly. Whether it’s ensuring proper filtration, aligning components correctly, or replacing worn-out seals, these efforts contribute significantly to prolonging the pump’s lifespan and enhancing its efficiency.
