Jinyu Machinery provides technical guidance, training, and machine maintenance & repair support, with a dedicated video series. This episode covers: Hydraulic Press Maintenance – Oil Change for Hydraulic Press Vacuum Pumps (focusing on the benefits of oil changes).
Benefits of Changing the Oil for Hydraulic Press Vacuum Pumps:
1. Improves vacuum performance and stability
2. Extends the service life of the vacuum pump
3. Reduces wear and prevents mechanical failure
4. Lowers noise and vibration during operation
5. Ensures better production efficiency and product quality
This hydraulic machine with vacuum function is from Jinyu Machinery.
It adopts a three-beam and four-column structure, with a thickened upper beam made of medium carbon steel and hardened columns, ensuring precise mold clamping. The upper and lower heating plates have extremely high flatness.
It is equipped with a high-end PLC intelligent control system and touch screen, which allows direct operation for both setup and production.
 
The machine features an optimized oil circuit design with high-quality hydraulic components, ensuring stable operation of the entire hydraulic system. It is also equipped with an air cooling device to effectively extend the service life of the hydraulic system.
 
The heating plates are manufactured with deep-hole processing technology, providing uniform heating and energy saving.
The fast vacuum pumping greatly improves product yield and reduces bubbles and defects.
