YUKEN PV2R Series Vane Pumps: Precision and Quiet Performance for Advanced Manufacturing Systems
PV2R series of vane pumps with high pressure and lower noise are high- performance products, which are developed and domestically produced by our company, featured by advanced performance, reasonable structure, good reliability, lower noise, ultra-low pulse and stable quality and so on. Precisely made, the product can be used in the equipment with high precision and low noise, and is widely used in cutting, plastic, leather, forging and engineering machinery fields, and the like.
Application in High-Precision Machine Tools
High-precision machine tools like CNC machining centers, precision grinders, and gear shaping machines need hydraulic systems that are very rigid, have very little vibration, and can control movement at the micron level. The PV2R series pump is widely used for the following purposes:
1. Spindle Clamping and Tool Changing Systems
The PV2R pump provides steady hydraulic pressure to the chuck actuators and automatic tool changers, making sure the clamping force is always the same and the response is quick. This helps prevent small slips of tools or workpieces that can happen when pressure changes, which keeps the machining precise.
2. Hydraulic Balancing for Guideways and Ball Screws
In heavy-duty cutting machines, the PV2R pump provides constant pressure to hydraulic counterbalance cylinders, enhancing the performance of components such as saddles and tables. This reduces the load on motors and enables high-speed, precision positioning.
3. Hydrostatic Bearing Lubrication
In ultra-precision grinding or milling machines, hydrostatic spindle systems need a steady and constant oil film pressure. The low-pressure pulsation from the PV2R pump helps reduce oil film oscillation, which stops surface finish issues like chatter marks.
Made with very accurate parts and a special blade shape, the PV2R pump reduces pressure changes and shaking. This helps it run quietly and smoothly, which is important for machines that need a lot of precision, like CNC grinders, measuring tools, and very fine injection molding machines. It also runs quietly, making it a good choice for places like cleanrooms, labs, and automated factories where noise levels are closely managed.
