عربىVickers Hydraulic Vane Pumps' performance optimization and energy saving methods are mainly achieved by improving pump efficiency, reducing energy loss, improving control strategies, and using appropriate accessories and system design.
Choose the appropriate pump model according to the maximum flow and pressure requirements of the hydraulic system, and avoid too large or too small pump capacity. An oversized pump may cause unnecessary energy waste, while a too small pump may not meet system requirements.
Ensure that the pump's operating pressure matches the needs of the hydraulic system. Avoid overload, which not only improves the pump's efficiency but also extends the pump's life.
Internal leakage in the pump will lead to reduced efficiency, especially under high pressure and high flow conditions. By improving the material, design and assembly process of the seals, reducing internal leakage, the efficiency of the pump can be effectively improved.
Ensure the precise fit of the blades with components such as the stator and rotor, reduce the gap, and thus reduce internal leakage.
Using a variable speed drive (such as a frequency converter or electronic control system) can automatically adjust the pump speed according to the system load and reduce energy waste. Providing sufficient flow only when needed can significantly reduce system energy consumption.
It can be equipped with a flow control valve to ensure the accuracy of flow control, thereby avoiding excess energy consumption.
Selecting materials with low friction coefficients and high-precision processing technology to reduce friction losses between blades, stators and rotors can improve the efficiency of the pump.
Ensure the cleanliness and appropriate viscosity of the hydraulic oil to reduce internal friction. Replace the hydraulic oil regularly to avoid pollutants and impurities that cause increased friction resistance.
High-viscosity hydraulic oil will increase the energy loss of the pump. Choosing low-viscosity oil can effectively reduce friction losses. Using hydraulic oil with good anti-wear performance can also reduce wear inside the pump and improve the efficiency of the pump.
Hydraulic oil used for a long time will be contaminated, resulting in decreased fluid viscosity and performance. Regularly replacing hydraulic oil and keeping the oil clean can reduce energy losses caused by oil quality problems.
Optimize oil circuit design
Optimize the pipeline layout of the hydraulic system to avoid excessively long pipes, too many elbows and unnecessary connection points to reduce the pressure loss of the fluid in the pipeline.
The capacity of the oil tank and the oil circuit design should be able to ensure the fluidity and pressure stability of the hydraulic oil to avoid energy loss caused by excessive pressure fluctuations in the system.
The system's operating pressure should be adjusted according to the application's load requirements to avoid unnecessary high-pressure operating conditions. High-pressure operation will increase the pump's energy consumption and increase pump wear.
Install appropriate pressure regulating valves to ensure that the system operates within the necessary range to avoid excessive system pressure.
Using a variable frequency drive (VFD) can adjust the pump's speed according to load requirements, so that the pump can automatically adjust the flow and pressure under different working conditions, thereby achieving energy saving. The inverter can automatically adjust the speed according to changes in the load to avoid wasting energy when the pump is running under low load.
Through the PLC control system, the working status of the pump and the pressure, flow and other parameters of the hydraulic system are monitored in real time, and the operating parameters of the pump are adjusted according to demand to avoid unnecessary energy consumption.
Using closed-loop control in the hydraulic system, real-time feedback of flow and pressure data, the system can automatically adjust the pump's output power, optimize working efficiency, and avoid oversupply or undersupply.
These not only help to save energy and reduce emissions, but also extends the service life of the pump, reduces the failure rate, and improves the overall operating efficiency of the system.
