1. Edit variable vane pump characteristics can have automatic high-speed traffic and compensation under the pressure setting, less than quantitative vane pump power consumption, low heat, is a high-efficiency energy saving vane pump for system design engineers in high efficiency The circuit best choice. 2. The balance of quiet operation, especially for machine tools and indoor requirements. 3. containing pressure adjustment mechanism, the system can not apply direct pressure regulator and motor assembly easy. 4. A wide range of different pressures and flow range, for arbitrary choice. Under conditions of constant speed, constant output flow pressure can be mobilized for the variable vane pump, constant pressure and flow are not adjustable for quantitative vane pump. Their biggest difference is that the variable vane pump shaft is installed then the heart. After speaking simple quantitative vane pump speed is selected, he will surely flow and pressure of the variable displacement pump, it can not recuperate. Output flow variable vane pump can pump hydraulic system based on pressure changes (external load size) variable * care, conditioning automatically flow, high output pressure is low flow, low pressure output flow, so that he can save hydraulic the number of components, thus simplifying the hydraulic system, and can reduce heating oil. The disadvantage is that the flow pulsation serious hydraulic system pressure poised, short life of the pump, pump bearings easily broken variable pump * Specialist, because he was then the heart of the installation, and the big pump bruit. By conditioning eccentricity vane pump, piston slide angle can be achieved through the conditioning variables. Quantitative vane pump works: sealed volume of the stator and rotor valve plate is composed of blade divided into several, one week per revolution of the rotor, each sealed space complete two suction and pressure oil, so called quantitative vane pump. Variable vane pump works: the variable vane pumps from e by changing rotor and stator eccentricity to conditioning pump flow variable pump * maintenance of telephone, the hydraulic system at work feeding the energy use of justice, the effectiveness of high oil temperature or small. Eccentric actually change from e achieved only by moving the stator, the rotor and shaft position is the prime mover of the axis defined by the variable displacement pump * Maintenance | Variable Pump | Hydraulic from Jinan Jing Jing Chong Chong Hydraulic Machinery Co., Ltd. available.
