Application: T7E Vane Pump


     How do you get a large hydraulic press to open quickly, smoothly and also efficiently? You provide it with a flow of oil that is increased from small to large and back to small again, ramp this flow quickly and provide it at a pressure no greater than required to accelerate the weight of the platen. This is done by using a “Drive Controlled Pump”. In one particular application, a Parker T7E-085 (16.4 cubic inch per revolution) vane pump, a 75 horsepower electric motor and an electric motor AC drive unit (frequency controller and regulation electronics) were used. No oil was forced over relief or throttle valves; thus, little energy was wasted! The electric motor was controlled by the AC drive unit to increase the speed of the pump drive (thus increasing its output flow) over a short period of time, getting the platen moving quickly and smoothly. At 1800 RPM this pump produces 125 GPM of fluid. Then, the AC drive unit was used to decrease the speed of the pump drive over a short period of time, bringing the platen to a stop. Thanks to the very wide range of speed (up to 3000 rpm) and the high operating pressures (up to 320 bar), the “Drive Controlled Pump” system solution can be tuned exactly to a customer's specific requirements. The robust double lip design makes the Parker vane pump impervious to particle contamination and maintains a high degree of efficiency in the long term. Also, the design of Parker’s vane pump, with its two opposing pressure chambers, prevents lateral forces working on the drive shaft, eliminating mechanical stress within the pump and providing a long reliable working life.
