Vacuum Ejector

The SMPi/SCPi Vacuum Ejector from Schmalz allows the user to optimise work processes, utilise resources more efficiently, dramatically reduce operating costs and help to protect the environment. This can be shown by comparing the efficiency of this system with that of a conventional vacuum ejector. With a cycle time of 15 seconds, the compressed air consumption is the same for suction and blow-off of the workpiece. The most significant difference between the two vacuum ejectors is the “suction” function during the actual transportation of the workpiece. The conventional ejector must be in operation for 4.22 seconds in order to safely secure the workpiece. The Schmalz SMPi/SCPi vacuum ejector requires only 0.3 seconds of switch-on time. This is facilitated by the integrated energy saving function: It interrupts vacuum generation as soon as a safe vacuum value has been reached. Vacuum generation is switched back on only once the value exceeds the preset minimum vacuum value. The length of the “suction” function, or the time during which the vacuum generator is operational over the course of the complete cycle, lasts only 1.19 seconds per cycle time. In comparison, the conventional vacuum ejector requires 5.11 seconds per cycle. Calculated over for 245 workdays per year, with 3,840 handling cycles per day and two operating shifts, the user can save around 11,000 m³ of compressed air. This translates to around 65 % less compressed air compared to a conventional vacuum ejector. When developing new products, Schmalz focuses on advancing technology as well as developing resource-efficient solutions. The user benefits from the long service life of the products, reduces energy consumption and lowers operating costs. In addition, the user is helping to protect the environment.
