Digital Control Hydraulic Variable Pump Based on Mechatronic-Hydraulic-Air Integration Driven by Compressed Air

Abstract:

This paper introduces digital control hydraulic variable pump based on mechatronic-hydraulic- air integration driven by compressed air. By inserting the toggle force amplifier in between double-acting rodless air cylinder and variable pump, this pump, driven by compressed air, utilizes small forced air to create big output power. The displacement of air cylinder piston is measured by using digitally linear displacement sensor and it is compared with input signal by computer in order to control pressure and flow rate output by hydraulic cylinder. This pump provides high flexibility and high reliability, simple structure and compact; it is easier to control by artificial intelligence and it will be widely used in the industry.
