The air-liquid converter is a component that converts air pressure into oil pressure (boost ratio 1:1), and can be used as an accessory to be integrated into the gas-liquid circuit. Using it can eliminate the crawling and instability in low-speed motion in general pneumatic circuits, and can be used in combination with various pneumatic components.
The converter is a vertical oil cylinder with the oil surface in a static pressure state. When compressed air acts directly on the oil surface, it will not cause oil surface fluctuations and oil splashes.
The converter is filled with hydraulic oil. Since there is no piston in the middle of the converter, the oil is in the lower part of the oil cylinder. Switch the solenoid valve, the compressed air enters the upper part of the gas-liquid converter, the hydraulic oil enters the cylinder through the one-way throttle valve to push the piston rod forward, and the one-way throttle valve realizes stepless speed change without creeping; before switching the two-position four-way solenoid valve Push the piston rod to reset, the hydraulic oil quickly returns to the gas-liquid converter through the throttle valve. Due to the effect of the baffle, the hydraulic oil will not enter the upper pipeline. When the two-position four-way solenoid valve returns to the position, a new working cycle is started.
The key problem of the converter is to avoid the gas being mixed into the oil and being output, causing the instability of the transmission. Generally, a buffer device is installed at the air inlet to prevent the input compressed air from blowing directly on the liquid surface, causing liquid level fluctuations and oil splashing. Keep a certain distance between the buffer and the liquid level.
Converters are widely used in important precision control systems such as automation circuits, manipulators, heavy-duty machine tools, spot welders, conveyor belts, medical equipment, automobiles, ships, and aviation.
