It is often used to convert the output signal of pneumatic regulating instrument or pneumatic manual operator into hydraulic signal to drive the action of hydraulic actuators.Hydraulic actuators are characterized by high power, good mechanical rigidity and fast dynamic response, so they are widely used in precision control systems, heavy-duty machine tools, automobiles, ships and aviation.And pneumatic instrument for a variety of environments have a strong adaptability, and easy maintenance, maintenance, low system investment cost, so in the above applications are often used pneumatic instrument and hydraulic actuators combined with the automatic control system, then it is necessary to use the gas-liquid converter.The commonly used gas-liquid converter is integrated with hydraulic actuators. Gas and liquid is converter converts air pressure, oil pressure (pressure ratio 1:1) components, can be used as auxiliary parts group into the gas and liquid loops. Using it can eliminate the general pneumatic circuit in slow motion when crawling and unstable phenomenon, and can be used and all kinds of pneumatic components. Characteristics 1. Specifications, strong adaptability. Such as Japan da ke company produces the gas-liquid converter has 48 kinds of specifications, the effective volume of the output pressure oil to 40 ~ 27000 cm ~ 3, common work pressure is 0.3 ~ 0.7 MPa, just adjust the pneumatic pressure reducing valve, can get the corresponding hydraulic change. Reaction speed, can satisfy different customers' requirements.Because the oil temperature is stable, the air will not be mixed into the shanshan, high efficiency, thus can obtain the stable movement.3. Compared with the hydraulic, no complex, large pump.
