The invention provides a pneumatically-controlled constant-temperature and constant-pressure oil tank. The pneumatically-controlled constant-temperature and constant-pressure oil tank comprises an oil tank body and a control box installed on the oil tank body. A piston is arranged in the oil tank body, a sealing ring and a baffle ring are arranged on the piston, an oil return opening and an oil suction opening are formed in the bottom of the oil tank body, one-way valves are arranged on the oil return opening and the oil suction opening, and a pressure sensor and a temperature sensor are arranged on the oil suction opening. A temperature changer slot is formed outside the oil tank main body; heating sheets and cooling sheets are alternately mounted in the temperature changer slot; a control panel and an air pump are arranged in the control box, and an outlet of the air pump is connected with an inlet of the pneumatic proportional valve. The size is small, the occupied area is small, the number of additional structures is small, the overall installation cost is low, use is convenient, and extra cost cannot be increased; and constant-temperature and constant-pressure regulation and control can be conducted on oil in the oil tank without an external control assembly, and therefore the application range of the oil tank can be greatly widened.

    本发明提供一种气动控制的恒温恒压油箱,其包括油箱主体和安装在油箱主体上的控制箱;油箱主体中设有活塞,活塞上设有密封圈和挡环,油箱主体底部开有回油口和吸油口,回油口和吸油口上均设有单向阀,吸油口上设有压力传感器和温度传感器;油箱主体外部设有变温器插槽;变温器插槽中交替安装有加热片与冷却片;控制箱中设有控制板和气泵,气泵的出口与气动比例阀的入口相连。其体积小、占地面积小且附加结构少,整体安装成本较低,使用方便,不会增加额外的成本;并且能够对油箱内部的油液进行恒温恒压的调控,不需要外部控制组件即可实现,从而能够大幅度增加油箱的使用范围。
