The invention discloses an oil tank pressure maintaining deformation control device and a control method, and belongs to the technical field of forklift oil tank detecting tools. The oil tank pressuremaintaining deformation control device comprises a fixed cantilever and an air cylinder arranged at one end of the fixed cantilever, a piston rod of the air cylinder penetrates through the fixed cantilever to be connected with a pressing plate, the fixed cantilever is further provided with a pressure control valve, the pressure control valve is connected with an air opening of the air cylinder through a first air guide pipe and a second air guide pipe, and the pressure control valve is also connected with an air pipe. The oil tank pressure maintaining deformation control device is simple in structure, convenient to use and strong in practicability. The air cylinder is used as a driving mechanism, when oil tank gas tightness detection is carried out, reverse pressure is applied to the deformation position, and it is ensured that the oil tank is not deformed; and reverse pressure is applied through the air cylinder, control over the balance of internal and external action force of the oil tank is facilitated, and the oil tank pressure maintaining deformation control device and the control method are suitable for popularization.
Description
technical field [0001] The invention relates to the technical field of forklift fuel tank detection tools, in particular to a pressure-holding deformation control device and control method for a fuel tank. Background technique [0002] Forklift fuel tanks can be divided into open fuel tanks and closed fuel tanks according to whether the liquid level in the fuel tank is connected to the atmosphere, and can be divided into integral type and separate type according to whether it is integrated with the whole machine. Conventional forklifts choose open fuel tanks, and the structure is as follows image 3 As shown, it is generally welded by steel plates, and its shape is determined according to the overall structure of the frame. In addition to the main function of storing diesel and hydraulic oil, the forklift fuel tank also plays the role of heat dissipation, escape of air mixed in the oil, and precipitation of pollutants in the oil, so the structure of the fuel tank should meet...
