The working principle of the membrane press machine(1)

The membrane press machine is mainly composed of crankcase, crankshaft, main and auxiliary connecting rods, and a first cylinder and a two stage cylinder arranged according to the V type. Each cylinder comprises a cylinder head, an oil distribution tray and a cylinder body. (membrane press machine)Each cylinder has a surface with the same coordinates as the oil distribution tray, and the diaphragm is sandwiched between the cylinders. An intake and exhaust valve is arranged on the cylinder head, and holes are arranged on the oil distribution tray. Connect the space under the diaphragm with the oil cylinder. The piston of the primary oil cylinder is connected with the main connecting rod, the piston of the secondary oil cylinder is floating connected with the crosshead, and the crosshead is connected with the auxiliary connecting rod. When the crankshaft rotates, the piston in the oil cylinder moves back and forth to push the oil, Periodically changes the oil pressure in the oil cylinder. (membrane press machine)The diaphragm produces elastic vibration under the action of the pressure difference between oil pressure and gas and its own elastic deformation force, and periodically changes the volume of the gas compression chamber (cylinder) to compress the gas. When the cylinder piston circulates back and forth once, the diaphragm vibrates once. Under the control of the inlet and exhaust valve, it completes the cycle process of suction, compression, exhaust and expansion.
