The structure of double acting hydraulic cylinder earring rod HSGS series can be used for the work of a single rod with a double action in a plane. The cylinder, cylinder head and the end cover form a sealed cavity of double acting hydraulic cylinder earring rod, which is used to seal the hydraulic oil. When the pressure oil from the right end of the oil port into hydraulic cylinder, in living plug on the right end surface of the force generated, pushes the piston and piston rod moves to the left, forming a thrust; if from the port of the left end of the oil into the oil pressure, the piston moves to the right, the piston rod is retracted, the formation of tension. The double acting hydraulic cylinder earring rod HSGS series installed on the fixed position of the machinery, earrings and a load mechanism is connected, the piston rod extending and retracting can push or pull load to do reciprocating motion and hydraulic energy into mechanical energy. Left end of the piston rod by screw threads and earrings and connected with the fastening screw; and the right end of the piston bore fit, to key card and card fixing cap. The outer circle of the piston rod and the piston is provided with a O type sealing ring, which plays the role of radial and fixed seal to prevent leakage of oil between the clearance. The cushion plunger is often combined with the piston rod to ensure the same ring.
Some piston holes into step shaped, small hole and is matched with the piston rod; when the piston to the left is moved to the left end of the trip, the supporting seat of the small circle to insert the piston hole formed in the buffer, buffer role. The supporting seat is equipped with the left end of the cylinder body, the outer circle and the left end face is provided with O-sealing ring, inner hole is provided with a guide sleeve, play the guiding role. The end cover is fixed on the end face of the cylinder body, and a gap between the inner hole and the piston rod is provided with a YX type sealing ring and a dust ring. The head and the cylinder body of double acting hydraulic cylinder earring rod HSGS series are welded, and the inner hole of the cylinder head is a buffer hole and is communicated with the oil port. The bottom and the earrings can be made one, reduce the number of spare parts and easy processing. The two exhaust valves are respectively arranged at the two ends of the hydraulic oil cylinder, which is convenient to remove the air in the hydraulic cylinder.
1. With ▲ is ratio = 2 of connection size.
2. with ※ is the ratio of 1.7.
