Engineering oil cylinder

Advantages of using hydraulic cylinder of engineering vehicle

The hydraulic cylinder of the engineering vehicle comprises a cylinder barrel, a cylinder tail, a guide sleeve, a piston and a piston rod. The cylinder tail and guide sleeve are respectively arranged at both ends of the cylinder barrel, and the cylinder tail and guide sleeve are respectively connected with the cylinder barrel through screws. Oil holes are respectively arranged on the cylinder tail and cylinder barrel.

The cylinder wall of the cylinder barrel is embedded with a heat pipe, which is made of copper. The left end of the heat pipe passes through the cylinder tail and is connected with a radiator, which is equipped with a radiator. The hydraulic cylinder barrel of the engineering vehicle is equipped with a piston sliding, a piston seal ring is set between the piston and the inner wall of the cylinder barrel, a threaded hole is set in the piston, the piston rod is fixed on the piston through the threaded hole, and an O-ring is set between the piston rod and the piston.

The right end of the piston rod passes through the guide sleeve. An ear ring is fixed on the right end of the piston rod. A seal ring is set between the piston rod and the guide sleeve. A dust ring is fixed at the beginning of the right end of the guide sleeve, and the piston rod passes through the dust ring. A mounting channel is arranged in the piston rod. The heat sink is set with 10-15 heat sinks, which are made of aluminum, and the distance between the heat sinks is 5-1mm. The width of the piston seal ring is 3-5 mm. The diameter of the installation passage is 1/3-1/2 of the diameter of the piston rod.

The utility model is provided with a heat pipe in the cylinder wall. The heat pipe transfers the heat generated on the hydraulic cylinder barrel of the engineering vehicle to the radiator, which emits the heat, reduces the temperature of the cylinder, reduces the heat accumulation, protects the components of the cylinder, improves the safety of the hydraulic cylinder, and extends the service life of the hydraulic cylinder of the engineering vehicle.
