How much is the hydraulic cylinder? What are the repair techniques of hydraulic cylinders?

The hydraulic cylinder is an actuator in the hydraulic transmission system. It is an energy conversion device that can convert hydraulic energy into mechanical energy. The hydraulic motor does continuous slewing motion, while the hydraulic cylinder does reciprocating motion. The structure of the hydraulic cylinder is divided into three categories: piston cylinder, plunger cylinder and swing cylinder. The piston cylinder and the plunger cylinder are reciprocating linear motions, output speed and thrust, and the swing cylinder is reciprocating swing, output angular velocity (speed) and torque . Do you know how much hydraulic cylinders are on the market?

　　 Repair technology of hydraulic cylinder

1. Roast the scratched parts with oxygen-acetylene flame (control the temperature and avoid surface annealing), roast the oil on the metal surface perennially, until there is no sparking.

2. Treat the scratched surface with an angle grinder to a depth of more than 1 mm, and grind a groove along the guide rail, preferably a dovetail groove. Drill holes at both ends of the scratch to deepen and change the force.

3. Clean the surface with absorbent cotton dipped in acetone or absolute ethanol.

4. The metal repair material is applied to the scratched surface; the first layer should be thin, evenly and completely cover the scratched surface to ensure the best adhesion of the material to the metal surface, and then apply the material to the entire repair site and press repeatedly, Make sure the material is filled and reaches the required thickness so that it is slightly higher than the surface of the guide rail.

5. It takes 24 hours for the material to fully achieve various properties at 24 ℃. In order to save time, the temperature can be increased by halogen tungsten lamps. When the temperature is increased by 11 ℃, the curing time will be shortened by half. The optimal curing temperature is 70 ℃.

6. After the material is cured, use a fine grinding stone or scraper to repair the material above the surface of the guide rail, and the construction is completed.

The above is the information introduced to friends about how much the hydraulic cylinder is and the repair process of the hydraulic cylinder. There are many applications of hydraulic cylinders in the machinery industry, so in the process of use, we must also pay attention to the fault diagnosis and maintenance of the hydraulic cylinder, so that the hydraulic cylinder is always kept in a good state to have a more efficient work.
