Feature of automatic stressing jack:
1. more compact structure
2. good sealing performance
3. lightweight
4. small volume
5.convenient installation and dismantlement.
Application:
bridges, high buildings, coal mines, railway and subway, water conservancy, and hydropower engineering.
Working principle:
The oil cylinder, heading cover(adjusting nut), end cover(hold-down ring), front sealing plate, a back sealing plate of this jack connect with a cross-core socket to form a "motionless body", and the piston of the jack is "motion body" when the hydraulic oil pushes the "motion body" to the right, it begins to tension; When the hydraulic oil pushes the motion body to the left, it is the piston-return after the tension.
Use hydraulic oil for 65°C, kinematic viscosity for 15~ 50 mm2/s, the diameter of the impurity is not more than 137 μ m, and high-quality mineral oil with certain rust resistance, recommend 32 # hydraulic oil in winter, 46 # hydraulic oil in summer, when it is used in a special environment, please consider to use other types of oil.
