Structural Features
A. The tensioning cylinder and the return cylinder are double-sealed, which improves the sealing reliability. Key connections are used between the small cylinder and the second cylinder, the small cylinder and the rear end cover, and the small cylinder and the tool ring to prevent rotation. Both are sealed with a Gray ring or Sterling ring, and the seal is reliable.
B. The second cylinder and the piston head are designed in an integral form, which avoids the possibility of failure due to the welding of the two bodies or the connection of the two bodies with threads. Increased processing technology difficulty, but improved reliability.
C. The improved design of the wear-resistant ring and wear-resistant sleeve avoids the possibility of the assembled type coming out under force and improves product reliability.
D. All important stress-bearing parts are made of high-quality alloy structures or tool steel to improve hardness and strength.
Instructions for using
1. The jack is connected to the oil pump through a high-pressure oil pipe, and a professional electrician connects the oil pump to the power supply through a power cord.
2. Turn on the oil pump and run it for no less than 3 minutes.
3. The jack piston reciprocates no less than 3 times. If there is crawling, it can be increased to 6 times. If there is still crawling, stop the pump for inspection and analyze the reason.
4. When the jack and the oil pump system are calibrated and before tensioning, the jack must be run dry. Calibration and tension work can only be started after everything is normal.
