(Chile large tonnage cylinder,produced by Hebei Hengyu company）

large tonnage cylinder are widely used in Chile，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed large tonnage cylinder for customers from Chile.

Introduction to large tonnage cylinder:

large tonnage cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the large tonnage cylinder is placed for a period of time, the large tonnage cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The daily inspection of the large tonnage cylinder includes: checking the connection of the large tonnage cylinder and the pipe joint for leaks. Check the large tonnage cylinder rod for leaks. Check the large tonnage cylinder connection for leaks. When the large tonnage cylinder moves, the work is normal and smooth. Whether the large tonnage cylinder has internal leakage.

In the process of using the large tonnage cylinder, sometimes such a problem will occur, the large tonnage cylinder can not act immediately after the instruction of the large tonnage cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil large tonnage cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Factors that should be considered when selecting the oil seal in the large tonnage cylinder: some specific factors should be taken into account when selecting the oil seal in the large tonnage cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: large tonnage cylinder diameter, piston rod diameter, piston rod and piston groove size, large tonnage cylinder working pressure, large tonnage cylinder movement speed, hydraulic system oil temperature and large tonnage cylinder working environment.

Answers to some questions about large tonnage cylinder:

What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are usually made of 45# steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 45# seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the rod surface needs to be chrome plated.

What adhesive should be used when the cylinder is cracked?
There is a kind of cast iron glue, industrial products market can buy, A, B formula, that is, a tube is A, a tube is B, when used proportionally prepared, check the instructions. Polish the glue after it dries, and then grind it again.
