(Estonia 500 tons hydraulic press cylinder,produced by Hebei Hengyu company）

500 tons hydraulic press cylinder are widely used in Estonia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed 500 tons hydraulic press cylinder for customers from Estonia.

Introduction to 500 tons hydraulic press cylinder:

The viscosity of the working oil used in the 500 tons hydraulic press cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

When the 500 tons hydraulic press cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the 500 tons hydraulic press cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the 500 tons hydraulic press cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the 500 tons hydraulic press cylinder can meet the requirements by grinding. However, the life and reliability of this repair 500 tons hydraulic press cylinder are not high.

Do not regularly check the damage of the chrome layer of the 500 tons hydraulic press cylinder: completely extend the 500 tons hydraulic press cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the 500 tons hydraulic press cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the 500 tons hydraulic press cylinder seal. Welding slag is strictly prohibited on the surface of the 500 tons hydraulic press cylinder.

When the 500 tons hydraulic press cylinder needs to be stored for a period of time, please follow the recommended methods: The 500 tons hydraulic press cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the 500 tons hydraulic press cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil 500 tons hydraulic press cylinder should not be in direct contact with water vapor for a long time. The 500 tons hydraulic press cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the 500 tons hydraulic press cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the 500 tons hydraulic press cylinder Before working, the 500 tons hydraulic press cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the 500 tons hydraulic press cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about 500 tons hydraulic press cylinder:

How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.

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.
