(Singapore steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steel mill cylinder are widely used in Singapore，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed steel mill cylinder for customers from Singapore.

Introduction to steel mill cylinder:

When installing the steel mill cylinder, the axial ends of the steel mill cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the steel mill cylinder, there is axial expansion. If the two ends of the steel mill cylinder are fixed, all parts of the steel mill cylinder will be deformed. When disassembling the steel mill cylinder, it is strictly forbidden to hammer the steel mill cylinder and the piston surface, such as the steel mill cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The coordination of the sliding parts of the steel mill cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the steel mill cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Answers to some questions about steel mill cylinder:

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.

What hydraulic oil does servo cylinder generally use?
The medium used by the cylinder generally depends on the working condition of the use, including pressure, installation environment, sealing material, etc. I think the first thing to consider is the impact of the sealing material. Mineral oil is a good choice if it is not too fire-resistant or used in a high temperature environment. 1, servo cylinder features: closed-loop servo control, control accuracy of 0.01mm; Precise control of thrust, increase pressure sensor, control accuracy up to 1%; It is easy to connect with PLC and other control systems to achieve high precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. 2, the servo cylinder can be fault-free in harsh environments, and the protection level can reach IP66.
