Denmark double rod cylinder

(Denmark double rod cylinder,produced by Hengyu Hydraulic Co., Ltd)

double rod cylinder are widely used in Denmark,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed double rod cylinder for customers from Denmark.

Introduction to double rod cylinder:

double rod cylinder and hydraulic station selection: Select the type and structure of the double rod cylinder according to the operation requirements of the main engine. According to the external load force borne by the double rod cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the double rod cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the double rod cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the double rod cylinder, the diameter of the piston and the piston rod.

The viscosity of the working oil used in the double rod 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.

In the process of using the double rod cylinder, sometimes such a problem will occur, the double rod cylinder can not act immediately after the instruction of the double rod 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 double rod 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.

The meaning of the double rod cylinder model marked by the double rod cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the double rod cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the double rod cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about double rod cylinder:

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
