(Turkmenistan extra long cylinder,produced by Hengyu Group）

extra long cylinder are widely used in Turkmenistan，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed extra long cylinder for customers from Turkmenistan.

Introduction to extra long cylinder:

The internal leakage of the extra long cylinder is an important indicator to measure the quality of the extra long cylinder: the internal leakage of the extra long cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the extra long cylinder, so that the extra long cylinder can not accurately and stably stop in a certain position of the extra long cylinder, so it is one of the main indicators of the extra long cylinder.

Disassembly extra long cylinder: When disassembly extra long cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the extra long cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the extra long cylinder.

The extra long cylinder should be used correctly and maintained regularly. The extra long cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the extra long cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

extra long cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the extra long cylinder head itself is the guide sleeve of the piston rod, the extra long cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the extra long cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Answers to some questions about extra long cylinder:

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
