Norway hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder

(Norway stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stroke adjustable cylinder are widely used in Norway，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed stroke adjustable cylinder for customers from Norway.

Introduction to stroke adjustable cylinder:

stroke adjustable cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the stroke adjustable cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The stroke adjustable cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the stroke adjustable cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the stroke adjustable cylinder wall due to the stiffness and the weight of the parts, causing scars.

Protection of the stroke adjustable cylinder surface: During the dismantling process, safety protection should be carried out on the stroke adjustable cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the stroke adjustable cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the stroke adjustable cylinder should be cleaned up in time.

When the stroke adjustable cylinder needs to be stored for a period of time, please follow the recommended methods: The stroke adjustable cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stroke adjustable 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 stroke adjustable cylinder should not be in direct contact with water vapor for a long time. The stroke adjustable cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stroke adjustable 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 stroke adjustable cylinder Before working, the stroke adjustable cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stroke adjustable 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 stroke adjustable cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
