Greece hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Greece stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stroke adjustable cylinder are widely used in Greece,because of excellent fatigue and impact resistance,smooth movement,high work efficiency.So our company has designed stroke adjustable cylinder for customers from Greece.
Do not regularly check the damage of the chrome layer of the stroke adjustable cylinder: completely extend the stroke adjustable cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the stroke adjustable cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the stroke adjustable cylinder seal. Welding slag is strictly prohibited on the surface of the stroke adjustable cylinder.
stroke adjustable cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.
The stroke adjustable cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the stroke adjustable cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The stroke adjustable cylinder is basically composed of stroke adjustable cylinder and stroke adjustable cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
stroke adjustable cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
