(Ecuador stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to stainless steel cylinder:

Before the stainless steel cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

When the stainless steel cylinder is installed, the piston and the stainless steel cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the stainless steel cylinder head boss is easy to cause scars when it hits the inner surface of the stainless steel cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized stainless steel cylinders, only careful and careful operation can be avoided.

stainless steel 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.

Causes and countermeasures of oil stainless steel cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stainless steel cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stainless steel cylinder is visibly scarred, the stainless steel cylinder must be replaced. It can be pressurized at one end of the stainless steel cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stainless steel cylinder piston drift may not come from the stainless steel cylinder, the above method to determine the stainless steel cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Answers to some questions about stainless steel 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.

What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
