(Portugal 200 ton hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

200 ton hydraulic cylinder are widely used in Portugal，because of no need for deceleration device，long service life，smooth movement.So our company has designed 200 ton hydraulic cylinder for customers from Portugal.

Introduction to 200 ton hydraulic cylinder:

The method of sleeve 200 ton hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the 200 ton hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the 200 ton hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

When the 200 ton hydraulic cylinder is installed, the piston and the 200 ton hydraulic 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 200 ton hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the 200 ton hydraulic 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 200 ton hydraulic cylinders, only careful and careful operation can be avoided.

The viscosity of the working oil used in the 200 ton hydraulic 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.

If the piston rod and 200 ton hydraulic cylinder are stuck or the 200 ton hydraulic cylinder is blocked, at this time, no matter how to operate, the 200 ton hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the 200 ton hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about 200 ton hydraulic cylinder:

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.

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
