(Congo plating press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to plating press hydraulic cylinder:

plating press hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching plating press hydraulic cylinder block - fine boring plating press hydraulic cylinder block - grinding plating press hydraulic cylinder block. The rolling method is: broaching plating press hydraulic cylinder block - fine boring plating press hydraulic cylinder block - rolling plating press hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the plating press hydraulic cylinder block is about 1-2 days, rolling 1 meter of the plating press hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the plating press hydraulic cylinder increases by 25%. If the plating press hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality plating press hydraulic cylinders, you must take the rolling production process. After the plating press hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular plating press hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

After the plating press hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

The piston seal of the plating press hydraulic cylinder is the main element to prevent leakage in the plating press hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about plating press hydraulic cylinder:

How big is the 100t cylinder pump and how big is the motor?
Load is calculated at 15 tons, stroke is calculated at 100 (both take the maximum) 15 tons = 15,000 kg, 15,000/210 bar (21 mpa) =71.42 square centimeters (cylinder area) 71.42/3,14 In the root *2=90,5 the inner diameter of the cylinder can be taken 100 mm. Travel 100 cm, that is, one meter, assuming 10, seconds a back and forth, then it is six times a minute, six meters per minute, then the required flow is,71,42*600 cm (6 meters) =42840 mm =42.84 liters/minute 42.84*21/60=14.9 kilowatts can choose 1450 RPM 4-stage motor 15KW.

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.
