(Saudi Arabia 500 tons hydraulic press cylinder,produced by Hengyu Hydraulic Cylinder Factory）

500 tons hydraulic press cylinder are widely used in Saudi Arabia，because of long service life，smooth movement，high work efficiency.So our company has designed 500 tons hydraulic press cylinder for customers from Saudi Arabia.

Introduction to 500 tons hydraulic press cylinder:

What kind of process is used in the 500 tons hydraulic press cylinder to make high-quality 500 tons hydraulic press cylinder products: the body is the main component of the 500 tons hydraulic press cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The 500 tons hydraulic press cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the 500 tons hydraulic press cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the 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 RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the 500 tons hydraulic press cylinder increases by 25%. If the service life of the 500 tons hydraulic press cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. 500 tons hydraulic press cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the 500 tons hydraulic press cylinder is prone to misoperation or operation 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. (2) The piston rod and 500 tons hydraulic press cylinder are stuck or the 500 tons hydraulic press cylinder is blocked. At this time, no matter how to manipulate, the 500 tons hydraulic press cylinder does not move or moves very little. 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 500 tons hydraulic press cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The difference between the integral 500 tons hydraulic press cylinder and the split 500 tons hydraulic press cylinder: The integral 500 tons hydraulic press cylinder and the split 500 tons hydraulic press cylinder in the 500 tons hydraulic press cylinder are two different 500 tons hydraulic press cylinders, and they are very different. The whole 500 tons hydraulic press cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split 500 tons hydraulic press cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and 500 tons hydraulic press cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

500 tons hydraulic press cylinder can not drive the load troubleshooting: oil pressure is too low. 500 tons hydraulic press cylinder selection specifications are too small. Leakage in 500 tons hydraulic press cylinder or associated hydraulic system element.

When the 500 tons hydraulic press cylinder is installed, the piston and the 500 tons hydraulic press 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 500 tons hydraulic press cylinder head boss is easy to cause scars when it hits the inner surface of the 500 tons hydraulic press 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 500 tons hydraulic press cylinders, only careful and careful operation can be avoided.

Answers to some questions about 500 tons hydraulic press cylinder:

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
