(Burma press machine hydraulic cylinder,produced by Hebei Hengyu company）

press machine hydraulic cylinder are widely used in Burma，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed press machine hydraulic cylinder for customers from Burma.

Introduction to press machine hydraulic cylinder:

Under normal circumstances, the press machine hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the press machine hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the press machine hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the press machine hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the press machine hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

press machine hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching press machine hydraulic cylinder block - fine boring press machine hydraulic cylinder block - grinding press machine hydraulic cylinder block. The rolling method is: broaching press machine hydraulic cylinder block - fine boring press machine hydraulic cylinder block - rolling press machine hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the press machine hydraulic cylinder block is about 1-2 days, rolling 1 meter of the press machine 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 press machine hydraulic cylinder increases by 25%. If the press machine 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 press machine hydraulic cylinders, you must take the rolling production process. After the press machine 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 order to ensure the service life of the press machine hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the press machine hydraulic cylinder, causing damage to the seal and causing leakage in the press machine hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

The material of the sliding part of the press machine hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Answers to some questions about press machine hydraulic cylinder:

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.
