(Switzerland baling press cylinder,produced by Hengyu Hydraulic Co., Ltd）

baling press cylinder are widely used in Switzerland，because of no need for deceleration device，long service life，smooth movement.So our company has designed baling press cylinder for customers from Switzerland.

Introduction to baling press cylinder:

The piston seal of the baling press cylinder is the main element to prevent leakage in the baling press 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.

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

baling press cylinder is the most important part of construction machinery, the traditional processing method is: broaching baling press cylinder block - fine boring baling press cylinder block - grinding baling press cylinder block. The rolling method is: broaching baling press cylinder block - fine boring baling press cylinder block - rolling baling press cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the baling press cylinder block is about 1-2 days, rolling 1 meter of the baling press 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 baling press cylinder increases by 25%. If the baling press 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 baling press cylinders, you must take the rolling production process. After the baling press 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.

How the cavitation of the baling press cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the baling press cylinder, resulting in corrosive damage to the parts.

Answers to some questions about baling press cylinder:

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.

Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
