(Indonesia fig support cylinder,produced by Hengyu Hydraulic Co., Ltd）

fig support cylinder are widely used in Indonesia，because of long service life，smooth movement，high work efficiency.So our company has designed fig support cylinder for customers from Indonesia.

Introduction to fig support cylinder:

There are some honeycomb holes in the inner wall of the fig support cylinder, piston or piston rod surface. How is this formed? When we repair the fig support cylinder, we can see that there are some honeycomb holes on the inner wall of the fig support cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the fig support cylinder is targeted to prevent. Is very necessary.

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

Protection of the fig support cylinder surface: During the dismantling process, safety protection should be carried out on the fig support cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the fig support cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the fig support cylinder should be cleaned up in time.

When the fig support cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the fig support cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the fig support cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the fig support cylinder can meet the requirements by grinding. However, the life and reliability of this repair fig support cylinder are not high.

Answers to some questions about fig support cylinder:

What causes hydraulic cylinder oil leakage?
1. Internal leakage (1) The wear ring on the piston is seriously worn, leading to friction between the piston and the cylinder liner, and finally strain the cylinder liner, piston and seal; 2) Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging; 3) The hydraulic oil is dirty, and a large number of impurities enter the cylinder and wear the piston seal to bad; 2. External leakage 1) cylinder inlet and outlet tubing joint cracking; (This I see in the actual work is still more) 2) The piston rod extension end with the piston rod seal damage, mostly due to the piston cylinder is caused by hair, but also caused by aging; 3) The seal between the extended end of the piston rod and the liner is damaged.

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.
