Sudan hydraulic cylinder,push plate cylinder manufacturer,push plate cylinder

(Sudan push plate cylinder,produced by Hengyu Group）

push plate cylinder are widely used in Sudan，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed push plate cylinder for customers from Sudan.

Introduction to push plate cylinder:

When the push plate cylinder needs to be stored for a period of time, please follow the recommended methods: The push plate cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the push plate cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil push plate cylinder should not be in direct contact with water vapor for a long time. The push plate cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the push plate cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the push plate cylinder Before working, the push plate cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the push plate cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

push plate cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

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

When the push plate cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about push plate cylinder:

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.

What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.
