Bahrain hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder

(Bahrain steel mill cylinder,produced by Hebei Hengyu company）

steel mill cylinder are widely used in Bahrain，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed steel mill cylinder for customers from Bahrain.

Introduction to steel mill cylinder:

Before purchasing the steel mill cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

The meaning of the steel mill cylinder model marked by the steel mill cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the steel mill cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the steel mill cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The steel mill cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

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

Answers to some questions about steel mill cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
