Yuan xing company engaged in the field of mine machinery hydraulic cylinder has a history of more than 10 years, has a wealth of experience and advanced technology, development of shield machine, mining truck, drill, crane and other mine machinery hydraulic oil cylinder. Yuan xing company is skilled in mining machinery hydraulic cylinder buffer system, sealing system, corrosion prevention and other technologies. In the mine machinery oil cylinder industry, yuan xing company has a remarkable achievement. Mine machinery hydraulic cylinder used for a long time, the hydraulic oil cylinder of the hydraulic system control of the low pressure condition, sometimes may cause failure or mistake, these are the more common phenomenon, although the end result is the same, but it is not the same reason. Common causes of this phenomenon include: Generally, this situation is because the throttling resistance in the control pipeline is too large, the regulation of the flow valve is not very correct, the control pressure is not appropriate, and the pressure source in the same inlet is also disturbed. This is the time to check the control pressure source to ensure that the pressure must be adjusted to the system's specified value. If the flow valve or direction valve core is stuck or the valve hole is blocked, the hydraulic cylinder is more likely to misoperate or malfunction at this time. If such a situation occurs, the oil should be promptly inspected for contamination; Check to see if there is something dirty or colloidal sediment sticking in the valve core causing the valve hole to be blocked. Also check how worn the valve body is. Product Process: 1. Raw materials entering the factory, 27SiMn, 40CrMo, ST52, 45# steel tubes or bars for choice 2. Do the pre-treatment including pickling, phosphating and saponification, and then cold-draw the seamless steel tubes. 3. Put the steel tubes into the tempering furnace to do the stress relief annealing in convenience of the subsequent the processing. 4. Multi-roll straightening machine, with 10 straightening points, achieves the automatic rolling straight improving the efficiency greatly 5. Heat treatment to obtain work pieces with different properties by changing their internal microstructure or surface chemical composition. 6. Cylindrical degree can be controlled within 0.03mm and the surface roughness is up to 0.4 by honing with range:φ40mm-φ450mm and longest length: 12000mm 7. Machining processes to obtain high precision parts with complex shapes strictly according to the detailed drawings. 8. Electroplating production process fulfills the functional and ornamental requirements for coating work pieces of different dimensions according to specific application requirements. 9. Cleaning all the parts by automatic cleaning machine in the special solution and under special temperature control effectively. 10. All the parts are assembled into complete cylinders according to the strict assembly instructions by skillful workers in dust-free workshop. 11. Do proof pressure and performance tests to check whether the cylinders can operate smoothly and stably under the specified pressure with no leakage and deformation. 12. Do the painting including high quality primer and topcoat to obtain beautiful appearance and protect the cylinders against the anticorrosion. 13. Wooden pallet or boxes packing with plastic films wrapped on the surface, suitable for long-time sea transport. Product Advantages： 1. Easy to operate, easy to maintain 2. Reliable work, high efficiency 3. Solid structure, handsome in appearance Application: Large and medium-sized mining, metallurgy, forging, casting, engineering transportation, hydraulic machinery, food processing machinery, machine tools, civil engineering, construction machinery, chemical machinery, medical machinery, injection molding machinery, automated assembly line, Light industry machinery industry.
