Finland hydraulic cylinder,roller press hydraulic cylinder manufacturer,roller press hydraulic cylinder
(Finland roller press hydraulic cylinder,produced by Hebei Hengyu company）
roller press hydraulic cylinder are widely used in Finland，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed roller press hydraulic cylinder for customers from Finland.
The repair method of roller press hydraulic cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.
The roller press hydraulic cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the roller press hydraulic cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the roller press hydraulic cylinder wall due to the stiffness and the weight of the parts, causing scars.
The roller press hydraulic 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.
We can not just consider the price and ignore the quality when we purchase the roller press hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the roller press hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the roller press hydraulic cylinder is not required.
What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.
How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.
