Dominica hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder

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

steel mill cylinder are widely used in Dominica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed steel mill cylinder for customers from Dominica.

Introduction to steel mill cylinder:

The steel mill cylinder is not the same as the steel mill cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the steel mill cylinder can not be used as a high-power power component, but the steel mill cylinder can be used as a relatively large power component, or the steel mill cylinder system can be used.

The quality of the steel mill cylinder can not be ignored in the purchase of the steel mill cylinder. The steel mill cylinder is the main component of the steel mill cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. steel mill cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of steel mill cylinder is deep hole processing, which has always troubled the processing personnel.

In order to ensure the service life of the steel mill cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

How to determine the working pressure of the steel mill cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, steel mill cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Answers to some questions about steel mill cylinder:

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 remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
