(Portugal rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Portugal，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed rolling mill cylinder for customers from Portugal.

Introduction to rolling mill cylinder:

rolling mill cylinder installation precautions: Before installing the rolling mill cylinder into the system, the parameters on the rolling mill cylinder label should be compared with the parameters when ordering. The base of the rolling mill cylinder must have sufficient stiffness, otherwise the rolling mill cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular rolling mill cylinder action. Troubleshooting method: Replace the rubber hose.

The commonly used buffer structure of the rolling mill cylinder is composed of a piston boss and a rolling mill cylinder head groove. When the piston moves close to the rolling mill cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

When the long-stroke rolling mill cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in rolling mill cylinder head seal damage, oil leakage, and piston sleep in the rolling mill cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the rolling mill cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about rolling mill cylinder:

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.

Where is the cylinder used? What is it used for? Can it be used in cars?
Cylinders can be used as actuator in hydraulic system. Such as hydraulic jacks, dump truck box lifting device, dodging (snow) machine loader bucket lifting device. Hydraulic cylinders are also widely used in car cranes. It's all about cars.
