(Congo steel mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

steel mill cylinder are widely used in Congo，because of long service life，smooth movement，high work efficiency.So our company has designed steel mill cylinder for customers from Congo.

Introduction to steel mill cylinder:

The coordination of the sliding parts of the steel mill cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

In the process of using the steel mill cylinder, sometimes such a problem will occur, the steel mill cylinder can not act immediately after the instruction of the steel mill cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil steel mill cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

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

In order to ensure the service life of the steel mill cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the steel mill cylinder, causing damage to the seal and causing leakage in the steel mill cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about steel mill cylinder:

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.
