(Tunisia unidirectional cylinder,produced by Hengyu Group）

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

Introduction to unidirectional cylinder:

When using the unidirectional cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the unidirectional cylinder block. If the unidirectional cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the unidirectional cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the unidirectional cylinder, so that the working efficiency of the unidirectional cylinder is reduced.

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

When the unidirectional cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the unidirectional cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the unidirectional cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the requirements by grinding. However, the life and reliability of this repair unidirectional cylinder are not high.

The material, shape and compression of the unidirectional cylinder seal have a great impact on the service life and work efficiency of the unidirectional cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

Answers to some questions about unidirectional cylinder:

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
