(Algeria hydraulic telescopic cylinder,produced by Hengyu Group）
hydraulic telescopic cylinder are widely used in Algeria，because of no need for deceleration device，excellent fatigue and impact resistance，powerful torque.So our company has designed hydraulic telescopic cylinder for customers from Algeria.
The main role of the hydraulic telescopic cylinder: the hydraulic telescopic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the hydraulic telescopic cylinder realizes reciprocating motion. The structure of the hydraulic telescopic cylinder has three categories: piston hydraulic telescopic cylinder, plunger hydraulic telescopic cylinder, swing hydraulic telescopic cylinder, piston hydraulic telescopic cylinder and plunger hydraulic telescopic cylinder to achieve reciprocating linear motion, output speed and thrust, swing hydraulic telescopic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the hydraulic telescopic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The hydraulic telescopic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
When the hydraulic telescopic cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.
If it is found that the hydraulic telescopic cylinder lubrication is poor or the hydraulic telescopic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the hydraulic telescopic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the hydraulic telescopic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the hydraulic telescopic cylinder center line. In this way, when the piston works in the hydraulic telescopic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the hydraulic telescopic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The definition of the minimum stable speed refers to the minimum movement speed of the hydraulic telescopic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the hydraulic telescopic cylinder that undertakes different work has different requirements for the minimum stable speed.
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.
What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
