Congo hydraulic cylinder,retractable cylinder manufacturer,retractable cylinder

(Congo retractable cylinder,produced by Hebei Hengyu company）

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

Introduction to retractable cylinder:

The meaning of the retractable cylinder model marked by the retractable cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the retractable cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the retractable cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

In the process of using the retractable cylinder, sometimes such a problem will occur, the retractable cylinder can not act immediately after the instruction of the retractable 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 retractable 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.

How to determine the working pressure of the retractable 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, retractable 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.

The pressure of the sliding surface of the retractable cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the retractable cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

Answers to some questions about retractable cylinder:

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.

What is the function of the forklift truck cylinder and how does it work?
(1) In order to quickly and conveniently pick up the goods, the gantry needs to be tilted forward; In order to prevent the goods from falling, the door frame should be tilted backward to ensure the stability of the goods. The front and back tilt of the frame is accomplished by tilting the oil cylinder. (2) The inclined cylinder is composed of a piston, a cylinder block, a piston rod, an upper cover, a lower cover, a compression nut and a cover female and other main parts. (3) The inclined cylinder has two oil holes that can be interchanged into oil inlet and discharge holes. The cylinder is divided into a front cavity and a back cavity by a piston. The back cavity is filled with high-pressure oil when it tilts forward, and the front cavity is filled with high-pressure oil when it tilts backward.
