Sri Lanka hydraulic cylinder,tension cylinder manufacturer,tension cylinder

(Sri Lanka tension cylinder,produced by Hebei Hengyu company）

tension cylinder are widely used in Sri Lanka，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed tension cylinder for customers from Sri Lanka.

Introduction to tension cylinder:

The tension cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the tension cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The tension cylinder is basically composed of tension cylinder and tension cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

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

tension cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the tension cylinder is placed for a period of time, the tension cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

tension cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the tension cylinder head itself is the guide sleeve of the piston rod, the tension cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the tension cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Answers to some questions about tension cylinder:

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.

Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!
