(Ireland double rod cylinder,produced by Hengyu Hydraulic Cylinder Factory）

double rod cylinder are widely used in Ireland，because of no need for deceleration device，long service life，smooth movement.So our company has designed double rod cylinder for customers from Ireland.

Introduction to double rod cylinder:

The double rod cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

When the double rod cylinder needs to be stored for a period of time, please follow the recommended methods: The double rod cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the double rod cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil double rod cylinder should not be in direct contact with water vapor for a long time. The double rod cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the double rod cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the double rod cylinder Before working, the double rod cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the double rod cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When the initial action of the double rod cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the double rod cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

The double rod cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure double rod cylinder can use 20 steel pipe, and the high pressure double rod cylinder can use 45 steel pipe.

Answers to some questions about double rod cylinder:

The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.

What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
