Congo double discharge cylinder

(Congo double discharge cylinder,produced by Hengyu Group)

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

Introduction to double discharge cylinder:

If the seal of the double discharge cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and double discharge cylinder, and the phenomenon of "pulling the double discharge cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

The "O" ring can be used as an auxiliary seal inside the double discharge cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the double discharge cylinder, and can be completely sealed.

The double discharge cylinder is mainly composed of body, piston, piston rod, double discharge cylinder head, double discharge cylinder bottom, piston rod head and related auxiliary devices. The piston divides the double discharge cylinder into two chambers, and moves reciprocally in the double discharge cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the double discharge cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the double discharge cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the double discharge cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the double discharge cylinder bottom and the double discharge cylinder head is serious, so the buffer deceleration should be set at both ends of the double discharge cylinder The working medium of the double discharge cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; double discharge cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the double discharge cylinder: The buffer structure of the double discharge cylinder is to prevent the piston from colliding with the double discharge cylinder head at the end of the stroke.

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

Answers to some questions about double discharge cylinder:

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
