(Turkey unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to unidirectional cylinder:

When the unidirectional cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the unidirectional cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

When the unidirectional cylinder needs to be stored for a period of time, please follow the recommended methods: The unidirectional cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the unidirectional 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 unidirectional cylinder should not be in direct contact with water vapor for a long time. The unidirectional cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the unidirectional 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 unidirectional cylinder Before working, the unidirectional cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the unidirectional cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

If the seal of the unidirectional 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 unidirectional cylinder, and the phenomenon of "pulling the unidirectional 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.

If the unidirectional cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the unidirectional cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow unidirectional cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the unidirectional cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the unidirectional cylinder includes the leakage caused by excessive wear of the unidirectional cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials 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 unidirectional cylinder, and the phenomenon of "pulling the unidirectional cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about unidirectional cylinder:

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.
