(Ethiopia series synchronous cylinder,produced by Hengyu Hydraulic Co., Ltd）

series synchronous cylinder are widely used in Ethiopia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed series synchronous cylinder for customers from Ethiopia.

Introduction to series synchronous cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the series synchronous cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

When the series synchronous cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the series synchronous cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

If the series synchronous 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 series synchronous cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow series synchronous cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the series synchronous cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the series synchronous cylinder includes the leakage caused by excessive wear of the series synchronous 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 series synchronous cylinder, and the phenomenon of "pulling the series synchronous cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

series synchronous cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Answers to some questions about series synchronous cylinder:

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
