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

Introduction to series synchronous cylinder:

If the piston rod and series synchronous cylinder are stuck or the series synchronous cylinder is blocked, at this time, no matter how to operate, the series synchronous cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the series synchronous cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The series synchronous 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 series synchronous cylinder can use 20 steel pipe, and the high pressure series synchronous cylinder can use 45 steel pipe.

When the series synchronous cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the series synchronous cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

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.

Answers to some questions about series synchronous cylinder:

Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
