(S.Africa series synchronous cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to series synchronous cylinder:

When installing the series synchronous cylinder pipe, the pipe should be cleaned after installation, and should not pass through the series synchronous cylinder block, and the by-pass pipe must be installed in front of the oil port of the series synchronous cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the series synchronous cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the series synchronous cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

The internal leakage of the series synchronous cylinder should be prevented when the series synchronous cylinder is used. The internal leakage of series synchronous cylinder includes the leakage caused by excessive wear of series synchronous cylinder block seal, piston rod and seal cover seal and 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.

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.

The repair method of the series synchronous cylinder: the repair of the series synchronous cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

Answers to some questions about series synchronous cylinder:

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.

The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.
