Dominica hydraulic cylinder,servo cylinder manufacturer,servo cylinder

(Dominica servo cylinder,produced by Hebei Hengyu company）

servo cylinder are widely used in Dominica，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed servo cylinder for customers from Dominica.

Introduction to servo cylinder:

The servo cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

The machining accuracy of the servo cylinder depends on the level of equipment, production technology and testing means. servo cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

When the servo cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the servo cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

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

Answers to some questions about servo cylinder:

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
