(El Salvador yg series hydraulic cylinder,produced by Hebei Hengyu company）
yg series hydraulic cylinder are widely used in El Salvador，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed yg series hydraulic cylinder for customers from El Salvador.
When purchasing the yg series hydraulic cylinder, try to clarify the following parameters of the yg series hydraulic cylinder: A. yg series hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or yg series hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right yg series hydraulic cylinder type can be found accurately and quickly.
yg series hydraulic cylinder installation precautions: Before installing the yg series hydraulic cylinder into the system, the parameters on the yg series hydraulic cylinder label should be compared with the parameters when ordering. The base of the yg series hydraulic cylinder must have sufficient stiffness, otherwise the yg series hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
When the yg series hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The yg series hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the yg series hydraulic 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 yg series hydraulic cylinder should not be in direct contact with water vapor for a long time. The yg series hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the yg series hydraulic 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 yg series hydraulic cylinder Before working, the yg series hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the yg series hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
The machining accuracy of the yg series hydraulic cylinder depends on the level of equipment, production technology and testing means. yg series hydraulic 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.
How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.
How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.
